Handling and Use of Sulfur Hexafluoride Gas

(4) Open gas compartment valve. b) Transfer Cart/cylinder: (1) Loosely connect hose to gas compartment valve. (2) Partially open the gas cylinder valve. (3) Check for presence of SF 6 gas in the vicinity of the connection to the gas compartment valve using an approved halogen leak detector. (4) Seal all fittings as soon as SF 6 gas is detected.

As discussed, in 220 kV, 400 kV and 765 kV applications, the gaz sf6 gas pressure is maintained at 6.5 bar. You will be amazed that, even though voltage level is increasing, same pressure of Sulfr hexafluoride i.e. 6.5 bar is used for 220, 400 and 765 kV applications. Actually as we go up at higher voltage level, the number of contacts increases in sf6 gas circuit

They utilized a compressor arrangement to pressurize the arc extinguishing sf6 gas to a pressure of gas to enable multiple operations of this style of circuit breaker. This high pressure sf 6 is released across the contacts by-way of a blast valve assembly, which is actuated during the mechanical operation of the breaker (either opening or closing).

Self-sealing valves and permanently gas-tight connections take care that no environmentally hazardous SF 6 gas escapes, but rather remains safely in its designated containers. The service operations, such as evacuation and filling of SF 6 tanks or the processing of SF 6 gas must be carried out with the appropriate equipment.
