Description

一种弧光扩展器
技术领域
 本实用新型涉及一种弧光扩展器。
背景技术
中、低压母线发生短路故障时，所产生的电弧光对设备及人员会造成极大的伤害。但是目前在国内中低压母线系统中，检测点少，扩展功能不足，而且可能导致故障切除时间的延长，造成事故进一步扩大，威胁到系统的稳定运行。
发明内容
 针对上述问题，本实用新型提出一种弧光扩展器。
本实用新型采用以下技术方案：包括弧光单元接口、光纤接口、装置报警干接点、装置电源端子、接地端子和信号指示灯，弧光扩展器通过弧光单元接口连接弧光单元。每个弧光扩展器可接入8 个弧光单元，可增加8×16=128个检测点，实现系统的扩展功能。
弧光扩展器与弧光单元之间通过高速FPGA 芯片实现数据传送。
本实用新型的有益效果是：采用本实用新型，每个弧光扩展器可接入8 个弧光单元，可增加8×16=128个检测点，实现系统的扩展功能。弧光单元、弧光扩展单元采用高速FPGA 芯片完成数据转发功能，由于转发所带来的延时对于保护系统的性能没有影响。 
附图说明
图1为本实用新型的结构示意图，
图中：1、装置报警干接点，2、装置电源端子，3、光纤接口，4、接地端子，5、弧光单元接口，6、信号指示灯。
具体实施方式
包括弧光单元接口、光纤接口、装置报警干接点1、装置电源端子2、接地端子4和信号指示灯6，弧光扩展器通过弧光单元接口5连接弧光单元。每个弧光扩展器接入8 个弧光单元，这样就增加了8×16=128个检测点。弧光扩展器与弧光单元之间通过高速FPGA 芯片实现数据传送。
