technical field

The utility model relates to the technical field of electrical equipment, in particular to a heat dissipation structure for a box-type substation shell.

Background technique

The box-type substation is favored by people because of its compact structure, small footprint, and relatively low construction cost. At present, the box-type substations in production and use are basically composed of box-type substations, transformers, power distribution cabinets and other electrical equipment, and all electrical equipment are installed on the box-type base.

In the existing box-type substation products, since all the electrical equipment is installed in the box shell, many electrical equipment itself will generate a lot of heat, and the box-type substation requires that it is not exposed to the sun and rain. Water will enter, so the contradiction between heat dissipation and sealing of box-type substation is difficult to adjust. The existing heat dissipation structure of the box-type substation shell generally adopts the installation of an exhaust fan under the heat insulating gas building. The heat generated by the electrical equipment enters the heat insulating gas building through the exhaust fan, and passes through the two ends of the heat insulating gas building. Exhaust hot air downwards. The above-mentioned heat dissipation structure is inconvenient to install, the heat entering the heat insulation air building cannot be fully dissipated outward, the heat is accumulated on the top of the substation and cannot be discharged, and the heat dissipation efficiency is low.

Detailed ways

Referring to Fig. 1, the utility model will be described in detail below in conjunction with the accompanying drawings.

The heat dissipation structure of the shell of a box-type substation described in the utility model includes a heat-insulating gas building 1, the interior of the heat-insulating gas building 1 is hollow to form a channel 2, and the lower part of the heat-insulating gas building 1 is provided with an air intake Ventilation holes 3 are opened at both ends of the heat-insulating air building 1, and an exhaust fan 4 is arranged in the heat-insulating air building 1. In the utility model, the heat dissipation structure of the casing of the box-type substation includes a heat-insulating gas building 1, and the interior of the heat-insulating gas building 1 is hollow, thereby forming a channel 2 for heat flow, as shown in Figure 1, The arrow in the figure is the direction of heat flow. Since the air intake hole (not shown in the figure) is provided under the heat insulating air building 1, it is convenient for a large amount of heat flow generated by various electrical equipment in the shell of the box-type substation to enter the channel 2 of the heat insulating air building 1 during the working process. Inside, thereby through the ventilation hole 3 that insulation air building 1 two ends offer outward heat dissipation. In order to speed up the heat dissipation, the utility model is equipped with an exhaust fan 4 in the channel 2 of the heat insulating air building 1, which can speed up the flow of heat flow and quickly discharge the heat flow accumulated on the top of the substation to the outside. The structure is simple, easy to install, and heat dissipation efficient.

As a preferred embodiment, an exhaust fan 4 is provided at both ends of the heat insulating air tower 1 . Since both ends of the heat-insulating air building 1 are provided with ventilation holes 3, in order to quickly and evenly discharge the heat flow outward, the utility model is provided with an exhaust fan 4 at both ends of the heat-insulating air building 1 to enter the heat-insulating air building. When the heat flow of the passage 2 of the gas building 1 is discharged to both ends, the speed of progress of the heat flow can be accelerated by the exhaust fan 4 arranged near the vent hole 3, which enhances the practicability of the present utility model.

Further, a ventilation louver 5 is provided between the exhaust fan 4 and the ventilation hole 3 at the corresponding end. In the present utility model, a ventilation louver 5 is provided at the connection between the passing ventilation hole 3 and the outside world. The rapid discharge of the heat flow in the heat-insulating air building 1 prolongs the service life of the exhaust fan 4 and enhances the practicability of the utility model.

Still further, a heat insulation board 6 is arranged above the heat insulation air tower 1 . Since the box-type substation is usually placed outdoors, in this utility model, by setting the heat insulation board 6 above the heat-insulating gas building 1, it can effectively prevent rainwater from entering the heat-insulating gas building 1, and prevent long-term high-temperature sun exposure from causing damage. Increase the temperature of the insulated gas building 1. At the same time, the utility model also sets a ventilation net 7 under the heat-insulating gas building 1, which can diffuse the heat of the heat-insulating gas building 1 to the outside world, avoiding a substantial increase in the temperature in the shell of the box-type substation, and effectively improving the efficiency of the utility model. practicality.
