Abstract

The invention discloses a transformer door-shaped support sound insulation cotton device. A door-shaped support is composed of a left side base, a right side base and a supporting plate connected between the top of the left side base and the top of the right side base, the door-shaped support comprises frame plates installed in a front side cavity opening and a rear side cavity opening of a channel below the supporting plate, and a sound insulation cotton layer is fixed to the outer plate face of each frame plate. A plurality of rotating shafts are rotatably mounted on the left frame edge of the front frame plate, the rear end of each rotating shaft extends to the rear frame plate, a sound absorption membrane is fixed to each rotating shaft, and a plurality of heat conduction pieces are fixed to the inner plate face of the right frame edge of the rear frame plate and supported at the bottom of the right side of the sound absorption membrane in a one-to-one correspondence mode. The noise interference generated by the transformer can be effectively reduced when the method is used for testing the transformer.

Description

technical field [0001] The invention relates to the field of transformer testing devices, in particular to a sound-insulating cotton device for a transformer door-shaped bracket. Background technique [0002] The finished transformer needs to be placed on the door-shaped support for test and test. The door-shaped support is generally composed of left and right side seats and a top plate fixed on the top of the left and right side seats. The transformer is placed on the top plate for test and test work. Noise will be generated during the test operation of the transformer, and the channel under the top plate will form a resonance cavity to amplify the noise. This amplified noise will interfere with the sound level test of the transformer. Contents of the invention [0003] The object of the present invention is to provide a sound-insulating cotton device for a transformer door-shaped bracket to solve the problem of amplifying noise when the door-shaped bracket is used for t...
