Chapter 2 Function Overview

With the gradual improvement of voltage levels in domestic substations, the use of SF6 high-voltage circuit breakers in the power sector is currently increasing at a rate of about 15/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 safety hazard to their lives. At the same time, it also reduces the degree of arc extinguishing effect of high-voltage circuit breakers and causes 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 high-precision handheld SF6 gas leak detector accurately searches for SF6 gas leakage points and quantitatively detects the leakage amount and annual leakage rate of SF6 circuit breakers and GIS through various methods such as detecting SF6 gas concentration values, providing sound and light alarms based on user set concentration thresholds, and detecting data trend charts. It brings convenience to halogen equipment maintenance.
