HGIS在户内敞开设备改造工程中的应用研究

Application Research of HGIS in Indoor Open Equipment Reconstruction Project

随着电网建设的不断发展,大量20世纪八九十年代建设的变电站在长期运行后进入故障多发期,维护工作量大幅增加。同时,随着工业制造技术的持续发展及技术的不断创新,很多以前大批使用的设备由于技术的更新换代,已逐渐被淘汰,厂家也已停止生产,零配件的缺失进一步加大了维修难度。因此,为了保证电网运行的安全可靠性,近年来,电力公司加大了对老旧变电站的改造力度。本文结合户内变电站110kV敞开式配电装置改造的实施方案,对老旧变电站改造的配电装置选择进行分析比较,并提出合适的方案。

With the continuous development of power grid construction,a large number of substations built in the 1980s and 1990s have entered a period of frequent failures after long-term operation,and the maintenance workload has increased significantly.At the same time,with the continuous development of industrial manufacturing technology,the technology continues to Innovation,many of the equipment used in the past has been gradually eliminated due to the upgrading of technology,manufacturers have stopped production,the lack of spare parts further increased the difficulty of maintenance.Therefore,in order to ensure the safety and reliability of the power grid operation,the power company has intensified the transformation of the old substation in recent years.This paper combined the real implementation plan of the 110kV open-type power distribution unit transformation of the indoor substation to transform the old substation.The device selection was analyzed and compared,and a suitable solution was proposed.
