Abstract

This utility model discloses a heat dissipation structure for a current transformer, including a current transformer body. A first fixing box is fixedly installed at the top of the current transformer body. An air supply component is arranged inside the first fixing box. Multiple air inlets are opened on both sides of the first fixing box, and filter components are fixedly installed at the air inlets. A second fixing box is fixedly installed at the bottom of the current transformer body. An exhaust component is fixedly installed inside the second fixing box. An air duct is opened inside the current transformer body. This utility model achieves rapid air flow inside the current transformer by setting the air supply component inside the first fixing box and the exhaust component inside the second fixing box. The air supply component and the exhaust component are connected to the air duct inside the current transformer body, thereby realizing the heat dissipation of the current transformer and ensuring the heat dissipation effect of the current transformer.
