電動機綜合保護(hu)器采用先進的微機技術(shu)與高性能(neng)的集成芯片(pian)，整機功能(neng)強大、性能(neng)優越。測試精度(du)高，線(xian)性度(du)好，分辨率(lv)高，整機抗干擾(rao)能(neng)力強，保護(hu)動作(zuo)可靠。三(san)相電流值，電壓值及(ji)各類(lei)故障(zhang)代號(hao)，顯示于LED、LCD上、直觀(guan)清晰。穩定性好，長期(qi)工(gong)作(zuo)無(wu)須維護(hu)。

　　電動機綜合保護器作用

　　電動機保(bao)護器的(de)作用是(shi)給電機全面(mian)的(de)保(bao)護，在電機出(chu)現(xian)過流(liu)、欠(qian)流(liu)、斷(duan)相、堵轉、短路、過壓(ya)、欠(qian)壓(ya)、漏電、三相不平衡、過熱、軸承磨損、定轉子偏心(xin)時，予以報警或保(bao)護的(de)裝置。

　　電機綜合保護器接法及原理

　　電(dian)(dian)(dian)動(dong)(dong)機(ji)保護(hu)器(qi)由三相電(dian)(dian)(dian)流互感器(qi)、檢(jian)測(ce)、放(fang)(fang)大(da)、延(yan)時、調整電(dian)(dian)(dian)路和執(zhi)行繼(ji)電(dian)(dian)(dian)器(qi)組成。檢(jian)測(ce)電(dian)(dian)(dian)路檢(jian)測(ce)到(dao)電(dian)(dian)(dian)流互感器(qi)感應的(de)電(dian)(dian)(dian)流缺相或大(da)于設(she)定值(zhi)時，經放(fang)(fang)大(da)器(qi)放(fang)(fang)大(da)，使(shi)繼(ji)電(dian)(dian)(dian)器(qi)動(dong)(dong)作(zuo)(zuo)。繼(ji)電(dian)(dian)(dian)器(qi)觸頭串接(jie)于接(jie)觸器(qi)線(xian)圈(quan)供電(dian)(dian)(dian)回(hui)路中，繼(ji)電(dian)(dian)(dian)器(qi)動(dong)(dong)作(zuo)(zuo)后使(shi)接(jie)觸器(qi)斷(duan)電(dian)(dian)(dian)，起到(dao)保護(hu)電(dian)(dian)(dian)機(ji)作(zuo)(zuo)用(yong)。延(yan)時電(dian)(dian)(dian)路用(yong)于避開(kai)電(dian)(dian)(dian)機(ji)起動(dong)(dong)電(dian)(dian)(dian)流，其時長可調。調整電(dian)(dian)(dian)路用(yong)于根據被(bei)保護(hu)電(dian)(dian)(dian)機(ji)工作(zuo)(zuo)電(dian)(dian)(dian)流精確設(she)置動(dong)(dong)作(zuo)(zuo)電(dian)(dian)(dian)流。

　　電機綜合保護器怎么調

　　有(you)兩個電(dian)(dian)位(wei)器，一個是調節電(dian)(dian)流，一個是調動(dong)作(zuo)時(shi)間，先(xian)把(ba)時(shi)間調長(chang)一點再(zai)，啟動(dong)電(dian)(dian)機，把(ba)電(dian)(dian)流調到過載指示不亮的時(shi)候(hou)就行了，再(zai)把(ba)時(shi)間調成你想(xiang)調定的值就可以。

　　步驟：

　　1、過電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)保護設定(ding)方法：把(ba)(ba)面板上的撥(bo)動開關(guan)撥(bo)至設定(ding)位置，調整(zheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)調節電(dian)(dian)(dian)(dian)(dian)位器(qi)使電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)顯(xian)示(shi)器(qi)數字(zi)為(wei)該(gai)電(dian)(dian)(dian)(dian)(dian)動機的額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值，再把(ba)(ba)開關(guan)撥(bo)到(dao)運行位置，此時(shi)顯(xian)示(shi)器(qi)上的數字(zi)為(wei)該(gai)電(dian)(dian)(dian)(dian)(dian)動機的工作電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。

　　2、啟動(dong)延時設(she)(she)定方法：全壓啟動(dong)可調至最小，總之啟動(dong)延時時間要根(gen)據用(yong)戶設(she)(she)備需要自行調整。

　　3、復(fu)位方法(fa)：當(dang)電機發生(sheng)故障(zhang)跳閘后，故障(zhang)指示燈亮(liang)，保護裝置處于記(ji)憶狀(zhuang)態，按下面板上復(fu)位健方可復(fu)。
