Description
Technical field
The utility model relates to a kind of common box bus bridges.
Background technique
Currently, power plant, industrial and mining enterprises pressure, match, in power supply system, generator lead-out wire to main transformer, main transformer pressure
The current supply circuit that electric energy is conveyed between device and high voltage power distributing cabinet, high voltage power distributing cabinet generallys use common box bus bridge, its main feature is that electric
Energy transmission capacity is big, good insulation preformance, high safety and reliability, container body of outer cover are rigidly good, intensity is big, bearing capacity is strong etc..For
Common box bus bridge size between high-current switch is larger, and the busbar weight in bus bridge is big, in order to guarantee common box bus bridge
Intensity, bus bridge is assembled frequently with steel plate.But because steel plate is magnetic material, when bus is powered, bus-bars conductor occurs
Electromagnetic induction, steel shell is interior to form closed magnetic circuit, and steel shell cuts alternate magnetic force line and generates vortex inside housings, makes
Its interior atoms high speed random motion, atom collides with each other, rubs and generates thermal energy, so that metallic conductor be caused to rise
Temperature, the situation for causing bus bridge local temperature rise excessive.
Utility model content
A kind of common box bus bridge for high, anti-vortex that the purpose of this utility model is to provide structural strengths.
To achieve the above object, the technical solution of the common box bus bridge of the utility model is:
A kind of common box bus bridge includes the shell being spliced, and the enclosure interior is equipped with to be extended along shell length direction
Passing channel, at least part uses the non-magnetic material for running through shell length direction both ends on at least partly panel of shell.
The beneficial effect is that: the bus bridge of the utility model non magnetic material of local use on the basis of steel bus bridge
Material under the premise of ensure that bus bridge integral strength, avoids the generation being vortexed in bus bridge operation well, improves transmission & distribution
Electrical efficiency.
Specifically, one of panel of shell uses non-magnetic material.While convenient for setting, facilitate further
Reduce vortex.
Further, the both ends of the length direction of each panel of shell are respectively connected with for installing insulator or wire clamp
Frid is non-magnetic material with the frid for using the panel of non-magnetic material to connect.Frid is set and frid is non-magnetic material
Facilitate to prevent from forming closed magnetic circuit between frid while being easily installed insulator or wire clamp.
Further, the shell is cubic shell, and the panel using non-magnetic material is the upper surface of cubic shell plate.It is non-
The most intensity of magnetic material is low, and the upper surface of not load-bearing plate anti-using non-magnetic material vortex while helps to enhance the strong of shell
Degree.
Further, the non-magnetic material is aluminium sheet.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment one of the common box bus bridge of the utility model；
Fig. 2 be Fig. 1 in the upper surface of plate structural schematic diagram；
Fig. 3 is the structural schematic diagram of the frid in Fig. 1；
In attached drawing: 1, heat sink；2, side panel；3, top panel；4, bottom plate；5, frid.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment one of the common box bus bridge of the utility model, as shown in Figure 1 to Figure 3, including shell, shell four
Square shell, cubic shell include side panel 2, top panel 3, bottom plate 4, frid 5 and heat sink 1, cubic shell by side panel 2,
Top panel 3, bottom plate 4, frid 5 are spliced.Shell penetrates through at the both ends of length direction, is equipped with insulator or line on frid 5
It presss from both sides, the bus extended along shell length direction is fixedly connected on insulator or wire clamp.
Side panel 2 and bottom plate 4 in the present embodiment are cold-rolled steel sheet, and the purpose designed in this way is to guarantee shell
Rigidity.Top panel 3 is non magnetic plate, and the non magnetic plate in the present embodiment is aluminium sheet, certainly, non magnetic in other embodiments
Plate is also possible to aluminium alloy plate or stainless steel plate etc..When due to being powered, electromagnetic induction occurs for electrical conductor in bus bar, and metal is cut
It cuts alternate magnetic force line and generates vortex in metal inside, the atom high speed random motion for keeping it internal, atom collides with each other, rubs
It wipes and generates thermal energy, it is bigger than normal to will cause bus axle housing local temperature rise.Top panel 3 uses non-magnetic material, and shell is not formed and closed
Magnetic circuit to be closed, the generation being vortexed in bus bridge operation is effectively prevented, operation is safer, and the operation troubles of bus bridge substantially reduces,
Increase the service life of bus bridge；And because of the aluminium sheet for only having top panel 3 low using structural strength in shell, to entire shell
The structural strength of body influences smaller.
For the ease of installation insulator or wire clamp, each panel of shell is even connected to frid 5 at the both ends of length direction, absolutely
Edge or wire clamp are mounted in frid 5.Shell forms closed magnetic circuit in order to prevent, and the frid 5 connecting with top panel 3 is aluminium sheet,
Certainly, non magnetic plate is also possible to aluminium alloy plate or stainless steel plate etc. in other embodiments.
In order to enhance the utility model bus bridge heat dissipation performance, heat sink 1 is installed on two side panels 2, is radiated
There are multiple perforative heat release holes, the heat sink 1 in the present embodiment is made using steel plate on plate 1.
The specific embodiment two of the common box bus bridge of the utility model, together the difference of case bus bridge specific embodiment one it
It is in plate includes using strip made of non-magnetic material and the steel plate with strip splicing, length the upper surface of in the present embodiment
Item runs through the both ends in shell length direction.Other are the same as example 1, and repeat no more.
The specific embodiment three of the common box bus bridge of the utility model, together the difference of case bus bridge specific embodiment one it
It is at least one of two side panels of shell in the present embodiment are made using non-magnetic material.
The specific embodiment four of the common box bus bridge of the utility model, together the difference of case bus bridge specific embodiment three it
It is in the side panel in the present embodiment includes using strip made of non-magnetic material and the steel plate with strip splicing, length
Item runs through the both ends in shell length direction.
