異步電動(dòng)機智能綜合保護器
摘 要:本論文主要介紹異步電動(dòng)機的各種保護原理。通過(guò)對異步電動(dòng)機基本工作狀態(tài)的陳述說(shuō)明它的保護方向。有效的電動(dòng)機保護方法與設備，既能對電動(dòng)機可能出現的各種故障實(shí)施可靠的保護。又能充分發(fā)揮電動(dòng)機的過(guò)載能力，是減小生產(chǎn)過(guò)程中的經(jīng)濟損失，提高經(jīng)濟效益必需解決的問(wèn)題之一。
智能型異步電動(dòng)機綜合保護器應用P87LPC76XOTP單片機實(shí)現了智能化設計，電流檢測簡(jiǎn)單，參數整定方便，動(dòng)作穩定可靠，具備過(guò)載保護、空載節能多種功能，且與主電路連接簡(jiǎn)單方便。
關(guān)鍵詞:保護器；過(guò)載；空載；自整定。 Intelligence asynchronous motor protection devices integrated circuit
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
