- 摘要：The mechanism of the inrush current generation is analyzed,the
relationship between inrush current and magnetic chain, closing angle,
closing resistance is derived by means of mathematical method,and the
formula of the optimal closing phase is obtained. The principle of
closing resistance to suppress inrush current is expounded. The
combination of closing resistance and phase-control technology is
proposed, which makes the effect of inrush current suppression to the
best. Then, the simulation model of three-phase transformer system was
established by using ATP transient simulation software. The simulation
and analysis of value and working time of closing resistance, and
phase-controlled switching are carried out,and the best scheme to
suppress the inrush current is obtained. At last,through the three-phase
transformer no-load closing test to verify the best closing phase of the
rationality. It is instructive to reduce the closing inrush current of
no-load transformer.
