Definitions

  • the invention relates to an on-load tap-changer with a motor drive.
  • the applicable standards stipulate that the motor drive has rotation monitoring and has means to ensure automatic termination of a changeover in the direction it has started. This requires a direction of rotation information.
  • a rotating field control relay for monitoring the direction of rotation and a bistable relay (surge relay) is used for automatic termination of a once started switching.
  • these electronic components are expensive on the one hand and problematic on the other in harsh environmental conditions.
  • the object of the invention is therefore to provide an on-load tap-changer with motor drive of the type mentioned, in which the described safety requirements are realized in a simple and cost-effective manner.
  • the on-load tap-changer has various novel features which, in combination with each other, meet the described requirements of Slayerhelts.
  • the direction of rotation monitoring and the restart of the motor drive are derived from essentially existing messages. It is particularly advantageous that no additional mechanical components are needed anymore; Both the described rotating field control relay and the bistable relay can be omitted without replacement.
  • inductive proximity sensors are provided on the load changeover switch of the on-load tap-changer, which detect its position.
  • means for EntklinkungsGermanwachung are arranged on the linkage between the motor drive and on-load tap changer having cam switches. Furthermore, means for mechanical running message of the motor drive are provided; This is detected by means of a direction-independent cam track directly on the selector drive. Finally, electrical means for running message of the (known) motor contactors are provided.
  • FIG. 1 shows how the position of the diverter switch is detected by inductive proximity sensors S70, S71 on the diverter switch. In this case, an even / odd message is generated, which is multiplied by auxiliary contactors K13 and K14, which are explained below.
  • the diverter switch itself switches about 20 degrees before the end of a circuit. It is assumed in the entire embodiment on a total rotation angle at each load switching of 360 degrees.
  • FIG 3 the means for mechanical running message of the motor drive are shown. It is a direction-independent acting cam track shown, which is located directly on the selector drive.
  • a cam switch S13 switches off 35 degrees after the start of the switchover and 35 degrees before the end of the switch again. The movement of the selector itself begins only at a rotation angle greater than 35 degrees.
  • the control itself operates on the principle of stepping and meets the requirements of IEC 60214.
  • the two motor contactors K1, K2 control the motor in different directions of rotation, the motor protection switch Q1 protects this motor from overload and has a trip coil for shutdown. All degrees used below refer in turn to a complete rotation angle of 360 degrees per switching.
  • the diverter switch is in odd position, S71 actuated, K14 energized and S23 actuated. After activating the motor contactor K2, the motor M1 starts in the direction "right". After 25 degrees, the unlatching monitoring cam switch has reached the position it retains throughout the test phase (35 degrees ... 325 degrees). Starting from Figure 2, the states do not change in this case; S23 remains actuated, S24 not actuated.
  • the cam switch S13 ( Figure 3) is operated at 35 degrees and activates the check and restart phases.
  • the diverter switch is in odd position, S71 actuated, K14 energized and S23 actuated. After activating the motor contactor K1, the motor M1 starts in the direction "left". After 25 degrees, the unlatching monitoring cam switch has reached the position it retains throughout the test phase (35 degrees ... 325 degrees). Starting from FIG. 2, S24 is actuated; S23 drops back. The cam switch S13 ( Figure 3) is operated at 35 degrees and activates the check and restart phases.
  • the diverter switch is in the straight position, S70 actuated, K13 energized and S24 actuated.
  • the motor M1 After activating the motor contactor K2, the motor M1 starts in the direction "right".
  • the unlatching monitoring cam switch has reached the position it retains throughout the test phase (35 degrees ... 325 degrees).
  • the states do not change in this case; S24 remains actuated, S23 not actuated.
  • the cam switch S13 ( Figure 3) is operated at 35 degrees and activates the check and restart phases.
  • the NC contactor K14 opener (not activated) for multiplying the position signal of the diverter switch, voltage is applied to the cam switch S23 (activated). If, due to the correct direction of rotation S23 is not activated, voltage is applied to the coil of the motor contactor for direction "left" K2; the restart is guaranteed until the cam switch S13 drops out. Is S23, z. If, for example, due to a wrong rotating field at the connection terminals, the motor protection switch Q1 is triggered by connecting the cam switch S13 via the auxiliary contact of the motor contactor K2: 53-54.
  • the diverter switch is in the straight position, S70 actuated, K13 energized and S24 actuated. After activating the motor contactor K1, the motor M1 starts in the direction "right”. After 25 degrees, the unlatching monitoring cam switch has reached the position it retains throughout the test phase (35 degrees ... 325 degrees). Starting from FIG. 2, S23 is actuated, S24 drops back.
  • the cam switch S13 ( Figure 3) is operated at 35 degrees and activates the check and restart phases.
