Insulator

Abstract

The invention relates to an insulator which comprises a core rod, a shed, a wire clamping device and a locking device, wherein the core rod is sleeved with the shed, the wire clamping device is installed at the upper end of the core rod, and the locking device is installed at the lower end of the core rod. The insulator can solve the problems that when a traditional pin insulator is installed, simple bolts and nuts are usually used for locking connection with a cross arm, the high-altitude operation wind power is large, the size of the nuts is small, the nuts are difficult to tighten tightly during locking, and the nuts are prone to loosening, so that a cable falls off to cause single-phase grounding, inter-phase short circuit is caused in severe cases, the occurrence rate and the maintenance rate of power accidents are increased, the stability and the reliability of a line are reduced, most traditional pin type insulators need to be added with a corresponding number of insulators for connection of a single cable and multiple groups of cables, the load on a cross arm is increased, the situation that the cross arm and the telegraph pole fall off due to the fact that the load is too heavy, and potential safety hazards are caused.

Description

technical field [0001] The invention relates to the field of insulators, in particular to an insulator. Background technique [0002] An insulator is a device installed between conductors at different potentials or between conductors and grounding components that can withstand voltage and mechanical stress. There are many types of insulators and different shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulating parts and connecting fittings. Insulators have good insulation performance, high mechanical strength, long service life, and strong resistance to climate change. With the advantages of flexible assembly and convenient operation and maintenance, it is widely used in lines of various voltage levels. [0003] Among them, the pin insulator is a kind of insulator, and the power pin insulator is widely used in the power system. [0004] 1. When installing traditional pin insulators, simpl...

AI Technical Summary

Problems solved by technology

[0004] 1. When installing traditional pin insulators, simple bolts and nuts are usually used to lock and connect the cross arm. Due to the strong wind force of high-altitude operations and the small size of the nuts, it is difficult to tighten them firmly when locking, and the nuts are prone to loosening If the situation is not good enough, the cable will fall off and cause single-phase grounding, and in severe cases, it will cause a phase-to-phase short circuit, which will increase the incidence of power accidents and maintenance rates, and reduce the stability and reliability of the line;

[0005] Most of the traditional pin-type insulators are for a single cable. The connection of multiple sets of cables requires a corresponding number of insulators, which increases the load on the cross-arm. Overload may cause the cross-arm to fall off from the pole, thus caused a safety hazard
