[0002] A frequency conversion cabinet is a power control device that applies frequency conversion technology and microelectronics technology to control an alternating current motor by changing the working power frequency of the motor. It has functions such as speed regulation, energy saving, soft start, protection, and improvement of power grid quality, and is widely used in the field of industrial automation control.

[0003] The frequency conversion cabinet adopts a modular design concept, making each functional module relatively independent, facilitating production, installation, and maintenance. The overall structure is compact, occupying a small area, and is convenient for installation and use in a limited space. It is internally provided with a ventilation and heat dissipation system to ensure that the frequency converter and other key components maintain good heat dissipation performance during long-term operation.

[0004] The electronic components installed inside the traditional frequency conversion cabinet are connected by wires, and the installation method of the internal electronic components is to select the installation position according to the performance between each electronic component. However, when installing according to the performance between the electronic components installed inside the frequency conversion cabinet, there will be a messy arrangement of wires when using wires for connection, which will cause the staff to spend a lot of time looking for wires and interfaces during maintenance or repair, thus making it difficult to maintain the frequency conversion cabinet. Therefore, it does not meet the existing requirements, and for this reason, we propose a frequency conversion cabinet with a new layout method. Content of the Utility Model
