The arrangement of aluminum flat busbar
The arrangement of aluminum flat busbar affects the heat dissipation condition and mechanical strength of aluminum flat busbar.Take the rectangular aluminum flat busbar as an example, the most common arrangement is two kinds, and horizontal layout and vertical layout.
1. Horizontal layout:
The three aluminum flat busbarbars are fixed in support of insulators and have the same height.Each aluminum flat busbar can be both flat and vertical.The aluminum flat busbar with vertical horizontal layout has better heat dissipation conditions. The rated allowable current of aluminum flat busbar is larger than other placement methods, but the mechanical strength is not very good.The horizontal layout has a poor heat dissipation condition, which allows the current to be small, but the mechanical strength is high.
2. Vertical layout:
The characteristic is the three-phase aluminum flat busbar layered installation.This arrangement has a high heat dissipation and high mechanical strength and insulation ability.But vertical layout increases the height of power distribution devices and requires greater investment.
The arrangement of groove aluminum flat busbar
Each phase of a groove aluminum flat busbar is composed of two parts, and the whole section is close to the square.The channel aluminum flat busbar adopts vertical position.The structure of aluminum flat busbar is very strong and can save metal materials.
