In recent years, the new type design of current transformer with bushing structure has been widely used in distribution network system due to its advantages miniaturization, high mechanical strength, maintenance-free, safety and environmental protection. The internal temperature field is an important characteristic parameter characterize thermal insulation aging performance transformer, mainly ...

Plain bearings are an important part of many large and critical units assemblies used in the mining industry. They widely power equipment, powerful pumps, compressors, electric motors internal combustion engines (ICE). usually include anti-friction bushing, shaft surface (bearing journal) oil layer between them. These complex parts which dangerous defects may occur directly affect durability, a...

At present it is claimed that all electrical energy systems operate with high values of efficiency and reliability. In electric power (EPS), distribution transformers are responsible for transferring the from stations up to load centers. Consequently, mandatory design possess highest reliability possible. Considerable losses hotspots may exist in bushing region a transformer, where conductors p...

Distributed-drive electric vehicles constitute an important research direction for the future development of vehicles. In this regard, integrated suspension wheel-side drive system has considerable potential because it can address lack driving smoothness and grounding deterioration caused by excessive unsprung mass distributed-drive system. However, a complete systematic description design such...
