Vertical insulator ratchet fastener for 10 kV electric power overhead line, and application method

Abstract

The invention relates to a vertical insulator ratchet fastener for a 10 kV electric power overhead line, and an application method. The vertical insulator ratchet fastener comprises a first buckle clamp, a second buckle clamp, a spring, a lock catch, silica gel loops, a first pin and a second pin, wherein the first buckle clamp and the second buckle clamp are each internally provided with an arc structure, the silica gel loops are fixed on the inner walls of the arc structures, one end of the first buckle clamp and one end of the second buckle clamp are movably hinged to each other through the first pin, the other end of the first buckle clamp is movably hinged to the lock catch through the second pin, the other end of the second buckle clamp is provided with reverse ratchet teeth, and the lock catch is provided with forward ratchet teeth matching the second buckle clamp; the spring is arranged between the lock catch and the first buckle clamp for limiting the position of the lock catch; and the first buckle clamp and an insulator form an integrated structure. The vertical insulator ratchet fastener and the method have the following advantages: the operation of the ratchet fastener is simple and rapid, the work efficiency is improved, the high-altitude operation time of personnel is reduced, the operation safety coefficient is enhanced, and the fastening effect is better; and the ratchet fastener is large in structural strength, is corrosion-resistant and is not affected by such environment factors as wind power, air humidity and the like.

Description

technical field [0001] The invention relates to a vertical insulator ratchet for 10kV power overhead lines and a use method thereof. Background technique [0002] The traditional 10kV overhead conductors and insulators are fixed with insulating binding wires or pressure plate screws. The disadvantages of these methods are: [0003] 1. When fixing the overhead wires with the binding method of insulating wires, due to the limitation of the technical level of the construction personnel, the construction quality varies, and some insulation wires loosen under the action of the wind, causing the overhead wires to fall off from the insulators, resulting in Accidents such as 10kv system grounding or overhead line tripping affect the safe and stable operation of the system. [0004] 2. When using pressure plate screws to fix, the components of the pressure plate screws are prone to oxidation under the action of high humidity air such as rain and snow, which will cause the pressure p...
