一种弧光单元

Arc light unit

Abstract

The utility model relates to an arc light unit. The arc light unit comprises arc light probe interfaces, fiber interfaces, device alarm dry contacts, a device power supply terminal, a grounding terminal and signal indication lamps. The arc light unit is connected with arc light probes through the arc light probe interfaces. A shift regulator is further arranged on the panel of the arc light unit. Each arc light unit can access to 16 arc light probes. A system expansion function is thus realized. The fiber cost can be saved. The arc light unit acquires motion information from the arc light probes and sends the information to a main control unit. Timely maintenance and fault removal can be facilitated.
本实用新型涉及一种弧光单元,采用以下技术方案:包括弧光探头接口、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,弧光单元通过弧光探头接口和弧光探头连接。弧光单元的面板上设有档位调节器。本实用新型采用了弧光单元,每个弧光单元可接入16个弧光探头,实现了系统的扩展功能;而且可以节省光纤的费用;弧光单元收集来自弧光探头的动作信息并传送给主控单元,有利于及时检修和排除故障。
