Description

Technical Field

[0001] The utility model relates to the technical field of insulator hardware, in particular to an anti-dropping type insulator hardware. Background Art

[0002] Insulator hardware refers to the metal parts used on insulators. Hardware is a general term for all metal accessories used in high-voltage transmission and transformation lines, electrified railway contact networks and other systems; the application environment of insulator hardware determines the characteristics of insulators, namely stability, reliability and good safety performance.

[0003] Most insulator strings are connected by a ball-and-socket connection between a ball-head fitting and a bowl-head hanging plate and locked by a spring pin. This connection structure is suitable for vertical insulator strings or insulator strings with a small inclination angle. However, for suspended strings with "V"-shaped installation forms, due to the large inclination angle of the insulator string and the influence of the outdoor environment, the line is frequently disturbed by strong winds, and the conductor vibration causes the insulator string to twist and swing. After a period of operation, the ball-and-socket structure is strongly worn and the matching gap becomes larger. The spring locking pin gradually loses its original locking effect and becomes loose and falls off, causing the ball head (steel foot) of the insulator to fall out of the bowl head, causing serious accidents such as line drop and string drop, affecting the safe and stable operation of the power grid. Therefore, the utility model designs an anti-drop insulator fitting to solve the problems existing in the prior art. Utility Model Content
