The electromagnetic radiation elimination device of electronic equipment has the right to
ApplicationNo.: 200920 175759.8 Application Date: 2009-09-0 1.
An electromagnetic radiation elimination device for electronic equipment consists of a neon lamp DS 1, a resistor R2, a stationary contact M, a detection switch S 1, a signal analysis control circuit IC 1 and branches R4, C5, R5 and C6 connected between an E line and N and L through a contact K 1. When the detection button S 1 is pressed, the signal will be transmitted to the Q 1 phototransistor and then to the IC 1 for identification. The state of K 1 is controlled by R6 and Q2, and the E line is connected to the zero line N or L. At the same time, the working state is displayed by R8 and LED D4. The circuit can quickly identify the zero line and live line of power supply, and make its zero line contact with computer ground through resistance and capacitance. Ensure that the electromagnetic shielding of the computer works normally, eliminate radiation, and the circuit itself has overvoltage protection function to prevent the computer from being damaged by overvoltage.
