根据高压悬浮电选机分选电场的特点,从改进悬浮电选机电源结构入手,采用LC回路提高电源自适应能力,加大恒流输出和反馈控制,设计了一种恒流高压直流电源系统,该系统对高压直流采用自动稳定性控制,提高了电源电压的稳定性和抗干扰能力,形成了较稳定的电晕电场,减轻了电晕电极间空气电离击穿现象,提高了工作电压,降低了控制难度。经过生产实践,获得了良好的分选指标。
According to the characteristics of the electric field of high voltage suspension electric separator, this paper starts with improving the structure of the power supply of suspension electric separator, using LC loop to improve the adaptability of power supply, increasing the constant current output and feedback control, and designing a constant current high voltage DC power supply system , The system uses automatic stability control of HVDC to improve the stability of the power supply voltage and anti-interference ability to form a more stable corona electric field, reducing the ionization breakdown of the air between the corona electrodes and raising the operating voltage, Reduce the difficulty of control. After production practice, access to a good sorting index.
