Embodiment Construction

[0026] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limit the claims of the present invention.

[0027] The first object of the present invention is to provide an anti-mis-closure interlocking structure. The structural design of the anti-mis-closure interlocking structure can effectively solve the need for continuous debugging when using the anti-mis-closure interlocking structure, which is time-consuming and laborious and has poor reliability. The second object of the present invention is to provide a vacuum circuit breaker including the above-mentioned anti-mis-close interlocking structure.

[0028] The schemes in the embodiments of the present invention will be clearly and completely described below in conjunction with the a...

Abstract

The invention discloses a false switching-on prevention interlocking structure, which comprises a switching-on half shaft (1), a second gear (10) and a driving device, wherein a one-way bearing (11) is sleeved at the other end of the switching-on half shaft (1); a first gear (12) is sleeved outside the one-way bearing (11); the second gear (10) can be meshed with the first gear (12) through movement; and the driving device drives the second gear (10) to move. By structural design of the false switching-on prevention interlocking structure, the problems of waste of time and labor for continuous debugging of the false switching-on prevention interlocking structure and low reliability can be effectively solved. The invention also discloses a vacuum circuit breaker which comprises the false switching-on prevention interlocking structure.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, in particular to an interlocking structure for preventing mis-closing, and also relates to a vacuum circuit breaker with the interlocking structure for preventing mis-closing. Background technique [0002] Vacuum circuit breakers are circuit breakers that use vacuum as the insulation and arc-extinguishing medium between contacts. Because of their small size and light weight, they are widely used in distribution networks. Many industrial and mining enterprises, power plants, and substations are Use vacuum circuit breakers for protection and control of electrical equipment. [0003] When working or experimenting with a vacuum circuit breaker, it is generally necessary to move the position of the vacuum circuit breaker. At present, a chassis vehicle is generally used to move the position of the vacuum circuit breaker. However, during the moving process, if the vacuum circuit bre...
