金盆水电站微机保护装置的研究

微机保护装置搭载集成度高、总线排布芯片PLC、高灵敏度电流、电压互感装置、绝缘性能好的出口中间继电器、可靠性能高的开关、电源模块等电器元件构成。微机保护装置主要用于220kV及以下电压等级的发电厂、变电站、配电站等,也可用于部分(70~220)V电压等级系统中的电压、电流的保护及测量控制。

The microcomputer protection device is composed of electrical components such as high integration,bus arrangement chip PLC,high sensitivity current and voltage mutual inductance,export intermediate relay with good insulation performance,switch with high reliable performance,power supply module and so on.The microcomputer protection device is mainly used for power plants,substations and power distribution stations with voltage levels below 220kV,and can also be used for voltage and current protection and measurement control in some(70~220)V voltage grade systems.
