Abstract: Introduction was made to the working principle of electromagnetic force machine and the characteristics of fast load switch.This paper gave the design calculation of 20 kV fast load switch. On the basis of drawing on the existing development experience of electromagnetic force machine, each key design parameter was analyzed and the key point of 20 kV fast load switch was raised and successfully put in practice. This paper raised solution idea to manufacture the higher voltage grade fast load switch.
Key words: fast operation; fast load switch; electromagnetic force; insulation structure; mechanical life
