Abstract
The utility model discloses a safety closure plate sliding device for a drawout breaker, which comprises a base, a spring, a support base, a mandrel, a lower seal plate and an upper seal plate, four-phase bus bar slot holes and Z-shaped holes are respectively machined on the base, the lower seal plate and the upper seal plate, the lower seal plate and the upper seal plate are mounted in the base through sliding slots; the mandrel is in Z-shaped structure and is provided with oblique wedges on both sides, the mandrel is inserted into the Z-shaped holes of the base, the lower seal plate and the upper seal plate to be pressed, then the oblique wedges on both sides of the mandrel push the lower seal plate and the upper seal plate mounted above the base so that the four-phase bus bar slot holes on the lower seal plate and the upper seal plate coincide with the four-phase bus bar slot holes on the base to form the through holes of the four-phase bus bar slot holes, thereby realizing the reliable connection of a main switch blade and a drawer base lead-out bus bar.
Description
Technical field:
The utility model relates to the major loop of drawout chassis part in a kind of drawout breaker and the safety insulating device of main body switch major loop, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology:
The main body switch of drawout breaker passes in and out translation in drawout chassis, when realizing reliably being connected with the major loop of drawout chassis, according to the regulation in GB14048.2 " low voltage switchgear and control appliance part 2: the circuit breaker " standard, safe closing plate carriage to drawout chassis has two requirements: the one, and the row of patching of body switch enters drawout chassis realization major loop and connects when powering, require safe closing plate before the row of patching enters, reliably to open earlier, so that the row of patching enters drawout chassis, the realization body switch is connected with the reliable of drawout chassis; The 2nd, patching of body switch got rid of when drawout chassis is changed or overhaul, require safe closing plate can patch get rid of from after reliable again closure, in order to avoid charged drawout chassis major loop is exposed the potential safety hazard of bringing operation to get an electric shock for on-the-spot operative employee or electric power overhaul personnel.
Present sliding device of drawout breaker safe closing plate complex structure, related number of spare parts is many, causes movement locus unreliable, causes the phenomenon of stuck (do not open in advance or can not reliably closed) easily.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provide a kind of simple in structure, part is few, the reliable sliding device of drawout breaker safe closing plate of handling safety.
A kind of sliding device of drawout breaker safe closing plate described in the utility model includes parts such as pedestal, spring, bearing, push rod, following shrouding, upper sealing plate, and pedestal and bearing are T-shaped overall structure; Both sides at pedestal are provided with chute, and following shrouding, upper sealing plate are installed in the pedestal by chute; On pedestal, following shrouding, upper sealing plate, offer four phase busbar slotted eyes and Z-shaped hole respectively; Push rod is Z-shaped structure, is inserted in the Z-shaped hole of pedestal, following shrouding, upper sealing plate; Be provided with tiltedly in the both sides of the push rod that is Z-shaped structure and carve; Push rod is inserted pedestal, descends in the Z-shaped hole on shrouding, the upper sealing plate, and when pressing down, the both sides of push rod tiltedly carve following shrouding and the upper sealing plate that promotes to be installed on the pedestal top, make down four on four phase busbar slotted eyes and the pedestal on shrouding, the upper sealing plate mutually the busbar slotted eye overlap, form the through hole of four phase busbar slotted eyes, like this, can realization body switch slotting tool and reliable connection of drawout chassis outlet busbar.
Be skillfully constructed through the utility model after the above-mentioned design, simple in structure, making capacity, easy for installation, it has not only simplified the structure of existing drawout chassis safe closing plate carriage greatly, has reduced production cost, and significantly in the reliability that has improved work.

Embodiment
A kind of sliding device of drawout breaker safe closing plate described in the utility model includes parts such as pedestal 1, spring 2, bearing 8, push rod 3, following shrouding 4, upper sealing plate 5, and pedestal 1 is T-shaped overall structure with bearing 8; In the both sides of pedestal 1, be provided with chute 9, following shrouding 4, upper sealing plate 5 are installed in the pedestal 1 by chute 9; On pedestal 1, following shrouding 4, upper sealing plate 5, offer four phase busbar slotted eye 7 and Z-shaped holes 6 respectively; Push rod 3 is Z-shaped structure, is inserted in the Z-shaped hole of pedestal 1, following shrouding 4, upper sealing plate 5; Be provided with in the both sides of the push rod that is Z-shaped structure and tiltedly carve 10.Under general situation, be arranged at four phase busbar slotted eyes 7 on pedestal 1, following shrouding 4, the upper sealing plate 5, stagger mutually, be closed state, the wiring busbar can't pass through four phase busbar slotted eyes 7; In the Z-shaped hole 6 on push rod 3 insertion pedestals, following shrouding, the upper sealing plate, the spring 2 in lower compression is installed on bearing 8 firmly, at this moment, be arranged at tiltedly carving of push rod 3 both sides and 10 produce a horizontal thrust to both sides, promotion is installed on the following shrouding 4 and upper sealing plate 5 of pedestal top, make down four on four phase busbar slotted eyes 7 and the pedestal 1 on shrouding 4, the upper sealing plate 5 mutually busbar slotted eye 7 overlap, like this, promptly formed the through hole of four phase busbar slotted eyes 7 on pedestal 1, following shrouding 4, the upper sealing plate 5, like this, can realization body switch slotting tool and reliable connection of drawout chassis outlet busbar.
When put on the push rod 3 after the power that presses down is cancelled, the elastic force that is installed on the spring 2 in the bearing 8 jack-up push rod 3 that makes progress, therefore carving 10 by 3 liang of skew backs of push rod is produced a horizontal thrust to both sides and is also disappeared, at this moment, following shrouding 4, upper sealing plate 5 are got back to the home position, four phase busbar slotted eyes 7 on following shrouding 4, the upper sealing plate 5, with four on the pedestal 1 mutually busbar slotted eye 7 stagger mutually, can realization body switch slotting tool and the reliable isolation of drawout chassis outlet busbar.
