Abstract

The invention discloses a dense-type bus duct. The dense-type bus duct comprises two flange-type cooling fins, side aluminum plates, copper busbars and insulative adhesive tapes, wherein the two flange-type cooling fins are mutually connected, the side aluminum plates are arranged at two ends of each flange-type cooling fin, the copper busbars are arranged in the flange-type cooling fins, the insulative adhesive tapes are arranged between end portions of the flange-type cooling fins and the side aluminium plates, and the two flange-type cooling fins are fixed through screws. The problem of heat dissipation of the bus duct is well solved, and carrying capacity of a copper bus is enabled to achieve the maximum value when the copper bus is under the same standard. Besides, temperature rise preferably meets relative requirements of government standards when the bus duct works within a current-carrying range, so the aims of saving raw materials such as the copper bus, conserving energy and protecting the environment are achieved.

Description

technical field [0001] The invention relates to a dense busway. Background technique [0002] The 0.4kV intensive busway has been widely used in power supply and distribution systems. Due to its special structural requirements, usually due to the limited use environment, it must be small in size. However, the existing products cannot solve the problem of heat dissipation due to the limited volume of the aluminum profile shell. This problem can only be solved by increasing the specification of the circuit busbar. Contents of the invention [0003] The main purpose of the present invention is to provide an intensive bus duct with good heat dissipation effect, energy saving and environmental protection. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: a dense busway, including two flange-type heat sinks connected to each other, and side aluminum plates arranged at both ends of the two flange-type heat sinks, and a...
