Description

Intelligent low-pressure distribution electricity-saving appliance
Technical field
The utility model relates to a kind of intelligent low-pressure distribution electricity-saving appliance, is used for the automatic regulation voltage of low-voltage distribution system, saves electric energy, prolongs the electrical appliance life-span.
Background technology
In the low-voltage distribution system of 380V, voltage is to regulate with user's needs.The height of voltage is by power supply department decision, the passive acceptance of user.To the adjusting of voltage, generally the switch by the high-pressure side that is located at 10KV carries out manual adjustments or adjusting automatically.Because voltage is low, electric current very big (up to more than 2400 amperes) is so pressure regulation hardly may under load-carrying situation.Particularly in illuminator, because the daylighting degree of daytime and evening, fine day and rainy day is different, the voltage of illumination should be distinguished to some extent.On the other hand, power supply department is in order to deliver to terminal temperature difference to electric energy, so in the initial voltage stage, voltage often exceeds 5% of normal power supply, near i.e. user transformer, supply voltage is just than higher, and the user can't regulate, so wasted electric energy on the one hand, the consuming device life-span also can be affected on the other hand.
Summary of the invention
The purpose of this utility model is regulated primary circuit by secondary circuit, promptly use little electric current, higher voltage is regulated load current big in the primary circuit and low voltage, thereby reach low pressure 380V system can bringing onto load automatic regulation voltage, save electric energy, prolong the consumer electronics tool purpose in serviceable life thereby reach.
The technical solution of the utility model is: intelligent low-pressure distribution electricity-saving appliance comprises testing circuit, control circuit and voltage-regulating circuit, voltage-regulating circuit is by reactor, autotransformer, independent winding and switch are formed, one group of independent winding of series connection on the secondary induction winding of reactor, independent winding and autotransformer are unshakable in one's determination altogether, independent winding has a plurality of taps, each tap is connected with electronic switch, tap winding on the autotransformer is connected by electronic switch with independent winding, again with secondary induction windings in series, two termination power supplys of autotransformer coil, the electronic switch self-locking each other at the two ends of each winding of independent winding and autotransformer tap winding, its other end interconnects.
Reactor winding and self coupling coil adopt the conjugation-type iron core.
Beneficial effect: the 380V low-pressure system can be come setting voltage by user's oneself needs, has changed the situation of original passive electricity consumption.Realized utilizing the adjustable of the big electric current supply voltage of little current hollow system, accomplished rational utilization of electricity, saves energy, and prolonged life-span of electrical appliance.For example, in megastore and supermarket, can be provided with a brightness 9 o'clock to 12 o'clock morning, and 12 can be provided with a brightness again at 5 in afternoon, and coming off duty until 9 after 5 is provided with a kind of brightness again, so just can save a large amount of electricity charge.And the life-span of light fixture also prolongs greatly.Generally more than 1000A reached, main light fixture was conventional fluorescent light for general megastore and supermarket, lighting current, and power saving rate can reach 10%~30%.Intelligent low-pressure distribution electricity-saving appliance can prolong light fixture serviceable life, reduces the manual maintenance expense, and certain filter action is arranged simultaneously.
Description of drawings
Fig. 1 has provided physical circuit connection layout of the present utility model.
Fig. 2 has provided the synoptic diagram of reactor winding of the present utility model and self coupling coil employing conjugation-type iron core.
Embodiment
Fig. 1 has provided physical circuit annexation of the present utility model.Now further specify specific embodiment of the utility model in conjunction with the accompanying drawings:
1. the utility model comprises the reactor winding L that is connected in the low pressure using electricity system, and the pressure drop of reactor is set according to user's request, from 0~30V scalable.The reactor winding carries an induction Secondary Winding L1, on the secondary induction winding L 1 one group of independent winding of series connection or (with) self coupling coil L4, independent winding has a plurality of taps, as L2, L3, the two ends of each tap are connected with electronic switch, and the other end of the electronic switch at each winding two ends interconnects.The other end that is K1 and K2, K3 and K4, K5 and K6 interconnects.Two independent winding tap voltages adopt the voltage on permutation and combination method and the reactor to be complementary.
2. one group of autotransformer OSB in parallel in the low pressure using electricity system.Tap winding on the autotransformer is connected by electronic switch K5 with independent winding, (when range of regulation is big).
3. iron core of electric reactor T1 and autotransformer T2 unshakable in one's determination adopts the conjugation-type iron core.Reduce volume, reduced cost.
4. PLC is a Programmable Logic Controller, be used to control the break-make of electronic switch, select voltage some of the tap voltage of two independent winding L2, L3 and self coupling coil L4 by permutation and combination method or severally respond to winding L 1 with secondary and connect, K1 and K2, K3 and K4, K5 and K6 are not closed simultaneously when work, i.e. self-locking each other.(6 switches can be opened simultaneously during not pressure regulation, not self-locking this moment) like this, the deexcitation magnetoelectricity that makes induction Secondary Winding L1 go up generation is pressed adjustable by the control requirement, and the terminal voltage of reactor winding L is changed, thereby changed mains supply voltage, reached by setting voltage value and adjust automatically.
5. the setting of voltage is made by oneself by the user, voltage detection mechanism is changed by A/D, be transferred to PLC after voltage analog signal changed into digital signal, PLC compares by the magnitude of voltage that calculates and the user sets, if do not meet, PLC sends instruction, the electronic switch action of induction Secondary Winding and autotransformer and independent winding, thereby the pressure drop on the change reactor makes line voltage satisfy the set definite value of user.
