HDV (VS1) -31.5 Indoor AC high-voltage vacuum circuit breaker adopts the integrated design of operating mechanism and circuit breaker body. It can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit. Suitable for three-phase AC 50Hz, rated voltage of 10kV power system for switching of various types of loads and frequent operation occasions, can be used for industrial and mining, enterprises, power plants and substation electrical equipment protection and control.
HDV28-40.5 vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear with three-phase AC 50HZ and rated voltage 40.5kV. The circuit breaker conforms to GB1984-1989 'AC High Voltage Circuit Breaker', JB3855-1996 '3.6-40.5kV Indoor AC High Voltage Vacuum Circuit Breaker' and IEC related standards. The circuit breaker can be used by industrial and mining enterprises, power plants and substations to divide the load current, overload current and fault current, and is suitable for places with frequent operations.
Microcomputer comprehensive protection device (hereinafter referred to as device) is an advanced microcomputer comprehensive protection device, which mainly protects feeders, factory transformers, motors and other equipment with voltage levels of 10KV and below. The installation depth of the device is only 130mm, which is especially suitable for places such as ring network cabinets that have high requirements for installation depth. The device can also be installed in high-voltage switch cabinets or panel installation.
