UNIT MODULE OF BUS BAR, BUS BAR, AND BUS DUCT

摘要

Provided are a unit module of a bus bar, a bus bar, and a bus duct. A unit module of a bus bar according to the present invention has at least two bars constituting respective shapes and provided as one body. Each of the bars comprises: a conductive layer in which a high voltage high current flows; an insulation layer placed on the outer surface of the conductive layer; and a conductive heat radiating layer placed on the outer surface of a semi-conductive material layer. The conductive layer is exposed by a predetermined length from an end of each of the bars in a bar extension direction, and the insulation layer is exposed by a predetermined length from the end of each of the bars in the bar extension direction. The conductive heat radiating layer is grounded. According to the present invention, a cooling function and an insulating function can be sufficiently ensured in a high voltage and high current environment, so a bus duct can be operated with a narrow volume and a small weight. According to the present invention, installation is simple, and production costs and installation costs can be reduced.;COPYRIGHT KIPO 2017
