配电保护

简介

MicroLogic X 控制单元设计用于提供过流和接地故障电流保护。

描述

选择保护特性时应考虑以下各点：

  • 过载电流（过载和短路）和潜在接地故障电流

  • 需要保护的导体

  • 设备之间的协调和选择性

  • 是否有谐波电流

保护特性可通过脱扣曲线表示，它说明断路器脱扣时间与测量的电流和保护设置的函数关系。保护设置在 MicroLogic X 控制单元的额定电流 In 上标示。

额定电流 In

保护设置范围取决于额定电流 In，这个值由插入到 MicroLogic X 控制单元的互感器插头定义。

用户不能更换或修改互感器插头。联系您的 Schneider Electric 服务代表检查、更换或重新连接传感器插头。机械失配保护可防止安装的互感器插头不兼容断路器壳架等级。

对于 IEC 标准的断路器，可用的互感器插头产品如下表所示。
