GE IS215VPROH1B 独立三重冗余超速保护模块
IS215VPROH1B 是 GE Speedtronic Mark VI 经典涡轮控制系统专用独立三重冗余超速保护核心板卡(VPRO 保护组件)。整套机组保护单元采用三块 VPRO 板(R8/S8/T8)三冗余架构,独立于主控调节系统运行,搭配 TPRO 测速端子板、TREG 跳闸继电器端子板配套使用,负责燃气轮机、蒸汽轮机独立安全保护逻辑,是机组紧急停机 ESD 的核心安全硬件,广泛应用于火电联合循环、燃气电站、炼油透平机组。
模块采用双层堆叠 PCB 结构(底板 + IS200VPRW 上层子板),搭载独立处理器、测速采集回路、跳闸继电器驱动回路与 IONet 以太网通讯接口,不依赖主控 CPU 即可独立完成超速、超温、停机保护运算,实现安全保护与常规控制硬件物理隔离,规避主控故障导致保护失效风险。
