户外高压隔离开关存在的问题和改进措施

由于大气污染、制造工艺、维护管理等因素的影响,隔离开关在运行中存在锈蚀严重、传动不到位、接触不良、瓷瓶断裂、密封不好等问题,这些问题处理不好,将威胁电力安全生产,为此,提出了加强隔离开关管理的措施及提高隔离开关可靠运行的技术改造措施,尽量避免设备带缺陷运行。

The Faults and Improvement of Outdoor High-voltage Disconnecting Switch

Due to the factors-air pollution, manu- facturing engineering, maintenance and management, and so on, some problems, such as serious erosion, failure to reach the designated place, unclosed contact, insulator breaking and poor sealing, occur in operation. If these problems are not treated properly, they will threaten the safety of production. In view of this, the paper puts forward some countermeasures to reinforce the rnanagement of disconnecting switch and to improve its reliability to avoid the apparatus operating with its faults on.
