Description

Technical Field

[0002] A power transformer is an electrical device used to transform AC voltage and current to transmit AC power. It is generally divided into oil-immersed power transformers and dry-type power transformers. When the transformer is in use, it needs to be fixed on a pole, so a mounting frame is needed to support and install it.

[0003] As disclosed in the authorization announcement number CN208781644U, a mounting frame for a power transformer is disclosed, including a fixed beam and a movable beam, a plurality of limit grooves are spaced apart on the front and rear sides of the upper part of the fixed beam, a continuous slide groove is opened at the center of the inner bottom, a movable beam is slidably installed above the fixed beam, a plurality of clamping blocks are symmetrically arranged at the front and rear of the movable beam, the clamping blocks slide in the limit groove, a plurality of transmission blocks are vertically arranged at the bottom of the movable beam, a screw hole is twisted at the center of the transmission block, a screw rod is passed through the screw hole, the left end of the screw rod is rotatably connected to the fixed beam, and the right end extends out of the fixed beam, a pulley is clamped at the center of the bottom of the transmission block, and the pulley slides in the slide groove.
