summary

A complete set of equipment for a new type of primary and secondary fusion (pillar type) outdoor column mounted vacuum circuit breaker, used for the segmentation and connection functions of 10kV distribution network backbone lines. It integrates industry electronic voltage sensors, electronic current sensors, and energy metering modules (electromagnetic voltage transformers and electromagnetic current transformers can also be selected), calculates active and reactive power, power factor, frequency, and energy functions; Advanced technologies such as 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 network distribution network structure, it can achieve on-site line selection, regional positioning, and isolation of single-phase ground faults, It is a product of distribution automation that achieves fault area isolation and non fault area power recovery through two reclosures

Main functions

A complete set of new primary and secondary fusion (pillar type) outdoor column mounted vacuum circuit breaker equipment, used for the segmentation and connection functions of 10kV distribution network main lines; Adopting a fully sealed and insulated design, the circuit breaker body and the three remote feeder terminals are treated with spray molding to meet the anti condensation requirements; All aviation connectors are equipped with military grade accessories, and cables and aviation connectors are fully sealed, providing extremely high protection levels; Capable of calculating active and reactive power, power factor, frequency, and electrical energy; Equipped with adaptive comprehensive local feeder automation function.
