The post insulator is a special insulating control and can play an important role in an overhead transmission line. The early-year post insulator is mostly used for telegraph poles, and one end of a high-voltage wire connecting tower which is gradually developed is hung with a plurality of suspended insulators, so that the insulator is used for increasing creepage distance and is usually made of silica gel or ceramics, namely the insulator. The insulator plays two basic roles in an overhead transmission line, namely supporting a wire and preventing current from flowing back to the ground, and the two roles must be ensured, the insulator cannot generate flashover breakdown caused by change of environmental and electrical load conditions to fail, otherwise, the insulator can lose the function and the service life of the whole line can be damaged.
The post porcelain insulator is an important part in power transmission and transformation system engineering, and is usually used after a plurality of post porcelain insulators are connected in series. In order to facilitate the serial connection between the insulators, flanges are respectively fixed at the upper end and the lower end of the insulator. When in series connection, the lower flange of the upper insulator is aligned with the upper flange of the lower insulator, and the mounting holes on the flanges are mutually corresponding and then fastened and connected. In order to improve the fastening between the flanges, a fastening glue is usually applied to the abutting surfaces of the two flanges. When the insulator after being connected in series needs to be disassembled due to maintenance and other needed reasons, the fastening piece needs to be loosened, and the fastening glue layer needs to be removed, so that the flanges are separated. The glue removing process is time-consuming and labor-consuming, so that the labor intensity is increased, the flange and the insulator can be damaged due to carelessness, waste is caused, and the use cost is increased.
