Technical Field

The invention relates to the field of box-type substations, in particular to a box-type substation box body heat dissipation device.

Background

The box-type substation is also called a pre-installed substation or a pre-installed substation. The high-voltage switch equipment, the distribution transformer and the low-voltage distribution device are integrated into a whole according to a certain wiring scheme, namely, the transformer voltage reduction and low-voltage distribution functions are organically combined together and installed in a moistureproof, antirust, dustproof, rat-proof, fireproof, antitheft, heat-insulating, fully-closed and movable steel structure box, so that the transformer is particularly suitable for urban network construction and transformation and is a novel transformer substation which is built up after civil engineering transformer substations.

The high-voltage chamber and the low-voltage chamber in the box-type substation generate a large amount of heat during high-voltage and low-voltage conversion, and if the heat is not dissipated in time, the risk is certain. In view of the danger, the box-type transformer substation is mostly arranged outdoors, and the base is generally made of channel steel, angle steel and other materials; the shell and the top cover are made of materials such as channel steel, angle steel, steel plates, aluminum alloy plates, color steel plates, cement plates and the like, and are formed by bending, welding resistance or combination of the materials by using screws, hinges and the like. The top is also filled with heat insulating material with low heat conductivity coefficient, such as rock wool board, polystyrene foam plastic, etc. The materials and the method of the box-type substation can meet technical standards of sun protection, rain protection, rust protection, heat insulation, small animal entering prevention and the like, but the heat insulation filler adopted by the box-type substation can prevent strong solar radiation in hot summer, but also prevents a large amount of heat generated when equipment such as a transformer, a high-low voltage cabinet and the like in the box-type substation runs. In addition, the heat dissipation design of the box body of the box-type substation is not scientific, and usually, only a plurality of vent holes are symbolically formed in the box body, and a scientific air duct is not formed. Therefore, a large amount of waste heat generated by the substation during operation is not discharged in time, and an electrical fault is caused.

By implementing the above technical solution, negative pressure is maintained in the box-type substation box 3 by the upper fan 2, air with low outside temperature is drawn in from the position of the lower louver 1, and hot air in the box-type substation box 3 rises and is drawn out through the upper fan 2 and is discharged through the ventilation holes in the side surface of the box. As shown in fig. 2, during this process, a stable air flow path is formed inside the box-type substation box 3, so that cold air continuously enters the box-type substation box 3, the cold air is heated by heat generated by the transformer operation, and the heated hot air flows upward and is extracted by the upper fan 2. In the process, the heat in the box-type substation box body 3 is continuously exhausted along with the hot air, so that the aim of cooling the box-type substation is fulfilled.

The box-type substation is a compact type of power distribution equipment, so that the upper fan 2 can be installed only on the side surface of the box-type substation box 3, and the second ventilating hole corresponding to the upper fan 2 must be provided on the upper portion of the side surface of the box-type substation box 3. Preferably, the two side surfaces of the box-type substation can be provided with ventilating holes, and the two upper fans 2 are correspondingly arranged, so that a good heat dissipation effect can be achieved. However, some box-type substations are limited by the installation position, and one side of the box-type substation may be adjacent to other equipment, so that the upper fan 2 arranged on one side can achieve better heat dissipation effect.

In this embodiment, preferably, the box-type substation box body heat dissipation device further comprises a dust receiving plate 5, and the dust receiving plate 5 is fixed on the door at a position below the first ventilating hole.
