摘要
针对于传统煤炭型静电除尘器电源系统反应效率低、设计周期长、安全性差等缺点,设计了一套基于Verilog静电除尘电源调压系统。该工作电源系统使用LC组件、硅整流桥组和升压变压器以达到除尘器的工作电压。反馈系统采用电子设计自动化技术,用硬件描述语言完成对反馈系统的设计,并在仿真平台上完成控制芯片现场调试,当电压大于临界电压时,通过改变L-C器件的数目使其持续稳流。经试验测定,该控制系统能够精准地反馈出除尘器电压信号的变化情况,反馈响应更快、精度更高、监控性能更好,同时抗干扰能力优于其它控制系统。
Aiming at the characteristics such as low reaction efficiency, long design period, and poor security of the power system in traditional coal-type electrostatic precipitator, this paper has designed a set of voltage-regulating systems on the basis of the power of Verilog electrostatic precipitator. This working power supply system utilizes LC component, silicon rectifying bridge, and set-up transformer, to reach to the working voltage of the dust precipitator. By adopting the electronic design automation technology, the feedback system completes the design through hardware description language, and completes the on-site commis- sioning of the control chip on the simulation platform. When the voltage is larger than the critical voltage, the continuous steady flow can be maintained through changing the quantity of L-C component parts. Through test and examination, it determines that： this control system can accurately feedback the change of voltage signal for dust precipitator, and its feedback features fas- ter response, higher accuracy, and better control ability. Meanwhile, its capacity of resisting disturbance is better than other control systems.
