Definitions

  • the invention relates to an on-load tap changer with a motor drive.
  • the applicable standards such as IEC 60214 and VDE 0532 stipulate that the motor drive has a direction of rotation monitoring and has means that ensure an automatic termination of a switchover in the direction once started. This requires information about the direction of rotation.
  • the known on-load tap-changer uses a rotating field control relay for monitoring the direction of rotation and a bistable relay (current surge relay) for automatically ending a changeover that has already started.
  • bistable relay current surge relay
  • the object of the invention is therefore to provide an on-load tap changer with a motor drive of the type mentioned in the introduction, in which the described safety requirements are implemented in a simple and inexpensive manner.
  • the on-load tap-changer has various new features which, in combination with one another, meet the safety requirements described.
  • the direction of rotation monitoring and the restart of the motor drive are essentially derived from existing messages. It is particularly advantageous that no additional mechanical components are required; Both the described field control relay and the bistable relay can be omitted without replacement.
  • inductive proximity sensors are provided on the diverter switch of the on-load tap changer, which detect its position. Furthermore, means for unlatching monitoring are arranged on the linkage between the motor drive and on-load tap changer, which have cam switches.
  • Means are also provided for the mechanical running signal of the motor drive; this is recorded directly on the selector drive using a direction-independent cam track. Finally, electrical means for reporting the running of the (known) motor contactors are provided.
  • Figure 1 shows the arrangement of the inductive proximity sensors
  • FIG. 2 shows the means for unlatching monitoring on the linkage between the motor drive and on-load tap-changer.
  • FIG. 3 shows the means for mechanical running signal on the selector drive
  • FIG. 4 shows a complete circuit diagram of the motor drive as part of the on-load tap-changer according to the invention
  • FIG. 5 shows a circuit extract with safety devices
  • FIG. 6 shows a schematic switching sequence when switching from one winding tap of the dry-type transformer to another (adjacent) winding tap.
  • FIG. 1 shows how the position of the diverter switch is detected by inductive proximity sensors S70, S71 on the diverter switch. An even / odd message is generated, which is multiplied by auxiliary contactors K13 and K14, which are explained below.
  • the diverter switch itself switches approximately 20 degrees before the end of a shift. In the entire exemplary embodiment, a total rotation angle of 360 degrees is assumed for each load switchover.
  • a cam track is provided on the linkage between the motor drive and the step switch, black in the figure, which is widened in one direction by 130 degrees, so that with it corresponding cam switches S23 or S24 - depending on the current position and controlled direction of rotation - 25 degrees Switch on or off at the beginning or before the end of a switchover.
  • FIG. 3 shows the means for mechanically reporting the running of the motor drive.
  • a directionally independent cam track is shown, which is arranged directly on the selector drive.
  • a cam switch S13 switches on 35 degrees after the start of the switchover and 35 degrees before the end of the switchover. The movement of the selector itself begins at an angle of rotation greater than 35 degrees.
  • FIG. 4 shows the circuit diagram according to the invention, which also has other known components which are necessary for explaining the overall function. The same applies to the actual monitoring unit shown in FIG. 5.
  • the diverter switch is in the odd position, S71 actuated, K14 energized and S23 actuated. After activating the motor contactor K2, the motor M1 starts running in the "right" direction. After 25 degrees, the cam switch for the unlatch monitoring has reached the position that it maintains during the entire checking phase (35 degrees ... 325 degrees). Starting from FIG. 2 In this case, the states do not change: S23 remains activated, S24 is not activated. The cam switch S13 (FIG. 3) is activated after 35 degrees and activates the checking and restart phase.
  • the diverter switch is in the odd position, S71 actuated, K14 energized and S23 actuated. After activating the motor contactor K1, the motor M1 starts running in the "left" direction.

Starting from FIG. 2 S23 is actuated, S24 falls back, cam switch S13 (FIG. 3) is actuated after 35 degrees and activates the checking and restarting phase.
  • Errors in the monitoring and restarting device are automatically recognized as all contacts of the cam switches S23 and S24 are connected and trigger the motor protection switch Q1. If there is an error in the detection of the respective position of the diverter switch, either both monitoring circuits are electrically active or inactive; both trigger the motor protection switch Q1.

Abstract

L'invention concerne un combinateur de réglage en charge à commande par moteur. Pour que les fonctions de surveillance et de remise sous tension requises puissent être réalisées, le commutateur de réglage en charge présente des capteurs de proximité inductifs servant à détecter sa position, ces capteurs coopérant avec des combinateurs à cames séparés actionnés par des disques à cames selon une séquence déterminée. Selon l'invention, un contrôle de plausibilité est effectué à chaque commutation et un disjoncteur-protecteur du moteur est actionné en cas d'écart par rapport à la normale.
