Background
The bolt that punches that present transmission line bolt adopted the R round pin, and the use purpose of R round pin is because of the disappearance of R round pin, and the bolt nut derotation drops and leads to the gold utensil to connect not hard up, causes the hidden danger for circuit safe operation. In the use process of the traditional R pin, after long-time abrasion, the R pin can be oxidized, rusted and shed. In recent years, defects such as drop and loss of the R pin account for more than seventy percent of defects of power transmission, most of the defects belong to major defects according to a defect grading standard, operation and maintenance personnel need to periodically perform R pin compensation work on line power failure, equipment is unnecessarily stopped, and a large amount of manpower and material resources are extremely wasted.
When the traditional R pin bolt is used, the R pin is a part manufactured by bending a flat wire rod into a ring, the R pin is inserted into an opening at the tail of the bolt, and then the tail of the R pin is forked and broken, so that the effect of preventing the nut from rotating and loosening is achieved. However, the R pin can be oxidized and rusted and fall off after being used for a long time, and after the blockage of the R pin is lost, the circuit is influenced by wind power to vibrate, so that the nut is loosened. At this time, the occurrence of such a situation brings inestimable consequences to the safe operation of the transmission line.
The other defect of lacking the R pin is that the strain clamp uses the cylindrical bolt, only the gasket and the R pin are used, once the R pin is lost, the strain clamp has a major defect in a defect grading standard, when the R pin is found to be lost, the strain clamp is required to be subjected to emergency power failure within 7 days for treatment, similar conditions frequently occur in operation and maintenance of the power transmission line, and huge risks are brought to safe operation of the power transmission line.
