Abstract

The invention relates to the technical field of transformer application, in particular to noise reduction equipment for a dry-type transformer of a workshop. The equipment comprises a shell, a temperature measurement mechanism and an electromagnetic mechanism, and the shell is of a box structure with a cover and comprises a sound insulation layer; an air exchange hole which is through is formed inthe side wall of the shell; the temperature measurement mechanism comprises a temperature measurement bottle, a temperature measurement rod, a wind baffle and a magnet block, and the wind baffle cancompletely cover or completely open the air exchange hole; the electromagnetic mechanism comprises a magnet rod, a solenoid, a rectifier and a metal rod. According to the noise reduction equipment, through a comprehensive effect of the temperature measurement mechanism and the electromagnetic mechanism, after the heat dissipation demand of the dry-type transformer and the relative intensity of thenoise reduction demand are compared, the exposure area of the air exchange hole is automatically adjusted, and the noise reduction demand and air exchange and cooling demand of the transformer can bemet.

Description

technical field [0001] The invention relates to the technical field of transformer application, in particular to a noise reduction device for dry-type transformers in workshops. Background technique [0002] Compared with oil-immersed transformers, dry-type transformers are more and more used in densely populated areas such as commercial areas and industrial areas due to their small size, easy installation, no need for transformer oil, better fire resistance, and no pollution. place. [0003] However, when the dry-type transformer is running, there is usually a lot of low-frequency noise and a lot of heat. Low-frequency noise is very harmful to the human body, and if the heat dissipation is not timely, the equipment will age rapidly, the service life will be shortened, and the maintenance cost of the equipment will be increased. [0004] In order to solve the above problems, there have been many noise reduction and heat dissipation equipment for dry-type transformers in re...
