Improved safety power transformer with insulating oil checking and replacement

摘要

The present invention relates to an improved safety power transformer with insulating oil checking and replacement function, more specifically to an improved safety power transformer with insulating oil checking and replacement function which has a mechanical cooling structure that effectively can cool heat generated due to the characteristics of a power transformer, and at the same time can reduce environmental damage caused by noise, can enhance its own vibration absorption suppression function to safely protect against an external force such as an earthquake, can safely protect the transformer by the respiration function of outer air during the contraction and expansion of the insulating oil, and can check visually the deterioration of the oil due to use for a long time and can be immediately replaced if necessary to further enhance safety. The power transformer includes coolers at both sides of a transformer case.
