PROTECTION DEVICE FOR TESTING catenary AC-fault disconnected from the RAIL SUPPORT

摘要

The utility model is designed to contact network protection testing AC short-circuit on rails detached from the support. The apparatus comprises made of two electrically isolated from each other by parts of the frame and secured to the support catenary. On one part of the frame is fixed electrically isolated ground, where available equipment for registration of emergency processes. On the other side of the frame mounted control unit and switches to be played on the catenary poles short-circuit mode. The apparatus for measuring current and voltage is mounted on the bus bar, one end of which is connected to the first switch and the other end is electrically connected with the body of the catenary supports and equipment for emergency registration processes. A second switch contact is coupled to the network using the loop. Improving device mobility is achieved by providing its compactness and autonomy, as well as improving the accuracy of measurements of electrical quantities and at electrical tests. 4 ZP f-ly.
