The heat conduction groove is rectangular, the heat conduction groove is vertical and runs through apron bottom surface both ends, and the both ends of heat conduction groove are equipped with the long-pending silo, and the heat conduction groove communicates with the inside of busbar shell, increases the area of contact of apron and the inside of busbar shell through the heat conduction groove to the heat dissipation efficiency is improved to the variable phase increase heat conduction area, and the long-pending silo is then in order to assist the fixed convenient heat transfer of pouring the layer.

The material of pouring the layer is heat conduction material, and the pouring layer is filled in the clearance between apron and curb plate in a sufficient way, and the layer of pouring is filled and is established in the heat conduction inslot, through the layer of pouring that can transfer heat, can not only do the inside pouring filler of bus duct and can also assist the heat transfer, convenient heat dissipation.

The beneficial effects are that:

the wire row and the ground wire row which are all arranged transversely and in parallel originally are changed in discharge positions, the transverse quantity on the wire row is reduced, so that the quantity of heating sources is reduced, heat transfer is facilitated, the contact area between a pouring layer and a cover plate is increased through the heat conducting grooves, and the heat dissipation area is increased, so that the heat dissipation efficiency is improved.

The quantity of heating units on a single transverse surface is reduced through the wire rows which are vertically arranged, so that heat transfer is facilitated, and the ground wire rows in the middle can also play a role in assisting all wires in heat removal.

The contact area between the cover plate and the inside of the bus shell is increased through the heat conducting grooves, so that the heat conducting area is increased in a phase-changing mode to improve the heat dissipation efficiency, and the material accumulating groove is used for assisting in fixing the pouring layer and facilitating heat transfer.

The pouring layer capable of transferring heat can be used as pouring filler in the bus duct, heat transfer can be assisted, and heat dissipation is facilitated.
