Between connecting portion occur loosen, gap, cause operation when operational stroke diminish, can not divide-shut brake in place just stop, so as to cause
Switch can not normal work；（2）Operating mechanism bad sealing causes internal drive element lubricating grease to have dust, or time slightly long meeting
Lubricating grease is dry and astringent to provide lubrication for each element inside mechanism case, cause the bite that gets rusty, so as to influence by mechanism to switch
Timely divide-shut brake operation is carried out, very big potential safety hazard is caused to electrical network economy and life.
2nd, disconnecting switch conduction defect：（1）After conventional disconnecting switch operation a period of time, disconnecting switch divide-shut brake less than
Position causes that dynamic and static contact clamping force is inadequate, and contact resistance is bigger than normal, so as to cause switch to generate heat；（2）Longtime running opening out of doors
Close conducting position, after exposing to the weather the surface of conducting position easily be oxidized, the electric conductivity of switch is diminished, resistance increase from
And causing the conductive exothermal of switch, conductance reduces；（3）Conventional disconnecting switch conductive contact position is without automatical cleaning ability, easily quilt
Dust, oil pollution cause loose contact, the shunting of fingertip spring, are allowed to annealing and follow the string, and fingertip spring corrosion is followed the string,
Current-carrying part overheating fault；（4）The fault of construction of former junction block, cause poor in operating condition（High humidity, filthy weight, load
Weight）Transformer station's long-play after, disconnecting switch defect take place frequently bite, heating, corrosion the defects of, to Reliability of Power Supplying Net Work
Have a great influence.
