Description

Capacitor tripping device, uninterruptible power system and battery state monitoring display device

In the power distribution system, the high-voltage circuit breaker disk is a very important equipment and is valued. According to the certification requirements of Article 401 of the House Equipment Regulations, the high-voltage facilities, from the cabinet, high-voltage transformer, circuit breaker, voltage regulator, and current comparator , lightning arresters, high-voltage fuses, etc., must be verified. It is reasonable to say that the high-voltage system should be very reliable and has high safety and reliability. However, in practice, the situation of high-voltage power users is faulty. In the discussion, there are many cases found. The crux of the problem is that the high-voltage system provides the power supply disability of the tripping circuit, which causes an accident! It has been found that in high-voltage systems, the system provides a system that can safely isolate accidents from tripping circuit power components. For example, the capacitor tripping device CTD does not require any verification nor standard specifications. The UPS characteristics and internal battery problems of the uninterruptible power system must be addressed. The review, battery test and maintenance issues have indeed become a dead end in safety. When the related component fails, the system cannot operate due to lack of electric energy to isolate the high-voltage accident, and the consequences are quite serious, and even cause compensation problems. At present, there is no working power supply for the high-voltage disk tripping circuit on the market, and an effective monitoring device is provided externally and an effective solution is provided.

In the high-voltage system, the problem of the working power of the tripping circuit must be addressed and solved to ensure the stability of the power supply quality. A simple analogy, taking the well-known low-voltage form-cause circuit breaker MCCB as an example, MCCB's main function is in addition to the normal open/close action, when overload and short-circuit faults occur. When you are alive, you must jump off to protect the line and equipment to achieve the function of isolation accidents (if the leakage circuit breaker is added with leakage protection function). If the power failure of the trip circuit is disabled, the whole function of the high-voltage circuit breaker is lost, and there is no protection. The electronic protection power supply does not work, and there is no fault signal output; the circuit breaker has no driving power supply. The action can't jump off, just like the low-voltage circuit breaker's internal tripping mechanism is faulty, and it can never jump when the line fault occurs.

Taking the CTD of the capacitor tripping device as an example, the entire high-voltage disk is often overlooked. Most of the manufacturers are basically buying cheap products under the cost considerations. At present, the CTD capacity of the capacitor jumper is sufficient to carry the load, can not be verified and not valued, and there is no functional requirement to test whether the product is used. Appropriate (whether it is self-inspection before leaving the factory or preventive detection measures taken after the installation is completed), it is expected to be repaired once a year to find the problem. If there is an abnormal accident, there is always a long-distance water that cannot save the potential risk of near fire. The quality of the CTD of the capacitor-capacitor tripping device is very impressive. (The definition of the CTD quality of the capacitor tripping device is: when the system is in an accident, the CTD of the capacitor tripping device cannot provide an effective emergency power supply, and the protective power is activated to drive the circuit breaker to jump. Detach, isolate the accident point.), and most of the marks are unclear, and it is impossible to understand the condition of the CTD of the capacitor tripping device by means of self-operating detection. In the case of equipment such as high-voltage equipment, it is very unfair to the owner (user). It seems like a car with a beautiful appearance and good performance. When the car can't confirm whether the two functions of the direction light and the brake are normal, it is a bad one and cannot be safely on the road. In the same way, the same problems and conditions as the capacitor tripping device CTD in the problem of the UPS and the battery pack of the uninterruptible power system.

