[0002] The distribution cabinet is a general term for the motor control center. The full name of reactive compensation is power compensation. It is a technology that can reduce the loss of power supply transformers and transmission lines, improve power supply efficiency, and improve the power supply environment. Therefore, when using the distribution cabinet, a low-voltage reactive compensation distribution box with reactive compensation technology can be used. The distribution cabinet has very high temperature requirements. When the internal temperature of the distribution cabinet exceeds 70 degrees, it is easy to cause failure of the distribution cabinet. Therefore, the distribution cabinet needs to be cooled.

[0003] In order to solve the above problems, patent CN202211289167.5 discloses a low-voltage reactive compensation distribution cabinet. The distribution box is provided with a cooling mechanism for dissipating the heat of the distribution box. By starting the fan, the air in the distribution box can be kept circulating, thereby achieving the purpose of dissipating the heat of the distribution box.

[0004] The following problems still exist during the implementation process: the fan installed in the distribution box will generate a lot of heat when running, which is not conducive to efficient heat dissipation of the distribution box; in addition, when installing the reactive compensation device in the distribution cabinet, due to the small internal space of the distribution cabinet, it takes a lot of time for the operator to install and disassemble during installation and disassembly, which not only increases the installation and disassembly time, but also increases the physical labor of the operator, causing inconvenience to use.

[0005] For this reason, we propose an integrated reactive power compensation device for integrated power distribution cabinets to solve the above problems. Utility Model Content
