Study On The Reconstruction And Maintenance Of Power Transformer

As the junction of transimmting and distributing power, the power transformor is at the core of power network, so it's reliability works on power energic quality for amoutful consumers, and the safety of power system even. The health of power transformor depends on not only design and manufacture, frame and stuff, but also overhaul and maintenance. These two sides are probed into in this thesis.Firstly, to reconstruct thin-insulated transformors, this thesis discusses exclusively the design principle and calculating method of transformers, analyzes earnestly the relationship of it's performance parameters, advances the thinking or routine of resolving questions, puts forward credible measures, and favorable benefits present after reconstruction.Secondly, to diagnosticate pinpointedly and manage promptly transformors' defaults, in combine to instances, this thesis summarizes the character and manage of those defaults resulted from improper maitenace or overload, summarizes the character and manage of those defaults resulted from multipoint ground, specialy dissertates the measuring routine of and the routine of.At last, to improve transformors' health, this thesis sets forth synthetical poliy in example of DFM, expressly suggest that much attention be payed to relay's reliability, automatic reclose, etc.
