Description

TECHNICAL FIELD

[0001] The utility model relates to box type substation heat dissipation technical field, concretely relates to a new energy box transformer low voltage room heat dissipation structure. BACKGROUND

[0002] With the development of new energy technology, box type substations are widely used in solar power stations, wind power plants and other occasions. These box type substations usually integrate transformers, high and low voltage power distribution equipment and auxiliary equipment, and are isolated by partitions, realizing efficient conversion and distribution of electric power.

[0003] However, in the actual operation process, a large amount of heat will be generated in the transformer during power conversion, and if it is not effectively managed, the heat may be conducted along the copper bar, causing the temperature of the entire copper bar in the low voltage chamber to be too high, thereby affecting the stability and life of the equipment in the low voltage chamber.

[0004] Therefore, there is an urgent need for a new energy box transformer low voltage room heat dissipation structure that can dissipate heat from the copper bar in the low voltage chamber and avoid the problem of overheating of the entire copper bar caused by heat generated by the transformer.

[0008] Further, a ventilation box is arranged on the outer wall of the low voltage chamber box, a plurality of first through holes are formed on the lower end face of the ventilation box, a second through hole is formed on the side wall of the ventilation box, the second through hole is in communication with the air inlet of the hair drier, and the diameter of the second through hole is greater than that of the air inlet of the hair drier.

[0009] Beneficial effects: In this scheme, the air inlet of the ventilation box is the first through hole, which is arranged on the lower end face, that is, the air inlet of the ventilation box is arranged downward, which can reduce the possibility of direct rainwater entering, especially in outdoor environment, such design helps waterproof, protects internal electrical equipment from water damage. At the same time, when the air inlet is located below, it is easier to clean and check, and it is convenient for maintenance personnel to carry out routine maintenance work.

[0010] The diameter of the second through hole is greater than that of the air inlet of the hair dryer, which means that more air can pass through, increasing the ventilation volume and helping to improve the heat dissipation effect.

[0011] Further, it further comprises a filter screen arranged on the ventilation box close to the first through hole.

[0012] Beneficial effects: The setting of the filter screen can block dust, fibers and other impurities in the air from entering the internal equipment, reducing the performance decline and shortening the service life of internal components caused by dust accumulation. The filter screen can prevent insects or other foreign matter from entering the internal equipment to avoid causing short circuit or other electrical faults.

[0014] Beneficial effects: By setting the first and second mounting holes at the same height, the filter screen can be easily inserted or extracted, simplifying the installation and replacement process of the filter screen. The operator can complete the maintenance work without complex tools, improving work efficiency. Installing the filter screen on the same horizontal line can ensure the consistency of the filter screen in the entire width, avoiding the situation that air flows around or is not uniformly filtered due to different installation positions, thereby improving the filtering effect.

[0015] By setting symmetrical mounting holes on the left and right sides, the filter screen can be better supported, avoiding deformation or falling off caused by uneven force on one side, and enhancing the structural stability of the filter screen installation.

[0016] The filter screen is arranged above the first through hole, so that the lower end face of the ventilation box provided with multiple first through holes provides protection for the filter screen, greatly improving the safety of the filter screen.

[0017] Further, the left and right sides of the lower end face of the ventilation box are provided with protrusions, and the protrusions are provided with first and second insertion holes for inserting the filter screen.

[0018] Beneficial effects: in this scheme, the installation of the filter screen is realized through the setting of the first insertion port and the second insertion port on the protrusion, so that the air entering the ventilation box first passes through the filter and then enters, greatly improving the purity of the air in the ventilation box, and avoiding the problem that the residual dust in the ventilation box cannot be cleaned.

[0019] At the same time, the lower end surface of the ventilation box can also provide support for the filter screen, greatly improving the service life of the filter screen.

[0020] Further, the outer side of the filter screen is also provided with a protective screen.

[0021] Beneficial effects: the setting of the protective screen can provide additional barriers, further block larger particulate matter, insects and other sundries from entering the ventilation system, thereby reducing the burden of the filter screen and prolonging the service life of the filter screen. Prevent accidental collision or impact directly on the filter screen, reduce the risk of failure of the filter screen due to physical damage.

[0022] Further, the included angle between the inner wall of the upper end surface of the ventilation box and the outer wall of the low-voltage chamber box is an acute angle.

[0023] Beneficial effects: in this scheme, the acute angle design can make the airflow path more smooth, reduce the resistance of airflow at the turning place, thereby improving the ventilation efficiency and reducing the noise. The setting of the acute angle can avoid the problem of water accumulation on the upper end surface of the ventilation box. BRIEF DESCRIPTION OF DRAWINGS
