Abstract

The invention discloses a partial discharging signal source positioning device and system of a gas-insulation completely-enclosed combined electrical appliance. The device comprises a first detector, a second detector and a receiver. The first detector is used for detecting partial discharging signals to acquire first signals; the second detector is used for detecting the partial discharging signals of the partial discharging signal source to acquire second signals; the receiver receives the first signals and the second signals in a manner of wireless communication and determines the location of the partial discharging signal source according to the first signals and the second signals. By the aid of the device, the problem that a GIS partial discharging monitoring system is complex in structure in the prior art is solved, and the effect of simplifying the GIS partial discharging monitoring system structure is achieved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a positioning device and system for a partial discharge signal source in a gas-insulated fully enclosed combined electrical appliance. Background technique [0002] With the rapid development of my country's power industry construction, the modern power system is developing in the direction of large power grids, large units, ultra-high voltage, and large capacity. In order to ensure the stability and reliability of the power system, more safety requirements for power equipment are also proposed high demands. [0003] The safe operation of high-voltage electrical equipment is crucial to the stability of the power system, and it is necessary to pay attention to and strengthen its detection work. GIS (Gas Insulation Switchgear, referred to as GIS) is a gas-insulated fully enclosed combined switchgear, which is very common in power grids and large substations. Partial discharge of G...
