Abstract

The base air-inlet type substation waterproof and heat-dissipating box, which is installed on the upper opening of the base, is composed of a bottom plate, a wall plate, a front door, an inner roof and an outer inclined roof. The fan is installed with a spacer on the air inlet window, an air inlet is installed on the side of the base, a grille is installed on the air inlet, an inlet fan is installed on the bottom plate of the box, and the edge of the top plate below the box top protrudes On the outside of the wallboard, there is a downward air outlet on the edge of the top board protruding from the outside of the wallboard. A spacer is installed on the air inlet window, the front end is inclined upwards, and the rear end is bent downwards to form an oblique hook shape. Because the outer slanted roof of the box retains the overall structure, the waterproof function is greatly enhanced; because the fan blows directly on the slanted roof, the cooling effect on the slanted roof is good; because the inlet fan installed at the bottom blows directly to the substation equipment, the heat dissipation effect of the equipment is increased; Since the spacer installed on the air inlet window is in the shape of a slanted hook, it can effectively prevent water from splashing on the equipment.

Description

Waterproof cooling box of base air inlet type substation

technical field

The utility model belongs to the technical field of power transmission and transformation equipment, and relates to a base air intake type substation waterproof and heat dissipation box. the

Background technique

In high-voltage transmission lines, many substations that supply power to users are installed outdoors. The substations are equipped with waterproof and sun-proof boxes. Since the substations generate a lot of heat when they are working, the heat needs to be discharged from the box immediately. Therefore, there are installed on the box. Ventilation and heat dissipation system. The box body is generally composed of a bottom plate, wall panels, front door, inner roof and outer slanted roof. The heat dissipation system is composed of air inlet windows installed on the wall panels and front door and fans on the inner roof. It is designed on the outer slanted roof. There is a boss, and the side of the boss is installed with a top outlet window, and an upwardly inclined spacer is installed on the side inlet window. In order to ensure that the installation site will not be flooded, many cabinets are designed to be installed on a base that is above the ground. Due to the complex structure of the top outlet window, the manufacturing cost of this kind of box is relatively high; because the spacer on the side air inlet window is inclined upward, the water splashed from the ground is easy to splash into the box along the oblique seam of the spacer and become distorted. On the fuselage of the electrical equipment, since the airflow can only enter from the side of the box, the cooling effect in the box is not good. the

Contents of the invention

In order to solve the problems in the prior art that the structure of the outlet windshield of the substation box body is complex, the water splashed from the ground is easy to splash on the substation equipment in the box body, and the heat dissipation effect of the box body is not good by using side air intake, the utility model provides A base air-intake type substation waterproof and heat-dissipating box, which is installed on the upper opening of the base, and consists of a bottom plate, a wall plate, a front door, an inner roof, and an outer inclined roof. A fan is installed, a spacer is installed on the air inlet window, an air inlet is installed on the side of the base, a grille is installed on the air inlet, an inlet fan is installed on the bottom plate of the box, and an air inlet is installed on the edge of the roof below the box top. It protrudes outside the wallboard, and on the edge of the top board protruding out of the wallboard, there is a downward air outlet. the

A spacer is installed on the air inlet window, the front end is inclined upwards, and the rear end is bent downwards to form an oblique hook shape. the

With the above technical solution, the air outlet is designed on the outer convex edge of the roof, and the outer slanted roof of the box retains the overall structure, which greatly enhances the waterproof function; the wind blown upward by the fan flows along the slanted roof to both sides after hitting the slanted roof , and finally discharged from the exhaust port, not only can the heat emitted by the substation equipment in the box be dissipated, but also can reduce the temperature on the inclined roof, so that the heat dissipation effect of the whole box can be improved; The air inlet is installed at the bottom of the cabinet, and the intake fan can directly blow the cooling gas entering the base to the substation equipment, increasing the heat dissipation effect of the equipment. the

Since the spacer installed on the air inlet window is in the shape of a slanted hook, when the water splashed from the ground splashes into the oblique seam of the spacer, the bending of the rear end of the spacer can block the water splash, effectively preventing the water from splashing on the equipment. The waterproof effect is enhanced. the
