Description

An inverter core with a multi-layer three-dimensional combined structure

Technical Field

The utility model relates to an inverter for a microgrid wind power generation system, in particular to an inverter core with a multi-layer three-dimensional combined structure.

Background Art

In the prior art, the heat dissipation requirement of the inverter core power device is 900w. Since the core is placed in the heat-conducting insulating liquid in the equipment barrel, the existing stabilizer inverter core is relatively large. In order to reduce the volume of the entire device, each module is designed to be very compact during manufacturing, with basically no gaps in the middle, resulting in the heat of each module being unable to dissipate into the air, resulting in very poor heat dissipation effect of the entire device. In addition, the core structure of the existing stabilizer inverter has the disadvantages of being complex and having high manufacturing costs.

Utility Model Content

In order to solve the above technical problems, the utility model provides an inverter movement with a multi-layer three-dimensional combination structure, including a plurality of copper columns arranged in a vertical ring, a screw is provided on the central axis of the plurality of copper columns arranged in a vertical ring, a support column is fixedly connected to the lower end of the screw, a filter capacitor, a surge capacitor assembly, two drive boards, a protector assembly, and a rectifier assembly are sequentially penetrated from top to bottom through the plurality of copper columns and the screw, and a transformer is provided below the rectifier assembly and is fixedly connected through the screw.

Specifically, a current sensor is provided on the copper column above the filter capacitor, a handle is provided on the upper end of the screw rod, and insulators are connected to the upper ends of the plurality of copper columns.

The beneficial effect of the utility model is that the utility model adopts a multi-layer three-dimensional structure movement, in which the copper column is both a conductive conductor and a movement structure support, and is also a terminal for external electrical connection. The three-dimensional structure movement placed in the liquid not only meets the heat dissipation requirements of the movement but also greatly reduces the size of the equipment and greatly saves manufacturing costs.
