VS1 (650mm)-type indoor AC HV vacuum circuit breaker is a hree-phase AC 50Hz, rated voltage of 7.2~ 12KV indoor high voltage switchgear. Circuit breaker in linewith our national standards GB/T1984"high voltage AC circuit breakers” ,JB3855 “3.6 ~ 40.5KV indoor AC HV vacuum circuit breaker” and the relevant IEC standard Accurate, and reliable interlock function. Circuit breaker operation can be frequent, with several breaking and fast reclosing function. Circuit designed around the packing structure, either as a fixed installation of the unit can also be equipped withthe car pretending to drive a single hand car use.

Physical dimension
Environmentally friendly gas-insulated metal enclosed switchgear is the most commonly used three-phase intelligent gas-insulated AC cabinet and is widely used in various switchgear sets, with population concentration in the country, the power market must be supported, environmentally friendly gas-insulated switchgear will also grow with market development; market potential is yet to be tapped. At the same time, as the product integrates data collection and management, data processing and storage, online monitoring of switchgear, advanced analysis, and other multifunctions in one, network intelligent monitoring and management of the distribution network, so that the distribution network operates in a safe, reliable, high-quality, and efficient best state, to achieve remote monitoring, management, and control of the power system distribution network, to achieve network optimization, safe electricity use, power management, energy saving, and consumption reduction; at the same time, the system can be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas, and commercial office buildings.
