Description
Technical Field
[0001] The utility model relates to the technical field of distribution boxes, in particular to a power distribution box for a substation with reciprocating air flow heat dissipation. Background Art
[0002] Distribution boxes are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets, and are the terminal equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load, and this level of equipment should provide protection, monitoring and control for the load.
[0003] Most of the existing heat dissipation devices for distribution boxes use cooling fans to achieve air exchange inside the distribution box shell. However, in this heat dissipation method, the air flow direction is fixed, which easily causes heat to accumulate at a certain place inside the distribution box. When dissipating heat inside the distribution box, it cannot effectively dissipate the heat accumulation area, thereby reducing the heat dissipation effect of the device. Content of the Utility Model

[0009] By providing a rotary air supply module, the heat generated inside the distribution box can be dissipated, improving the heat dissipation effect of the equipment.

At the same time, the rectangular mounting frame 705 is driven by the servo motor 704 to move back and forth on the outer wall of the lead screw 702, so as to evenly dissipate the heat generated inside the distribution box.
