文章最后借助MATLAB电力工具箱进行了变压器空载合闸和合闸于故障的仿真试验，通过对不同情况的仿真，对原理进行了验证。
In this paper, some simulations of transformer are done when no-load closing under different conditions by using MATLAB. Results of the simulations also proved the priority of this principle.
空载合闸作为变压器最常见的操作之一，随着操作次数的增多，其暂态过程也将给电力系统带来越来越严重的影响。
The no-load closing as one of the most common operations to transformer, its transient processes will bring more and more serious influences to power system with the number of operations increases.
