Vacuum contactor_Vacuum circuit breaker_Energy storage power station special isolation switch_Chennuo Electric Technology Group Co., Ltd

In line with the standard, the product performance has reached the advanced level, suitable for wind power, photovoltaic high-power inverter devices, cost-effective, replacing imported products, saving electricity, strong breaking ability, small bounce of closing and opening, stable performance, reasonable and beautiful structure, safe and reliable.

The switch itself is equipped with a grounding switch, which can effectively prevent misoperation such as "hanging ground wire with electricity and closing with ground wire", and the operator does not have to connect with another grounding wire. The switch can be flexibly configured with single-sided grounding, double-sided grounding, manual mechanism, electric mechanism, integrated installation arrester, the switch comes with mechanical locking to prevent misoperation, and can be equipped with electromagnetic locks to realize the interlocking between the main knife switch and the ground knife, the isolation switch and the circuit breaker, which is widely used in photovoltaic, wind power stations, substations, SVG static var generator supporting equipment.

It can monitor the voltage, current, reactive power and power factor of the high-voltage line in real time, and dynamically monitor and compensate the high-voltage power grid according to these parameters, which plays an important role in improving the power factor and voltage of the line, reducing the line loss and improving the power supply quality of the power grid.

It is fully equipped with positive and negative bus DC contactors and fuses, emergency stop protection switches, input lightning protectors, leakage switches, grounding and insulation detection and monitoring safety protection devices, and has multiple protection functions and logic in software and hardware. Provide stable, reliable, safe and secure electricity services for taxis, buses, logistics vehicles, online car-hailing, urban comprehensive, public transport groups, car rental companies, etc.

This system is mainly for the low-voltage power supply network aging electrical lines, electrical fires caused by line or equipment insulation failures caused by electrical fires and electric shock casualties and other accidents for effective prevention and protection.
