On Enhancement of Anti-jamming Ability of High-frequency Protection

WU Tie-jun(Qingyuan Power Supply Bureau,Qingyuan,Guangdong 511515,China)  
In view of the anti-jamming question of high-frequency protection,the paper first analyzes the high-frequency channel of high-frequency protection,the generation and intruding means of lightning waves and other traveling waves,thus discriminating different characteristics among high-frequency signals,lightning waves and other traveling waves.It proposes to connect the serial codirectional double-winding reactor to the ends of radio cable,clip the range of fall and peak of the lightning waves and other traveling waves,and reduce the shock effects of lightning waves and other traveling waves on the transceiver,in order to further enhance the anti-jamming ability of high-frequency protection.