The high voltage disk trips the loop working power supply, wherein the principle of the DC disk is that the battery pack provides the system DC power supply. The suitable place for the DC disk is the 69KV, 161KV ultra-high voltage control power supply, the system is huge, and the number of circuit breakers (CB) is large. The advantages of the DC disk are (1) high stability, (2) Europe and the United States The usual way of using home, (3) the bigger the system, the more obvious its function. The disadvantages of the DC disk are (1) large space requirements, (2) less economical, less economical, (3) higher maintenance and repair costs, and (4) battery characteristics are difficult to understand, will instantly lose Energy, (5) lead acid battery has acid gas and corrosiveness, (6) nickel cadmium battery has environmental concerns, (7) lithium iron battery control board quality doubts; capacitance jump device CTD principle is PT secondary side The power input is rectified and the capacitor is charged to store the DC output. The suitable place for the capacitor tripping device CTD is to use the PT secondary side circuit as the working power source (electronic power) in the high voltage system. Capacitor tripping device CTD has the advantages of (1) the most economical when the circuit is small, (2) the cheap supply, (3) easy installation and maintenance, and (4) long life and easy identification. The disadvantage of the capacitive tripping device CTD is that each disk must be installed to occupy the disk space. The principle of the UPS system is that the AC power input is charged and discharged by the internal electronic circuit, and then the AC or DC output is converted. The applicable place of the UPS of the uninterruptible power system is to use the PT secondary side circuit as the working power source (conventional turntable type protection electric 驿) AC/AC in the high voltage system. The advantages of the UPS system are (1) the price is not expensive, (2) the supply is sufficient, and (3) the installation is simple. The shortcomings of the UPS system are: (1) The high-voltage disk is used for 10 years, 20 years, and 30 years, and the life of the UPS internal charge and discharge battery is 1-2 years. Therefore, the UPS of the uninterruptible power system is not suitable for the working power supply of the electronic electric shovel, and (2) the battery of the charging and discharging battery, such as the general battery, will have insufficient stability of instantaneous disabling.

For the uninterruptible power system UPS can not be used as the operating power of the high voltage disk tripping circuit: the general protection electronic power 驿 its burden capacity will generally not exceed 30VA, so the UPS of the UPS system used in this place is generally small and constant Electrical system UPS. The working principle is AC power input, which is input to the charging and discharging battery unit after being controlled by the electronic circuit, and then outputted by the AC power source. The battery unit is charged and discharged, and its battery life is about 1-2 years, and the battery is not easy to detect the phenomenon of attenuation, like a battery of a motorcycle or a car, and it is instantaneously disabled. The high-voltage switchboards are often used for 10 years and more than 20 years. In the case of equipment such as high-voltage switchboards, protection of power and disconnection The reason why it can jump off the loop working power supply, can not use the uninterruptible power system UPS here. (Note: For the old rotary disc type protection electric power supply using AC power supply, the uninterruptible power system UPS can be considered as one of the options for emergency working power supply.) In addition, the Chinese name of the UPS system is called the uninterruptible power system. But in fact, when the power is cut off, the normal power supply is switched to the uninterruptible power system, and there is a time difference of switching, which is generally 4-20ms. In the case of general commercial and household electricity quality, it is a situation that may be tolerated. However, if it is on the high-voltage power distribution system, when the switching time of the UPS of the uninterruptible power system is 4-20ms and the reaction time of the protection power is 4-20ms, the total time may be greater than the secondary side three-phase short circuit of the high voltage system. , the time at which the fault point is formed. Such a high-voltage disk can not be effectively powered off immediately to isolate the accident point, resulting in European countries and Japan ... and other countries mandatory regulations UPS equipment This equipment should not be used as the working power supply for the high-voltage power distribution system trip circuit.

Capacitor tripping device, uninterruptible power system and battery pack condition monitoring display device should have three basic requirements: (1) It can be tested under load: It is an important function of the high voltage disk to isolate the accident when the fault occurs, so the owner must be able to Have a clear understanding of the situation, and can test at any time under load, to know if the system is normal? It does not affect the normal power supply operation. Be able to test when the power is normal. Is the equipment available? (Does it be necessary to check for faults or accidents?) (2) Conditional indicating device: Capacitor tripping device CTD This product must enable the user to clearly understand whether the system can normally trip when the system is faulty. To be able to grasp the status of product performance, in order to facilitate interpretation and replacement. (3) There are practical and safety requirements: easy to install, it is best not to open the high voltage disk surface, and do not move to the control circuit during testing to prevent electric shock, electric shock or malfunction, etc.; The monitoring function is even better.

