The utility model provides an outdoor high voltage distribution cabinet, the structure is as shown in fig. 1 to 3, including the cabinet body 6 and ventilation pipe 2. Wherein, the relative both sides of the cabinet body 6 lateral wall respectively is equipped with along the air inlet and the gas vent that the thickness direction runs through. Usually, one side of the cabinet body 6 is provided with a cabinet door, and the air inlet and the air outlet are arranged at the other two sides. Air within the cabinet 6 is exhausted through the exhaust port while air outside the cabinet is admitted through the intake port. The air inlet may be embodied as a rectangle, circle or other regular or irregular shape. The size of the air inlet is usually not more than 50cm². Of course, the shape of the air outlet may be any shape, preferably rectangular or circular, and the size of the air outlet is generally equal to that of the air inlet and does not exceed 1/5 on the side of the cabinet 6. In order to ensure that the air in the cabinet can be smoothly discharged, the exhaust port is connected with a ventilation pipe 2, and a forced ventilation assembly is arranged in the ventilation pipe 2. The forced ventilation subassembly can make the air discharge from ventilation pipe 2, and then makes near the gas outlet produce little negative pressure, and gas constantly flows from the gas outlet under the negative pressure effect. In addition, in order to avoid rainwater to get into ventilation pipe 2, the top of ventilation pipe 2 is equipped with rain-proof cover 1. The prior art can be referred to for other structures of the cabinet body 6, and a protective ceiling can be mounted above the cabinet body 6.

Alternatively, as shown in fig. 3, the air inlet is located at the upper part of the side wall, and in order to ensure the heat dissipation effect, the air inlet is usually arranged at the top of the side wall. The exhaust port is located at the lower part of the side wall where the exhaust port is located. The high temperature in the cabinet body 6 and the temperature difference generated outside the cabinet are main reasons of the outdoor high-voltage power distribution cabinet, and the hot air has low specific gravity and is generally gathered at the top of the cabinet body 6. When the cold air outside the cabinet body 6 enters the cabinet body 6 from the air inlet at the top of the cabinet body 6, the cold air can directly contact with the top of the cabinet body 6, so that the top of the cabinet body 6 is cooled, and further condensation is reduced.

Further, for improving the cooling effect, the top of the side wall of the cabinet body 6 can be provided with a plurality of air inlets along the length direction, so that the contact area between the cold air and the top of the cabinet body 6 is increased. In addition, the air inlet may be further provided obliquely, which gradually increases in height in a direction toward the inside of the cabinet 6. The air outside the cabinet body 6 flows towards the top of the cabinet body 6 after entering the air inlet, so that the direct heat exchange between the cold air and the top of the cabinet body 6 can be ensured, and the aim of reducing the temperature of the top of the cabinet is fulfilled.

Outdoor high voltage distribution cabinet does not set up external power supply usually, therefore, the forced draft subassembly need adopt the ventilation unit who need not the distribution. Optionally, the forced ventilation assembly is an unpowered balloon 3. The unpowered wind ball 3 can draw air out of the ventilation pipe 2 by wind energy. In order to reduce corrosion, the unpowered wind ball 3 can be made of stainless steel.

In addition, the ventilation pipe 2 is arranged along the vertical direction, the upper end of the ventilation pipe 2 is higher than the top surface of the cabinet body 6, and meanwhile, the cross section area of the ventilation pipe 2 is gradually reduced from bottom to top. The unpowered wind ball 3 can be fixed at the top end of the ventilation pipe 2 through welding or integrated forming and the like, and good sealing performance and mechanical strength are guaranteed between the unpowered wind ball and the ventilation pipe. The ventilation pipe 2 can utilize the chimney effect to enable the exhaust port to generate negative pressure, and meanwhile, the ventilation pipe is matched with the unpowered wind ball 3 to ensure that gas in the cabinet stably flows out, so that the aim of cooling is fulfilled.

Optionally, in order to ensure the strength, the ventilation pipe 2 may be made of a metal material, and the inlet of the ventilation pipe 2 is welded and fixed to the periphery of the exhaust port. The ventilation pipe 2 can be attached to the side wall of the cabinet body 6 and fixed in a welding or clamping mode and the like, and the wind resistance of the ventilation pipe 2 is further improved.

Optionally, rain-proof cover 1 links to each other with unpowered wind ball 3's top, and modes such as welding is fixed or threaded connection fix between the two. The top of the rain cover 1 is circular, and the diameter of the rain cover is 2-4 times of the diameter of the unpowered wind ball 3. The lower end of the rain cover 1 is higher than the joint of the unpowered wind ball 3 and the top end of the ventilation pipe 2. The rain cover 1 can be made of plastic or stainless steel and other materials. Certainly, the shape of the rain cover 1 can be set by a user according to needs, and is not limited herein. It should be noted that the joint of the ventilation pipe 2 and the cabinet body 6, the joint of the ventilation pipe 2 and the unpowered wind ball 3, and the joint of the unpowered wind ball 3 and the rain cover 1 all need to be subjected to rain-proof and rust-proof treatment, for example, a coating is set for corrosion prevention, so that the joint damage caused by rain corrosion is avoided.

Optionally, a protective cover 4 is arranged on the outer side of the air inlet, and a waterproof and dustproof filter screen 5 is arranged in the protective cover 4. Air outside the cabinet body 6 can enter the air inlet after passing through the waterproof and dustproof filter screen 5. In order to ensure the waterproof and dustproof effects, the waterproof and dustproof filter screen 5 should have a protection level above IP 55.

Alternatively, as shown in fig. 4, the shield 4 is substantially rectangular parallelepiped. The protection cover 4 is generally made of a metal material, and is fixed to the outer periphery of the air inlet at the rear side thereof by welding or integrally molding, and the protection cover 4 completely covers the air inlet. The lower side of the protective cover 4 is open, and air outside the cabinet 6 can enter the cabinet 6 along the opening. The waterproof and dustproof filter screen 5 is arranged at the opening part of the protective cover 4.

Specifically, the lower part of the protective cover 4 is provided with an insertion groove 41, and one side of the waterproof and dustproof filter screen 5 is provided with a handle 51. The waterproof and dustproof filter screen 5 can be quickly disassembled and assembled through the handle 51. In addition, in order to prevent the protective cover 4 from being corroded, the surface of the protective cover is also coated with protective coatings such as insulating paint.

In this embodiment, outdoor high voltage distribution cabinet has set up air inlet and gas vent, and the gas vent links to each other with ventilation pipe 2, is equipped with the forced draft subassembly in the ventilation pipe 2. High-temperature gas in the cabinet body 6 is discharged through the ventilation pipe 2, and the outdoor high-voltage power distribution cabinet and the external environment can be maintained in a smaller temperature difference range, so that the possibility of condensation in the cabinet body 6 is reduced, and the risk of damage to power equipment is reduced.
