Abstract
The utility model discloses a safety device used for preventing misoperation of a vacuum circuit breaker. The safety device comprises a transparency cover plate the back of which is equipped with two or four pieces of magnetic stripe. Disposed on housing of a VSI type mechanism, the safety device capable of shielding switch on and switch off buttons effectively prevents miscontact operation in order to achieve an effect of error locking prevention and increase safety utilization rate of equipment.
Description
Technical field:
The utility model relates to a kind of power equipment safety protective device, particularly relates to a kind of vacuum circuit-breaker safety device against false manoeuvres.
Background technology:
Fast development along with economy, electric utility is also thereupon fast-developing, various power equipments are more and more, in some accident potential of existence in service of power equipment, as: VSI type mechanism breaker tripping and closing button is exposed outside, and this button outside is covered without locking device, cause easily personnel's malfunction breaker tripping and closing, affect normal power supply, and then affect enterprises and institutions and resident's electricity consumption, cause great economic loss.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of simple in structure, easy accessibility is provided and can prevents the vacuum circuit-breaker safety device against false manoeuvres of misoperation.
The technical solution of the utility model is: a kind of vacuum circuit-breaker safety device against false manoeuvres, contain transparent cover plate, and it is characterized in that: the back side of described transparent cover plate is provided with magnetic stripe.
Described transparent cover plate is rectangle, and its back side arranges two described magnetic stripes, and two described magnetic stripe symmetrical parallel distribute.
Perhaps, described transparent cover plate is rectangle, and its back side arranges four described magnetic stripes, four in twos symmetrical parallel distributions of described magnetic stripe.
The beneficial effects of the utility model are:
1, the utility model is arranged on the VSI type mechanism shell, can block the breaker tripping and closing button, effectively prevents from bumping operation by mistake, plays the effect of anti-misoperation locking, has improved the safe handling rate of equipment.
2, the utility model adopts magnetic stripe to be fixed, and easily dismounting when needing breaker tripping and closing, is taken transparent cover plate off and got final product, and is simple.
3, simple in structure, the easy accessibility of the utility model and can prevent misoperation, it is applied widely, is easy to promotion and implementation, has good economic benefit.
Description of drawings:
Fig. 1 is the structural representation of vacuum circuit-breaker safety device against false manoeuvres;
Fig. 2 is the use state diagram of vacuum circuit-breaker safety device against false manoeuvres shown in 1.
Embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-transparent cover plate, 2-magnetic stripe, 3-VSI type mechanism shell, 4-opening button, 5-shift knob, 6-switch knob.
The vacuum circuit-breaker safety device against false manoeuvres contains transparent cover plate 1, and wherein: the back side of transparent cover plate 1 is provided with magnetic stripe 2.
During use, transparent cover plate 1 is fixed on VSI type mechanism shell 3 by magnetic stripe 2, blocks opening button 4, shift knob 5 and switch knob 6 fully, effectively prevents from bumping operation by mistake.When needing breaker tripping and closing, take transparent cover plate 1 off and get final product, simple.
