基于PLC的直流电源充电模块实现自动检测的设计
|
摘要
在电力系统中,直流电源能否可靠运行是变电站安全运行至关重要的保证。高频开关电源充电模块是直流电源重要组成部件,其主要作用是向高压开关柜里的继电保护装置提供不间断的直流电源。文中结合生产运行中高频开关电源模块产品的缺陷发生,提出应用PLC实现自动控制对充电模块进行生产检测的方法。从而,大大提高变电站中充电模块产品质量精度及运行的可靠性。
In the power system,whether the DC power supply can be operated reliably is an important guarantee for the safe operation of substation. The high frequency switch power supply charging module is an important component of DC power supply. Its main function is to provide uninterrupted DC power supply to the relay protection device in the high voltage switch cabinet. In this paper,based on the defect of the high frequency switching power supply module in production operation,the method of automatic control is proposed. Thus,the quality accuracy and operation reliability of charging module in substation are greatly improved.
