Abstract

测电笔,包括装在笔杆中串联的固定检测头1、火线指示灯4、火线降压电阻3和人体触点5,笔杆2上联接有可折叠的零线检测笔6,零线检测笔6内装有串联的活动检测头9,零线降压电阻8和零线指示灯7,零线指示灯末端与火线降压电阻末端相联,特点是其外型与功能和传统测电笔一样,但可检测零线的通断。

Description

测电笔
本实用新型涉及到一种测电笔,属于测量电变量的电压存在的装置类。
传统测电笔,一般只能检测被测体是否带电,而不能检测零线的好坏,但日常生活中因零线断开而造成用电故障或事故的现象却屡见不鲜。
本实用新型的目的是提供一种可测量零线通断的测电笔。
本实用新型的目的是以下述方式实现的,即在传统测电笔的笔杆上联接有可折叠的零线检测笔。
本实用新型的特点是其外型与功能和传统测电笔一样,但可检测零线的通断。
本实用新型的附图1是其结构示意图,图2是其电原理图,图中编号为固定检测头1、笔杆2、火线降压电阻3、火线指示灯4、人体触点5、零线检测笔6、零线指示灯7、零线降压电阻8、活动检测头9。
下面结合附图说明本实用新型的实施例,参见附图,本实用新型包括装在笔杆2中串联的固定检测头1、火线指示灯4、火线降压电阻3和人体触点5,笔杆2上联接有可折叠的零线检测笔6,零线检测笔6内装有串联的活动检测头、零线降压电阻8和零线指示灯7,零线指示灯7末端与火线降压电阻3末端相联。当要测量零线时,可扳开零线检测笔6,将固定检测头1接触火线、活动检测头9接触零线,零线指示灯7亮即零线完好,而零线指示灯7不亮则表示零线为开路。将零线检测笔6扳到靠拢笔杆2即可作普通电笔用。
