Abstract
The invention discloses a sliding device of a safety sealing plate of a drawout breaker, which comprises a base, a spring, a support, an ejector rod, a lower sealing plate, an upper sealing plate and the like, wherein the base, the lower sealing plate and the upper sealing plate are respectively provided with a four-phase busbar slot hole and a Z-shaped hole, and the lower sealing plate and the upper sealing plate are arranged in the base through sliding grooves; the ejector rod is of a Z-shaped structure, the two sides of the ejector rod are provided with wedges, the ejector rod is inserted into the Z-shaped holes of the base, the lower sealing plate and the upper sealing plate, and when the ejector rod is pressed downwards, the wedges on the two sides of the ejector rod push the lower sealing plate and the upper sealing plate which are arranged above the base, so that the four-phase busbar slotted holes on the lower sealing plate and the upper sealing plate are superposed with the four-phase busbar slotted holes on the base to form through holes of the four-phase busbar slotted holes, and thus, the reliable connection of the main switch slotting tool and the drawer base outgoing line busbar can.
Description
Technical field:
The major loop of drawout chassis part and the safety insulating device of main body switch major loop belong to low-voltage electrical apparatus manufacturing technology field in the present invention and a kind of drawout breaker.
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 gets into drawout chassis realization major loop and connects when supplying power; Require safe closing plate before the row of patching gets into, reliably to open earlier, so that the row of patching gets into 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 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 invention is to 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 of the present invention 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 through 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 in the Z-shaped hole on pedestal, following 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 busbar slotted eye coincidences mutually on four phase busbar slotted eyes and the pedestal on shrouding, the upper sealing plate, 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.
The present invention through after the above-mentioned design is skillfully constructed, simple in structure, making capacity, easy for installation, and 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 of the present invention 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 through 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 each other, be closed state, the wiring busbar can't pass through four phase busbar slotted eyes 7; Push rod 3 is inserted in the Z-shaped hole 6 on pedestal, following shrouding, the upper sealing plate; The spring 2 in lower compression is installed on bearing 8 firmly at this moment, is arranged at tiltedly carving of push rod 3 both sides and 10 produces 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 pedestal 1, the through hole of four phase busbar slotted eyes 7 on shrouding 4, the upper sealing plate 5 down; 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 is carved 10 by 3 liang of skew backs of push rod and is produced a horizontal thrust also so disappearance to both sides, 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 each other, can realization body switch slotting tool and the reliable isolation of drawout chassis outlet busbar.
