High-voltage Vacuum Circuit Breaker Product Introduction
Product Introduction High Voltage Vacuum Circuit Breaker Product Introduction
The high-voltage vacuum circuit breaker adopts a solid insulation structure and utilizes advanced epoxy sealing technology to organically combine the vacuum interrupter, main conductive circuit, and insulation support into an integrated solid-sealed pole for the first time. This successfully solves the environmental tolerance problem of high-voltage vacuum circuit breakers, making their applications more widespread. The integrated solid-sealed pole employs a patented self-convection ventilation technology, cleverly solving the heat dissipation problem caused by the solid insulation structure.
The high-voltage vacuum circuit breaker is the first circuit breaker in China to achieve the concept of maintenance-free operation. Its long-life vacuum interrupter and epoxy casting sealing technology ensure the maintenance-free operation of the integrated solid-sealed pole. It can also be equipped with a high-reliability permanent magnet operating mechanism to ensure the maintenance-free operation of the operating mechanism. The electronic control section abandons the traditional auxiliary switch in place 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 section.
