- Abstract
the transformer is one of the most important equipment in power system, the maximum short current rated current is 25~30 times or more when an outlet short circuit occurs,short current will produce great mechanical force which is hundreds of times larger than the normal operation, Under the action of the huge short circuit electromagnetic force, many components such as the winding of the transformer may be damaged. This paper describes the whole process of of 2# main transformer in Fushun SiShui substation accident analysis, and the turn-to-turn short circuit accident of the winding is caused by interphase short circuit of the cable, this also provides a scientific basis for the transformer's fault detection.
