浙江恒控电气有限公司 Zhejiang Hengkong Electric Co. Ltd. 概 述 Almost ZW32-12F 型户外交流高压真空分界断路器（以下简称分界断路器）是我公司自主研发的一 款新型产品，分界断路器是集真空断路器、分界断路器、分段器四大开关于 一体的多功能智能化装置产品，主要配置由真空分界断路器本体、看门狗控制器、外置电压互感器 （注：配网自动化环网线路中可选双侧PT）三大部分组成，产品广泛用于10kV 城市、农村配电网架空环网线路中作分段隔离开关 联络开关、可实行环网线路负荷调配的 自动化开关装置，在大用户供电的分支线路中可作为分界开关（俗称看门狗），馈线架空配电 网络作分界断路器分段器之用，真空分界断路器具有远程管理模式，保护控制功能及通讯 功能。能可靠判断、检测界内毫安级零序电流及相间短路故障电流，实现自动切除单相接地 故障和相间短路故障。 本安装使用说明书规定了分界断路器的引用标准、使用环境条件、型号和额定参数、结 构特点、工作原理、订货须知、以及操作、安装、使用、维护的方法等内容。 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 not
