摘　　要：针对传统信号报警装置可靠性差、接线复杂、集成度低、体积大、报警方式单一等缺点,设计了一种适用于气体绝缘金属封闭开关设备(GIS)的集中信号报警器,实现了多路报警信号集中采集、故障准确定位、多种报警形式输出、报警信息远程传送等功能。该装置硬件结构简单、集成度高、可靠性好,具有较高的实用性。The traditional signal alarm device has a lot of disadvantages such as less reliability,complex wiring,low integrated level,big volume,and single alarm mode.For these reasons,a kind of centralized signal alarm device is designed for gas-insulated mental-enclosed switchgear（GIS）.This device implements the functions such as centralized collection of multichannel alarm signals,accurate positioning of faults,output of various alarm modes,and teletransmission of alarm information.And the computational results indicate that the device has a simpler hardware construction,high integrated level,better reliability,and higher practicality.
