제품 세부 정보
Used to control and monitor the density of SF6 gas in sealed containers. This series of density relays are mainly used to monitor the density of SF6 gas in sealed containers. They can be widely used in SF6 circuit breakers, ring network cabinets, gas charging cabinets, pole switches, transformers and mutual inductors. They are suitable for harsh outdoor conditions. In response to gas leakage in SF6 electrical equipment, they can promptly send out alarm signals, locking signals and overvoltage alarm signals to ensure the safe operation of SF6 electrical equipment.
