- On-load tap-changers have been in worldwide use for many years for uninterrupted switching between different winding taps of tapped transformers in large numbers. So-called reactor switches, which are particularly common in North America, have a switching reactance, which allows a slow, continuous switching.
- On-load tap-changers according to the resistance rapid-switching principle usually consist of a selector for powerless selection of the respective winding tap of the
- Stepped transformer to be switched to, and a diverter switch for the actual switching from the previous to the new, preselected
- the diverter switch usually has switching contacts and resistance contacts.
- the switch contacts are used for direct connection of the respective winding tap with the load dissipation, the resistor contacts for short-term wiring, d. H. Bridging by means of one or more
- a diverter switch carries a drivable by a power storage drive shaft with at least one cam.
- the cam has a plurality of control cams, two of which are arranged on the front side of the cam
- Cams have a deviating from a circular contour contour on the type of cam, on the contact-connected in each case via a rocker arm connected to a vacuum interrupter roller is guided, which taps the profiled contour of the respective control cam.
- the known from the prior art on-load tap-changer are delivered to the customer as finished assembled products and installed by this on-site in an existing tap-changer.
- Position indicator arrangements as part of the motor drive of tap changers o. ⁇ . Serve to electrically detect and transmit the respective position of the tap changer o. ⁇ . this in turn is on the one hand starting point for the actual position indicator and on the other hand as an actual value basis subsequent Steuert. Control functions.
- Known position signaling arrangements for tap changer consist of a circular arrangement of a plurality of signaling contacts, wherein at least one each reporting contact an operating position of the tap changer o.
- the like Is assigned.
- Tap changer more precisely with the motor drive of the tap changer, is in communication, wired.
- a switching angle moves, which corresponds to the distance between two adjacent signaling contacts.
- DC operated circuits are performed or generally higher currents to be switched.
- Winding tap of the control winding of the tapped transformer assigned. Again, the mechanical coupling or the adjustment of the tap changer with the
- Position indicator display according to a fixed circuit diagram done, otherwise wrong operating positions are displayed by the position indicator. Based on this, it is an object of the present invention to provide a method for determining an on-load tap changer for switching between different
- the general inventive idea is to achieve a predefined operating position of the on-load tap-changer by activating a motor drive by a parameterized control device in a first direction of rotation after start-up of the on-load tap-changer, so that the on-load tap-changer switches its stationary operating positions, ie the various winding taps of the tapped transformer Direction of the first winding tap begins to run through, by means of the control device, the achievement of the end position of the on-load tap-changer is detected, again
- the motor drive is activated in a second direction of rotation, so that the
- the method according to the invention defines
- Operating position software is stored non-volatile, so it is comprehensible at any later time, how many switches in which switching direction of the
- control device detects the mechanical end stop of the control range of the on-load tap-changer by the
- Amperage of the motor drive after its activation in a first direction of rotation is stored non-volatile and compared at defined intervals with a parameterized in the control device as a current limit value maximum value. If the currently determined current value exceeds the defined setpoint value, an electrical signal is generated which indicates to the control device the mechanical limit stop of the on-load tap-changer.
- the mechanical end stop of the control range of the on-load tap-changer is detected by the control device by means of a sensor at regular intervals the
- Rotation speed of the drive shaft of the motor drive detected. If the determined value of the rotational speed is equal to 0, an electrical signal is generated which indicates to the control device the mechanical limit stop of the on-load tap-changer.
- a signaling contact is connected when passing through the control range of the on-load tap-changer in a first direction of rotation at each reaching a next stationary operating position, wherein the
- Triggering time d. H. the circuitry of the signaling contact, by means of the control device is stored non-volatile, wherein the time between two trip times is compared with a maximum allowable limit, wherein when exceeding the maximum allowable limit, an electrical signal is generated indicating the control device, the mechanical end stop of the on-load tap changer. This can be done, for example, that with the drive shaft of the motor drive at least one
- Cam is brought into rotary engagement, which in turn actuates at least one microswitch per revolution of the cam.
- the gear ratio the gear ratio
- Microswitch thus triggers once per revolution of the cam and thus per switch, ie permissible stationary operating position of the on-load tap-changer, thus indicating a successfully completed switching process.
- the figure shows a schematic flow chart of the method according to the invention.
- the starting point of the method according to the invention is the commissioning of the
- Stepper transformer connected, mounted the motor drive and the on-load tap-changer, including motor drive to a software-based electronic control device
- control device is to be parameterized during commissioning, in particular an initial direction of movement of the drive shaft of the motor drive is to be defined, furthermore the number of permissible stationary operating positions of the on-load tap changer must be specified and finally defined, where the beginning of the control range, i. the first permissible stationary operating position, and the end of the control range, ie the last permissible operating position, the on-load tap-changer is.
- These parameters are not volatile in the controller.
- on-load tap-changers usually have a selector for powerless selection of the respective winding tapping of the tapped transformer to be switched to, and a diverter switch for actually switching from the previous to the new, preselected winding tapping.
- the on-load tap-changer underlying switch type are in a control winding with, for example, 5 winding taps after the
- Stepped transformer in the direction of the first winding tapping begins to go through.
- the first winding tapping here means the winding winding of the control winding closest to the main winding of the step transformer gate - ie the start of the control range of a tapped transformer.
- the motor drive is
- stepper motor for example, a known from the prior art stepper motor.
- the reaching of the end position by means of the control device is detected.
- end position is understood in the context of the present invention, the mechanical end stop of the on-load tap-changer, against which the moving part of the on-load tap-changer moves when he the beginning or the end of his Has reached the control range. This can be done, for example, that the
- On-load tap-changer detects by the current strength of the motor drive after its
- Time intervals is compared with a parameterized in the control device as the current limit value maximum value. If the currently determined current value exceeds the defined setpoint value, an electrical signal is generated which indicates to the control device the mechanical limit stop of the on-load tap-changer.
- the mechanical end stop of the control range of the on-load tap-changer is detected via the control device by means of a sensor in a regular
- Time intervals does not detect the rotational speed of the drive shaft of the motor drive. If the determined value of the rotational speed is equal to 0, an electrical signal is generated which indicates to the control device the mechanical limit stop of the on-load tap-changer.
- a signaling contact is connected when passing through the control range of the on-load tap-changer in a first direction of rotation at each reaching a next stationary operating position, wherein the triggering time, d. H. the wiring of the signaling contact, by means of the control device is stored non-volatile, the time between two
- Tripping times is compared with a maximum allowable limit, wherein when exceeding the maximum allowable limit value, an electrical signal is generated, which indicates the control device, the mechanical end stop of the on-load tap-changer.
- This can for example take place in that at least one cam disc is brought into rotary engagement with the drive shaft of the motor drive, which in turn actuates at least one microswitch per revolution of the cam disc.
- Gear ratio can synchronize the rotation of the cam with a
- the microswitch thus solves per revolution of the cam and thus per switching, ie permissible stationary operating position of
- the motor drive is activated by the control device in a second direction of rotation, so that the selector then adjusts the control range in the opposite switching direction until reaching the first stationary position
