[0009] Preferably, fixing holes are provided on both sides of the front and rear of the mounting plate.

[0010] Preferably, the rollers are all universal wheels.

[0011] Beneficial Effects

[0012] The above one or more technical solutions in a conveniently installed dry-type transformer provided by the embodiment of the utility model have at least one of the following technical effects:

[0013] The utility model adopts the above technical scheme, and the support rod is rotated by rotating four hand wheels at the same time. Under the action of the thread, the roller moves downward and contacts the bearing platform to lift the dry-type transformer upward, so that the two mounting plates on both sides of the bottom of the bridge plate leave the bearing platform. At this time, the position of the mounting plate can be moved by loosening the adjusting nut, so that the installation size of the dry-type transformer can be adjusted according to the specifications of the bearing platform, thereby facilitating the installation of the dry-type transformer on the bearing platform, effectively improving the installation efficiency of the dry-type transformer, and improving the installation flexibility and application scope of the dry-type transformer; and the roller makes it possible to push the dry-type transformer to perform fine adjustment of the angle and position, so that the staff can adjust the dry-type transformer more labor-saving when installing it.
