Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and specifically to a fastening device for post insulators. Background Art

[0002] A post insulator is an insulating device used to support and fix the conductive part of electrical equipment. It usually consists of an insulating part and a metal accessory. The insulating part generally uses electroceramics, glass, or organic composite materials, etc., which have good insulation performance and mechanical strength. The metal accessory is used for connection and fixation, playing a dual role of support and insulation in the power system. It can isolate the live conductor from the grounding body or live conductors of different phases, ensuring the normal operation of electrical equipment and the safety of personnel. It is widely used in substations, transmission lines, etc., such as bus support and disconnector support in substations;

[0003] The patent application with the publication number CN218568542U discloses a fastening device for post insulators, including an insulating cover, an insulating sleeve, an inner screw, a fastening sleeve, and an insulating handle. The insulating sleeve is fixedly connected to one end of the insulating cover away from the open end. The inner screw is coaxially installed in the insulating sleeve. The fastening sleeve is fixedly arranged at one end of the inner screw close to the insulating cover, and the insulating handle is fixedly arranged at the end of the inner screw away from the fastening sleeve. First, put the insulating cover on the outside of the post insulator until the open end abuts against the conductor of the post insulator, and then rotate the insulating handle. The insulating handle drives the inner screw to rotate relative to the insulating sleeve, and the inner screw drives the fastening sleeve to approach the fastening nut of the post insulator. When the fastening sleeve covers the fastening nut, continue to rotate the insulating handle, and the inner screw tightens the fastening nut through the fastening sleeve;

[0004] When tightening the above-mentioned patent, there is no need to hold the insulating cover by hand. The insulating handle has good insulation performance, and it can realize tightening the post insulator without power outage. However, when tightening the post insulator, under the conditions of strong wind and collision, the insulator will become loose, affecting the tightening effect of the insulator.
