Abstract
The utility model relates to an anti-maloperation knife switch which comprises a switch base plate, a moving contact knife, a static contact seat and a handle. The technical solution is that the handle is fixedly provided with a cover plate that is covered over the moving contact knife; a mechanical interlocking device is disposed between the cover plate and the switch base plate; and the base plate is provided with an electrical interlocking device which is connected with a breaker.
Description
Technical field
The utility model relates to a kind of anti-misoperation knife switch.
Background technology
Snap close knife switch of the prior art is no padlock knife switch, does not cause personal shortcoming of getting an electric shock easily owing to there is safety measure to exist.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned defective of prior art, and a kind of anti-error formula snap close knife switch with safety interlocking is provided.
The utility model comprises switch baseplate, movable touch knife, static contact seat, handle; Its technical solution is on described handle, to be fixed with cover plate; Cover plate covers the top of movable touch knife; Between cover plate and switch baseplate, be provided with mechanical interlocking device, on base plate, be provided with the electrical interlocks device, this electrical interlocks device is connected with circuit breaker.
The cover plate of the anti-error formula snap close knife switch of said structure can block from live components, can effectively prevent the accident of human electric shock who causes because of misoperation; Described mechanical interlocking device can prevent misoperation; Described electrical interlocks device can prevent the knife switch hot line job, reduces potential safety hazard.
Description of drawings
Further illustrate the particular content of the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1: the structural representation of present embodiment.
The end view of Fig. 2: Fig. 1.
The B of Fig. 3: Fig. 1 is to partial view.
Embodiment
As shown in the figure; The utility model comprises switch baseplate 1, movable touch knife 2, static contact seat 3, handle 4; On handle 4, be fixed with cover plate 5, cover plate 5 covers the top of movable touch knife 2, between cover plate 5 and switch baseplate 1, is provided with mechanical interlocking device; On base plate 1, be provided with the electrical interlocks device, this electrical interlocks device is connected with circuit breaker.Described mechanical interlocking device comprises the buckle structure of device between cover plate and switch baseplate or its fixture; Described electrical interlocks device comprises being fixed on to have the electric switch of linkage structure with described mechanical interlocking device on cover plate or the switch baseplate, and this switch is connected with circuit breaker and controls release.
In the present embodiment, described mechanical interlocking device comprises the sensitive switch 6 that is fixed on the switch baseplate 1, and this sensitive switch 6 is provided with a horizontal groove; On cover plate 5, be provided with push rod 7, push rod 7 drives lock bolt 9 motions through connecting rod 8, and this lock bolt 9 is arranged on over against the position of sensitive switch 6 grooves, and push rod 7 is provided with operation part, and this operation part is exposed above handle 4.In the utility model, this operation part also can be exposed above cover plate 5.
In the present embodiment, described electrical interlocks device comprises the switch triggering part that is arranged in sensitive switch 6 grooves, and this sensitive switch 6 connects the circuit breaker of control release.
Knife switch is when closure, and through the operation part mobile putter of push rod, the transmission through connecting rod enters in the groove of sensitive switch lock bolt again.This moment, the handle of knife switch can not be by direct pull-up owing to the effect of lock bolt, and sensitive switch is not controlled release simultaneously.When needs break off knife switch; Need through push rod lock bolt to be withdrawed from from the groove of sensitive switch earlier; When lock bolt withdraws from, trigger the triggering part of this sensitive switch from the groove of sensitive switch, make sensitive switch trigger circuit breaker action and the dropout of control release, make the knife switch outage.Effectively prevented to forget the potential safety hazard that the disconnection release causes because of human error.
