A dense busway

Abstract

The invention discloses a dense busway, which comprises a plurality of single-phase busbar bodies and a plurality of first supports, and each single-phase busbar body comprises a metal shell, one or more conductors packaged in the shell, and covered in The insulating layer on the periphery of each piece of conductor is completely closed to the outside world. The shell of the single-phase busbar body includes the body part, the bending part extending from the two ends of the body part, the heat sink extending from the middle part of the body part and the two sides of the shell. End-closed cover plate, radiators are symmetrically distributed on both sides of the main body, the first support is assembled between two adjacent unidirectional busbar bodies to combine multiple single-phase busbar bodies into a row to form a multi-phase For the busway, the first supporting piece is respectively fixed on the radiators of the single-phase busbar body on the left and right sides through a plurality of fixing pieces, and the two adjacent radiators on the same side on the same single-phase busbar body cooperate with each other to hold and fix pieces. The invention has strong heat dissipation, small power loss and high safety performance.

Description

technical field [0001] The present invention relates to a dense bus duct, more particularly, the present invention relates to a dense bus duct for transmitting medium and high voltage power. Background technique [0002] With the rapid development of the city, there are more and more high-rise buildings, and the electricity load of the buildings increases sharply. The original wires and cables have been gradually replaced by large-capacity cables due to their small capacity, inconvenient branches, and inconvenient cluster management. , The branch is convenient, the cluster management is convenient to replace the bus duct. Busway is widely used in key projects such as power transmission trunk lines of fire fighting equipment and fire emergency equipment trunk lines, such as hotels, airports, subways and other important projects. Therefore, the safety and stability of busway products are very important. [0003] However, bus ducts also have some disadvantages. For example, be...

Problems solved by technology

[0007] However, the above existing technologies all have the problems of poor heat dissipation, high consumption of copper resources, large power loss, and poor safety performance, which cannot meet the requirements of medium and high voltage transmission lines

[0008] Therefore, providing a dense bus duct with strong heat dissipation, low power loss and high safety performance has become a problem to be solved in the industry
