Abstract

The present invention relates to a low-pressure electric transmission and distribution equipment, and relates to a bus-bar socket which is installed on the casing of the low-pressure bus-bar groove and is used for leading out branching bus-bar from the bus-bar. The bus-bar socket comprises a baseboard and an upper cover, the baseboard is arranged with a plurality of inserting holes, the baseboard and one side of the upper cover are hinged to each other with a hinge, and the baseboard and the other side of the upper cover are connected with shackles that are assorted to each other; the edge of the upper surface of the baseboard is arranged with a sealing groove which is accommodated with a sealing pad with rubber or silica gel material, correspondingly, the edge of the upper cover is arranged with a sealing groove and a projecting rib corresponding with the shape of the sealing pad, facilitating that the projecting rib can be jointed and sealed with the sealing pad in the closing of the upper cover. The equipment of the invention has the advantages of simple structure, convenient using, good insulating and protecting property and good insulating property between the phases.

Description

Bus plug

Technical field

The invention belongs to the low pressure equipment for power transmission and distribution, relate to a kind of being installed in and be used for drawing the bus plug of branch bar on the low-voltage bus bar slot shell from bus.

Background technology

Existing bus plug product generally comprises the base plate and a loam cake that covers on base plate that can be fixedly mounted on the bus duct, is distributed with on the base plate and each corresponding heterogeneous interface that is used for inserting plug assembly in bus position mutually.When not needing to draw branch bar, the loam cake of bus plug lid is connected onboard and by securing member or locking device, is used for interface is protected; When needs are drawn branch bar, then loam cake is opened, plug assembly is inserted interface, conduct electricity with bus in the bus duct and be connected.The major defect that the bus plug of this traditional class formation exists is: 1, loam cake and base plate are separable structure, and the not only process inconvenience of Da Kaiheguanbiing, and loam cake is lost easily and made interface can not get protection; 2, poorly sealed between loam cake and the base plate, water, vapour are entered, influence its insulating protection performance; 3, the upper surface of base plate is a smooth surface, thereby the creepage distance that respectively plugs between the mouth that distributes thereon is shorter, and the phase insulation ability is lower.

Summary of the invention

Technical problem to be solved by this invention is, a kind of simple in structure, easy to use, the insulating protection performance is good, the phase insulation ability is strong bus plug is provided.

Bus plug of the present invention includes base plate and loam cake, and base plate is provided with several spliced eyes, and a side of base plate and loam cake is hinged by hinge, and the opposite side of base plate and loam cake is connected by the snap close that cooperatively interacts; The edge of described plate upper surface has seal groove, be mounted with the sealing gasket of rubber or silica gel material in the seal groove, corresponding with it, be provided with and seal groove and the corresponding convex tendon of sealing gasket shape at the edge of loam cake, make when loam cake covers that convex tendon can engage sealing with sealing gasket.

The bottom of described seal groove also compartment of terrain is distributed with several location holes, in the relevant position of sealing gasket bottom bossed reference column is set simultaneously, and the external diameter of reference column is slightly larger than the internal diameter of location hole, and reference column is pressed in the location hole by strain.The outer surface of described reference column also can be provided with rib longitudinally, so that reference column is easier to be pressed in the location hole.

Also be distributed with many grooves on the described plate upper surface, all have groove that it is separated between the adjacent spliced eye.

Be provided with a barrier in described each spliced eye, spliced eye is divided into two dead slots side by side, the top in this barrier cross section is circular arc.

The lower surface edge of described base plate also has the bottom surface seal groove, is mounted with base gasket in the seal groove of bottom surface, the interior external seal when being connected with bus duct in order to the assurance base plate.

Advantage of the present invention is: 1, loam cake and base plate one end are hinged, an end is sealed, have both made things convenient for to use also to be difficult for losing the protection that influences spliced eye because of loam cake; 2, between loam cake and the base plate with and base plate and bus duct between sealed engagement, improved its insulation and moisture performance greatly; 3, the location hole by the bottom positions with reference column and is connected between sealing gasket and the seal groove, makes and has improved dependability by the sealing gasket difficult drop-off; 4, the groove of plate upper surface setting has increased the creepage distance between the spliced eye, has improved alternate insulating capacity.

Embodiment

As shown in Figure 1, this bus plug comprises base plate 1 and loam cake 2, and base plate is provided with several spliced eyes 3, and a side of base plate and loam cake is hinged by hinge 4, and opposite side connects by the snap close 5 that cooperatively interacts; The edge of plate upper surface has seal groove 6, is mounted with the sealing gasket 7 of rubber or silica gel material in the seal groove, is provided with convex tendon 8 at the edge of loam cake simultaneously, and when loam cake covered, convex tendon 8 and sealing gasket 7 tight pressings were realized sealing.

As Fig. 2, shown in Figure 3, be distributed with several location holes 9 bottom interval of seal groove 6, as shown in Figure 5, bossed reference column 10 be set simultaneously in sealing gasket 7 bottoms, the external diameter of reference column 10 is slightly larger than the internal diameter of location hole 9, and reference column is pressed in the location hole by strain.In addition, as Fig. 5, shown in Figure 6, the outer surface of reference column also is provided with rib 11 longitudinally, so that reference column is easier to be pressed in the location hole.

As shown in Figure 2, the groove 12 that distributes on the plate upper surface is separated between each spliced eye 3, to increase the creepage distance that respectively plugs between the hole, improves the phase insulation performance.The barrier 13 that is provided with in each spliced eye is divided into two dead slots side by side with spliced eye, barrier 13 cross sectional shapes as shown in Figure 4, its top is circular arc, can access guiding when plug assembly is inserted, thereby is easier to insert.

As shown in Figure 7, the lower surface edge of base plate 1 is provided with bottom surface seal groove 14, is mounted with base gasket 15 in the seal groove of bottom surface, the interior external seal when being connected with bus duct in order to the assurance base plate.
