Questions about sf6 Maintenance plants

Feb 20, 2021 · Maintenance of SF6 circuit breaker. A common problem with an SF6 circuit breaker is gas leakage. When leakage occurs, the gas pressure decreases. This reduces the quenching ability of the circuit breaker. To avoid this, always check your breakers often. You can check that via the pointer of the gas gauge.

  • MAINTENANCE OF SF6 GAS CIRCUIT BREAKERS

    SF6 is odorless, colorless,tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is reduced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks should be purged out after opening.
