  1. 有时断路器在使用时,用手摸上去温度有些高,很担心开关会跳,但电流又没有达到额定电流,怎么办?

    依据GB14048.2端子温度: 塑壳80K,微断60K。
    iC65在使用过程中,如果发热,是否属于正常? 
    根据国家标准GB10963规定,在规定条件下,断路器各部分的极限温升为:连接外部导体的接线端子应小于等于60度;在手动操作中会触及的外部应小于等于40度,断路器与安装平面直接接触的表面应小于等于60度
  2. 发现UPS输入麻豆AV在线免费观看的地线上有电流,是什么原因,关系大吗?

    有时发现在总麻豆AV在线免费观看内PE线上用钳表测得有几安培的电流,而UPS输入麻豆AV在线免费观看的PE线上钳得更大的电流。有以下几个原因:
    1、  设备接地不良,或接地线太小,电阻偏高所致;
    2、  设备通过外壳漏电
    3、  系统混接,就是用电设备的零线和地线混接,当三相不平衡越大则越严重。
    4、  有其他地方地线与本系统地线接在一起,而在此处再导入地桩。这种情况可断开本系统总开关,再测地线电流可知。
    5、  地线中有10A以下的电流基本不可怕,只要对地极桩没有电压即是安全的,也是正常的,因为有时会有干扰电流产生。
  3. 为什么低压一级麻豆AV在线免费观看设计时,两进一母联系统一般没有机械联锁装置?

    两进一母联的两个进线开关分别接至两台变压器,一般项目中两台变压器多数并排安装,导致麻豆AV在线免费观看分列配置,两个进线开关为面对面操作,有几米的跨度。如采用机械联锁缆绳,极不可靠。
  4. 现场经常见到一些PM待仪表的功率显示负值,有时电量也显示负值,是什么原因

    1、  电力仪表中常用的几个参数:有功功率、无功功率、有功电度、无功电度、功率因数等是带有方向性的,正常的显示正值,反方向的显示为负值,只是有些仪表会做一些处理,比如功率因数为负时,处理为“数值正,加上容性(-II-)符号”,看上去显示为正值。
    2、  当有功显示为负值时,肯定为以下原因:互感器穿心电流方向反(P2进、P1出),或互感器的极性反(S1与S2反接);
    3、  当无功显示为负值,而有功显示为正时,可以肯定负载为容性负载;
    4、  电度计量一般极少为负值,如果电流及互感器方向反,或接线错误最终一般导致的为计量不准,或不计量,不会为负值。如果出现值极有可能为容性负载。
    5、  如果仅功率为负数,而N线电流又为0,那么要么是显示为负数的相电压线互相接错。
  5. MT控制单元为何有的有显示,有的无显示?

    1、  如果电流降至0.2*In(In=额定电流)以下,数字显示消失。要保证在20%以上才能保证显示,20%以下有可能显示有可能不显示。
    2、  如果在0.2倍额定电流以下仍有显示,则此显示无意义。
    3、  控制单元的显示,只能是参考作用,控制单元主要是为MT提供各项保护。
    4、  对于现场有些会点亮有此不会点亮面板,是由于控制单元的电源是取自MT的后端,故只有合闸才会亮,或有电源进时会亮。
    5、  如果有外接电源,则一定会有显示。
  6. 由UA、BA等控制的ATS有故障报警时如何复位?

    1、  对于塑壳断路器,带有马达机构,用手拉动储能手柄一次即可复位。
    2、  对于MT等框架断路器,需要将断路器上的红色脱扣按钮复位,最好再将UA、BA上的转换开关转至停止位,再切换到自动位。
