vacuum switch

Function:

Automatically cut off single-phase grounding faults. When a single-phase grounding fault occurs in the user branch line, the boundary circuit breaker will automatically open, and other branch users on the substation and feeder line will not feel the occurrence of the fault. Automatic isolation of phase to phase short circuit faults. When a phase to phase short circuit fault occurs in the user branch line, the boundary circuit breaker trips before the substation outgoing line protection switch, automatically isolating the faulty line without affecting power outages in other branch users on the feeder line. Quickly locate the fault point. When the fault in the user's branch line causes the boundary circuit breaker protection to operate, only the responsible user will cut off the power, and they will actively report the fault information. The power company can quickly send personnel to the scene for investigation; If the boundary circuit breaker is equipped with a communication module, it will automatically report the information to the power management center. Monitoring user load, when the boundary circuit breaker can be configured with wired or wireless communication accessories, the monitoring data will be transmitted to the power management center to achieve remote real-time data monitoring of user load. Remote operation function, users can operate the vacuum boundary circuit breaker to open through a mobile app or computer backend.

ZW32-40.5 Outdoor Line Vacuum Circuit Breaker (Watchdog)It adopts vacuum arc extinguishing and SF6 gas as insulation medium, and the box adopts the gas sealing, explosion-proof, and insulation structure technology introduced from Toshiba VSP5 in Japan. The sealing performance of the incoming and outgoing line sleeves has also been improved, and the overall sealing performance is excellent. The SF6 gas filled inside does not leak and is not affected by the external environment; The spring operating mechanism has been designed for miniaturization and optimized for reliability and stability. It adopts a direct acting chain main transmission and a multi-stage trip system, which improves the reliability and stability of the action by several times compared to traditional spring operating mechanisms in China; The contact between the shaft and the sleeve of the main circuit adopts an inward and outward tension type watch chain structure, which has low contact resistance and low temperature rise in the main circuit.
