SF_6电流互感器的故障原因及预防性措施

The fault causes and preventive measures of SF_6 current transformer

SF_6电流互感器在运行中发生故障的主要原因是设备材料和零、部件的制造及装配质量不良,不当的运输和吊装也会给SF_6电流互感器留下故障隐患。为了有效地防止SF_6电流互感器故障的发生,生产厂家应选择质量优异的材料和零、部件,加强工艺管理,并严格进行检验,提高设备的制造水平。设备的运输应严格按照相应的技术标准进行。运行单位则应加强设备的交接验收,定期开展设备的预防性试验。

The main fault ca uses of SF6 current transformer in the operation are due to the poor quality of the manufacture and installation for equipment material and parts. Improper transportation and suspension installation also leave behind hidden trouble for SF6 current transformer. In order to prevent SF6 current transformer accident happening, the manufacturer should select good quality material and parts, strengthen the technique management, test strictly, improve equipment manufactureing level, transportat the equipment according to the corresponding technological standard. The operating unit should strengthen the accepting and checking management of the equipment, and develop the preventive test for the equipment regularly.
