市政给排水工程10kV配电系统保护配置

10kV Distribution System Protector of Municipal Drainage Work

市政供水厂或污水处理厂作为重要的市政设施,必须保证其供电的安全可靠。继电保护装置是保证安全供电的重要工具,它能够在供电系统出现故障时迅速、准确地切除故障元件,因此合理的配置继电保护、正确计算整定值具有重要意义。本文结合工程实例,介绍了市政水厂或污水处理厂10kV变电所继电保护配置及整定的方法,对工程设计起到一定的参考、借鉴作用。

Municipal water supply plant or sewage treatment plant must ensure their safe and reliable power supply.The relay protection is an important tool to ensure safe power supply,which can quickly cut off trouble elements when faults happens in the power supply system.So it is important to equitably dispose relay protection and correctly calculate the setting values.The paper combines engineering example to present the relay protection collocation and setting method of 10kV transformer for the municipal coater supply plany or sewage treatment plant,which has some refereace and the use for reference for the engineering design.
