How to use laser imaging technology to locate and detect gas leaks in SF6 equipment?

Generally, the gas leak detection in SF6 equipment requires equipment outage maintenance, and the use of laser imaging technology to detect the gas leak of SF6 equipment does not require equipment outage, and the gas leak point of SF6 equipment can be accurately located at a distance without direct contact with the leak point. The change degree of gas content inside SF6 equipment was detected by laser imaging technology, and the internal insulation status of SF6 equipment was analyzed and studied.

At present, there are nearly 10,000 SF6 circuit breakers in operation in the power system, and more and more gas insulated metal enclosed combined electrical equipment (GIS) are put into operation. SF6 gas is the main substance to ensure the internal insulation in SF6 circuit breakers and GIS, and it is a very important work to ensure the safe operation of SF6 equipment.

Laser imaging detection is mainly the use of laser emission system, laser cooling system, low-light current acceptance system, signal conversion amplification and processing system, display unit, etc., because SF6 gas has a strong absorption of infrared light waves, so it can quickly detect very small leakage at a distance
