Abstract

The invention provides a spatial discharge positioning array. The spatial discharge positioning array comprises an antenna fixing device, a signal processing device and at least four sensors, wherein the antenna fixing device comprises a first supporting arm, a second supporting arm and a third supporting arm. The first supporting arm and the second supporting arm are arranged at two sides of the third supporting arm and are connected with the third supporting arm in a manner of an obtuse angle therebetween. The first end of the first supporting arm and the first end of the second supporting arm are connected with end of the third supporting arm. The first supporting arm and the second supporting arm are connected with sensors. The third supporting arm is provided with at least two sensors in the length direction. The signal processing device is electrically connected with the sensors for determining the position of a spatial discharge power supply. The spatial discharge positioning array provided by the invention can increase distances between a plurality of sensors and time delay difference of a plurality of sensors in receiving an electromagnetic signal, and therefore the spatial discharge positioning array improves positioning precision of a positioning device.

Description

technical field [0001] The invention relates to the technical field of positioning devices, in particular to a space discharge positioning array and a method for determining the position of a space discharge source. Background technique [0002] With the progress of the times, the power grid has penetrated into all aspects of people, so the safe operation of power equipment has always been highly valued by people, and the main threat to the safe operation of power equipment is its own insulation performance, among which partial discharge of power equipment is the most important factor. The main factor of the insulation performance of power equipment. [0003] At present, there are roughly two methods of partial discharge monitoring at home and abroad, namely contact and non-contact. Among them, the contact type is to connect the detection equipment with the equipment under test for direct detection. This method often has the inconvenience of long time consumption, heavy wor...
