Abstract

The invention relates to the technical field of transformer application, in particular to a noise reduction device for dry-type transformers in workshops. It includes a housing, a temperature measuring mechanism and an electromagnetic mechanism. The housing is a box structure with a cover, and the housing includes a sound insulation layer; the side wall of the housing is provided with through ventilation holes; the temperature The measuring mechanism includes a temperature measuring bottle, a temperature measuring rod, a windshield and a magnet block, and the windshield can completely cover or completely open the ventilation hole; the electromagnetic mechanism includes a magnet rod, a solenoid, a rectifier and a metal rod. Through the comprehensive function of the temperature measuring mechanism and the electromagnetic mechanism, the present invention automatically adjusts the exposed area of ​​the ventilation hole after measuring the relative strength of the heat dissipation requirement and the noise reduction requirement of the dry-type transformer, which can take into account both the noise reduction requirement and the ventilation requirement of the transformer. cooling needs.

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...
