Method for performing optical fiber channel check without power outage on intelligent substation

一种智能变电站不停电进行光纤通道检查的方法

Abstract

本发明涉及一种智能变电站不停电进行光纤通道检查的方法,其包括直采回路中:电流合并单元处接入第一光纤分路器,分出两根光纤通过法兰连接到第二光纤分路器,然后接入智能变电站的智能保护装置,进行光纤通道检查时,断开第一光纤分路器和第二光纤分路器之间的任一根光纤,将断开光纤的两个接头接入光纤通道检查装置;直跳回路中:智能终端处接入第三光纤分路器,分出两根光纤分别通过法兰连接到第四光纤分路器,然后接入智能变电站的智能保护装置,进行光纤通道检查时,断开第三光纤分路器和第四光纤分路器之间的任一根光纤,将断开光纤的两个接头一并接入光纤通道检查装置;本发明进行光纤通道检查时,不用一次设备停电。
The invention relates to a method for performing optical fiber channel check without power outage on an intelligent substation. The method comprises the following steps: in a direct sampling loop, accessing a first optical fiber splitter to a current combining unit, separating two optical fibers to connect to a second optical fiber splitter through the flanges, and then accessing to an intelligent protecting device of the intelligent substation, disconnecting any optical fiber between the first optical fiber splitter and the second optical fiber splitter when preforming the optical fiber channel check, accessing two splices of the disconnected optical fiber into an optical channel check device; in a direct tripping loop, accessing the third optical fiber splitter to the intelligent terminal, separating two optical fibers to respectively connect to the fourth optical fiber splitter through the flanges, and then accessing to the an intelligent protecting device of the intelligent substation, disconnecting any optical fiber between the third optical fiber splitter and the fourth optical fiber splitter when preforming the optical fiber channel check, concurrently accessing two splices of the disconnected optical fiber into the optical channel check device. By use of the method disclosed by the invention, the power outage of the primary equipment is unnecessary when performing the optical fiber channel check.
