Product Description
The high-speed vacuum circuit breaker with magnetic drive and synchronized zero-cross switching is a key new generation switchgear that combines magnetic technology, synchronized zero-cross switching technology and vacuum arc suppression. The product combines the stability and reliability of traditional switches with the precision and efficiency of smart devices. The product is designed to solve key problems in electrical power systems, including reactive power compensation and rapid fault shutdown. Widely used in distribution networks with voltages up to 10 kV, in internal power supply systems of industrial enterprises, as well as in smart substations. Effectively eliminates the problems of traditional switches such as high current surges when turned on, strong harmonic interference and slow response to faults, ensuring stable and safe operation of networks and reliable power supply to enterprises.
Design Features
◆ Significant increase in electrical life: contacts are practically not subject to erosion, electrical life is 5–10 times higher than that of traditional switches.
◆ Significant reduction in mechanical failures: low control energy consumption, reduced shock loading, reduced wear of mechanical components, extended service intervals.
◆ Increased breaking capacity: switching off at the optimal time increases the reliability of switching off large short-circuit currents.
◆ Environmentally friendly: Reducing the use of greenhouse gases such as SF₆ is consistent with the “dual carbon” strategy.
◆ High level of intelligence: integration of measurement, control and communication functions, support for remote monitoring and predictive maintenance.
