Three-Phase Automatic Circuit Recloser
Solidly embedded poles ensure insulation reliability. The permanent magnetic mechanism delivers fast and stable operation, while accurate fault identification and isolation comprehensively enhance the reliability of the distribution network.
Product Description
The HXD811 series three-phase reclosers include three models: HXD811-15, HXD811-27, and HXD811-38. A complete three-phase recloser system consists of primary equipment (the recloser switch) and secondary equipment (the recloser controller). Widely deployed in modern power grids, the three-phase recloser is primarily designed for fault identification, localization, and isolation, significantly enhancing the power supply reliability of distribution feeders.
While its applications are very similar to a pole-mounted circuit breaker paired with an FTU, the three-phase recloser sets itself apart with higher insulation performance requirements. Driven by a permanent magnetic mechanism, it features a simpler yet more reliable structure, offering faster response times and a longer mechanical lifespan. Furthermore, it provides richer protection functions and supports a broader range of communication protocols.
