Abstract

In the primary and secondary integrated switch, the distance between the primary equipment and the secondary equipment is very close. When transient processes such as switching operation and lightning impulse occur on the primary side, transient electromagnetic disturbance will occur on the secondary equipment, which will affect its normal operation. In this paper, a 75kV1.2/50us lightning impulse experiment of a 12kV primary and secondary integrated switch is carried out, and the induced voltage of the corresponding spatial electromagnetic field in a single-turn circular loop with a diameter of 15cm is measured. The results show that it is a damped oscillation wave with a peak value of 200V and a main frequency 8.1MHz. Through the test results of induction voltage, it is recommended that the shielding effectiveness of a shielding box enclosing the secondary equipment should be greater than 36.5dB, to ensure the normal operation of the secondary equipment. The shielding box is simulated, and the effects of operating frequency and hole size on shielding effectiveness for time-harmonic magnetic field are shown.
