2.三相(xiang)交(jiao)流空气(qi)开(kai)关的检(jian)查及检(jian)修(xiu)。检(jian)查三相(xiang)交(jiao)流空气(qi)开(kai)关手动(dong)脱(tuo)扣是(shi)(shi)否(fou)(fou)灵活。合上空气(qi)开(kai)关后(hou)，A、B、C三相(xiang)各(ge)相(xiang)接(jie)触电(dian)阻是(shi)(shi)否(fou)(fou)小于1Ω；脱(tuo)扣后(hou)，三相(xiang)各(ge)相(xiang)接(jie)触电(dian)阻是(shi)(shi)否(fou)(fou)大于1MΩ，否(fou)(fou)则(ze)应予(yu)更换。检(jian)查热继电(dian)器接(jie)点是(shi)(shi)否(fou)(fou)正(zheng)常，动(dong)作(zuo)电(dian)流设定(ding)值(zhi)是(shi)(shi)否(fou)(fou)正(zheng)确。

3.阀(fa)门电(dian)(dian)(dian)(dian)动装置(zhi)控制(zhi)(zhi)箱上(shang)电(dian)(dian)(dian)(dian)源检(jian)(jian)查。检(jian)(jian)查电(dian)(dian)(dian)(dian)动阀(fa)门A、B、C三(san)相电(dian)(dian)(dian)(dian)压，通电(dian)(dian)(dian)(dian)操(cao)作控制(zhi)(zhi)开关按钮(niu)，A、B、C三(san)相相间电(dian)(dian)(dian)(dian)压应(ying)为交(jiao)流380V左(zuo)右，否则，请运(yun)行(xing)人员检(jian)(jian)查380V交(jiao)流母(mu)线情况，确保电(dian)(dian)(dian)(dian)源正常(chang)配电(dian)(dian)(dian)(dian)箱上(shang)保险(xian)容量(liang)检(jian)(jian)查。

4.阀(fa)(fa)门(men)(men)(men)电动(dong)装置(zhi)控制箱上指(zhi)示(shi)(shi)灯(deng)(deng)检(jian)查及检(jian)修。阀(fa)(fa)门(men)(men)(men)电动(dong)装置(zhi)控制箱上指(zhi)示(shi)(shi)灯(deng)(deng)在(zai)(zai)通电后(hou)，应(ying)与现场阀(fa)(fa)门(men)(men)(men)位置(zhi)对应(ying)，阀(fa)(fa)门(men)(men)(men)全(quan)开(kai)时(shi)，红(hong)(hong)灯(deng)(deng)亮阀(fa)(fa)门(men)(men)(men)关严(yan)(yan)时(shi)，绿灯(deng)(deng)亮；在(zai)(zai)中间(jian)位置(zhi)时(shi)，红(hong)(hong)绿灯(deng)(deng)都亮。阀(fa)(fa)门(men)(men)(men)电动(dong)装置(zhi)控制箱通电后(hou)，按(an)(an)红(hong)(hong)色灯(deng)(deng)，阀(fa)(fa)门(men)(men)(men)应(ying)向(xiang)开(kai)方向(xiang)运(yun)动(dong)，直至(zhi)全(quan)开(kai)按(an)(an)绿色灯(deng)(deng)，阀(fa)(fa)门(men)(men)(men)应(ying)向(xiang)关方向(xiang)运(yun)动(dong)，直至(zhi)关严(yan)(yan)。有特殊(shu)要(yao)求的阀(fa)(fa)门(men)(men)(men)，无保(bao)持功(gong)能，可以点动(dong)开(kai)关至(zhi)任一(yi)位置(zhi)。

5.阀门电动(dong)装置控制箱上(shang)指示灯与上(shang)述现象(xiang)不一致时，检查电气(qi)控制回路与指示灯，直(zhi)至(zhi)合(he)乎要求。

6.阀门电动装(zhuang)置控(kong)(kong)制箱(xiang)(xiang)内(nei)、终端柜端子排检查及检修接线(xian)检查检查阀门电动装(zhuang)置控(kong)(kong)制箱(xiang)(xiang)内(nei)接线(xian)端子应紧固、整齐，线(xian)号编(bian)码清(qing)晰，各(ge)接线(xian)对地绝(jue)缘(yuan)、线(xian)间绝(jue)缘(yuan)应为(wei)∞值。
