Abstract

本实用新型涉及一种漏电报警插座,是在现有的 插座或组合插座上装有漏电报警回路,插座的正面设 一指示灯孔和发音孔,以便人们及时地发现家用电器 漏电,避免用电事故的发生。本实用新型成本低廉, 安装方便,是现有普通插座或组合插座的理想换代产 品。

Description

本实用新型涉及一种插座,特别是能检测用电设备表面壳体漏电的报警插座。
现有的单相三脚插座,为家用电器接通电源的普通插接件,按用电规程规定,接壳体的第三脚必须接地才能保证安全。由于施工安装人员怕麻烦而普遍违反建筑设计要求,将应接地的第三脚空着不接,家用电器一旦漏电,不能及时发现,造成用户触电伤亡事故发生。即使第三脚按要求接地,家用电器漏电后,会使保险铅丝熔断,一时查不清原因,给电工及用户带来不便。
本实用新型就是针对现有普通插座不能对漏电报警的缺点,提供一种能及时报警家用电器壳体漏电的插座。
本实用新型是在普通插座或组合插座的背面在地线插脚和零线插脚之间接有一报警回路,漏电电流在地线插脚端进入该回路,经分压电容分压,全波整流二极管整流,滤波电容滤波,经稳压后,供给9561片及发光二极管发光,经9561变音频后供给压电片发声。并在该插座或组合插座的正面各设一指示灯孔和一发音孔。
本实用新型优点是,用电器漏电时,报警插座及时报警,提示用电人员注意安全,不爆总电源保险,便于维修人员查找故障,解决了一般三脚插座在电器漏电的情况下,爆保险和逐个电器查明原因的麻烦。
以下结合附图对本实用新型做详细的描述。
图1为本实用新型电气原理图。
图2为本实用新型插座正面示意图。
图3为本实用新型组合插座正面示意图。
图4为本实用新型左视图。
图1中,报警回路(8)接在地线插脚(1)与零线插脚(3)之间,当用电器壳体漏电时,漏电电流从地线插脚(1)进入报警回路(8),经分压电容C1分压。再经全波整流二极管D1、D2全波整流,并经滤波电容C2滤波,及稳压二极管WD稳压,得到稳定的直流电压供给9561片及发光二极管LED,经9561变音频后启动压电片YD发声,在图2及图3中,插座(6)及组合插座(7)正面皆开有发音孔(4)和指示灯孔(5),在图4中,压电片YD及发光二极管LED分别安装在插座(6)或组合插座(7)背面相应于发音孔(4)及指示灯孔(5)的位置上。
家用电器电源插头反插时,在地线插脚(1)与相线插脚(2)之间构成报警回路(8)。

Claims (1)
