Abstract

The invention DC60 involves a method for the shutdown of the current between adjacent stators. Of a railway system consisting of Rails and vehicles, and with long stator linear motors.This invention follows the traditional double-feed step change method. During the closing and opening of the circuit Of the current from one stator section of the phase of the long stator winding to the subsequent section cable, which is assigned to the stator section to be replaced And was supplied by power from two substations The station with double infeed is separated. In this way, the transformed time can be supplied with single feed by a single substation in each case. It is possible to avoid the loss of one-sided thrust which occurs in the case of Traditional procedure replacement method The invention involves a method for closing and opening of an electric circuit between adjacent stators.
