Description

Portable EMUs high tension cable partial discharge detection device

Technical Field

The utility model relates to a high tension cable check out test set field, in particular to portable EMUs high tension cable partial discharge detection device.

Background

Along with the rapid development of high-speed rail motor train units in recent years, the problem of running safety of the motor train units is more and more prominent and important, and particularly the running of the motor train units in the whole train is directly influenced at the front end of a power supply system of the motor train units. At present, a motor train unit is generally subjected to effective detection and maintenance aiming at a pantograph and a power supply circuit after a main break in daily operation and maintenance, but a high-voltage cable between the pantograph and the main break is not provided with an effective detection facility, the problem that the end insulator and the joint of the high-voltage cable are subjected to visual inspection and sanitary treatment only in static operation and maintenance is solved, the operation state of the cable in a dynamic process cannot be detected, the local discharge phenomenon of the high-voltage cable often occurs, the high-voltage cable is rapidly aged or burnt out, and even the high-voltage cable is blown out by touching a network. Therefore, the partial discharge condition of the high-voltage cable at the section can be detected quickly, effectively and safely, and the safe operation of the motor train unit can be improved and guaranteed.
