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 become almost the only 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.

The YTC4503A SF6 gas leak detector uses the wrapping method to measure the annual leakage rate of SF6 gas electrical equipment. At the same time, this equipment is widely used for detecting SF6 gas leaks in power supply bureaus, substations, high-voltage switchgear companies, laboratory safety fume hoods, scientific experiments, and other fields.
