質(zhì)優(yōu)價廉，值得您信賴！
電子式電動機保護器已由晶體管發(fā)展到集成電路至今已發(fā)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(jié)能、動作靈敏、度高、耐沖擊振動，重復(fù)性好、保護功能齊全、功耗小等優(yōu)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(zhuǎn)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(fā)生斷相、過載、短路、欠壓、過壓和漏電等故障時實現(xiàn)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(fù)，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(xiàn)計算機聯(lián)網(wǎng)。同時可監(jiān)控、監(jiān)測256臺電動機工作等功能。
