Tension insulator string RTV spraying protective cover

Abstract

The invention provides a tension insulator string RTV spraying protective cover. The cover comprises a shielding cover, wherein hanging connecting devices are arranged at the two ends of the shieldingcover correspondingly; and each hanging connecting device comprises a mounting plate, the top of each mounting plate is fixedly connected with a first vertical rod, a hanging device is arranged on each first vertical rod, each hanging device comprises a second vertical rod, arc-shaped hooks are hinged to the two sides of the top of each second vertical rod correspondingly, and a horizontal positioning baffle is further arranged above the hinged position between each hook and the corresponding second vertical rod. The cover has the positive effects of being suitable for various types of insulator equipment, and having the remarkable generalization performance. The integral structure further has the advantages of being simple and compact in structure, light in weight, easy to carry, convenient to move and the like; and the consumed mounting time is short, and scissor fork arms on the two sides of each mounting plate meet the requirements for bearing capacity and the telescopic performance and are not prone to deform, so that the balance generated after the two sides are extended is strong, and more convenience is brought to aloft work.

Description

technical field [0001] The invention relates to the technical field of electrical equipment maintenance auxiliary appliances, in particular to a RTV spraying protection cover for tension string insulators. Background technique [0002] Pollution flashover refers to the pollution attached to the insulating surface of electrical equipment, under humid conditions, its soluble substances gradually dissolve in water, forming a conductive film on the insulating surface, greatly reducing the insulation level of the insulator, and appearing under the action of electric field force Strong discharge phenomenon affects the service life of electrical equipment and the safety of the power grid. The usual countermeasure is to spray RTV on it. After atomizing the liquid RTV silicone rubber coating, it is sprayed on the surface of electrical equipment. The current RTV spraying operation is widely used. The press drives a special spray gun for spraying. This construction method is easy to co...

[0002] Pollution flashover refers to the pollution attached to the insulating surface of electrical equipment, under humid conditions, its soluble substances gradually dissolve in water, forming a conductive film on the insulating surface, greatly reducing the insulation level of the insulator, and appearing under the action of electric field force Strong discharge phenomenon affects the service life of electrical equipment and the safety of the power grid. The usual countermeasure is to spray RTV on it. After atomizing the liquid RTV silicone rubber coating, it is sprayed on the surface of electrical equipment. The current RTV spraying operation is widely used. The press drives a special spray gun for spraying. This construction method is easy to control and easy to operate. However, there is no control measure for the atomized paint brought out by the high-pressure airflow, which makes the paint easy to float during the spraying process, which will not only damage the electrical equipment.
