ZW32-12F outdoor AC high-voltage boundary vacuum circuit breaker (commonly known as watchdog, hereinafter referred to as boundary circuit breaker) is an intelligent new product independently improved by Zhejiang Chuanlong Electric Co., Ltd. Zhejiang Chuanlong Electric produces watchdog series vacuum circuit breakers, such as models ZW32-12, ZW20-12, ZW8-12F. ZWHF-12, ZW43-12F, ZW7-40.5, ZW32-40.5, ZW10, etc. Chuanlong Electric's watchdog boundary circuit breaker has single-phase grounding protection, zero sequence protection, quick break overcurrent protection, and reclosing function. The feeder overhead distribution network is used as a boundary circuit breaker sectionalizer, and the vacuum boundary circuit breaker has remote management mode, protection control function, and communication function. It can reliably determine and detect milliampere level zero sequence current and phase to phase short-circuit fault current within the boundary, and automatically cut off single-phase grounding faults and phase to phase short-circuit faults.

Functional purpose

The boundary circuit breaker is a multifunctional intelligent device product that integrates vacuum circuit breakers, boundary circuit breakers, and sectionalizers. It is mainly composed of three parts: the vacuum boundary circuit breaker body, FDR type controller, and external voltage transformer (note: dual side PT can be selected in the distribution network automation ring network). The product is used as a section isolation switch interconnection switch in 10kV urban and rural distribution network air ring network lines, and can be used as an automatic switch device for load allocation of ring network lines. It can be used as a boundary switch (commonly known as a watchdog) in branch lines supplied by large users. The feeder overhead distribution network is used as a boundary circuit breaker sectionalizer. The vacuum boundary circuit breaker has remote management mode, protection control function, and communication function. It can reliably determine and detect milliampere level zero sequence current and phase to phase short-circuit fault current within the boundary, and automatically cut off single-phase grounding faults and phase to phase short-circuit faults.This ZW32 boundary circuit breaker installation and use manual specifies the reference standards, operating environmental conditions, model and rated parameters, structural characteristics, working principles, ordering instructions, as well as operation, installation, use, and maintenance of the boundary circuit breaker.

Product featuresThe intelligent boundary circuit breaker controller is mainly used in conjunction with the boundary circuit breaker, installed at the responsibility boundary point of the overhead distribution line, to protect the branch lines, automatically cut off single-phase grounding faults and phase to phase short circuit faults of the line, and ensure the electrical safety of non faulty users.The intelligent boundary circuit breaker controller is a cylindrical structure with good windproof, moisture-proof, dust-proof, earthquake resistant, and anti condensation functions; Ultra wide working temperature, reliable operation in an environment of -40~80 ℃; Using a 16 bit high-speed microcontroller as the main control chip, with 12 bit AD precision sampling, fast calculation speed, and protection function; All settings are continuously adjusted through a fully Chinese LCD, which is intuitive and clear; The controller and switch body are connected through control cables and aviation connectors, making installation convenient; *The wireless communication function allows users to remotely check the status of switches and control their opening and closing. This product is suitable for the control and protection of 10kV~35KV overhead distribution lines in urban and rural areas, and is an ideal device for supporting intelligent switch circuit breakers.
