Sign special for air switch

Abstract

The invention discloses a sign special for an air switch. The sign includes an upper clamp part, a lower clamp part and a spring for connecting the upper clamp part and the lower clamp part. The upperclamp part includes an upper clamp head and an upper clamp tail; an anti-skid rubber pad is arranged on the contact surface of the upper clamp head and the air switch, public signs are arranged on the outer surface of the upper clamp head, the lower clamp part includes a lower clamp head, a lower clamp tail and an anti-switch-off baffle, an anti-skid rubber pad is arranged on the contact surfaceof the lower clamp head and the air switch, and the anti-switch-off baffle is arranged on the inner side of the lower clamp head and at the position of an operation handle corresponding to the air switch for fixing the operation handle so that the air switch can be prevented from being switched off. The sign can solve the problem that it is difficult for the air switch to hang the sign and the indication directions of markers are not clear, and the sign has the advantages that the occurrence of electric power safety accidents is avoided to a large extent, hidden safety hazards caused by humanmisunderstanding are eliminated, disassembly is easy, the sign is convenient to use, and the application range is wide.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of signboards, in particular to a special signboard for air switches. Background technique [0002] Arrangement of safety measures is the key link of electric power safety. According to the requirements of relevant safety regulations of electric power enterprises, it is often necessary to hang the signboard of "no closing, man is working" on the operating handle of the air switch in the control box, terminal box, protective screen, etc. . [0003] At present, the signs used in substations are bound with nylon ropes, and then hung on the operating handle of the air switch. However, in the actual application process, there are the following problems: [0004] 1. The nylon rope is long, and the direction of the signboard is not clear after drooping, which is easy for the staff to misunderstand; [0005] 2. The operating handle of the air switch is very short, it is difficult to hang ...

AI Technical Summary

Problems solved by technology

[0004] 1. The nylon rope is long, and the direction of the signboard is not clear after drooping, which is easy for the staff to misunderstand;

[0005] 2. The operating handle of the air switch is very short, it is difficult to hang directly on the operating handle of the air switch, and it is easy to fall off;

[0006] 3. For the convenience of hanging, when the signboard is hung on the corresponding wire above the air, it is easy to cause the terminal to become loose, and there is also the problem of unclear direction. At the same time, it does not comply with the relevant regulations on electric safety, which may easily lead to electric safety accidents. , there is a greater security risk
