Abstract

The invention belongs to the technical field of high voltage equipment, and discloses an insulator surface potential measuring system and a measuring method based on a multi-sensor system. An insulator rotating unit and a probe three-dimensional moving unit are arranged inside a gas-tight box body; the gas-tight box body is filled with a gas simulating the true working condition of the insulator;the insulator rotating unit makes the insulator complete the rotation; the probe three-dimensional moving unit enables an electrostatic probe to complete two-dimensional translation and rotation in avertical plane; an electrometer reads the surface potential data of the insulator through the electrostatic probe and uploads the data to an upper computer for storage; and thus, insulator surface potential measurement is completed. Two kinds of translation and one kind of rotation of the electrostatic probe and one kind of rotation of the insulator can be realized, the measurement process is multi-dimensional and the space is controllable; the electrostatic probe and the insulator can be precisely controlled, and the measurement result has a high spatial resolution; and the gas pressure and voltage working environment of a real gas-sealed insulator can be simulated at the same time, and the measurement result is close to the real situation.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to an insulator surface potential measurement system and a measurement method. Background technique [0002] Gas-insulated switches (GIS) and gas-insulated lines (GIL) and other gas-insulated equipment have become the mainstay of power systems because of their advantages such as good stability, high reliability, small size, small footprint, no influence from the external environment, and simple maintenance. widely used equipment. At present, with the rapid development of UHV DC transmission projects in my country, the application requirements of DC gas-insulated equipment in power systems are also increasing. However, in DC gas-insulated equipment, under the action of unipolar voltage for a long time, the surface of the insulator is easy to accumulate charges, which affects the safe and stable operation of DC gas-insulated equipment. [0003] The part of the gas-sol...
