Embodiment 1

[0046] figure 1 It is a flow chart of a method for detecting gas leakage of a power switch provided in the embodiment of the present application. see figure 1 , the method includes the following steps:

[0047] S101: Establish a leakage database of the power switch, where the leakage database includes historical leakage point locations.

[0048] The leakage database is an information database of historical leakage points. When used for the first time, the information in the leakage database can be established through manual input, and then the leakage database can be established through automatic saving during use.

[0049] S102: Obtain the pressure value at the current moment in the internal environment of the power switch.

[0050] The gas volume inside the power switch is directly related to the pressure value of the power switch. If the power switch gas leaks, the gas pressure inside the power switch will decrease with the reduction of the gas volume. In a possible imp...

Abstract

The invention provides a power switch gas leakage detection method and system. The method includes the steps: building a leakage database of a power switch; acquiring a pressure valve of the current moment in the internal environment of the power switch, and judging that the power switch possibly has gas leakage when the pressure valve of the current moment is lower than a pressure threshold value; performing leakage detection on the power switch according to the leakage database when the power switch possibly has gas leakage. The leakage database comprises history leakage point positions. Relative to the prior art, when leakage is detected by the aid of infrared imaging technology, detection is blindly disordered. According to the power switch gas leakage detection method and system, compared with a historical database, leakage detection orders in power switch gas leakage detection are optimized, leakage point detection time is shortened, and leakage detection efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of power detection equipment, in particular to a method and system for detecting gas leakage of a power switch. Background technique [0002] Gas-insulated switchgear has the advantages of small size, light weight, good safety, high reliability, and adaptability to harsh environmental conditions, and is widely used in high-voltage and ultra-high-voltage fields. In actual operation, due to factors such as product manufacturing quality, operation loss and improper installation, gas leakage occurs. With the leakage of gas, the gas pressure in the equipment drops. When it is lower than a certain critical value, insulation breakdown will occur, causing the switchgear to burn out, and even affect the operation of the entire circuit network. Therefore, it is urgent to detect the gas leakage of the insulated switchgear in order to find and solve the leakage problem in time . [0003] At present, the most...
