Ventilated amorphous dry-type transformer soundproof outer box

Abstract

The invention provides a ventilation type noncrystalline dry type transformer sound insulation outer box. The box body is composed of an outer shell and a bottom plate, wherein the outer shell is composed of an outer metal plate, a middle sound insulation mat and an inner fire-resistant waterproof acoustic board, the bottom plate comprises bottom plate steel channels, shock insulation bodies and padding, a longitudinal air inlet hush pipe is arranged in the rear outer shell of the box body, the upper end of the air inlet hush pipe is an air inlet, and the lower end of the air inlet hush pipe is an air outlet. An air exhaust hush pipe is arranged in the outer shell on one side of the box body, the front end of the air exhaust hush pipe is provided with a first air outlet and an exhaust fan, the rear end of the air exhaust hush pipe is provided with a second air outlet, and the second air outlet is formed in the upper portion of one side of the box body. The exhaust fan is connected with a power source through a manual / temperature-control switch. The outer shell with the sound absorption structure is used, the bottom plate with the shock absorption structure is used, the ventilation heat dissipation structure which can be controlled manually and automatically is added in the box body, and therefore the outer box can protect a noncrystalline dry type transformer more scientifically, and influences on the environment are smaller.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to the applicable auxiliary equipment for amorphous dry-type transformers, which is a ventilated sound-proof outer box suitable for relatively large amorphous dry-type transformers. 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 produce some noise when they are working. If the outer box does not have a noise reduction (sound) structure, the noise generated by the amorphous dry-type transformer will penetrate the box and directly impact on the environment.

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 produce some noise when they are working. If the outer box does not have a noise reduction (sound) structure, the noise generated by the amorphous dry-type transformer will penetrate the box and directly impact on the environment
