The PTC drive unit has a function of generating cold air on one side and generating heat on the other side in accordance with the supply direction of the DC voltage and is provided between the bottom surface of the insulator and the upper surface of the insulator fixed body, (PTC) that is driven and generates cool air through the insulator to prevent overheating of the bus bar, and monitoring data on various components including temperature change data of the bus bar installed in the busbars, And a built-in server that outputs the data when the microcomputer requests the data.

However, when the high voltage current flows, the bus bar is overheated due to the exothermic phenomenon, and the electric conductivity is lowered due to the nature of the electric field drawn in the concentric circle, so that the voltage becomes unstable.
