Analysis Of Gas Micro-water Decomposition In Sf6 Circuit Breaker Operating Mechanism

Changes in Gas Composition of SF6 Circuit Breaker Operating Mechanism

During the operation of the SF6 circuit breaker operating mechanism, the phenomenon of micro-water decomposition in the gas can affect insulation performance. Trace amounts of moisture gradually decompose in SF6 gas, forming slightly acidic substances that may alter the gas's chemical properties.

• Chemical Reaction Process: The small amount of hydrogen fluoride generated from micro-water decomposition may come into contact with metal components in the operating mechanism, leading to minor corrosion.

• Gas Monitoring: Regular analysis of SF6 gas humidity and decomposition product content can provide a reference for the internal condition of the operating mechanism.

Operating mechanism maintenance and inspection

Monitoring of micro-water decomposition in device sf6 circuit breaker operating mechanism should be combined with data from gas density and humidity sensors. Operating mechanism operation records show that the rate of micro-water decomposition varies with temperature and gas pressure. Systematic analysis of the sf6 circuit breaker spring mechanism gas composition can reveal the micro-water decomposition trend, providing data support for subsequent maintenance.
