Product Overview
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 isolation and non-fault area to restore power supply, is a distribution automation product!
The primary and secondary fusion complete sets of circuit breaker equipment are used for the segmentation and liaison functions of the backbone line of the 10kV distribution network; Fully sealed and fully insulated design, the circuit breaker body and the terminal of the three remote feeders are sprayed with plastic to meet the requirements of anti-condensation; All aviation connectors are made of military-grade accessories, and cables and aviation plugs are fully sealed, with protection level; It has the function of calculating active power, reactive power, power factor, frequency and electrical energy; It has an adaptive, comprehensive in-situ feeder automation function. The new primary and secondary fusion complete circuit breaker equipment has a set of high-precision and wide-range voltage sensors to collect three-phase voltage and zero-sequence voltage to meet the measurement and metering functions of feeder terminals (FTU). The column circuit breaker has a set of high-precision current sensors that collect three-phase current and zero-sequence current to provide current signals for measurement, protection and metering functions.
ZW32-12G primary and secondary fusion standardized column circuit breaker (hereinafter referred to as circuit breaker) is an outdoor high-voltage distribution switchgear with a rated voltage of 12kV and three-phase AC 50Hz. The circuit breaker is mainly used to break and close the load current, overload current and short-circuit current in the power system, and is suitable for the protection and control of substations and industrial and mining enterprise distribution systems, as well as the places where the rural power grid needs to be operated frequently.
The circuit breaker conforms to GB/T 1984-2014 "High Voltage AC Circuit Breaker" DL/T 402- 2007 "Technical Conditions for High Voltage AC Circuit Breaker Ordering" and DL/T 403- -2000 "12kV~40.5kV High Voltage Vacuum Circuit Breaker Order Technical Conditions" and other technical standards.
