摘　　要：为了解可移动式直流融冰装置去掉换流变压器后对装置本体性能和接入系统的稳定性的影响程度,以典型结构和参数的25 MW 6脉动直流融冰装置为研究对象,通过仿真计算,研究了去掉换流变压器对系统电压稳定性、装置交流滤波器、装置绝缘配合和装置融冰性能的影响,结论为:该类型小容量直流融冰装置可以采用不带换流变压器方式运行。For the movable DC de-icing installation,it is a question whether there is any effect of it being without converter transformer on its characteristics and the stability of the system connected with it.The possible effects on the stability of the system as well as the AC filter,insulation coordination,and de-icing capability of the installation are studied in this paper with a 25 MW 6 pulse-circuit DC de-icing installation that has the typical structure and parameters of the movable DC de-icing installation.It is concluded that such small capacity DC de-icing installation is able to work well without converter transformer.
