高压直流电源的控制与监测

Control and Monitoring of High Voltage DC Power Supply

高压直流电源为高压柜二次控制回路提供直流控制电源,设置有电池组和电压调节装置,输出电压、电流稳定,可保证高压柜二次回路的操作、继电保护、控制可靠。首钢京唐公司选用的直流电源是模块化和智能化的高频开关直流电源,整流部分为IGBT,将输出的电压和电流反馈信号作为PWM脉宽调制的信号,通过调整PWM脉冲宽度控制输出电压值,使其更快更有效。此外,简单、多样的操作界面方便用户进行设置,也便于监控各类信息。

High-voltage DC power supply provides DC control power for secondary control circuit of high-voltage cabinet,which is equipped with battery pack and voltage regulating device. The output voltage and current are stable,which can ensure the operation,relay protection and reliable control of the secondary circuit of the high voltage cabinet. The DC power supply selected by Shougang Jingtang Company is a modular and intelligent high frequency switching DC power supply. The rectifier part is IGBT. The output voltage and current feedback signals are used as PWM pulse width modulation signals. The output voltage is controlled by adjusting the PWM pulse width to make it faster and more effective. In addition,simple and diverse operating interfaces are convenient for users to set up and monitor all kinds of information.
