The box-type transformer substation is suitable for mines, factory enterprises, oil-gas fields and wind power stations, replaces the original civil power distribution room and power distribution station, and becomes a novel complete set of power transformation and distribution device. Because the transformer can send a large amount of heats at the course of the work, if not distribute away in time, can influence the load capacity of transformer, consequently, the heat dissipation window has mostly been seted up respectively on the cabinet door of case transformer, and in order to reach waterproof and dirt-proof requirement, these heat dissipation windows must be made into the shutter structure, and in addition, these heat dissipation windows act as air inlet and gas outlet simultaneously, influence the radiating efficiency of box, consequently, how to design the heat dissipation passageway of box becomes the problem that must solve.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a thereby set up the air inlet and the gas outlet of heat dissipation channel respectively at the upper and lower both ends of box and improve the bottom air inlet box-type substation of radiating efficiency for solving above-mentioned technical problem not enough.

In order to realize the above-mentioned purpose, the utility model discloses a bottom air inlet box formula transformer substation, including the box that is used for installing substation equipment, the bottom of box installs the transformer between two parties, transformer week side the air inlet window has been seted up to the bottom, the box is installed on 100 + 500 mm's of higher ground first base station, first base station plane width adaptation bears fixedly the transformer, first base station week side with the air inlet window communicates with each other and forms inlet air channel.

Compared with the prior art, the bottom air inlet box type transformer substation has the advantages that the air inlet window for air inlet is arranged on the periphery of the transformer at the bottom of the box body, so that the air inlet window does not need to be designed for rain drift prevention, and the box door of the bottom air inlet box type transformer substation does not need to be opened when the air inlet window is cleaned, so that safety accidents are avoided; because the transformer is a main heating element of the box-type substation, the density of low-temperature airflow entering the air inlet window on the peripheral side of the bottom of the transformer is reduced after the low-temperature airflow is heated by the transformer, the low-temperature airflow has upward flowing power, and fresh low-temperature air can be continuously sucked from the air inlet window to achieve the optimal natural ventilation and heat dissipation effect; and the transformer is independently installed and fixed on the first base station, and the vibration generated when the transformer runs is directly transmitted to the underground, so that the resonance with the box body and other power distribution equipment is avoided, and the noise of the box transformer substation is effectively reduced.

Preferably, the air inlet window is provided with an air inlet gauze.

Preferably, the second base is arranged below the top corner of the bottom of the box body, and the top surface of the second base is abutted against the bottom of the box body to bear and fix the box body.

Preferably, the middle part of the second base station is provided with a cable channel which is communicated up and down.

Preferably, a power distribution cabinet is arranged above the transformer, and an air duct which is communicated up and down is formed in the middle of the power distribution cabinet.

Preferably, an opening is formed in the top eave of the box body towards the lower side, and the opening is communicated with the air inlet window through the air duct and the space around the transformer.

Preferably, the top of the box body is provided with an air outlet gauze.

Preferably, a heat dissipation fan for performing air cooling heat dissipation on the transformer is further installed in the box body.

Detailed Description

In order to explain technical contents, structural features, implementation principles, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1 and 2, the utility model discloses a bottom air inlet box formula transformer substation, it is including the box 3 that is used for installing substation equipment, and box 3's bottom is installation transformer 5 placed in the middle, air inlet window 7 has been seted up to the bottom of transformer 5 week side, and box 3 is installed on the first base station 1 of higher than ground h (100) and 500mm, and h is preferred 300mm in this embodiment, and fixed transformer 5 is born in the 1 plane width adaptation of first base station, and 1 week side of first base station communicates with each other with air inlet window 7 and forms inlet air channel.
