NOISE REDUCTION DEVICE FOR REGENERATION OF ELECTRICAL POWER

摘要

PURPOSE: A noise reduction device for electrical power regeneration is provided to supply power to measuring sensors for a transformer by installing an electricity storage unit in a double container. CONSTITUTION: A steel plate is formed in the outer side of a transformer to prevent noise. A sound-absorbing material(303) is installed at the inner side of the steel plate. The sound-absorbing material absorbs the noise generated in the transformer. Multiple thermoelectric elements(304) are fixed between the outer side and the sound-absorbing material. An electricity storage unit(401) connects multiple thermoelectric elements and stores electric power.
