Description

Prefabricated box-type substation heat dissipation and ventilation device

Technical Field

The utility model relates to an electric power system transformer substation technical field especially relates to a prefabricated formula box-type substation heat dissipation and ventilation device.

Background

The box-type substation replaces the original civil power distribution room and power distribution station, becomes a complete set of power transformation and distribution device which is more widely used, and users can customize the box-type substation according to different use conditions and load grades, so that the use and the release are more convenient. In recent years, the development of box-type substations is faster and faster, the investment is small, the effect is quick, the box-type substations can save various expenses such as the capital construction cost required for building conventional transformer substation distribution rooms, and a large amount of capital construction investment can be saved; the box-type transformer substation also has the advantages of simple installation and rapid power supply, and can be installed and completely powered for several hours under the condition of well-made installation foundation, so that the power utilization of resident life and industrial production is ensured in time. Compared with a conventional transformer substation, the box-type transformer substation needs lower cost and is quicker to put into use, and more convenience is provided for users in various industries.

At present, box-type substations in China are mostly used in field places, some substations are exported to southeast Asia rainy countries such as Malaysia and the like, so the outer shell of the substation is often contacted with rainwater, high-power equipment such as transformers and the like are arranged inside the substation, and a large amount of heat can be dissipated inside the substation, so ventilation and heat dissipation measures must be taken, in the prior art, a heat dissipation device is usually arranged on a substation shell and generally comprises heat dissipation holes and pressure plates outside the heat dissipation holes, the pressure plates are welded outside the heat dissipation holes through spot welding, gaps exist between the pressure plates and the heat dissipation holes, hot air inside the substation is dissipated into the air through the gaps, however, due to long-term rainwater contact, rainwater inevitably enters the substation through the gaps between the pressure plates and the heat dissipation holes, if too much rainwater enters in a short circuit, electrical components, therefore, the problem of rain invasion prevention of the heat dissipation vent holes of the transformer substation becomes a problem in the field.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above shortcoming of prior art, the utility model provides a prefabricated formula box-type substation heat dissipation ventilation unit, its simple structure, reasonable in design can solve the rainwater well and get into the inside problem of transformer substation through heat dissipation ventilation hole.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a prefabricated box-type substation heat dissipation and ventilation device comprises a substation shell, heat dissipation holes and a buckle plate, wherein the substation shell is provided with a plurality of heat dissipation holes, the top of the buckle plate is provided with an end plate, the end plate is fully welded with the substation shell to ensure that rainwater cannot enter the buckle plate from the top of the buckle plate, and two sides of the buckle plate are fixed on the substation shell on two sides of the heat dissipation holes in a spot welding manner; still be equipped with the baffle between louvre and buckle on the transformer substation's casing, the baffle is 2 the both sides of dividing in the louvre, and its baffle thickness is less than the buckle plate thickness, the buckle can be with including baffle, louvre parcel.

Furthermore, the clearance between the two sides of the pinch plate and the transformer substation shell is 2-3 mm.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a prefabricated formula box-type substation heat dissipation and ventilation device, through the transformer substation shell, the louvre, the design of buckle and baffle, hot-air in the transformer substation shell passes through the louvre, in the clearance between buckle and the transformer substation shell is discharged into the air, realize the heat exchange, when raining, get into the rainwater in the clearance between buckle and the transformer substation shell, blocked by the baffle, and under the effect of gravity, along the baffle downflow, guarantee that the rainwater can not get into the louvre, just guarantee that the rainwater can not get into inside the transformer substation shell through the louvre, cause unpredictable's loss.
