Problems solved by technology

[0002] The anti-misoperation locking device can prevent safety accidents and ensure the personal safety of the staff. The size of the anti-misoperation locking devices of circuit breakers or air switches on the market is uniform. The number of circuit breakers or air switches in different occasions cannot be determined, which makes the circuit breaker The application of the anti-misoperation locking device of the switch or air switch is limited;
[0003] In occasions where there are a large number of circuit breakers or air switches, the number of equipment controlled by the circuit breakers or air switches is large, the circuit is complex, and the arrangement of circuit breakers or air switches is irregular, which makes it difficult to distinguish and manage circuit breakers or air switches; In the occasions where there are a large number of circuit breakers or air switches, if the anti-misoperation locking device cannot effectively manage the circuit breakers or air switches, it is easy to cause misoperation and lead to safety accidents

Embodiment Construction

[0022] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as Figure 1-6 As shown, an anti-misoperation locking device for a circuit breaker or an air switch according to the present invention includes a left packaging plate 1 , a right packaging plate 2 , an upper limit shaft 3 , a lower limit shaft 4 and an anti-misoperation locking module 5 .

[0024] Such as figure 1 There are a plurality of anti-misoperation locking modules 5, and a plurality of circuit breakers or air switches 8 are installed on the card slot 9, and the circuit breakers or air switches 8 are accommodated in one or more anti-misoperation locking modules 5, the left packaging plate 1 and the chamber formed by the right package plate 2.

[0025] The left package plate 1 and the right package plate 2 are fixed on the circuit breaker or air switch 8 or the card slot 9, such as Figure 6 As sh...

Abstract

The invention discloses a misoperation-preventive locking device for circuit breakers or air switches. The misoperation-preventive locking device comprises a left encapsulation plate, a right encapsulation plate, an upper limiting shaft, a lower limiting shaft and a misoperation-preventive locking module; one or more misoperation-preventive locking modules are arranged between the left encapsulation plate and the right encapsulation plate; the misoperation-preventive locking module comprises an upper cover plate and a lower cover plate; the upper cover plate is composed of an upper panel, an upper left side plate, an upper right side plate and a top panel; the lower cover plate is composed of a lower panel, a lower left side plate, a lower right side plate and a bottom panel; and the upper cover plate and the lower cover plate are mutually connected and locked. The misoperation-preventive locking device for the circuit breakers or the air switches disclosed by the invention is composed of one or more misoperation-preventive locking modules; the number of the misoperation-preventive locking modules can be adjusted according to the number of the circuit breakers or air switches; the upper cover plate and the lower cover plate of the misoperation-preventive locking module are mutually connected and locked; before an operator unlocks a corresponding lock by using a corresponding key, the circuit breakers or the air switches cannot be operated; and thus, the misoperation-preventive locking function of the circuit breakers or the air switches is realized.

Description

technical field [0001] The invention relates to an anti-misoperation locking device for a circuit breaker or an air switch. Background technique [0002] The anti-misoperation locking device can prevent safety accidents and ensure the personal safety of the staff. The size of the anti-misoperation locking devices of circuit breakers or air switches on the market is uniform. The number of circuit breakers or air switches in different occasions cannot be determined, which makes the circuit breaker The application of the anti-misoperation locking device of the switch or air switch is limited; [0003] In occasions where there are a large number of circuit breakers or air switches, the number of equipment controlled by the circuit breakers or air switches is large, the circuit is complex, and the arrangement of circuit breakers or air switches is irregular, which makes it difficult to distinguish and manage circuit breakers or air switches; In the occasions where there are a la...
