| Abstract: |
| Mathematical models are established for the contact system of CPS(Control & Protection Switch) and the arc movement, based on which, the short circuit current is simulated and calculated. The simulative results coincide with the experimental results quite well. The model of main circuit conductors and cable lines is established in Maxwell simulation environment, based on which, the distribution of transient space electromagnetic field around the communication circuit is simulated and the induced voltage and current are further calculated, according to which, suggestions on the design of low-voltage apparatus are given. |
