Problems solved by technology

[0004] Excessive temperature and overheating of the busbar will cause insulation aging or even burn insulation materials, resulting in short-circuit faults and major economic losses
The contact resistance at the joint will increase due to the increase in temperature, resulting in a vicious circle

Embodiment Construction

[0015] As shown in the drawings, a busbar with heat dissipation function includes a busbar conductor 1, and the outside of the busbar conductor 1 is coated with a radiation heat dissipation paint, and the radiation heat dissipation paint forms a heat dissipation layer 2 of the busbar.

[0016] The appropriate thickness of special heat-dissipating paint should be painted on the appropriate position of the bus conductor 1. The painting position should have a large heat-dissipating space, and it should not be the surface of the conductor near and opposite. Be even.

[0017] The radiation heat dissipation coating can form an effective heat insulation barrier, so as to achieve the effect of cooling and heat insulation. It emits the heat on the bus conductor in the form of 8-13.5μm wavelength.

[0018] The cooling range of the busbar is shown in the table below:

[0019] Bus base

[0020] The above embodiments do not limit the present invention in any way, and all technic...

Abstract

The invention discloses a bus with a heat radiation function, which comprises a bus conductor (1), wherein a heat radiation layer (2) which is formed by heat radiation coating is coated on the outer part of the bus conductor (1), and the heat radiation coating forming the heat radiation layer (2) is formed by a nanometer material having high visible light and near infrared reflection rate, high thermal infrared transmission rate, high temperature stability, good physical performance, good chemical performance and good construction performance, so the high-efficient radiation temperature reduction and heat insulation can be realized.

Description

technical field [0001] The invention relates to a busbar, in particular to a busbar capable of realizing the function of cooling and heat insulation, and belongs to the technical field of high-current switchgear. Background technique [0002] The bus bar refers to the connection of voltage distribution devices at all levels in the substation, as well as the connection of electrical equipment such as transformers and corresponding power distribution devices. Most of them use bare or stranded wires with rectangular or circular cross-sections, which are collectively called bus bars. The role of the bus is to collect, distribute and transmit electrical energy. [0003] Busbars exposed outdoors are often eroded by wind, rain, snow, sun, freezing, etc. These factors will accelerate the oxidation and corrosion of busbar joints, which will increase the contact resistance of the joints and increase the temperature of the busbar during operation. . [0004] Excessive temperature and...
