The sound-insulating housing 1 may be fixed to the target position by any fixing means, for example, a detachable connection or a non-detachable connection.

After the upper end of the transformer body 2 is fixed to the bottom wall 12 of the sound insulation box 1 by the flexible hanging rope 31, the position of the transformer body 2 relative to the sound insulation box 1 is determined under the action of the gravity of the transformer body 2. However, considering the stability of the operation of the transformer body 2, the horizontal position of the transformer body 2 cannot be fixed by using only the flexible suspension ropes 31.

For this purpose, an auxiliary holder 32 is provided at the lower end of the transformer body 2, the auxiliary holder 32 mainly serving to assist in positioning the position of the transformer body 2 relative to the sound insulation case 1, and the auxiliary holder 32 only serves an auxiliary function. Thus, the auxiliary holder 32 is only used to position the horizontal position of the transformer body 2 with respect to the sound insulation box 1. The strength of the connection between the transformer body 2 and the auxiliary holder 32 does not need to be too high.
