Product

ZW32-12 outdoor column vacuum circuit breaker is a product developed by our company in response to the requirements of the State Grid primary and secondary fusion complete sets of column switches into the network, and the switch configuration meets the requirements of the State Grid primary and secondary integration complete sets, which is convenient for the unified procurement and mass production of the State Grid. The switch structure is compact, the layout is reasonable, the functions are complete, and all indicators meet the requirements of the primary and secondary integration of the State Grid; The protection CT, zero sequence CT and zero sequence voltage sensors with unified parameters have the characteristics of wide measurement range, high measurement accuracy and high reliability, and the analog quantity is complete to accurately determine various faults of the line.

ZW32SR-12 primary and secondary deep fusion complete sets of column circuit breaker adopts the principle of vacuum arc extinguishing, permanent magnet operating mechanism (elastic operation mechanism), and integrates microprocessing technology, modern network communication technology and switch manufacturing materials. Outdoor power distribution equipment with rated voltage of 12kV and 50Hz three-phase AC. The product is widely used as a disconnect or contact switch in the urban power grid, or in the rural power distribution system. The outgoing switch of outdoor substation can effectively complete the work of the traditional recloser, dividing and closing the load current and short-circuit current.

ZW32-12G primary and secondary fusion standardized column. The upper circuit breaker is a complete set of pole circuit breaker equipment that integrates the industry's electronic voltage sensor, current sensor, electric energy metering module, high-speed fault transient recording and other technologies according to the requirements of the State Grid standard "Typical Design of Primary and Secondary Complete Equipment for Power Distribution". The complete set of equipment can not rely on the distribution automation master station and communication, to achieve the function of "adaptive comprehensive local automation", through the short circuit/grounding fault detection technology, pressureless switching, fault path adaptive delay call closing and other control logic, adaptive multi-branch multi-contact distribution network frame structure, to achieve single-phase grounding fault local line selection, regional positioning and isolation, through two reclosers to achieve fault area isolatio

LW58-12KV outdoor column SF6 circuit breaker is our company's corresponding State Grid 10kV primary and secondary fusion complete set of column circuit breaker network new requirements and developed products, switch configuration fully meets the requirements of the State Grid primary and secondary fusion of complete sets, convenient for the State Grid unified procurement, mass production, compact switch structure, reasonable layout, complete functions, all indicators are in line with the State Grid primary and secondary integration requirements; The protection CT, zero-sequence CT and zero-sequence voltage sensors with unified parameters are adopted, which have the characteristics of wide measurement range, high measurement accuracy and high reliability, and the analog quantity is complete to facilitate the accurate determination of various faults of the line.
