High-voltage bushing and high-voltage power transmission system

A high-voltage bushing, comprising:

• a conductive rod having an air channel therein, the air channel including an air inlet and an air outlet;
• and
• an air cooling device including at least one fan, the fan being configured to output air flow, so as to blow the air flow into the air channel through the air inlet;
• wherein the air channel further includes an air inlet channel and an air outlet channel, wherein a first end of the air inlet channel and a first end of the air outlet channel are located at a first end of the conductive rod;
• the air inlet is located at the first end of the air inlet channel, and the air outlet is located at the first end of the air outlet channel;
• and a second end of the air inlet channel and a second end of the air outlet channel communicate with each other at a position that is in the conductive rod and is adjacent to a second end of the conductive rod;
• the conductive rod includes a conductive rod body in a hollow structure, and an air cooling pipe disposed in the conductive rod body and extending in an axial direction of the conductive rod body;
• and a space inside the air cooling pipe forms the air inlet channel, and a space between an outer wall of the air cooling pipe and an inner wall of the conductive rod body forms the air outlet channel;
• and
• the conductive rod includes at least one support portion disposed in the air outlet channel, and the at least one support portion is clamped between the outer wall of the air cooling pipe and the inner wall of the conductive rod body.
