According to the circuit breaker
, according to the circuit breaker installation method is divided into moving type (handcart type) and fixed type (1) moving type or handcart type (represented by Y): it means that the main electrical components in the cabinet (such as: circuit breaker) are installed on the handcart that can be pulled out, DBX meter box, because the handcart cabinet has good interchangeability, so it can greatly improve the reliability of power supply, Shanghai DBX meter box, commonly used handcart types are: isolation handcart, metering handcart, Circuit breaker handcart, PT handcart, capacitor handcart and used variable handcart, etc., Taizhou DBX meter box, such as KYN28A-12. (2) Fixed type (denoted by G): It means that all electrical components in the cabinet (such as circuit breakers or load switches, etc.) are installed fixedly, and the fixed switchgear is relatively simple and economical, such as XGN2-10, GG-1A, etc.
