External Powered Vacuum Circuit Breaker

Our External Powered Vacuum Circuit Breaker is an external power-taking vacuum circuit breaker specially designed for outdoor pole-mounted distribution scenarios, which fundamentally solves the industry pain point of lacking auxiliary operating power in remote lines. This External Powered Vacuum Circuit Breaker adopts an external inductive power-taking device, which can induce and obtain working power directly from the high-voltage line itself, without additional laying of control cables and supporting power facilities. It greatly reduces project construction costs and construction difficulty, and is especially suitable for areas with imperfect power supply infrastructure such as mountainous areas and field regions. As a mature product of the external power-taking solution, the External Powered Vacuum Circuit Breaker integrates a reliable power management and energy storage module, which can stably output control power when the line is energized. It also has power-off energy storage function, and can complete opening and closing operations even during temporary line power outages, ensuring the continuity and reliability of distribution protection functions.

In terms of core performance and environmental adaptability, this external powered vacuum circuit breaker adopts vacuum arc extinguishing technology. The interrupter has high vacuum degree and strong arc extinguishing capability, with no open flame and no explosion risk during breaking, delivering excellent safety performance. Equipped with a permanent magnet operating mechanism, the equipment features fast action speed, high mechanical reliability and short opening/closing time, which can quickly isolate faulty lines and prevent fault expansion. The enclosure is integrally molded with high-strength epoxy resin, with strong weather resistance, corrosion protection and UV resistance, and can operate normally in a wide temperature range. Combined with years of application experience in outdoor distribution equipment, we have carried out multiple optimizations and upgrades on the power-taking efficiency, operation stability and anti-interference ability of this product, ensuring stable power taking and reliable action under different load conditions and meteorological environments, and providing overseas purchasers and end customers with a cost-effective passive distribution protection solution.
