摘要

针对一起750 kV变电站66 kV干式空心并联电抗器接地扁铁及混凝土基础发热故障

为了准确分析发热原因并采取对应措施

首先利用红外测温手段识别并确定发热源

接着通过更换接地系统金属材质、分析电抗器基础结构、开展基础内钢筋导通性能测试、进行电抗器接地系统仿真计算

综合分析环流致热和涡流致热影响

明确了发热原因并提出对应措施。最后得出导磁性材料在磁场中产生涡流是电抗器接地扁铁发热的原因

筏板内部钢筋存在金属环形成环流是电抗器基础发热的原因。

Abstract

Regarding the earthing system and foundation heating problem of 66 kV dry-type hollow reactor in a 750 kV substation

in order to accurately analyze the reason and take corresponding measures

firstly infrared temperature measurement was used to identify and determine the source of heat

then

we replaced the grounding system metal

analyzed structure of the reactor infrastructure

tested the conducting performance of steel reinforcement inside the foundation

simulated the earthing system of the reactor

analyzed the effects of circulation heating and eddy current heating comprehensively

the causes of fever were identified and corresponding measures were put forward. Finally

it was concluded that the eddy current of the conductive material in the magnetic field was the cause of the heating of the flat iron grounded in the reactor

the heating of the reactor base was caused by the metal ring in the raft.
