Abstract
The invention discloses a kind of busbar bridging methods, comprising the following steps: a) to needing the faying surface for carrying out overlapped primary and secondary busbar to be embossed, bottoming hole is gone out on secondary busbar, and clear up the faying surface of primary and secondary busbar；B) welding tin piece is cut according to the size of faying surface and be placed on lap-joint, and be clamped fixation with stationary fixture；C) welding tin piece is heated to tin piece fusion temperature with welding gun；D) tin that overflows is removed, stationary fixture is removed.Above method process is simple, easy to operate, is welded using welding tin piece to primary and secondary busbar, so that the connection between primary and secondary busbar is stronger, stablizes, efficiently solves the problems, such as that contact resistance is excessive between busbar connection.
Description
Technical field
The invention belongs to technical field of electricity, and in particular to the busbar bridging method in a kind of power distribution cabinet.
Background technique
Busbar (copper bar, aluminium row) is mainly used in power distribution cabinet the always connection of system switch and the switch in each shunt circuit.It is existing
Have in technology, the connection of busbar is generally used the mode of bolt fastening, connects usually using the zinc-plated fastening bolt of steel, even
It needs to tighten according to the permission Tightening moment of bolt when connecing, there is not allowed that slipping phenomenon or damage coating phenomenon.In fastening, spiral shell
Mother cannot twist too tight or too loose, and tightness is answered moderate.If crossing pine, contact resistance is excessive；If tension, busbar junction
Applanation is uneven, can make the deformation of busbar contact site so that contact resistance is excessive after heated.Due to in-site installation environment etc. because
Element, tightening for nut is completed by manually in busbar connection procedure, this is difficult to guarantee that the tightness of nut is moderate, often
There is the case where excessive contact resistance or even damage busbar.
Goal of the invention
The object of the present invention is to provide a kind of busbar bridging methods, make between busbar while reducing operation difficulty
It connects more stable.
To achieve the above object, the technical scheme is that a kind of busbar bridging method, comprising the following steps:
A) to needing the faying surface for carrying out overlapped primary and secondary busbar to be embossed, bottoming hole is gone out on secondary busbar, and right
The faying surface of primary and secondary busbar is cleared up；
B) welding tin piece is cut according to the size of faying surface and be placed on lap-joint, and be clamped fixation with stationary fixture；
C) welding tin piece is heated to tin piece fusion temperature with welding gun；
D) tin that overflows is removed, stationary fixture is removed.
Above method process is simple, easy to operate, is welded using welding tin piece to primary and secondary busbar, so that primary and secondary is female
Connection between row is stronger, stable, efficiently solves the problems, such as that contact resistance is excessive between busbar connection.
Detailed description of the invention
Fig. 1 is the schematic diagram of primary and secondary busbar of the present invention；
Fig. 2,3 are present invention overlap joint status diagrams；
Fig. 4 is the partial enlarged view of Fig. 2.
Specific embodiment
Invention is further explained with reference to the accompanying drawing.
A kind of busbar bridging method, comprising the following steps:
A) to needing the faying surface for carrying out overlapped primary and secondary busbar 10,20 to be embossed, heating is gone out on secondary busbar 20
Hole 21, and the faying surface of primary and secondary busbar 10,20 is cleared up；
B) welding tin piece 30 is cut according to the size of faying surface and be placed on lap-joint, and be clamped admittedly with stationary fixture 40
It is fixed；
C) welding tin piece 30 is heated to tin piece fusion temperature with welding gun；
D) tin that overflows is removed, stationary fixture 40 is removed.
When it is implemented, be embossed with bus bar processing machine to primary and secondary busbar 10,20 and punching, then to faying surface into
Row cleaning, to remove the impurity such as the greasy dirt adhered on faying surface, dust, it is ensured that faying surface is neatly clean；Then welding is placed
Tin piece 30 is simultaneously bonded the faying surface of primary and secondary busbar 10,20, clamps primary and secondary busbar 10,20 with stationary fixture 40, and make to take
Socket part position is exposed；Then the overlapping part of primary and secondary busbar 10,20 is resisted with welding gun, heating welding tin piece 30 simultaneously makes its fusing；Most
After clean up excessive tin, remove stationary fixture 40.
Above-mentioned steps operation is fairly simple, will not damage to primary and secondary busbar 10,20 in whole process.Pass through embossing
Processing and tin piece welding mode make the fitting between primary and secondary busbar 10,20 even closer, effectively prevent due to master,
Secondary busbar 10,20 is not connected firmly the phenomenon for causing contact resistance excessive.
Preferably, in the step a) bottoming hole 21 be evenly arranged on the faying surface of secondary busbar 20 it is multiple.Specific implementation
When, the number of bottoming hole 21 can be selected according to the size of faying surface, to guarantee to weld the heated uniformity of tin piece 30；This
Outside, 21 aperture of bottoming hole is smaller, will not thus impact to secondary busbar 20.
Preferably, the soldering tip of welding gun is connect by the bottoming hole 21 on time busbar 20 with welding tin piece 30 in the step c)
Touching, soldering tip is cylindrical, and outer diameter matches with the internal diameter of bottoming hole 21.By the soldering tip of welding gun by bottoming hole 21 directly with weldering
The contact of tin piece 30 is connect, welding tin piece 30 can directly be heated, not need to transfer heat to welding tin by busbar
Piece 30 effectively prevents high temperature to damage caused by primary and secondary busbar 10,20.
