油浸式有载分接开关触头磨损烧蚀模拟及验证
Simulation and verification for wearing and ablated contacts of oil-immersed on-load tap changers
摘要
Abstract
The on-load tap changer(OLTC)is a critical device for regulating the output voltage of transformers,and it is also one of the most failure-prone components within it.Currently,the core-lifting detection method traditionally used for OLTC fault diagnosis is costly,time-consuming,and inflexible.This article introduces a simulation method for static contact defects in M-type oil-immersed composite OLTCs,exemplified by contact wear and erosion.The feasibility of this simulation method is verified through dynamic resistance waveform testing on actual OLTCs.This method is practical and has typical time-domain characteristics of dynamic resistance waveforms associated with specific defects,thus offer-ing a valuable direction for the maintenance of OLTCs.关键词
