Sound-insulation case for small amorphous dry-type transformer

Abstract

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 structure is arranged below the case body, so that protection for the small amorphous dry-type transformer is more scientific, and influences on environment are less.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to the applicable auxiliary equipment of the amorphous dry-type transformer, which is a small sound-proof outer box of the amorphous dry-type transformer. Background technique [0002] When the amorphous dry-type transformer is installed outdoors, it is generally necessary to configure an outer box for protection outside. The box body of the existing outer box is generally made of thin iron plate or aluminum plate, which can protect the amorphous dry-type transformer from impact. However, the existing outer box has almost no noise reduction or noise suppression structure. Amorphous dry-type transformers will generate some noise during operation. If the outer box has no sound insulation structure, the noise generated by amorphous dry-type transformers will penetrate the box and directly affect the environment. . Contents of the invention [0003] The purpose of the present inven...

Problems solved by technology

The box body of the existing outer box is generally made of thin iron plate or aluminum plate, which can protect the amorphous dry-type transformer from impact. However, the existing outer box has almost no noise reduction or noise suppression structure.

Amorphous dry-type transformers will generate some noise during operation. If the outer box has no sound insulation structure, the noise generated by amorphous dry-type transformers will penetrate the box and directly affect the environment.
