The closed pin, commonly known as a spring pin, is a fastener of hardware fittings on a power transmission line, prevents a nut from withdrawing from a bolt through inserting a socket on the bolt, and plays a limiting role in the bolts of various hardware fittings.
According to the regulations of overhead transmission line operating regulations, the loss of the closed pin is a serious defect, and the closed pin is required to be repaired in time. Through statistical analysis, the loss of 110kV closed pins is more. The loss of the closed pin is more than serious defect, and if the closed pin of the wire clamp is lost, the closed pin is critical defect, so that accidents such as tripping and shutdown of a line caused by the fact that the power transmission line is disconnected can be caused.
