Abstract
The utility model discloses a structure for reducing contact voltage-drop. 3 to 12 layers of copper sheets are horizontally laid in a stacked manner on the two sides of a vertical post bus on the contact surfaces which require to be bonded by high-current short-circuiting switches, steel plates are respectively arranged at the two ends of the copper sheets, holes are formed on the two ends of the steel plates, the steel plates are connected through double-ended bolts penetrating the holes, and nuts are screwed on the two ends of the bolts. A group of thin copper sheets with good conductive property and yielding property are cushioned between the high-current short-circuiting switches and the vertical post bus, therefore the surfaces of the switch bonding head and the vertical post bus can better contact with the copper sheet, that is, the effective contact area is increased, and the contact voltage-drop on the surfaces of the high-current short-circuiting switch bonding head and the vertical post bus can be effectively reduced. The structure has the characteristics that the assembly and the disassembly are convenient, and the structure can be reused.
Description
Technical field
The utility model relates to a kind of structure that reduces voltage drop of compression joint surface, belongs to the interconnection technique field of Aluminum Electrolysis Production central post bus.
Background technology
Open and close down in the device of electrolyzer not having a power failure, all be provided with two big short circuit current switches on each riser bus bar, these two big short circuit current switch one ends directly are crimped on the riser bus bar, and the other end is connected on the short-circuit block by soft bus.Crimping between big short circuit current switch and the riser bus bar is subjected to the influence of short circuiting switch bonding head surface and riser bus bar surface finish, and crimping is bad, can produce bigger volts lost in crimping place, and Gao Shike reaches 90mv.If the crimping volts lost between big short circuit current switch and the riser bus bar is higher, will influence the fractional flow of big short circuit current switch, thereby not having a power failure, influence do not open and closes down the result of use of electrolyzer short circuiting device.
The utility model content
The purpose of this utility model is: the structure that a kind of simple in structure, easy installation and removal, reusable reduction voltage drop of compression joint surface are provided, with the crimping volts lost between big short circuit current switch of effective reduction and the riser bus bar, thereby the crimping volts lost between big short circuit current switch and the riser bus bar is remained in the specialized range, open or close down the normal operation of electrolytic cell assembly to guarantee not have a power failure.
The utility model is achieved in that this structure comprises riser bus bar, need in the riser bus bar both sides that stacked respectively tiling has 3～12 layers of copper sheet on the crimping face of the big short circuit current switch of crimping, the copper sheet two ends of both sides are respectively equipped with steel plate, the two ends of steel plate are porose, the threaded stud of steel plate in being through the hole connects, and the two ends of bolt are screwed with nut.
In the structure of above-mentioned reduction voltage drop of compression joint surface, described copper sheet thickness is 0.8～1.2mm, and the width of copper sheet is corresponding with the width of riser bus bar, and the length of copper sheet is than the width of long two steel plates of crimping face length degree of big short circuit current switch.
Compared with prior art, prior art directly is crimped on big short circuit current switch on the riser bus bar, owing to be subjected to the influence of big short circuit current switch bonding head surface and riser bus bar surface finish, contact is bad after the crimping, can produce bigger volts lost in crimping place, Gao Shike reaches 90mv.The utility model between big short circuit current switch and riser bus bar cushioning one group conduct electricity very well, yielding thin copper sheet, switch bonding head surface can well be contacted with copper sheet respectively with the riser bus bar surface, be equivalent to increase effective contact area, so can effectively reduce the crimping volts lost on big short circuit current switch bonding head surface and riser bus bar surface.And has easy installation and removal, reusable characteristics.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Being labeled as in the accompanying drawing: 1-riser bus bar, 2-copper sheet, 3-steel plate, 4-bolt, 5-nut, the crimping face that 6-is formed by copper sheet.
Embodiment
Embodiment of the present utility model: the structure of reduction voltage drop of compression joint surface of the present utility model as shown in Figure 1, during enforcement, need stacked respectively tiling on the crimping face of the big short circuit current switch of crimping that the copper sheet 2 of 10 layers of 400mm * 420mm * 1mm is arranged in existing riser bus bar 1 both sides, copper sheet 2 two ends of both sides are respectively equipped with the steel plate 3 of 520mm * 40mm * 15mm, there are φ 18 holes at the two ends of steel plate 3, the threaded stud 4 of the M16 of steel plate 3 in being through the hole connects, and the two ends of bolt 4 are screwed with nut 5.
Because the utility model is needing 10 layers of copper sheet 2 of the riser bus bar both sides first crimping of difference of the big short circuit current switch of crimping, utilize the high conduction performance of copper sheet 2 and good deformation characteristic, the crimping plane of big short circuit current switch is closely contacted with the crimping plane of riser bus bar 1 by copper sheet 2, increase effective contact area, reached the purpose that reduces contact drop between high-current switch and the riser bus bar.
When using the utility model, preparing to open or close down the electrolyzer specific operation process is such, before big short circuit current switch is installed, the first copper sheet 2 of stacked 10 layers of 400mm * 420mm * 1mm of tiling respectively in riser bus bar both sides that needs are installed the big short circuit current switch position, the steel plate 3 that has a 520mm * 40mm * 15mm in φ 18 holes with two two ends is pushed down copper sheet 2 one ends of riser bus bar 1 both sides respectively then, bolt 4 with the screwed M16 in two ends, pass the hole at both sides steel plate 3 two ends respectively, bolt 4 two ends nut screwing clampings compress by steel plate 3 and bolt 4 copper sheet 2 with riser bus bar 1 both sides; Then copper sheet 2 thread of both sides is stretched exhibition, the other end that uses the same method copper sheet 2 also clamps; Just formed a crimping face 6 that constitutes by copper sheet like this in the both sides of riser bus bar 1; And then relative the leaning against on the crimping face 6 that is formed by copper sheet of crimping face of two big short circuit current switches compressed with bolt.
