[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] When the distribution cabinet is installed, air vents are usually opened on its side for heat dissipation to prevent the internal temperature of the distribution cabinet from being too high and causing damage to the components. However, since hot air always flows in an upward direction and does not sink, the hot air tends to gather on the top of the distribution cabinet and cannot be completely dissipated. The heat dissipation effect is not obvious, and the heat dissipation holes can easily allow rainwater to flow into the distribution cabinet through the holes. When components come into contact with rainwater, it is easy to cause short circuits and damage, posing certain safety hazards. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a distribution cabinet for a power distribution network of an electric power system, comprising a cabinet 1, water outlets 101 are provided on both sides of the cabinet 1, heat dissipation baffles 2 are fixedly installed on both sides of the cabinet 1, and the heat dissipation baffles 2 are located vertically above the water outlets 101, a guide block 3 is fixedly installed on the top of the inner side of the cabinet 1, and the side of the guide block 3 is tightly fitted with the inner wall of the cabinet 1, and a connecting tube 4 is fixedly connected to the top of the guide block 3, and a rain shield 5 is provided on the top of the connecting tube 4, and the surface of the connecting tube 4 is fixedly connected to the top inner wall of the cabinet 1, and the interior of the connecting tube 4 is a hollow structure, and the bottom of the connecting tube 4 Located inside the guide block 3, a fixing rod 41 is fixedly installed on the inner wall of the connecting tube 4, and an exhaust fan 42 is movably connected to the top of the fixing rod 41, and an input end of the exhaust fan 42 is electrically connected to a control motor. The rain shield 5 is conical, and the diameter length of the rain shield 5 is greater than the diameter length of the connecting tube 4. A connecting frame 51 is fixedly connected to the bottom of the rain shield 5, and the bottom of the connecting frame 51 is fixedly connected to the surface of the connecting tube 4. A partition block 6 is fixedly connected to the top of the inner wall of the connecting tube 4, and the interior of the partition block 6 is a hollow structure. Air vents 601 are provided on the surface of the partition block 6, and the partition block 6 is located vertically above the exhaust fan 42.

[0023] In this embodiment, the heat generated by the internal components of the cabinet 1 rises to the inside of the guide block 3. By controlling the motor to drive the exhaust fan 42 to rotate, the hot air inside the guide block 3 is blown upward to the top of the connecting tube 4, and then passes through the partition block 6 and is discharged from the air hole 601. By installing the partition block 6, flying insects can be prevented from falling from the connecting tube 4 into the cabinet 1, and the hot air dissipates from the gap between the rain shield 5 and the connecting tube 4, thereby completing the heat dissipation of the cabinet 1. Example 2

[0025] In this embodiment, when the exhaust fan 42 blows hot air upward, the air on the outside of the cabinet 1 is sucked into the cabinet 1 through the heat dissipation baffle 2, and the air is circulated. When the air enters the cabinet 1 from the outside of the heat dissipation baffle 2, the dust in the air is filtered and isolated by the filter 1 21 to prevent the dust from entering the cabinet 1. The air enters the cabinet through the air inlet 22. Since the air inlet 22 is in an inclined state, it can prevent rainwater from entering the cabinet 1 through the air inlet 22. The rainwater slides into the water collection tank 23 and drips into the water outlet 101 through the filter 2 24 to discharge the rainwater.

[0026] The working principle of this embodiment is as follows: the control motor drives the exhaust fan 42 to rotate, and the hot air inside the guide block 3 is blown upward to the top of the connecting tube 4, and then passes through the partition block 6 and is discharged from the air vent 601. The hot air is dissipated from the gap between the rain shield 5 and the connecting tube 4 to complete the heat dissipation of the cabinet 1. When the air enters the cabinet 1 from the outside of the heat dissipation baffle 2, the dust in the air is filtered and isolated through the filter 1 21 to prevent dust from entering the cabinet 1. The air enters the cabinet through the air inlet 22, and the rainwater slides into the water collection tank 23, and drips into the water outlet 101 through the filter 2 24 to discharge the rainwater.
