中間繼電器在使用過程中難免會有一些問題出現,比如說跳閘現象的出現,這要如何進行解決呢?下面來講幾個方法。
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.
查找剩余電流動作中間繼電器自身故障。先切斷電源,再將剩余電流動作中間繼電器的零序互感器負荷側引線全部拆除再合中間繼電器。若中間繼電器仍然無法投運,則說明中間繼電器自身故障,應予以修理或更換。
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.
若能正常運行,則中間繼電器本身并無故障,再查找配電盤或者線路。先將各路出線或交流接觸器負荷切斷,若不能運行則說明配電盤上有故障,應檢查各路電氣、儀表等設備是否絕緣良好,接線是否正確;若能正常運行則說明配電盤上無故障。當確認故障發生在外線路上時,可采用分線查找法查找故障點。
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.

直觀巡查法就是巡視人員針對故障現象進行分析判斷,對保護區域包括剩余電流動作中間繼電器和被保護的線路設備等進行直觀巡視,從而找出故障點。
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中間繼電器價格人員認為巡視時應著重對線路的轉角、分支、交叉跨越等復雜地段和故障易發點進行檢查。這種方法簡便易行,適用于對明顯故障點的查找。如導線斷線落地、拉線與導線接觸及錯誤接線等。
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.
排查線路故障點時,斷開低壓電網的各條分支線路,僅對主干線進行試送電,若主干線無故障,那么主干線便能正常運行。然后,再依次將分支和末端投入運行。哪條線路投入運行時中間繼電器跳閘,故障點就在哪條線路上,就可在此線路上集中查找故障點。
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.
What is the solution to intermediate relay trip? The above is a few solutions, if you have other aspects of the method can come to the website www.xzthjc.com to share with us.
