漏电断路器与微动开关在自动停水控制系统中的应用

Application of Creepage Breaker and Microswitch in Automatic Suspension System

对目前市场上自动停水系统进行分析,存在以下几个问题.(1)控制系统容易出现问题,导致不能按要求停止上水,造成浪费和其它二次危害;(2)价格较高,农村的用户有的接受不了;(3)使用寿命较短、故障率较高,损坏后、维修麻烦.将漏电断路器与微动开关应用了自动停水控制系统避免了以上述问题的发生,还有助于开拓学生的思维,能把低压电器设备灵活应用.通过讲解实例制作,介绍了漏电断路器、微动开关及简单传动机构的巧妙组合,简单可靠地完成自动停水控制.

There are several problems in automatical water supply cutting-off system offered in present market. First, the control system is likely to have problems in stopping after the upstream request, and easy to cause waste and secondary harms; Second, the price is too higher for the countryside user to accept; Third, the service period is short with higher fault rate. The automatical water supply cuttingoff system introduced which can avoid the ＇above questions to make the low pressure electric appliance available. How to combine leakage circuit breaker, the microswiteh and the simple transmission system effectively to realize water supply cutting-off automatically based on cases are also introduced too.
