Abstract

一种联机无源控制信号装置。它主要是解决现有主备馈电开关在联机后若不切断其通讯线则停机状态的开关将无法实施停机检查等技术问题。其技术方案要点是:控制开关的无源控制信号线路上连锁并联主开关编程器和备用开关编程器。主开关编程器采用编程器PLC,并设置有2个主控切断触头和1个主控备触头三个输出端;备用开关编程器采用编程器PLCD,并设置有2个备控切断触头和1个备控主触头三个输出端。它能通过程序控制实现主开关与备用开关联机后切断控制线路上的电源,使开关切换后停机状态的开关保持无电,以方便维修和维护。它可广泛应用于井下风机控制开关的控制信号线路上。

Description

联机无源控制信号装置
技术领域
本实用新型涉及一种用于井下风机控制开关的控制信号线路上的联机无源控制信号装置。
背景技术
目前,用于井下风机控制开关的控制信号线路上的主开关与备用开关联机通讯线路存在24伏信号电源,即有源控制或称有电源控制,但此电源在联机后若不切断则停机状态的开关将无法开机检修,因为在矿山采掘面很容易发生事故,故存在隔爆问题。
发明内容
本实用新型的目的是提供一种用于井下风机控制开关的控制信号线路上、可通过程序控制实现主开关与备用开关联机后切断控制线路上电源的联机无源控制信号装置。
本实用新型解决其技术问题所采用的技术方案是:控制开关的无源控制信号线路上连锁并联主开关编程器Ka和备用开关编程器Kb。主开关编程器Ka采用编程器PLC,并设置有2个主控切断触头K1、K2和1个主控备触头K3三个输出端;备用开关编程器Kb采用编程器PLCD,并设置有2个备控切断触头K4、K5和1个备控主触头K6三个输出端。
本实用新型的有益效果是:它能通过程序控制实现主开关与备用开关联机后切断控制线路上的电源,使开关切换后停机状态的开关保持无电,以方便维修和维护。它可广泛应用于井下风机控制开关的控制信号线路上。
附图说明
图1是主开关与备用开关通讯联络线路隔离控制电路示意图
具体实施方式
在井下风机控制开关的无源控制信号线路上连锁并联主开关编程器Ka和备用开关编程器Kb。主开关编程器Ka采用编程器PLC,并设置有2个主控切断触头K1、K2和1个主控备触头K3三个输出端;备用开关编程器Kb采用编程器PLCD,并设置有2个备控切断触头K4、K5和1个备控主触头K6三个输出端。当主开关编程器Ka故障停机时,输出信号使备用开关编程器Kb工作即备控主触头K6闭合,2个主控切断触头K1、K2断开,备控切断触头K4、K5闭合;相反,当备用开关编程器Kb故障停机时,输出信号使主开关编程器Ka工作即主控备触头K3闭合,备控切断触头K4、K5断开,主控切断触头K1、K2闭合。它是通过程序控制实现主开关与备用开关联机后切断控制线路上的电源,使开关切换后停机状态的开关保持无电。参阅图1。
