Embodiment Construction

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the implementation manners in this application, all other implementation manners obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0070] It should be noted that when a component is referred to as being "disposed on" another component, it can be directly on the other component or a central component may also exist. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein...

Abstract

The present invention provides an umbrella cover and an electrical device applying the same. The umbrella cover is arranged on an electrical device including at least two insulators; the umbrella cover is provided with at least two installation holes configured to allow the at least two insulators to pass through and openings corresponding to the installation holes, and the openings communicate the installation holes and the edge of the umbrella cover. In one embodiment, the electrical device also comprises a housing, the at least two insulators are connected with the housing through housing connection portions; and the umbrella cover at least shield the housing connection portions. The effect of creep distance increasing of the umbrella cover is remarkable, and snow and rain and sewage can be effectively blocked, and the umbrella cover and the electrical device applying same have a good anti-pollution flashover effect. In one embodiment, the umbrella cover can effectively prevent snow and rain and sewage from entering the connection position of the connection portions with the insulators and the housing so as to improve the safety of the electrical device. The diameter of the umbrella cover is big to cut off the conductive channel configured to form an umbrella curtain so as to avoid even put an end to rain flashover accidents to some extent.

Description

Technical field [0001] This application relates to the field of power transmission equipment, and in particular to an umbrella cover and electrical equipment using the umbrella cover. Background technique [0002] The description in this section only provides background information related to the disclosure of this application, and does not constitute prior art. [0003] Certain open electrical equipment operating in an atmospheric environment, such as dry-type current transformers, circuit breakers, etc., are usually equipped with at least two parallel insulators. As the pollution level of the atmospheric environment increases, the use of the above-mentioned technology to insulate electrical equipment is not only affected by the high voltage of the operation, but also must consider the impact of the operating environment of the electrical equipment. Specifically, when environmental contaminants are deposited on the surface of the insulator, these environmental contaminants are so...
