Heat dissipation type solid-sealed polar pole

The invention relates to a heat dissipation type solid-sealed polar pole which comprises a polar pole body and a shell, the shell is arranged outside the polar pole body in a sleeving mode and at least covers the positions of an upper wire outlet base and a vacuum arc extinguish chamber of the polar pole body, and the shell comprises a first heat dissipation shell and a second heat dissipation shell. A first mounting seat is arranged at the joint of the first heat dissipation shell and the second heat dissipation shell, a second mounting seat is arranged at the joint of the second heat dissipation shell and the first heat dissipation shell, and the first mounting seat and the second mounting seat are locked through a fastener; a liquid inlet and a liquid outlet are formed in the shell, a cooling channel is formed in the shell, and the liquid inlet and the liquid outlet are both communicated with the cooling channel. The cooling liquid can cool the pole body through the cooling channel, has the advantages of g
