Abstract
PURPOSE: To prevent a chopper unit from failure of overvoltage by not making to close the main circuit disconnector in case the inverse power instructions are given when the car speed has surpassed the fixed speed.
CONSTITUTION: Supposedly the car speed is under 5 km/h and when the forward power instructions are given, a forward switching coil RV (forward) is excited provided the main circuit disconnector is not closed to switch the reverser on a forward position. Next, the main circuit disconnector closing coil LS11 is excited through the connector 5KRb of the speed relay 5KR. When the car speed surpasses 5km/h, the auxilliary relay PR is excited through the connector 5KRa of the speed relay 5KR being simultaneously self-maintained. In case the backward power instructions R are given at the car speed above 5km/h, the auxilliary relay PR is degaussed on way to reversion of the reverser not to excite the closing coil LS11 of the main circuit disconnector.
