Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box which is convenient for heat dissipation. Background Art

[0002] The distribution box is a key mechanism for modern power transmission. It is used to assemble electrical appliances for power distribution, so that electric energy can be distributed to lower-level distribution equipment in different locations, ensuring the reasonable distribution and output of power between power facilities. It is widely used in industries, commerce, energy management and other fields.

[0003] In order to ensure that the components installed in the distribution box can work normally, it is usually necessary to dissipate heat from the distribution box. The existing heat dissipation method is usually to set vents on the side of the box for ventilation and heat dissipation, but this method has low heat dissipation efficiency, and the heat generated by high-power components such as SVG in the box is much greater than the ventilation volume, which will cause uneven heat dissipation in the distribution box, thereby affecting the overall working efficiency of the equipment.

[0004] Therefore, it is necessary to invent a distribution box that is easy to dissipate heat to solve the above problems. Utility Model Content

[0034] During the use of the equipment, the temperature sensor 15 monitors the temperature inside the distribution box 1 in real time. When the monitored temperature reaches the threshold, the motor 24 is started through the controller 21. The output end of the motor 24 drives the heat dissipation fan blades 25 to rotate, and the hot air is sucked outward through the first exhaust box 11 and the second exhaust box 12, so as to dissipate the heat inside the distribution box 1 and improve the heat dissipation efficiency.
