In order to cope with special environments, people need an outdoor box-type substation.

[0003] Today's outdoor box-type substations usually fix the substation box on an outdoor base, and a rainproof cover is provided on the top of the box to prevent rain. Because the substation is located outdoors, the box is sealed as a whole. In order to balance the temperature and humidity inside and outside the box, vents and cooling fans are provided on the outside of the box.

[0004] This type of outdoor box-type substation has good sealing properties. Although it can withstand general outdoor weather, the outside of the box is equipped with vents and cooling fans. When facing sandstorms and other windy weather, the two are in direct contact with the outdoors, and some fine sand will float into the transformer box. The dust will float into the box, causing dust to accumulate on the equipment in the station, affecting the heat dissipation effect of the equipment. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the openings of the vents and the heat dissipation fans cannot prevent fine sand and dust from entering the transformer box, thereby causing the heat dissipation effect of the box to decrease.

[0007] As an improvement, the sand-proof device includes a sand-proof cloth bag and a T-shaped fixed column located in a box body, the T-shaped fixed column passes through the inside of the sand-proof cloth bag, the bag opening of the sand-proof cloth bag is sealed and connected to the thin column end of the T-shaped fixed column by an elastic sealing belt, the elastic sealing belt is connected to the bag opening of the sand-proof cloth bag by sealant, and the T-shaped fixed column is connected to the box body by electric welding.

[0008] As an improvement, the inner wall of the box is provided with a sand-proof board slide groove for storing a removable sand-proof board. The removable sand-proof board is sealedly connected to the sand-proof board slide groove by a sealing ring, and the open side of the sand-proof board slide groove is on the same side as the box door.

[0009] As an improvement, the material of the detachable sand-proof plate and the sand-proof cloth bag is similar in property to the dust bag material of the bag filter.

[0010] As an improvement, the heat dissipation fan is located on the opposite side of the cabinet door, a heat dissipation fan fixing groove for fixing the heat dissipation fan is provided inside the cabinet, and the T-shaped fixing column is located outside the heat dissipation fan fixing groove.

[0011] As an improvement, an arc-shaped protective plate is provided on the outer side of the vent.

[0012] As an improvement, a sealing step for sealing the box door is provided on the open side of the box body.

[0013] The advantages of the utility model compared with the prior art are: the detachable sand-proof plate is used to block the sand and dust at the ventilating opening, and the sand-proof cloth bag of the sand-proof device is used to block the sand and dust on the outer side of the cooling fan, and the material properties of the detachable sand-proof plate and the sand-proof cloth bag are similar to the dust bag material properties of the bag dust collector, so the detachable sand-proof plate and the sand-proof cloth bag will not affect the heat dissipation of the box while preventing sand.
