【正文】 原因包括電器設備或導線過載、電器設備安裝或使用不當,而造成溫度升高至危險溫度,引起設備本身或周圍物體燃燒等,而由于短路引起的事故,達電氣火災事故的40%。漏電保護器的應用分析[摘 要]:漏電保護器是一種在用電設備上使用的安全保護裝置,它以漏電電壓為信號,包括試相部分,檢測部分和斷電訊響部分,其工作電壓為12伏,用于檢測用電設備的殼體電壓,一旦用電設備殼體電壓達到保安器工作電壓即動作,它不受用電設備容量,單相、三相的限制,使用面廣,互換性好,可確保用電設備和人身安全,亦可作為用電設備的絕緣監(jiān)視器使用。[關鍵詞]:漏電保護器 ,作用 ,局限性 ,等電位聯(lián)結 [Application Analysis of leakage protectionAbstract:Leakage protection device is a device for use in power protection device, it leakage voltage signals, including part of the test phase, testing part and the broken part of the telemunications ring, its operating voltage of 12 volts, used to detect the electrical equipment the shellvoltage, once the shellvoltage electrical equipment to achieve security device operating voltage that is action, it is not electrical equipment capacity, singlephase, threephase constraints, the use of a wide range, interchangeability, and can be to ensure that electrical equipment, and personal safety, also serves as the insulation monitor the use of electrical equipment.Key words: Leakage protection device, role, limitations, and other potential connection0 引言近年來,我國火災事故形勢嚴竣,就發(fā)生火災的原因分析,其中電氣火災占火災總數(shù)的25%~30%,占火災事故原因中首位。短路可分為相間短路和單相短路(接地短路),在對因電氣短路引起的
