Abstract

The invention provides a device and a method for positioning a fault of urban rail transit overhead contact line equipment, wherein the device and the method relate to the field of power grid monitoring. The device comprises a DC transmitter, a double-side tripping device and a DC traction measuring and controlling protecting device. The DC transmitter detects current information and voltage information of the urban rail transit overhead contact line equipment and furthermore transmits the detected current information and the voltage information to the DC traction measuring and controlling protecting device. The DC traction measuring and controlling protecting device determines the position of the fault of the urban rail transit overhead contact line equipment according to the detected current information and the voltage information. The device and the method according to the invention have advantages of realizing high speed in finding the position of the fault, and improving fault positioning efficiency.

Description

technical field [0001] The invention relates to the field of power grid monitoring, in particular to a device and method for fault location of an urban rail transit catenary. Background technique [0002] At present, the power supply system of the catenary similar to the rail transit of the subway is no longer a single-ended power supply method or a simple double-ended power supply method, but a double-ended power supply method with bilateral switching between large and small, and its power supply system becomes correspondingly complicated. When the power supply system fails, it is very difficult to find the fault quickly and accurately. [0003] In the existing power supply mode, after a failure occurs, the on-site inspection is carried out manually. This will cost a huge amount of human and material capital and take a long time, so the efficiency of transportation is reduced. Contents of the invention [0004] The object of the present invention is to provide a device ...
