Prerequisites For Cleaning The Insulation Components Of The Operating Mechanism Of An Sf6 Circuit Breaker With Anhydrous Alcohol

Before cleaning the internal insulating components of sf6 circuit breaker operating mechanism, several prerequisites must be met to ensure that sf6 circuit breaker spring mechanism meets engineering specifications and safety requirements during the cleaning process.

Site Environment Requirements

The work site should be dry, well-ventilated, and free from significant sources of pollution. Humidity, moisture in the air, and dust can affect the cleaning effect of the insulation components and may introduce impurities into the circuit breaker.

Circuit Breaker Status and Gas Handling

The circuit breaker must be in the de-energized state, and the SF6 gas must have been vented and properly sealed according to the manufacturer's requirements. Disassembly and cleaning should not be performed if SF6 has not been removed or if it contains decomposition products.

Cleaning Tools and Alcohol Quality

The anhydrous alcohol used must be of industrial grade purity with extremely low water content. Use a clean, lint-free cloth or tissue paper dampened with a small amount of alcohol to wipe the surface of the insulation components, avoiding alcohol accumulation and residue as much as possible.
