Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, unless otherwise specified, the terms "upper, lower, left, right, front, rear, inner, and outer" and the like included in the terms refer to the orientation of the terms in the normal use state or the common names understood by those skilled in the art, and should not be construed as limiting the terms.

Referring to fig. 1-2, a power transformer is shown, comprising: the transformer comprises a protection box body 1 and a transformer body 2 arranged in the protection box body 1, wherein the top end and the bottom end of the transformer body 2 are connected with the inner wall of the protection box body 1 through a plurality of dampers 4; the outer top surface of protection box 1 is provided with high-voltage bushing 6, high-voltage bushing 6 through stretching into lead wire 9 in the protection box 1 with the end connection of electricity of transformer body 2 is connected, the side of protection box 1 is provided with shutter 5 and exhaust fan 10.

Through the implementation of the technical scheme, the power transformer can have certain protective capacity in outdoor work, and meanwhile has good ventilation and heat dissipation performance and shock absorption performance. If can play the safeguard effect through protection box 1, in the cooperation through exhaust fan 10 and shutter 5 with the air inflow protection box 1 of external world, the hot-air outgoing in the protection box 1 simultaneously can play absorbing effect through a plurality of attenuators 4 in the in-process of transportation, can prevent that 2 internal elements of transformer body from damaging.

In this embodiment, in order to further improve the damping stability, the plurality of dampers 4 at the top end of the transformer body 2 are distributed along the edge, and the plurality of dampers 4 at the bottom end of the transformer body 2 are arranged in a matrix.

In this embodiment, in order to improve the filtering effect, a filter screen 11 capable of covering the corresponding louver 5 is provided on the inner wall of the shielding case 1. The filter screen 11 can be ordinary filter screen 11 filters dust and particle impurity, of course, the structure of filter screen 11 can also be as: the net bodies arranged at the inner side and the outer side and the sponge interlayers arranged in the middle can be arranged at the periphery of the filter screen 11 for reinforcement by frames.

In this embodiment, in order to facilitate the removal and replacement of the strainer 11, the strainer 11 is detachably mounted to the inner wall of the shielding case 1 by a plurality of bolts 12.
