GROUND TRANSFORMER HAVING EARTHQUAKE-PROOF FUNCTION CAPABLE OF PROPAGATING DANGEROUS SITUATIONS BY STAGE BY SENSING MOVEMENT OF TRANSFORMER IN CASE OF EARTHQUAKE

摘要

The present invention relates to a ground transformer having an earthquake-proof function capable of propagating dangerous situations by stage by sensing the movement of a transformer in case of an earthquake. According to the present invention, in order to prevent damage to a transformer in case of an earthquake, a plurality of sub damping means are used to damp vertical vibrations delivered to the transformer, a first distance measurement sensor attached to the bottom of the transformer is used to measure a distance between the bottom of the transformer and an upper foundation placed thereunder in case of vertical vibrations, and a second distance measurement sensor attached to the upper side of the transformer is used to measure a distance between the upper side of the transformer and an external case placed thereon. Therefore, information about whether the transformer belongs to a danger stage, in which the transformer can be broken or malfunctioning due to an earthquake, or a stage lower than the danger stage, in which the probability of the transformer to be broken or malfunctioning is high in spite of an earthquake, can be transmitted to an external management server and a manager terminal in accordance with the level of each measurement value.;COPYRIGHT KIPO 2020
