Abstract

The invention discloses a vehicle-mounted cable terminal partial discharge detection device and method. The vehicle-mounted cable terminal partial discharge detection device comprises an experiment module, a measurement module and a background communication module which are sequentially connected through signals. The experiment module comprises two same insulating oil test boxes used as experiment containers; a ventilation cooling device, an impurity filtering device and a safety early warning device are arranged in each insulating oil test box; and a cable core at one end of a cable terminal in one insulating oil test box is connected with a high-voltage power supply through a high-voltage wiring end, and a cable in the other insulating oil test box is sequentially connected with a grounding wire, a grounding end and an external grounding electrode. The insulating oil test box is internally provided with a circulating ventilation port, a temperature and impurity monitoring device and a gas monitoring device, so that the experiment can be safely carried out, the measurement information can be directly transmitted to a computer, the measurement process is convenient and safe, and the partial discharge detection requirement of the vehicle-mounted cable terminal can be met.

Description

technical field [0001] The invention belongs to the technical field of high-voltage experiments on vehicle-mounted cable terminals, and in particular relates to a partial discharge detection device and method for vehicle-mounted cable terminals. Background technique [0002] Vehicle-mounted high-voltage cables are key high-voltage equipment in high-speed trains and electric locomotives. High-voltage cables complete the connection of various high-voltage electrical equipment in the vehicle-mounted power supply system. With the rapid popularization of high-speed trains, high-speed trains have higher and higher requirements for the operation of electrical equipment, because a part of the high-voltage cables on the vehicle is completely exposed to the air during operation, and China has a vast territory, and the geographical environment in which the vehicles run is relatively complex. In order to prevent cable damage accidents that may occur during operation, the requirements fo...
