Abstract

A generatrix and the corresponding connecting structure used for the high-low voltage switch cabinet relates to the technical field of the main generatrix and the horizontal generatrix, the main generatrix and the vertical generatrix and the corresponding connecting structure in the electric power supplying and distributing switch device. The cross section is a frame-shaped structure with a double 'C' back-to-back shape. The generatrix is package packed through screws and fixed inside the 'T' shaped groove. The screws of the bolts are tightly fixed with the connecting generatrix to make the connection of the power in-and-out of the electricity power device more convenient, ensure the contact pressure and the contact area of the two and make the electric property satisfy the standards. The adoption of the above structure can greatly improve the whole assembling efficiency, lower the producing cost, provide the products with stronger competitive power and simultaneously greatly improve the electric dynamo-thermal stability of the electric properties under the condition of the same electric current.

Description

A kind of high and low pressure switch cubicle bus and syndeton thereof

Technical field

The technical field of main bus bar in the switching device that a kind of power supply and distribution of electric power is used and horizontal bus, main bus bar and vertical bus and syndeton thereof refers in particular to the technical field of main bus bar, bus, vertical bus and syndeton thereof in a kind of high and low voltage switch cabinet.

Background technology

As the low-tension switch cabinet of conveying and electrical power distribution after the step-down of electric power network high-tension switch cabinet, it has been widely used in different places.At present low-tension switch cabinet mainly is divided into fixed, fixedly three kinds of cellular-type and pull-out types, wherein the utility model bus volume of the low-tension switch cabinet of three kinds of patterns little, take up an area of less, feeding circuit is many, dynamic and thermal stability ability height, advantage such as restore electricity rapidly, and be subjected to liking of user deeply.But because commercially available busbar cross-section all is I type or L type, so for the high-pressure and low-pressure switch cubicle, when assembling main bus bar and bus and vertical bus, need measure the length of required bus in advance, connecting boring respectively on main bus bar, the vertical bus, successively that they are fixedly connected with bolt at last then, as seen in this operation, location and installation step are many, very bother, thereby production efficiency are also low, owing to measure and bore error, the bus after the whole assembling is not attractive in appearance yet simultaneously.For this reason, a kind of new main bus bar is devised, as Chinese utility model ZL 022216361.1 " low-tension switch cabinet vertical bus ".By cooperating of fitting recess and special bolt, can easily main bus bar be connected with bus and vertical bus, this design has overcome above-mentioned part defective, operation is simplified relatively, but because feeding circuit is more, fixed and fixedly cellular-type switch cubicle assembling, the workload of bus mainly is connected with bus between the connection bus at main bus bar, bus, vertical bus, thereby solved the problem of alignment tolerance at all, also improved simultaneously production efficiency, but also have actual deficiency, as be of limited application, heat dispersion still can further improve.

Summary of the invention

Primary technical problem to be solved in the utility model is to overcome above-mentioned defective, provides a kind of and locatees that convenience, zero allowance, electric contact pressure guarantee, high and low pressure switch cubicle bus simple to operate.

Another technical problem to be solved in the utility model provides and a kind ofly can satisfy electric property, bus connection structure convenient to operation.

The technical scheme that the above-mentioned primary technical problem that solves the utility model adopts is: a kind of high and low pressure switch cubicle bus, it is that a kind of strip, integral body are the metallic bus bar of section bar, it is characterized in that described bus transverse section of section material is back-to-back shaped as frame structure, top and bottom have open slot, and the open slot width is less than interior well width.Bus is connected with other metallic bus bar by inside groove.

Described shaped as frame structure adopts two " C " types shape back-to-back, and the both ends open groove is a T-slot.

Described open slot inner end is a contact-making surface, and the two sides open slot all can connect.

Face forms the groove of heat radiation about described bus section bar, preferred arc groove, the heat dispersion of raising bus.

Described bus section bar adopts the arc-shaped transition reinforcement in the open slot corner portions, improves the intensity of bus.

The utility model solves the technical scheme that above-mentioned another technical problem adopted: a kind of above-mentioned high and low switch cubicle syndeton of bus, it is characterized in that comprising T type bolt, nut and pad, the head of T type bolt stretches in the notch of open slot and turns to, the screw portion of nut is fastened by pad, nut and connection bus, and it carries out one side as required and connection is installed or carries out two sides installation connection.

Compared with prior art, advantage of the present utility model is: by the double C-type of main bus bar, bus, vertical bus, open slot is T type groove and special bolt matches, and makes bus remove the operation of boring from, make the installing and locating of itself and other bus convenient, the bus integral body after the assembling is also attractive in appearance; Moreover, guaranteed contact pressure and contact area between the two, electric property is met the requirements fully.In sum, adopt the bus of said structure, want so that the capacity of bus reaches 4000A-6000A, dynamic thermal stability can reach 220kA, 100kA respectively, and under the equal conditions, material can be saved about 20%, and whole efficiency of assembling is improved greatly, reduced production cost thus, also improved moving, thermally-stabilised ability simultaneously greatly, made product have stronger competitiveness.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, this bus 4 is the strip that host material is made with T2 copper mainly, whole special-shaped busbar, its section bar 2 cross sections are the shaped as frame structure that has the twoport groove, these back-to-back two " C " type shaped as frame structures, above 1 and following 1 ' have open slot 3, in the present embodiment, open slot 3 is T type groove, at notch 5 width of this T type groove, less than interior well width.

See Fig. 2 and Fig. 5 with the T type bolt 6 that above-mentioned bus 4 matches, the minor face of the head 11 of this bolt 6 is less than or equal to T type groove notch 5 width on the bus 4, make the head 11 of this bolt 6 can enter in the above-mentioned T type groove notch 5 and can rotate 90 °, bus 4 and bolt 6 are tentatively coupled together, and the screw rod of bolt 6 passes connection bus 7 and special-purpose pad 8,9 backs couple together with nut 10.

Fig. 3 is the signal of bus single face mounting structure, and Fig. 4 is the two-sided mounting structure signal of bus.

Further improve, see Fig. 6, bus section bar 2 face about it forms the arc groove 12 of heat radiation, and is both beautiful and practical, and the bus section bar has also adopted arc-shaped transition reinforcement 13 in open slot 3 corner portions, plays necessary humidification, improves the intensity of bus.
