Description

Anti-error shock automatics

The utility model relates to the field of electrical equipment of electricity, relates to a kind of anti-error shock automatics of withdraw-type switch cabinet particularly.

In the prior art, the anti-error shock in the generating of electric power, power transformation or distribution field normally adopts the work of taking ticket, special messenger's monitoring, work permit, work control measures such as termination and power failure, electrical verification, overlap joint ground wire, technical measures such as chain, though this method has the advantage of anti-error shock, also there is following shortcoming simultaneously: the one, it is loaded down with trivial details, and it is many to involve personnel, the needs of the training programmes are heavy, spring a leak easily; The 2nd, some technological means device structure complexity, complex operation, operating personnel require height and part fragile, failure rate height, poor reliability.Along with the development of society, progress of science and technology, people thirst for appearing on the market of a kind of novel anti-error shock automatics, to satisfy the people's work needs.

The purpose of this utility model provides a kind of anti-error shock automatics, and it was both simple in structure, and full-automatic again, easy and simple to handle, protective capacities is strong, and is safe and reliable.

The purpose of this utility model is to realize by following technical scheme.Promote driving mechanism and seal two blocks of shroudings of upper and lower two contact mouths with the base of circuit breaker, when entering switch cubicle to reach circuit breaker, two blocks of shroudings are removed from the contact mouth, and contact of breaker contacts with contact knife, and switch cubicle can normally move; When circuit breaker was removed, two blocks of shroudings were realized the purpose of full-automatic anti-error shock automatically with two contact knife mouth shutoff and locked.The main feature of its structure is to be provided with dividing plate 8 in switch tank bracket 1, and its middle and upper part is provided with contact knife mouth 3,10, and contact knife 4,11 and upper and lower shrouding 2,12 match with it respectively; Its both sides are provided with side plate 13, and the two ends of upper and lower shrouding 2,12 are inserted between dividing plate 8 and the side plate 13, can do directed the slip.Be respectively equipped with connecting plate 6 and 9 on upper and lower shrouding 2,12 corresponding positions, its two a end connects upper and lower shrouding 2,12 respectively, and the other end connects lever 7 respectively, is provided with axle 5 at the middle part of lever 7, connects solid with dividing plate 8 it; The bottom of tank bracket 1 connect by axle 16 drive plates 15 on the angle, its inferior horn is equipped with wheel 20, left comer is connected with following shrouding 12 by connecting rod 14, the limit on it between angle and left comer is provided with groove; The right of drive plate 15 connect by axle 18 lockplates 19 on the angle, its inferior horn is equipped with wheel 21, its left comer is equipped with a stub 17 and matches with the groove of drive plate 15, the realization lock function.

Its dividing plate 8, upper and lower shrouding 2,12, side plate 13 usefulness insulating material are made.

The utility model is because the employing drive plate drives the structural design of upper and lower shrouding sealing contact knife mouth, so it is rationally novel in design, simple in structure; Simultaneously because it is provided with the mechanism that drive plate drives upper and lower shrouding and lockplate lock drive plate, so when circuit breaker is removed switch cubicle, the automatic shutoff of contact knife mouth, when circuit breaker enters switch cubicle, touching knife-edge part removes automatically, but contact of breaker inserts operate as normal, can prevent error shock effectively.Be that safe and reliable so operating personnel need not special training, market potential is big, is suitable for the industry and popularizes because it is easy and simple to handle, and its parts are durable again.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural front view according to the anti-error shock automatics that the utility model proposes.

Fig. 2 is the A-A profile of Fig. 1.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2 according to the anti-error shock automatics that the utility model proposes.This device comprises switch tank bracket 1, is provided with dividing plate 8 (as shown in Figure 1) in it.Its middle and upper part is provided with contact knife mouth 3,10, be installed in contact knife 4,11 and upper and lower shrouding 2,12 on the tank bracket by insulator 22, match with it respectively, its both sides are provided with side plate 13, insert between dividing plate 8 and the side plate 13 at the two ends of upper and lower shrouding 2,12, can do directed the slip, not tilt to guarantee upper and lower shrouding 2,12.Be respectively equipped with connecting plate 6 and 9 on upper and lower shrouding 2,12 corresponding positions, its two a end connects upper and lower shrouding 2,12 respectively, and the other end connects lever 7 respectively, and the middle part connects solid with dividing plate 8 it with axle 5.Be installed on the drive plate 15 and the lockplate 19 of tank bracket 1 bottom by axle 16,18, for the last angle of triangle gusset (as shown in Figure 2) its two connects solid on tank bracket 1 with axle 16,18, its inferior horn is equipped with wheel 20,21 respectively, the left comer of drive plate 15 is connected with following shrouding 12 by connecting rod 14, stub 17 on being provided with groove and being installed in lockplate 19 left comer between its left comer and the last angle matches, and realizes function is locked, opened to this device.Said mechanism is two symmetrical fully covers, finishes same function simultaneously, keeps the balance of movement of this device.

Its course of work is summarized as follows: when circuit breaker push-on switch cabinet, the base of circuit breaker at first promotes the wheel 21 of lockplate 19, and it is rotated around axle 18, lifts on the stub 17, goes out the groove release of drive plate 15.Circuit breaker pushes away before continuing, its base just promotes the wheel 20 of the inferior horn of drive plate 15, and drive plate rotates around axle 16, lifts on the left comer, lift on the connecting rod 14, move on the following shrouding 12, by the effect of lever 7 and connecting plate 9 and 6, upper sealing plate 2 moves down simultaneously, so two contact knife mouths 3 and 10 are opened simultaneously, at this moment, contact of breaker just can be gone into contact knife mouth 3 and be contacted with contact knife 4 with 10, the operation (not drawing among the figure) of just can switching on.

When circuit breaker left switch cubicle, the circuit breaker base was recessed the wheel 20 of drive plate 15, and drive plate 15 utilizes deadweight, and around axle 16 counter-rotatings, connecting rod 14 falls.Descend simultaneously shrouding 12 to move down, move on the upper sealing plate 2, with 3,10 shutoff of two contact knife mouths.Circuit breaker continues the outer wheel 21 of recessing lockplate 19 that moves, and relies on from recoiling axle 18 counter-rotatings, and the stub 17 at one angle falls in the groove of drive plate 15, at this moment with two shroudings 2 and 12 locked at contact mouth 3 and 10 places, reaches the purpose of full-automatic anti-error shock.It is easy and simple to handle, and is safe and reliable.
