| Abstract: | Along with the coal mine enterprise energy-saving emission reduction awareness continues to improve, the inverter is widely used in electrical equipment in coal mine. A lot of harmonics will generate harmonic inverter during running, will greatly interferes the weak signal transmission. Through the inverter to the KJ90 NB coal mine safety monitoring system to produce interference analysis,proposed solutions, the security monitoring signal transmission application of anti interference technology of frequency conversion. After the trans formation of KJ90 NB coal mine safety monitoring system is of good performance, stable, safe, reliable operation of the system. |
