Description

Little bus jumper

One. technical field: the utility model relates to a kind of new clothes of the little bus in electric power system secondary specialty screen top and jumper device of transformation of being used for, and particularly relates to a kind of little bus jumper.

Two. background technology: the 10KV that present domestic protective relaying device producer forms a complete production network and the protection screen of above electric pressure, AC and DC power supply that its device is required and secondary AC voltage sample value all must be extracted from each double-deck little bus that screen screen top is installed.New install and engineered in the double-deck little bus in protection screen screen top adopt whole copper busbar to be communicated with to lay more, the little bus between the minority protection screen is then by the self-made hard lead connection of relaying protection personnel.Its workflow is to go up connection by whole copper busbar (perhaps many hard leads are held the circle back) is fixed on little bus row with screw; though this method is effective; but workflow is trifling, efficient is low, installation cost is high; particularly need change and move back screen and protection when transforming with DC power supply when protection screen; because the relaying protection personnel need transform jumper connection work to little bus; workload is big, dangerous spot is many, and its work is summarized as follows:

1, all little buses that need to withdraw between two protection screens that the secondary screen faces are mutually jumped logical;

2, remove by root with the personality kit little bus that screw is the fixing hard lead of circle (or hold);

3, the secondary screen little bus two ends, top that will newly install and the little bus of adjacent screen are jumped to lead to and are connect.

Because working space is narrow and small, has only 30mm with the spacing between the little bus of layer, the spacing of two-layer little bus also has only 60mm up and down, the dismounting of using common screwdriver to carry out screw under little bus ruuning situation is difficult to set about, and the lead of each frequent crimping above the screw is many, can only wrap up tight diagonal cutting pliers with insulating tape and go strand, the bare metal that strand is had no progeny partly also must be wrapped up, these disconnect Shi Douhui at little bus and bring very big workload and dangerous spot, and each step work all must be careful, such pattern must increase the time of this type of work greatly, has also caused two task dangerous spots many.

Three. the utility model content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, not only be convenient to install but also little bus jumper easy to use.

The technical solution of the utility model is: a kind of little bus jumper, contain base, described base top is provided with the insulation module, described insulation module is provided with bolt hole, be set with conducting bolt in this bolt hole, described conducting bolt bottom is set with the conduction clamp, be combined with adjusting nut on the conducting bolt of this conduction clamp below, described conducting bolt top is combined with two locking nuts, and, the upper end of described conducting bolt screws by screw thread and extending bore post lower end and links together, and described two contacted end faces of locking nut are enclosed with insulation material layer for the conduction end face on other surfaces.

Described conduction clamp upper surface is provided with the V-type draw-in groove, and described insulation module lower surface is provided with arc-shaped slot, and described V-type draw-in groove is corresponding with described arc-shaped slot.

Described conducting bolt is made by copper rod, and its center, upper end is provided with screwed hole, and this screwed hole screws mutually with the screw rod of described extending bore post lower end, and center, described extending bore post upper end is provided with extending bore.

The beneficial effects of the utility model are:

1, the utility model can reduce by two task dangerous spots in protection screen new clothes and the replacing process, reduces workload, increases work efficiency.

2, the utility model volume is little, in light weight, rotates the distance that can regulate between conduction clamp and the insulation module by nut, is the little bus cross-over connection of 6mm and 8mm so that adapt to internal diameter.

3, the utility model can be used for old protection screen, central signal screen, the central signal relay screen of 500KV and following the old and new transformer station and combine from collapsing of little bus of screens such as the protection screen of transforming the back new clothes, observing and controlling screen, telemechanical screen top connecing work, has characteristics such as manufacturing cost and use cost is low, replacing convenience, applied range, operating efficiency height.

Four. description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of parts among Fig. 1;

Fig. 3 is user mode figure of the present utility model.

Five. embodiment:

Embodiment: referring to Fig. 1-Fig. 3, among the figure, 1-underframe, 2-adjusting nut, 3-conduct electricity clamp, 4-conducting bolt, the 5-module that insulate, 6-locking nut, 7-extending bore post, the little bus of 8-, 9-test lead, the hard lead of 10-.

Little bus jumper contains base 1, base 1 top is provided with insulation module 5, insulation module 5 is provided with bolt hole, be set with conducting bolt 4 in this bolt hole, conducting bolt 4 bottoms are set with conduction clamp 3, be combined with adjusting nut 2 on the conducting bolt 4 of these conduction clamp 3 belows, conducting bolt 4 tops are combined with two locking nuts 6, and, the upper end of conducting bolt 4 spins together by screw thread and extending bore post 7 lower ends, two locking nut 6 contacted end faces are enclosed with insulation material layer for the conduction end face on other surfaces.

Conduction clamp 3 upper surfaces are provided with the V-type draw-in groove, and insulation module 5 lower surfaces are provided with arc-shaped slot, and the V-type draw-in groove is corresponding with arc-shaped slot, so that the little bus 8 of clamping.

Conducting bolt 4 is made by copper rod, and its center, upper end is provided with screwed hole, and this screwed hole screws mutually with the screw rod of extending bore post 7 lower ends, and center, extending bore post 7 upper end is provided with extending bore.

During use; can realize that by the Metal Contact face between the locking nut 6 hard lead 10 is jumped logical and extending bore is realized the dual electrically conducting manner that test lead 9 is pegged graft; the mode of extending bore grafting test lead 9 has satisfied the on-the-spot interim requirement of jumping the little bus 8 in logical both sides of needs in the screen work of moving back; the working method of hard lead 10 conductions has satisfied the requirement of little bus 8 long-time running, can reduce protection again greatly and order retainers, servants, etc. to retire the medium and small bus 8 of screen work required operating time of jumper connection back and forth.
