Sound-insulation case for small amorphous dry-type transformer

The invention provides a sound-insulation case for a small amorphous dry-type transformer. The sound-insulation case comprises a case body, a housing and a base plate. The housing is composed of an outer metal plate, a middle sound-insulation blanket and an inner fire-resistance water-proof and sound-insulation plate, so that the inner layer of the housing has a sound absorption function. The base plate comprises a base plate steel channel, a shock insulator and padding, and the shock insulator and the padding are capable of reducing shocks produced by the amorphous dry-type transformer during operation. The case body adopts a covering-type structure, a cover composed of the housing can directly sleeve on the base plate and be fixed through bolts. A ventilating louver structure is arranged below the housing at front and rear of the case body. The housing provided with the sound-absorption structure is adopted, the base plate provided with the shock-absorption structure is further adopted, and the ventilating
