Description

High-current sleeved conducting rod

The utility model belongs to transformer device, is a kind of big current carrying object one big electric current sleeve pipe conducting rod that is used for big capacity transformation electric current sleeve pipe.

General big electric current casing current ampacity is all at 8000 amperes to 25000 amperes even bigger, and big electric current sleeve pipe is the power station, and the transformer device that lead-in wire sealing and the enclosed busbar of drawing from generating set link to each other with the transformer low voltage outlet is realized in the power plant.Main body-the conducting rod of present big electric current sleeve pipe conduction adopts an integral metal material to be processed into, and amount of machining is big, and stock utilization is low, and production efficiency is low, the cost height.

The purpose of this utility model is to provide a kind of processing easy, the stock utilization height, and lower-cost big electric current sleeve pipe conducting rod structure, it is applicable in big electric current sleeve pipe does big current carrying object.

Because the current-carrying of big electric current sleeve pipe load is big, the loss of sleeve pipe and the resistance of electric conductor are directly proportional, with square being directly proportional by electric current, therefore, each element that big electric current sleeve pipe conducting rod constitutes itself needs enough conductive sections, excellent conducting performance and radiating condition are to guarantee the fail safe and the reliability of big electric current sleeve pipe operation.

According to above-mentioned requirements, the purpose of this utility model realizes by following measure: the main body contact rod of big electric current sleeve pipe conducting rod is a root electric conductivity good metal rod, one end of rod is processed into one group of fin, the outer end of fin is welded with backplate, the both sides of fin are welded with conductive plate, other end process and assemble bevel for welding at contact rod, the earthing bonding wire connects with flange, the other end welding conductive plate of flange, two groups are processed with the air vent that is mutually 90 ° on the flange, also are processed with a cannelure on contact rod; Main body-the contact rod of big electric current sleeve pipe conducting rod can also be combined by electric conductivity good hollow metal pipe and garden shape metal bar, metal bar is processed into hollow element, one end of hollow pipe and garden shape metallic plate are welded into blind end, the outside connects with flange by bonding wire, the other end of hollow pipe is welded as a whole with the gelled hollow pipe fitting of processing, is processed with one group of oil guiding hole on hollow pipe.This lightweight construction, radiating condition is good, is more suitable for the high big electric current sleeve pipe of ampacity.

Embodiment of the present utility model can further describe with following accompanying drawing.

Fig. 1 is concrete structure figure of the present utility model.

Fig. 2 is an another kind of structure chart of the present utility model.

With reference to Fig. 1, the utility model is by conductive plate 1, flange 3, contact rod 5, fin 8, backplate 9 is formed, wherein, one end of contact rod 5 is processed into fin 8, and the both sides of fin 8 are welded with conductive plate 7, and backplate 9 is welded on the outer end of fin 8, the other end of contact rod 5 connects with flange 3 by bonding wire 4, conductive plate 1 is welded on the other end of flange 3, is processed with two groups of air vents 2 that are mutually 90 ° on the flange 3, also is processed with cannelure 6 on contact rod 5.

With reference to Fig. 2, another kind of structure of the present utility model is that contact rod is by hollow pipe 14, combine with garden shape metallic plate 10 and hollow pipe fitting 13, wherein an end inwall of hollow pipe 14 is welded into blind end by bonding wire 4 and garden shape metallic plate 10, the outer wall of hollow pipe 14 connects with flange 3 by bonding wire 4, conductive plate 1 is welded on the other end of flange 3, be processed with two groups of air vents 2 that are mutually 90 ° on the flange 3, on hollow pipe 14, be processed with one group of oil guiding hole 11, the other end of hollow pipe 14 connects with hollow pipe fitting 13 by bonding wire 12, hollow pipe fitting 13 other ends are processed with fin 8, through hole 15 is processed in the centre, the both sides of fin 8 are welded with conductive plate 7, and backplate 9 is welded on the outer end of fin 8, also are processed with cannelure 6 on hollow pipe 14.

It is good to the utlity model has electric property, process easy, the characteristics that process costs is low.
