摘要

Distribution transformer is one of the important electrical equipment in power grid. The working state of distribution transformer directly affects the safe and stable operation of power grid. When distribution transformer during short circuit, the short-circuit force will cause distribution transformer damage. Thus, it is necessary to research the short-circuit force of distribution transformer. In this paper, a three-dimensional model of distribution transformer is established, and compare with the short-circuit forces based on single-phase power and three-phase power short-circuit tests. The results show that the single-phase power short-circuit test of distribution transformer can replace the three-phase power short-circuit test.
