农村10kV配电变压器常见故障分析及防范

Analysis and Prevention about Destruction Fault on 10 kV Distribution Transformer in Rural Power Network

农村配电变压器损坏时有发生。为了减少配电变压器故障机率、提高农村电网供电可靠性,就配电变压器常见的故障类型及故障原因进行分析,找出避免和解决配电变压器故障的直观方法,提出必须进行变压器特性试验及综合分析,才能准确可靠地找出故障原因。同时,要重视运行前的测试和运行中的维护,以减少变压器的故障机率。

Faults of distribution transformer widely exist in rural power network. For reducing the fault rate of distribution transformer and improving the reliability of power apply, fault type and fault cause of distribution transformer were analyzed, direct method of preventing fault is found, and the advice that finding fault cause must rely on character testing and integrate analysis of distribution transformer was put forward. At the same time, the measure of reducing fault rate is test of transformer before running and run maintenance.
