中间继电器跳闸有什么解决办法?

  中间继电器在使用过程中难免会有一些问题出现,比如说跳闸现象的出现,这要如何进行解决呢?下面来讲几个方法。
  There will inevitably be some problems in the use of intermediate relay, such as trip phenomenon, how to solve it? So let's do a couple of things.
  查找剩余电流动作中间继电器自身故障。先切断电源,再将剩余电流动作中间继电器的零序互感器负荷侧引线全部拆除再合中间继电器。若中间继电器仍然无法投运,则说明中间继电器自身故障,应予以修理或更换。
  Find the fault of residual current action intermediate relay itself. First cut off the power supply, and then remove all the lead wires on the load side of the zero-sequence transformer of the remaining current action intermediate relay before closing the intermediate relay. If the intermediate relay still cannot be put into operation, it indicates that the intermediate relay itself is faulty and should be repaired or replaced.
  若能正常运行,则中间继电器本身并无故障,再查找配电盘或者线路。先将各路出线或交流接触器负荷切断,若不能运行则说明配电盘上有故障,应检查各路电气、仪表等设备是否绝缘良好,接线是否正确;若能正常运行则说明配电盘上无故障。当确认故障发生在外线路上时,可采用分线查找法查找故障点。
  If it works normally, there is no fault in the intermediate relay itself, and then look for the distribution board or line. First cut off each outlet line or ac contactor load, if it can not run, it means there is a fault on the distribution board, should check each electrical, instrument and other equipment is good insulation, wiring is correct; If it works normally, there is no fault on the distribution board. If a fault occurs on an external line, use the split line search method to locate the fault.
  直观巡查法就是巡视人员针对故障现象进行分析判断,对保护区域包括剩余电流动作中间继电器和被保护的线路设备等进行直观巡视,从而找出故障点。
  Intuitive inspection method is patrol personnel for fault phenomenon analysis and judgment, the protection area including residual current action intermediate relay and protected line equipment intuitive inspection, so as to find the fault point.
  ABB中间继电器价格人员认为巡视时应着重对线路的转角、分支、交叉跨越等复杂地段和故障易发点进行检查。这种方法简便易行,适用于对明显故障点的查找。如导线断线落地、拉线与导线接触及错误接线等。
  ABB intermediate relay price personnel believe that inspection should focus on the line corner, branch, crossing and other complex sections and fault prone points. This method is easy to use and is suitable for the search of obvious fault points. Such as wire broken ground, pull wire and wire contact and wrong wiring, etc.
  排查线路故障点时,断开低压电网的各条分支线路,仅对主干线进行试送电,若主干线无故障,那么主干线便能正常运行。然后,再依次将分支和末端投入运行。哪条线路投入运行时中间继电器跳闸,故障点就在哪条线路上,就可在此线路上集中查找故障点。
  When identifying the fault point of the line, disconnect each branch line of the low-voltage power grid, and only test the main line. If the main line has no fault, then the main line can run normally. The branches and ends are then put into operation. When the intermediate relay trips when the line is put into operation, the fault point is on the line, and the fault point can be searched centrally on this line.
