With the gradual improvement of voltage levels in domestic substations, the use of SF6 high-voltage circuit breakers in the power sector is currently growing at a rate of about 15% per year. In the fields of high voltage, ultra-high voltage, and ultra-high voltage switches, SF6 gas has almost become the insulation and arc extinguishing medium. However, SF6 high-voltage switches are mostly installed indoors, and the air flow is relatively slow. Once SF6 gas leaks, it is easy to cause local oxygen deficiency, causing workers to suffocate due to oxygen deficiency, posing a great safety hazard to their lives. Due to the decrease in insulation level, it also greatly reduces the arc extinguishing effect of high-voltage circuit breakers, causing damage to the circuit breaker body. Therefore, once SF6 gas leakage is discovered, corresponding measures must be taken to accurately locate the leakage point, repair the leakage point, and promptly eliminate the safety hazards of high-voltage circuit breakers.

There are various SF6 equipment in the market, and their production processes and equipment applications are also uneven. This has brought certain difficulties to power workers and the power industry in the application and maintenance of SF6 equipment during installation, operation, and maintenance. It not only reduces work efficiency, but also affects the quality of construction and maintenance, and may even cause leakage and lead to faults, which has a certain impact on the safe operation of the power system.

At this point, a good SF6 gas leak detector is needed to assist power workers in detecting leaks in equipment and containers filled with sulfur hexafluoride (SF6) or other halogen gases such as fluorine, chlorine, bromine, iodine, 1211, chloroform, Freon F11, F12, F13, F22, etc. It can quickly and accurately perform qualitative and quantitative testing.

The GDWG-III portable SF6 gas quantitative leak detector from? HV HIPOT Electric Co., Ltd. is widely used for detecting SF6 gas leaks in various fields such as power supply bureaus, substations, high-voltage switchgear companies, laboratory safety fume hoods, and scientific experiments. This instrument is a high-precision, high-sensitivity leak detector that uses non dispersive infrared (NDIR) technology to locate and quantify leaks. Mainly used for leak detection of GIS and SF6 gas filled equipment in the power industry. It can perform qualitative and quantitative testing on SF6 gas electrical equipment. Measure the annual leakage rate of SF6 gas electrical equipment using the wrapping method.
