HV Indoor Vacuum Circuit Breaker

The SanGao HV Indoor Vacuum Circuit Breaker adopts a solid insulation structure and utilizes advanced epoxy sealing technology to organically combine vacuum arc extinguishing chambers, main electrical circuits, insulation supports, and other components into an integrated sealed pole for the first time. Successfully solved the environmental tolerance problem of vacuum circuit breakers fundamentally, making their application more widespread.

The integrated solid sealed pole adopts self convection technology, cleverly solving the problem of heat dissipation caused by solid insulation structures The VBR (VS1) -12 series solid sealed indoor high-voltage vacuum circuit breaker is a circuit breaker that realizes the concept of maintenance free in China.

The application of its long life HV Indoor Vacuum Circuit Breaker arc extinguishing chamber and epoxy casting sealing technology ensures the maintenance free integration of the sealed pole, and the high reliability permanent magnet operating mechanism that can be used ensures the maintenance free operation of the operating mechanism. The electronic control part abandons the traditional auxiliary switch and replaces it with a photoelectric proximity switch, and adopts a fully electronic power supply and intelligent control unit to ensure the maintenance free operation of the electronic control part

The HV Indoor Vacuum Circuit Breaker is an indoor switchgear for three-phase AC 50Hz power systems with a rated voltage of 12kV. It serves as a protection and control unit for power grid equipment and power equipment in industrial and mining enterprises. Suitable for places that require frequent operation at rated working current, or multiple disconnections of short-circuit current.

The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.

The HV Indoor Vacuum Circuit Breaker is suitable for three-phase AC power systems with a rated voltage of 12KV and a frequency of 50Hz. It can be widely used in power plants, substations, petrochemicals, metallurgy, manufacturing airports, and residential areas as a control and protection device for electrical facilities. It is particularly suitable for places where frequent operation or multiple short-circuit currents are disconnected under rated current. It can be installed in indoor air insulated switchgear (such as KYN28 and KYN96) for supporting use. The circuit breaker complies with the requirements of GB1984 "High Voltage AC Circuit Breakers", JB Factory T3855 "High Voltage AC Vacuum Circuit Breakers", DL/T 403 "Technical Conditions for Ordering 12KV~40.5kV High Voltage Vacuum Circuit Breakers" standards, and meets the relevant requirements of standards such as IEC62271-100.
