Disciplinary inspection supervision helps OPGW optical cable "heterogeneous" risk control

On September 20, the disciplinary inspection personnel of the State Grid Shaoxing Power Supply Company conducted a supervision and inspection on the on -site of the 220 kV Tiger Corporation 2465 and the Gutai 4Q81 line OPGW Line 220 kV tiger. The OPGW optical cable does not have "heterogeneous" set up hidden dangers and register information.

OPGW's full name of the overhead floor composite optical cable is both the transmission line ground line and the power communication optical cable. It plays an important role in the main power network and the power communication network, which is directly related to the safe operation of the power grid. However, OPGW does not necessarily be laid to the end with the end of the power line, and there is a phenomenon of "heterogeneous". In the infrastructure, technical reform, and large -scale construction of power lines, if the "heterogeneous" phenomenon is not clear, the OPGW optical cable may be disrupted by mistake. Big risk hidden dangers.

Earlier this year, the State Grid Shaoxing Power Supply Company launched the special work of risk management and control of the OPGW optical cable "heterogeneous". The company's disciplinary inspection personnel actively follow up the supervision, focusing on whether the "heterogeneity" of the OPGW optical cable "heterogeneous" is fully covered, the inspection process has false situations such as confused passage, false reports, etc. Strictly account for accountability. By giving full play to the joint effort of "disciplinary inspection+communication majors", the company will survey and collect data for visual translation, creatively complete the transmission line and OPGW "one picture" quick check table, providing operational and maintenance, design and construction units with more intuitive understanding and understanding The chart reference has made multiple confirmations in all aspects of the infrastructure technical reform project involving OPGW, which greatly reduces the risk of non -planned interruption of optical cables. Through the preparation of "one picture", the company promptly corrected the misjudgment of OPGW multiple times to achieve the effect of early filing and prevention of misjudgment.

As of now, the company has completed the arranging of the 3,000 -kilometer OPGW optical cable, and has registered for the 500 kV Zhushun line and 220 kV phoenix dual -line OPGW "heterogeneous". Next, the company's disciplinary committee will continue to improve the supervision and feedback work mechanism, urge relevant responsible departments to pay close attention to key links such as OPGW construction planning and consolidating basic data updates to further improve the level of operation and maintenance management of OPGW, and achieve the goal of 100%of the business guarantee rate. To ensure the safe and stable operation of the power grid, laid a solid foundation. (Xu Liping Zhu Hang)
