摘要
为了防止干式电抗器接地扁铁发热引起的不利影响,通过红外测温对新疆某66 kV干式电抗器接地扁铁跟踪测温,分析由漏磁、环流等原因引起的发热缺陷。针对这些缺陷提出应注意的事项及防范措施。实践结果表明打开由于在电抗器漏磁范围内存在不被允许的闭合环路能从根本上解决环流发热的问题。
In order to prevent the adverse effect caused by the overheat of dry reactor grounding fiat iron, the paper carries out the track temperature measurement for a 66 kV dry reactor grounding fiat iron through infrared thermometry, and analyzes the overheat defects caused by magnetic flux leakage, circulation and so on. In view of these defects, the paper puts forward the cautions and preventive measures. Practice resuhs show that opening closed loop, which is not allowed to exist in the range of reactor magnetic flux leakage, can fundamentally solve the problem of heat circulation.
