異步電動機智能綜合保護器
摘 要:本論文主要介紹異步電動機的各種保護原理。透過對異步電動機基本工作狀態的陳述說明它的保護方向。有效的電動機保護方法與設備，既能對電動機可能出現的各種故障實施可靠的.保護。又能充分發揮電動機的過載能力，是減小生產過程中的經濟損失，提高經濟效益必需解決的問題之一。
智能型異步電動機綜合保護器應用P87LPC76XOTP單片機實現了智能化設計，電流檢測簡單，參數整定方便，動作穩定可靠，具備過載保護、空載節能多種功能，且與主電路連接簡單方便。
關鍵詞:保護器；過載；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
