Abstract

The utility model discloses a low voltage bus duct in the technical field of low voltage power transmission and distribution equipment and aims to solve problems of low dielectric strength among conductive terminal rows and large bus duct mounting spans existing in the prior art. The low voltage bus duct comprises a hollow duct body, wherein the duct body is formed by fixedly connecting upper and lower cover plates and left and right cover plates, the duct body is internally fixed with a plurality of the conductive terminal rows side by side with intervals, upper and lower insulation supporting frames which are integrated with the duct body into one body are arranged among the conductive terminal rows, and the conductive terminal rows are mutually in fixed connection through insulation bolts. The low voltage bus duct has a compact structure as well as a small space occupation volume and can fully guarantee reliable connection at connection portions of the conductive terminal rows and mutual excellent insulation performance.

Description

Low voltage bus bar groove
Technical field
The utility model relates to a kind of low pressure equipment for power transmission and distribution, particularly a kind of low voltage bus bar groove.
Background technology
Along with emerging in large numbers of modernization project facility and equipment, the power consumption of all trades and professions is fast to be increased, the appearance in especially numerous skyscrapers and large-sized workshop workshop, can not meet the demands in the now large electric current conveying system of traditional cable as transmission pressure, the parallel connection of multiway cable is used to on-the-spot installation connection and has been brought inconvenience.Plug type bus duct arises at the historic moment as a kind of novel distribution wire, compares with traditional cable, demonstrates fully its superiority when large electric current is carried.
A kind of low voltage bus bar groove is arranged in the prior art, comprise upper and lower cover plates, left side plate, wearing layer and conducting terminal row, conducting terminal row be fixed in the bus duct of hollow, be respectively equipped with wearing layer between conducting terminal row and the upper and lower cover plates, left side plate is up and down forming I-shaped structure between two cover plates, about biside plate is individually fixed in by self-punching rivet with conducting terminal row on two cover plates.Its weak point is: install that span is large, the space hold volume is large, dielectric strength is not high between the adjacent conductive terminal board, has larger potential safety hazard.
The utility model content
The purpose of this utility model provides that a kind of insulating properties is high, good conductivity, low voltage bus bar groove that mechanical strength is large.
The purpose of this utility model is achieved in that low voltage bus bar groove, the cell body that comprises hollow, described cell body is fixedly connected to form by upper and lower cover plates and left side plate, the interval is fixed with many conducting terminal rows side by side in the cell body, be provided with the upper and lower insulating support that is connected as a single entity with cell body between the described conducting terminal row, be fixedly connected with by insulated bolt between the described conducting terminal row.
The utility model horizontal mounting means of employing as far as possible when installing and using, during construction, the number of devices required according to each power distribution station once is transported to the job site with it.Put into successively conducting terminal row on the mounted insulating support and fix upper and lower cover plates, then connect each conducting terminal row with insulated bolt.Bus duct connects and rear shell is carried out ground connection, drops at last trial run and shakes with megohmmeter and survey alternate, Relative Zero, relatively insulation resistance.Compared with prior art, the beneficial effects of the utility model are: adopted high-intensity insulating support to make insulating material, and by insulated bolt each conducting terminal row is linked into an integrated entity, its not only compact conformation, the space hold volume is little and reliable connection and alternate good insulation property that can fully guarantee conducting terminal row junction.
As further improvement of the utility model, described conducting terminal row is copper bar, and the outer surface of described copper bar has wrapped the multilayer polytetrafluoroethylarticles insulating material, the straightway of copper bar is set with gum sleeve, increase phase insulation resistance, further strengthened phase insulation, avoided short circuit.
As further improvement of the utility model, the splicing position of described copper bar is coated with one deck tin, guarantees effective contact area of junction, improves the reliability that is electrically connected.
As further improvement of the utility model, the two ends of described upper and lower cover plates extend beyond cell body and inwardly are provided with respectively bending edges, described left side plate between upper and lower cover plates and the side plate two ends outwards be provided with respectively chimb, the chimb at side plate two ends abuts in respectively on the upper and lower cover plates and by fastening bolt and is fixedly connected with cover plate, this syndeton is simple, reliable, and outward appearance is neat and artistic.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 cover plate; 101 bending edges; 2 side plates; 201 chimbs; 3 conducting terminals row; 4 insulating supports; 5 insulated bolts; 6 fastening bolts.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the cell body that comprises hollow, cell body is fixedly connected to form by upper and lower cover plates 1 and left side plate 2, the interval is fixed with many conducting terminal rows 3 side by side in the cell body, be provided with the upper and lower insulating support 4 that is connected as a single entity with cell body between the conducting terminal row 3, be fixedly connected with by insulated bolt 5 between the conducting terminal row 3.Conducting terminal row 3 is copper bar, and the outer surface of copper bar has wrapped the multilayer polytetrafluoroethylarticles insulating material, and the straightway of copper bar is set with gum sleeve, and the splicing position of copper bar is coated with one deck tin.The two ends of upper and lower cover plates 1 extend beyond cell body and inwardly are provided with respectively bending edges 101, left side plate 2 between upper and lower cover plates 1 and side plate 2 two ends outwards be provided with respectively chimb 201, the chimb 201 at side plate 2 two ends abuts in respectively on the upper and lower cover plates 1 and by fastening bolt 6 and is fixedly connected with cover plate 1.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection range of the present utility model.
