252kV Gas-insulated Equipment Purpose
1.SF6 gas in the gas filled cabinet is used as arc extinguishing and insulation medium 2.The switch cabinet is a fully enclosed and fully insulated structure; the busbar and live parts of the switch machine are completely enclosed in the stainless steel shell;
This method is extremely sensitive and the limit of detection for the CFCs are 0.005 x10 12 moles per kilogram of water (pmol kg 1). The limit of detection for SF6 is even more sensitive at 0.05 x 10 15 moles per kilogram of water (fmol kg 1). Precision values for all three CFCs are 2 % or less. SF6 precision is 5% or less.

66KV CIRCUIT BREAKER gas Leak factory
Maximum gas leakage rates are typically specified as being not greater than 1% per annum in order to ensure adequate gas retention within the anticipated maintenance periods of the circuit breaker. Low gas density alarms are usually fitted to give indication of loss of gas and, in the event of rapid loss of gas, circuit breaker immediate tripping or trip lockout systems are usually employed.
