QK485型程控断路器的工作原理及其研制

Work Principle and the Development of QK485 Program-Controlled Circuit Breaker Switch

QK 485型程控断路器的提出是基于目前用电负荷检测管理工作中实现欠费掉电的管理需求,可以利用现有已投运的计量设备,在办公室远程送电和停电;同时,还可以满足在不改变电能表用电信息采集系统的情况下,为家庭用户和工业用户供电,满足用户的基本需求。在对断路器作为用电系统的漏电保护装置进行了调查研究后,阐述了QK 485程控断路器的工作原理及研制过程中的技术要点。

QK485-type program-controlled circuit breaker made are based on cun＇ent electricity load testing in the management of arrearsto achieve power-down management needs, we can use existing measuring equipment which has been put into operation, in the office and remote transmission power; also meet the in the electricity meter does not change the case of information acquisition system for home users and industrial users to power supply, and meet the basic needs of the users. After the program-controlled circuit breaker as a leakage breakerprotection device was investigated in the electricity system, it describs work principles and development process of technical points in QK485 program-controlled circuit breaker.
