抑制电压暂降对电仪设备扰动影响

Suppressing the disturbance of voltage sag on electrometer equipment

从系统侧和设备侧着手,按照4道防线要求采取不同的抑制和预防措施,着重解决电压暂降对电仪设备扰动影响。通过优化系统运行方式,安装电源自投切换装置,降低电气设备故障,提高和完善继电保护及自动装置的配置标准,完善仪表UPS电源双回路及无扰动切换,对电动机智能保护器保护参数进行合理设置,安装抗晃电模块等措施,确保供电可靠性,为装置安全、平稳运行提供有力保障。

Four defense lines were organized for the system and for the equipment,and different measures were taken to suppress and prevent the disturbance of voltage sag on electrometer equipment.By optimizing the operation mode of the system and installing an electrical source auto-switch device,electrical equipment faults reduced.The configuration of relay protection and automatic device were improved and perfected.The double circuit and undisturbed switch of UPS power supply for instrument were perfected.The parameters of the intelligent protector of motor were reasonably set.An anti-voltage sag module was installed.Therefore,the reliability of power supply was ensured to provide a strong guarantee for the safe and stable operation of the device.
