異步電動(dòng)機(jī)智能綜合保護(hù)器
摘 要:本論文主要介紹異步電動(dòng)機(jī)的各種保護(hù)原理。通過對(duì)異步電動(dòng)機(jī)基本工作狀態(tài)的陳述說明它的保護(hù)方向。有效的電動(dòng)機(jī)保護(hù)方法與設(shè)備，既能對(duì)電動(dòng)機(jī)可能出現(xiàn)的各種故障實(shí)施可靠的保護(hù)。又能充分發(fā)揮電動(dòng)機(jī)的過載能力，是減小生產(chǎn)過程中的經(jīng)濟(jì)損失，提高經(jīng)濟(jì)效益必需解決的問題之一。
智能型異步電動(dòng)機(jī)綜合保護(hù)器應(yīng)用P87LPC76XOTP單片機(jī)實(shí)現(xiàn)了智能化設(shè)計(jì)，電流檢測簡單，參數(shù)整定方便，動(dòng)作穩(wěn)定可靠，具備過載保護(hù)、空載節(jié)能多種功能，且與主電路連接簡單方便。

Abstract: Present paper main introduction asynchronous motor each kind of protection principle. Through explaining its protection direction to the asynchronous motor basic active status statement. Effective electric motor protection method and equipment, Can’t only implementate to each kind of breakdown reliable protection which possibly appears to the electric motor. But also can fully display the electric motor the overload capacity, Which reduces the economic loss in the production process, Enhance one of economic efficiency essential solution questions.
The intelligence asynchronous motor synthesis protector using the P87LPC76XOTP monolithic realized the intellectualized design, the electric current examination is simple, the parameter installation was convenient, movement stable reliable, had the over-load protection, idling energy conservation many kinds of functions, also with main circuit connection simple convenient.
Keywords: protector, overload, idling, self regulating