Capacitor tripping device, uninterruptible power system and battery pack condition monitoring display device have the above three basic functions, improve the problems of old components, prevent the recurrence of industrial safety accidents, and change It is very important and urgent. In particular, the high-voltage disk tripping circuit power supply, whether using the capacitor tripping device CTD or the uninterruptible power system UPS or battery pack, may face disconnection and power failure, etc., or attenuation or insufficient capacity to cause disability The situation.

In summary, for high-voltage power distribution systems, it is very important to provide HVCB tripping circuit power supply for high-voltage circuit breakers, which is an important issue that is often overlooked in high-voltage switchboards. Especially in the old equipment, the capacitor tripping device CTD, the uninterruptible power system UPS, and the battery pack, whether it can provide normal power to operate the high voltage disk tripping loop normal operation, one can monitor the capacitance tripping device CTD, uninterrupted power The system UPS and battery pack status devices are very important, especially in combination with the current smart energy-saving switchboards, which will solve the problems that cannot be solved by the residence.

When the switch 13 is turned off, the output voltage of the capacitor trip device CTD, the uninterruptible power system UPS, and the battery pack is connected to the comparison circuit 32 of the internal control signal 12 via the OC, OU, and OB terminals for comparison, when the voltage is higher than one. The default value is normal. If the preset value is lower than the preset value, the corresponding warning action is performed. If the warning contact 26 is turned on, the relative warning indicator light 27 is activated to remind the user that the power supply of the circuit is faulty. When the automatic test switch 16 is pressed, the circuit of the changeover switch 13 periodically turns off the power supply of the external AC power supply 11 for a preset time until the time of the time circuit 33 is preset to be turned off. This periodic disconnection of the external AC power source 11 is performed cyclically. When the changeover switch 13 turns off the external AC power supply 11, the same action as that of the hand test is performed. The difference is only automatic when the test action is cyclic. When the switch 13 is turned off, the output voltages of the capacitor trip device CTD, the uninterruptible power system UPS, and the battery pack are connected to the comparison circuit 32 of the internal control circuit 12 via the OC, OU, and OB terminals for comparison, when the voltage is higher than a pre-control Set to normal. If it is lower than the preset value, the corresponding warning action is performed. If the warning contact 26 is turned on, the relative warning display light 27 is activated to remind the user that the power supply of the loop circuit generates a fault fault signal and can be connected to the connection terminal 28 by the RS485 monitoring point. Send it out. During the test, the voltage of the capacitor tripping device CTD, the uninterruptible power system UPS and the battery pack are synchronously displayed to indicate the voltage state. Table, such as a 25, 29 or 30 meter. The protection device 34 is a general thermistor, surge absorber or related component to avoid transient voltage variations damaging the component.

Figure 7 is a further illustration of the flow chart of the operation of the apparatus 10 of the present invention. According to the description of FIG. 6 , the circuit configuration is completed. At this time, the device of the present invention first determines whether the manual test switch 15 is pressed. If yes, it indicates that the manual test function is executed, the switch 13 is executed, and the device is disconnected and sent to the device under test (CTD, UPS). The external AC power source 11 of the Battery, the time circuit 33 starts the counting of the off time (the time circuit is preferably executed by the microcontroller). Then, it is detected whether the automatic test switch 16 is pressed. The automatic test means that the external AC power supply 11 is automatically turned off for a predetermined off time every predetermined period to detect whether the device under test is faulty. If the automatic test switch 16 is pressed, the time of the periodic switch 13 operation is performed. When the off time of the automatic or manual test has expired, the control switch 13 is returned to the on state. Otherwise, the output voltage of the device under test is displayed. At the same time, the output voltage is compared by the voltage comparison circuit 32. If the voltage value is lower than the set value, it indicates that the device is faulty, and the warning indicator lights 26, 27 are driven to perform the warning action, and the comparison state is stored. The relevant device under test status is displayed by the corresponding light number. The operation of the comparison circuit and the storage of the comparison result state are preferably performed by a microcontroller. When the remote host has a read device status request, the RS485 monitoring point output connection terminal can transmit the required signal to provide an instant status of the device under test.

In summary, the present invention can solve the problem in the market that it is impossible to monitor the power supply of the tripping circuit of the device in the disk, which can solve (1) power failure, (2) attenuation, and (3) insufficient capacity.
