ZW32-12F type of outdoor AC high voltage vacuum circuit breaker (hereinafter referred to as the boundary demarcation circuit breaker) is my company developed a new product, the boundary breaker is a set of vacuum circuit breaker, circuit breaker, sectionalizers boundary four open intelligent multi function device on one of the main products, configured by the vacuum demarcation circuit breaker body, the watchdog controller, an external voltage transformer (Note: distribution automation line ring network in bilateral PT optional three parts), the products are widely used in automatic switching device of 10kV City, rural power grid space ring circuit as piecewise isolating switch contact switch, can be implemented ring distribution line load, the branch line users the power supply can be used as cut-off switch (commonly known as the watchdog), overhead distribution network feeder for dividing circuit breakers sectionalizer for vacuum circuit breaker with remote demarcation, management mode, protection control function and communication function. Reliable judgment and detection limits of milliamperes zero sequence current and the phase to phase short circuit fault current and can automatically remove single-phase grounding fault and phase to phase short circuit fault.
The installation instructions for use provisions of the demarcation circuit breaker of the reference standard, the use of environmental conditions, type and rated parameters, structure features, working principle, order notes, and the operation, installation, use, maintenance method and content. 二、分界断路器的功能 Function of dividing circuit breaker
自动切除单相接地故障，当用户支线发生单相接地故障时，分界断路器自动分闸，变电站及馈线上的其它分支用户感受不到故障的发生。自动隔离相间短路故障，当用户支线发生相间短路故障时，分界断路器先于变电站出线保护开关跳闸，自动隔离故障线路，不会波及馈线上的其它分支用户停电。 快速定位故障点，当用户支线故障造成分界断路器保护动作后，仅责任用户停电，由其主动报送故障信息，电力公司可迅速派员到场排查；分界断路器如配有通信模块，则 动将信息报送到电力管理中心。监控用户负荷，当分界断路器可配置有线或无线通信附件，将监测数据传送到电力管理中心，实现对用户负荷的远方实时数据监控。远方操作功能，用户可以通过手机短信或计算机后台方式操作真空分界断路器分闸。
Automatic single phase to earth fault, when the user side of a single phase to ground fault occurs, the cut-off circuit breaker automatically gate, substation and other branches on the feeder can not feel the occurrence of failure. Automatic isolation fault phase, when the inter phase short circuit fault occurs in the user branch and demarcation circuit breaker before substation outlet protection tripping of the circuit breaker, automatic isolation fault line, will not spread to the feeder of the other branches of power users. Locate the fault point quickly, when the failure of the subscriber line of demarcation circuit breaker protection action caused by the, only responsibility power users, the initiative to submit fault information, power companies can be quickly sent to the scene investigation; demarcation circuit breaker if equipped with communication module, dynamic report the information to the power control center. Monitor user load, when the interface circuit breaker can be configured wired or wireless communication accessories, the monitoring data is transmitted to the power management center to realize the remote real-time data monitoring of user load. Remote operation function, the user can operate the vacuum demarcation circuit breaker through the mobile phone short message or the computer background mode.
