At this time, since the protective cover 600 is no longer above the mesh cover 500, the second top mesh plate 560 and the second side abutting plate 551 are pushed by one end of the first L-shaped push plate 611 and one end of the second L-shaped push plate 612. The two side mesh panels 550 rotate, eventually making the second mesh cover 520 in an open state; at the same time, the long push plate 621 and the long transmission plate 622 also rotate the first top mesh panel 540 and the first side mesh panel 530 in the same way, eventually making the first mesh cover 510 in an open state, so that all the sleeves are exposed to the outside world, achieving the best heat dissipation state in a high temperature and windless environment, while reducing the risk of damage to the sleeve connection, and facilitating maintenance operations of the maintenance personnel on the sleeve connection.

[0055] It is worth noting that when the mesh cover 500 and the protective cover 600 need to be reset, the electric telescopic rod 710 can be controlled to operate in reverse, and the corresponding mesh plate can be reset through the first top torsion spring 515, the first side torsion spring 517, the second top torsion spring 525, and the second side torsion spring 527.

[0056] Furthermore, the high-voltage bushing 410 is provided with a high-voltage terminal 411, and a high-voltage terminal 412 is installed on the high-voltage terminal 411; the low-voltage bushing 420 is provided with a low-voltage terminal 421, and a low-voltage terminal 422 is installed on the low-voltage terminal 421. The high-voltage terminal 412 and the low-voltage terminal 422 are connected to the corresponding cables respectively. It is worth noting that the internal structure of the transformer body 100 of the present application is composed of an iron core and a coil, which is a prior art and will not be described in detail here.

[0057] Furthermore, heat sinks 200 are fixedly provided on four sides of the transformer body 100, four lifting rings 120 are fixedly connected around the top of the transformer body 100, and an oil valve 130 is also provided on the top of the transformer body 100; a mounting frame 300 is provided at the bottom of the transformer body 100, and the mounting frame 300 includes four L-shaped mounting steel grooves 310 fixedly connected around the bottom of the transformer body 100, both ends of the L-shaped mounting steel grooves 310 extend out of the outside of the transformer body 100, and both ends of the L-shaped mounting steel grooves 310 are provided with mounting holes 320. The heat sink 200 dissipates heat for the transformer body 100, the lifting ring 120 facilitates the lifting of the transformer body 100, and the oil valve 130 is used to add insulating oil; at the same time, the L-shaped mounting steel groove 310 of the present application can not only be installed on the outdoor mounting frame in different directions to cope with special installation environments, but also the structural design of the L-shaped mounting steel groove 310 can effectively protect the corners of the transformer body 100, and prevent the corners of the transformer body 100 from being damaged by collision and causing leakage of insulating oil.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
