ZW32-12 Outdoor Pole-Mounted Vacuum Circuit Breaker

The primary and secondary fusion complete sets of column circuit breakers (deep integration pillar type) meet the standardized design scheme of the "No. 151" document of the Equipment Department of the State Grid Corporation, which is mainly composed of vacuum circuit breakers (deep integration pillar type), feeder terminals, power supply voltage transformers and aviation plug-in connection cables. The circuit breaker adopts an integrated sealed pole, the pole has a built-in vacuum interrupter and a digital transformer, and the ADMU module and feeder terminal adopt a hood structure. The overall design of the product meets the standardized design requirements of the State Grid, and the configured transformer has the characteristics of wide measurement range, high measurement accuracy and high reliability, which is convenient for the complete set of primary and secondary fusion devices to accurately determine various faults of the line. It is suitable for feeders, contact points, segmentation points, branches or user demarcation points of 10KV overhead distribution lines, and plays the role of breaking, controlling, protecting and line loss collection in the line.
