Handling Of White Powdery Decomposition Products During Disassembly Of Sf6 Circuit Breaker Operating Mechanism

During the dismantling of sf6 circuit breaker operating mechanism, the white powdery decomposition material inside the container must be collected and buried deeply in a sealed container. This process originates from the decomposition of SF6 gas inside the equipment under conditions of electric arc, overheating, or localized breakdown, forming solid metallic fluorides, which exist as a white or light brown powder.

These powdery substances are irritating or corrosive and may further generate secondary byproducts such as HF and SO₂ upon contact with air, moisture, or metallic materials.

This step is crucial because if the container for sf6 circuit breaker spring mechanism is opened, the powder may disperse and adhere to the internal structure of the equipment or to the surface of people, potentially causing localized corrosion, mechanical jamming, and even skin irritation or respiratory discomfort.
