假如接地(di)电阻未超(chao)过或超(chao)出生产商提(ti)议的极小值(zhi),请(qing)运行(xing)下列流(liu)程(cheng):

流(liu)程1.保证电缆线的(de)导电性芯原材(cai)(cai)料(liao)(liao)未与(yu)金(jin)(jin)(jin)属(shu)材(cai)(cai)料(liao)(liao)接(jie)地装置编织(zhi)线或(huo)接(jie)线箱(xiang)的(de)其它金(jin)(jin)(jin)属(shu)材(cai)(cai)料(liao)(liao)构件触碰(peng)。查验(yan)(yan)所有的(de)开关电源联(lian)接(jie),连接(jie)头,三(san)通(tong)盒和(he)顶端(duan)密封性,以保证导电性芯板与(yu)全部(bu)金(jin)(jin)(jin)属(shu)材(cai)(cai)料(liao)(liao)零件(包含接(jie)地装置纺织(zhi)物(wu))防护。假(jia)如导电性芯触碰(peng)金(jin)(jin)(jin)属(shu)材(cai)(cai)料(liao)(liao),请做好需(xu)要的(de)检修并开展兆(zhao)欧表查验(yan)(yan),直至接(jie)地电阻超出厂(chang)家的(de)最(zui)低标准(zhun)规定。查验(yan)(yan)接(jie)线箱(xiang)和(he)端(duan)密封性时,请保障所有的(de)联(lian)接(jie)全是干躁的(de),由于湿(shi)的(de)接(jie)线箱(xiang)或(huo)端(duan)密封性会造(zao)成(cheng)兆(zhao)欧表检测不成(cheng)功。

流程2.假如未(wei)看到(dao)所(suo)有金(jin)(jin)属材料零(ling)件(jian)或(huo)纺织物与导电(dian)(dian)(dian)(dian)(dian)性(xing)芯(xin)触碰(peng),而且(qie)(qie)接(jie)地(di)(di)电(dian)(dian)(dian)(dian)(dian)阻依然过低,请(qing)(qing)防(fang)护电(dian)(dian)(dian)(dian)(dian)源电(dian)(dian)(dian)(dian)(dian)路上(shang)(shang)的(de)每根加热电(dian)(dian)(dian)(dian)(dian)缆,并(bing)各自开展(zhan)兆欧表查验。这能(neng)够(gou)(gou)协助明确(que)加热电(dian)(dian)(dian)(dian)(dian)缆的(de)物理学毁坏地(di)(di)区,该地(di)(di)区造成导电(dian)(dian)(dian)(dian)(dian)性(xing)铜(tong)芯(xin)电(dian)(dian)(dian)(dian)(dian)缆与管(guan)路上(shang)(shang)的(de)金(jin)(jin)属材料接(jie)地(di)(di)装置手(shou)工(gong)编织层短路故(gu)障。查验管(guan)路系统(tong)软件(jian),并(bing)在检测低的(de)一部(bu)分(fen)上(shang)(shang)找寻显著的(de)毁坏征兆。要(yao)是(shi)没有突出的(de)毁坏征兆,则最好是(shi)卸(xie)掉并(bing)拆换检测工(gong)作(zuo)电(dian)(dian)(dian)(dian)(dian)压较低的(de)那一部(bu)分(fen)电(dian)(dian)(dian)(dian)(dian)缆线(xian)。能(neng)够(gou)(gou)对(dui)更久的(de)部(bu)位开展(zhan)按段(duan)和检测,以防(fang)护常见故(gu)障。防(fang)护常见故(gu)障后(hou),请(qing)(qing)清除电(dian)(dian)(dian)(dian)(dian)缆线(xian)的(de)有什么问题一部(bu)分(fen),并(bing)且(qie)(qie)用新电(dian)(dian)(dian)(dian)(dian)缆线(xian)将(jiang)其(qi)拆换。

流程3.假如加热电缆一部分检测一切正常,则对从电缆线接线箱返回电伴热控制面板的电源插头开展另一次兆欧表查验。假如电源插头短路故障,请拆卸电源插头并拆换新线路。

电源电路溫度过低(di)

电源电路溫度也许太低,由于:

控(kong)温器或全过程控(kong)制板预设值(zhi)有误

温度控制器(qi)布线不正确

电(dian)缆线未接入开关电(dian)源

电缆(lan)线衔接到问题的(de)工作电压

温度感应器(qi)置放有误

温(wen)度(du)感应器布线不正确

电(dian)缆线(xian)总数不能相抵系统软件(jian)中的热管(guan)散热器。

请采用下列(lie)流程(cheng)明确超低温(wen)的直接原因。

流程(cheng)1.保(bao)证将控(kong)温器或全过(guo)程(cheng)自动控(kong)制系统(tong)设定为所需的(de)管路(lu)溫度。

流程(cheng)2.在做(zuo)到额定值(zhi)时,查验控温器的连接线(xian)是(shi)(shi)不是(shi)(shi)合闭(bi)。大部(bu)分(fen)控温器能(neng)够从(cong)公(gong)共(gong)性接线(xian)端子布线(xian)到开与关或(huo)常(chang)闭(bi)部(bu)位(wei)。查验用以控温维护运用的控温器是(shi)(shi)不是(shi)(shi)从(cong)公(gong)共(gong)性接线(xian)端子联接到常(chang)闭(bi)部(bu)位(wei)。

流程(cheng)3.再度查验线(xian)(xian)缆(lan)(lan)(lan)是(shi)不是(shi)已(yi)连接(jie)开关电(dian)(dian)(dian)源(yuan)(yuan)。在(zai)(zai)电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)开关电(dian)(dian)(dian)源(yuan)(yuan)接(jie)线(xian)(xian)箱和电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)顶端(duan)液压密封件(jian)中(zhong)检(jian)(jian)测开关电(dian)(dian)(dian)源(yuan)(yuan)。在(zai)(zai)电(dian)(dian)(dian)源(yuan)(yuan)电(dian)(dian)(dian)路尾端(duan)开展检(jian)(jian)测将保证加热(re)电(dian)(dian)(dian)缆(lan)(lan)(lan)在(zai)(zai)电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)的(de)所有(you)长短上(shang)面有(you)两根(gen)优良的(de)母(mu)线(xian)(xian)槽。每一个线(xian)(xian)路的(de)开始(shi)与结束处的(de)工作电(dian)(dian)(dian)压读(du)值应(ying)相对性(xing)类似。远距(ju)离(li)电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)会产生一些电(dian)(dian)(dian)流;降(jiang)低量因电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)种类和生产商而(er)异,因而(er)请查询机器设备的(de)表明文(wen)档。可是(shi),假(jia)如检(jian)(jian)测表明电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)逐渐时(shi)为120V,完毕时(shi)为0V,则最(zui)少一根(gen)电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)系(xi)统总线(xian)(xian)输电(dian)(dian)(dian)线(xian)(xian)损(sun)坏,因而(er)必须卸掉并拆换电(dian)(dian)(dian)缆(lan)(lan)(lan)线(xian)(xian)。

流程(cheng)4.保证电(dian)缆线衔(xian)接到准确(que)(que)的工(gong)作电(dian)压。查验(yan)工(gong)作电(dian)压时,将(jiang)精确(que)(que)测量值与制定文档开(kai)展(zhan)较为。比如(ru),以(yi)120V供电(dian)系统的240V电(dian)缆线将(jiang)难以(yi)保持合理的管路(lu)溫度(du)。开(kai)展(zhan)需要的调节以(yi)改正一切工(gong)作电(dian)压难题。
