The bottom surface of the support 20 is provided with a containing cavity 31, the heat dissipation fan 30 is arranged in the containing cavity 31, and the heat dissipation fan 30 is spliced with the containing cavity 31. The top surface of the support 20 is penetrated with a heat dissipation hole 32, and the heat dissipation hole 32 is communicated with the accommodating cavity 31. A telescopic member 33 is fixed in the middle of the accommodating cavity 31, and specifically, the telescopic member 33 may be a telescopic rod. The telescopic end of the telescopic member 33 is universally hinged with the top surface of the heat dissipation fan 30.
It should be noted that, referring to fig. 1, the peripheral side of the box transformer body 1 is provided with ventilation holes 34.
When the heat dissipation fan 30 is started, the heat dissipation fan 30 sucks the heat below the transverse supporting plate 3 to the upper side of the transverse supporting plate 3, and under the action of the moving holes 8, the heat inside the box transformer body 1 is circulated, so that the circulation of air is enhanced, and finally the air is emitted to the outside of the box transformer body 1 through the ventilation holes 34, so that the service life of the equipment is prolonged.
Referring to fig. 3, in order to facilitate the cable corresponding to the use of the apparatus to be passed through the box transformer body 1, an upper wire inlet hole 35 is formed in the top surface of the box transformer body 1. The bottom surface of the box transformer body 1 is penetrated with a lower wire inlet hole 36. The cable connection of the transformer unit module 5 is facilitated by the upper wire inlet hole 35. The cable connection of the high-voltage cabinet unit module 4 and the low-voltage distribution unit module 6 is facilitated under the action of the lower wire inlet hole 36.
The working principle of the compact box transformer is as follows:
It is first necessary to determine the installation positions of the high-voltage cabinet unit module 4, the transformer unit module 5, and the low-voltage distribution unit module 6 in the box transformer body 1. In this embodiment, the high-voltage cabinet unit module 4 is fixedly mounted on one side of the vertical partition plate 2, the low-voltage power distribution unit module 6 is fixedly mounted on the other side of the vertical partition plate 2, and the low-voltage power distribution unit module 6 is located below the horizontal support plate 3. The transformer unit module 5 is fixedly installed at the other side of the vertical partition plate 2, and the transformer unit module 5 is positioned at the top surface of the horizontal support plate 3.
Then the height position of the transverse supporting plate 3 is determined, the positioning piece 15 can be started first, and the telescopic end of the positioning piece 15 drives the fixing seat 7 to be lifted to the required height position. Then, the locking piece 12 is driven to slide in a direction away from the limiting ring 13, so that the stepped groove 11 is opened. Then, the fixing rods 10 on two sides of the transverse supporting seat are inserted into the stepped groove 11 from bottom to top, meanwhile, the unlocking piece 12 is released, and under the action of the first spring 14, the locking piece 12 locks the fixing rods 10 in the stepped groove 11, so that the transverse supporting plate 3 is fixed at the current height position.
When the interval width of the left side and the right side of the vertical partition plate 2 needs to be adjusted, the position of the vertical partition plate 2 can be adjusted in a horizontal movement mode, the vertical partition plate 2 drives the second sub-plate 18 to move through the fixing seat 7, and the second sub-plate 18 and the first sub-plate 17 relatively move through the supporting piece 20. After the adjustment to the required interval width, the transformer unit module 5 is then mounted on the transverse support plate 3, the pressing piece 26 is pressed under the gravity of the transformer unit module 5, and the pressing piece 26 finally drives the second locking teeth 25 to engage with the first locking teeth 27, so as to complete the mutual fixation among the first sub-board 17, the supporting piece 20 and the second sub-board 18.
And finally, sequentially installing the high-voltage cabinet unit module 4 and the low-voltage distribution unit module 6 in the corresponding sections to finish the three-dimensional installation of the high-voltage cabinet unit module 4, the transformer unit module 5 and the low-voltage distribution unit module 6 in the transformer substation body 1.
In summary, the high-voltage cabinet unit module 4, the transformer unit module 5 and the low-voltage distribution unit module 6 are installed in the box transformer body 1, so that the box transformer product meets the perfect protection and communication functions of the power system requirement. And through the three-dimensional installation of high-voltage cabinet unit module 4, transformer unit module 5 and low-voltage distribution unit module 6, be favorable to furthest compression installation space, improve the space utilization of case change body 1 inner chamber.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
