Summary
  ZW32-12F outdoor AC high voltage vacuum junction breaker (hereinafter referred to as the boundary breaker) is a new type of product independently developed by our company. The boundary breaker is a vacuum breaker, a boundary breaker and a sectional switch. The multi-functional intelligent device product is mainly composed of three parts: the vacuum boundary breaker body, the watchdog controller, and the external voltage transformer (Note: optional double-sided PT in the distribution network automatic ring network). It is widely used as a segmentation switch in the overhead ring network of 10kV urban and rural distribution network. It is an automatic switch device that can implement the load distribution of the ring network. It can be used as a demarcation switch in the branch line of large users. Door dog), feeder overhead power distribution network for the use of demarcation breaker sectionalizer, vacuum demarcation circuit breaker has remote management mode, protection control function and communication function. It can reliably judge and detect milliamp-level zero-sequence current and phase-to-phase short-circuit fault current in the boundary, and realize automatic cut-off single-phase ground fault and phase-to-phase short-circuit fault.
1、断路器采用三相支柱式结构,具有开断性能稳定可靠、无燃烧和爆炸危险、免维修、体积小、重量轻和使寿命长等特点。
2、断路器采用全封闭结构,密封性能好,有助于提高防潮、防凝露性能,特别适用于严寒或潮湿地区使用。
3、三相支柱及电流互感器采用进口户外环氧树脂固体绝缘,或采用户内环氧树脂外包有机硅橡胶固体绝缘;具有耐高低温、耐紫外线、耐老化等特点。
4、操动机构采用小型化弹簧操动机构,储能电机功率小,分合闸能耗低;机构传动采用真动传输方式,零部件数量小,可靠性高。操动机构置于密封的机构箱内,解决了操动机构锈蚀的问题,提高了机构的可靠性。
5、断路器的分、合闸操作可采用手动或电动操作及远方遥控操作。可与智能控制器配套实现配电自动化,也可以与重合控制器配合组成自动重合器、分段器。
6、断路器可以装设二相或三相电流互感器,供过电流或短路保护用,也可以给智能控制器提供电流采集信号;根据用户要求可加装计量用电流互感器。
7、断路器可外带三相联动的隔离开关,在隔离开关分闸状态下有明显可见断口,并具备与断路器本体之间的防误联锁装置,只有在隔离刀完全合闸或完全分闸时才可操作断路器。可连装避雷器支柱绝缘子,维护方便。
1. The circuit breaker adopts three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no burning and explosion hazard, maintenance-free, small size, light weight and long service life.
2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture and anti-condensation performance, and is especially suitable for use in cold or wet areas.
3, three-phase props and current transformers use imported outdoor epoxy solid insulation, or use the user's epoxy resin outsourcing silicone rubber solid insulation; with high temperature resistance, UV resistance, aging resistance and so on.
4. The operating mechanism adopts a miniaturized spring operating mechanism, the energy of the energy storage motor is small, and the energy consumption of the closing and closing is low; the mechanism transmission adopts the real motion transmission mode, the number of parts is small, and the reliability is high. The operating mechanism is placed in the sealed mechanism box, which solves the problem of corrosion of the operating mechanism and improves the reliability of the mechanism.
5. The circuit breaker can be divided or closed by manual or electric operation and remote remote operation. It can be integrated with intelligent controller to realize distribution automation, and can also be combined with coincidence controller to form automatic recloser and segmenter.
6. The circuit breaker can be equipped with two-phase or three-phase current transformers for overcurrent or short-circuit protection. It can also provide current acquisition signals to the intelligent controller. It can be equipped with current transformers for measurement according to user requirements.
7. The circuit breaker can be equipped with an isolating switch with three-phase linkage. When the isolation switch is opened, there is obvious visible fracture, and there is an anti-misoperation interlocking device with the main body of the circuit breaker. Only when the isolation knife is completely closed or completely The circuit breaker can only be operated when opening. It can be installed with lightning arrester post insulators for easy maintenance.
