The utility model discloses a device capable of remotely monitoring and controlling the switching of remote control channels in substations, which belongs to the field of substation communication. The device consists of eight linked switching relays (1). Each switching relay (1) has three pins, which are the middle pin and the upper and lower pins. The middle pin connects the tele-motor network (2) of the tele-motor (7), and the upper and lower pins connect the dual-channel network line of the main station, namely the A-channel network line (3) and the B-channel network line (4) of the main station tele-control respectively. The state of the switching relay (1) is transmitted to the main station (5) via a network line (6) through a 2M dedicated communication channel and receives the command issued by the main station (5). The utility model has the function of remote communication. The relay state is sent to the main station through a 2M special communication channel, and the remote control command issued by the main station is received to realize the remote switching function of the remote control channel.
【技术实现步骤摘要】
一种可远程监视及控制变电站远动通道切换的装置
本技术涉及一种可远程监视及控制变电站远动通道切换的装置,属于变电站通信领域。
技术介绍
随着无人值守变电站的普及,远程监视与控制发挥重要作用,是调度值班人员的了解变电站设备运行情况的直接手段。作为远程监视与控制的基础设备远动机及其通道经常由于各种原因导致远动通道通信中断,不能继续发挥远程监视与控制功能。常规处理方法在值班员通知运行维护人员后,维护人员接到通知后联系驾驶员,再与驾驶员汇合后赶赴变电站进行消缺。整个过程需要花费大量的时间,近的变电站需要花费1小时,远的变电站需要花费4小时,不能及时恢复通信,导致变电站失去监控,影响电网安全稳定运行。
技术实现思路
有鉴于此,本技术的目的是提供一种可远程监视及控制变电站远动通道切换的装置,该装置包含8个联动的双位继电器,每个继电器的中间引脚连接远动装置通信网线,上下引脚分别连接主站双通道网线,通过对CPU编程实现对这8个继电器的控制。该装置具备远程通信功能,将继电器状态通过2M专用通信通道上送至主站,并接收主站下发的遥控命令,实现对远动通道的远程切换功能。本技术的目的是通过以下技 ...
