Fully-insulation tube bus bar

Abstract

The invention discloses a fully-insulation tube bus bar, which comprises a tubular conductor. The surface of the tubular conductor is wrapped by an inner insulating layer. The surface of the inner insulating layer is coated with a shielding layer, and the surface of the shielding layer is coated with a heat dissipation layer. The surface of the heat dissipation layer is wrapped with an outer insulating layer. The surface of the outer insulating layer is wrapped with an outer protection sleeve. Color code grooves are formed in the outer surface of the outer protection sleeve in the surrounding mode. A color code layer is arranged on the inner surface of each color code groove. Grooves with semicircular sections are equidistantly formed in the outer surface of the outer insulating layer. Convex strips matched with the grooves are integrally formed on the inner surface of the outer protective sleeve in the equal-distance manner. According to the technical scheme of the invention, heat dissipation grooves are formed in the heat dissipation layer and foam sponge fillings are filled in the heat dissipation grooves. Therefore, the heat radiated by the tubular conductor can be absorbed by the foam sponge fillings, and then is discharged to the outside through heat dissipation circular holes. Therefore, the heat dissipation performance of the fully-insulation tube bus bar is improved. Meanwhile, the use stability of the fully-insulation tube bus bar is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a fully insulated tube busbar. Background technique [0002] With the rapid development of my country's economy, the demand for electricity in the whole society is increasing day by day. At present, the low-voltage side of 110kV and 220KV substations adopts 10kV and 35kV voltage levels. With the increase of the main transformer capacity, the rated current of the incoming line side of the low-voltage side of the transformer is also increasing, so the usage of the bus is also increasing. The larger, the bus (bus line) refers to the copper with high conductivity ( Copper row ), made of aluminum material for transmission electrical energy , a product with the ability to collect and distribute power, is the main wire used to transmit electric energy in a power station or substation. Through it, the generator, transformer or rectifier output power tr...
