1. A transformer, comprising:
an insulation member (10), comprising a first insulator (12), a second insulator (13), and a reference plane;
a high voltage part (20), disposed on a first side of the reference plane; and
a low voltage part (30), disposed on a second side of the reference plane,
wherein, the first insulator (12) is disposed on the reference plane, at least a portion of the second insulator (13) is located around the high voltage part (20), at least one air passage is formed by the insulation member (10), and at least a portion of the air passage is located within a height of the high voltage part (20) in a normal direction of the reference plane,
wherein a first conductive part (40) is disposed on the insulation member (10), and is located on the first side of the reference plane, and wherein the first conductive part (40) is made of a semi-conductive material.
