質優價廉,值得您信賴!
電子式電動機保護器已由晶體管發展到集成電路至今已發展到微處理芯片厚模電路,從功能上一般分為斷相保護、綜合保護(多功能保護)、溫度保護和智能保護。此類保護器具有節能、動作靈敏、度高、耐沖擊振動,重復性好、保護功能齊全、功耗小等優點。
1.電動機保護器(電機保護器)是以檢測線電流的變化(包括采取、正序、負序、零序和過流)為原則,可檢測斷相或過載信號。除具有斷相保護功能外,還具有過負荷、堵轉保護功能。
2.智能保護:集保護、遙測、通訊、遙控與一體的電動機保護裝置,對電動機發生斷相、過載、短路、欠壓、過壓和漏電等故障時實現保護,還具有電流電壓顯示,時間控制,軟件自診斷,來電自恢復,自啟動順序,故障記憶,自瑣和遠傳報警,顯示故障時的電流、電壓故障前后用代號閃爍示警,配置RS485通訊接口,實現計算機聯網。同時可監控、監測256臺電動機工作等功能。
