配电变压器常见故障分析

配电变压器的运行条件一般都比较简陋,露天放置且要经受高温、严寒、风吹日晒的考验,尤其是在高原地区的使用过程中,经常会出现音响较大而嘈杂,这可能是变压器铁芯的问题;变压器在负荷和散热条件、环境温度都不变的情况下,较原来同条件时的温度高,并有不断升高的趋势,是变压器温度异常升高所致,这与超极限温度升高同样是变压器故障象征事故,现就其故障现象、形成原因及预防措施简要分析。

Analysis of the Common Faults of Distribution Transformer

Distribution transformer operating conditions are generally relatively simple and crude. Open-air laying place must withstand the test of heat, cold, wind and sun. Especially in the plateau region,whick often appear larger and noisy sound may be the problem of transformer iron core; transformer in the load and thermal conditions, the ambient temperature were unchanged compared with the original with the conditions, the temperatures are high, and a rising trend as well as abnormal temperature rise transforme...
