如何避免混凝土搅拌车漏电?
来源:https://www.cnzkjf.com/ 日期:2020-07-17
  下面中科搅拌车带大家了解一下如何避免混凝土搅拌车漏电。
  Next, Zhongke mixer takes you to know how to avoid electric leakage of concrete mixer.
  1、区分线路是不是的确漏电。
  1. Distinguish whether the line is indeed leakage.
  可以在用兆欧表摇测线路绝缘电阻的大小,或许在总刀闸上接一个电流表,在不开设备的前提下,接通全部搅拌站设备,假如电流表指针摇摆,则标明线路漏电。
  Megohmmeter can be used to measure the insulation resistance of the line. Maybe an ammeter should be connected to the main switch. On the premise of not opening the equipment, all the equipment in the mixing plant can be connected. If the pointer of the ammeter swings, it will indicate the line leakage.
  2、区分是相线与零线间漏电仍是相线与大地间漏电,或二者兼而有之。
  2. The difference is between the phase line and the zero line, or between the phase line and the earth, or both.
  区分的办法是堵截零线,或电流表指示不变,则是相线与大地间漏电;
  The method of distinguishing is to block the zero line, or the ammeter indication remains unchanged, then the leakage between the phase line and the earth is;

  3、判定漏电规划。
  3. Determine the leakage planning.
  取下分路熔断器或摆开刀闸,若电流表指示不变,则是总线漏电;若电流表指示为零,则是分路漏电;若电流表指示变小但不为零,则标明总线、分路均漏电。
  Remove the shunt fuse or swing the switch. If the ammeter indication remains unchanged, it is the bus leakage; if the ammeter indication is zero, it is shunt leakage; if the ammeter indication becomes smaller but not zero, it indicates that both the bus and shunt are leaking.
  4、找出漏电点。
  4. Find out the leakage point.
  经上述查看后,再依次摆开该线路灯具的开关。当摆开某一开关时,若电流表指示返零,则是该分支线漏电,若电流表指示变小,则标明除该分支线漏电外,还有别处漏电。或许运用测电笔分段检验亦可。
  After the above inspection, turn on the switch of the line lamp in turn. When a switch is turned on, if the ammeter indication returns to zero, it is the branch wire leakage; if the ammeter indication becomes smaller, it indicates that in addition to the branch wire leakage, there are other leakage. Maybe we can use the electric pen to test the sections.
