Connected using copper product built-up welding.
The length of the tooth connection is 1~1.2 times of the rectangle hollow copper busbar section outline height.
The utility model is according to when alternating current is by conductor, and electric current will concentrate mainly on conductive surface and flow through, rather than
It is evenly distributed in the kelvin effect presented in whole cross-sectional area of conductor and designs, its outstanding feature possessed and marked improvement is specific
Show the following aspects：
1st, busbar weight is light, is reasonably distributed by the alternating current in conductor, reduces conductor kelvin effect and bus is carried
The influence of flow, busbar carrying capacity is big, saves copper material usage amount；
2nd, connection uses bus transition section between bus, and even dual mode, junction conductor are fixedly connected with welding using spiral shell
Effective conductive section is big, and caloric value is small, high mechanical strength；
3rd, busbar branches inlet wire copper bar, outlet copper bar and bus are easy to connect, and junction contact area increases 1 times, connection
Locate high mechanical strength, caloric value reduces, and can slow down the insulation ag(e)ing of supporting bus insulating element；
4th, the flow-guiding radiation hole that bus roof and bottom wall are uniformly opened up has wind-drawing effect, and bus good heat dissipation effect improves
Bus run condition.
It is the engineering actual demand in the range of 2000A~8000A that the utility model, which meets busbar carrying capacity, improves electricity
Machine pressure bus, the mesolow distribution of transformer station of the machine pressure bus of thermal power plant generator, hydropower generator in Force system
The security reliability of device bus run.
