Product Overview

The primary and secondary fusion column mounted SF6 circuit breaker equipment is a column mounted circuit breaker equipment developed by Australia American Electric in accordance with the new standard "Typical Design of Distribution Primary and Secondary Complete Equipment" of State Grid Corporation of China. It integrates advanced technologies such as industry electronic voltage sensors, electronic current sensors, energy metering modules, and high-speed fault transient recording. This complete set of equipment can achieve "adaptive comprehensive local automation" function without relying on the distribution automation master station and communication. Through control logic such as short circuit/ground fault detection technology, voltage free opening, fault path adaptive delayed incoming and outgoing closing, and adaptive multi branch and multi contact distribution network structure, it can achieve on-site line selection, regional positioning, and isolation of single-phase ground faults, The product of distribution automation is to achieve isolation of fault areas and restoration of power supply in non fault areas through two reclosures.
