1 , post vacuum circuit breaker trolley intra alta voltage switchgear clausus est in positio experimentale, circuit trolley breaker non potest intrare positio operationis. (Avoid closing with load).
2,Quando culter terrantis intra alta voltage switchgear in loco clausus est, circuitus trolley fractor clausus non potest. (Avoid closing with grounding wire).
3, quando vacuum circuit breaker in alta voltage switchgear clausus est, culter mechanical grounding at the back door of the cabinet is used to lock the cabinet door. (Avoid accidentally entering the electrified distance)
High voltage switchgear refert to a device used for power generation, transmission, distribution, energy conversion, and consumption in the power system to perform functions such as switching, operation, or maintenance.
High voltage switchgear is classified into several types, including electrical products with voltage levels ranging from 3.6kV to 550kV, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage active reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear.
