Arc explosion accidents in live working seriously threaten the safety of power workers. At present, mainstream arc protective clothing material is aramid and blends aramid. However, will produce toxic gas under high temperature combustion, which harmful to health operators. Therefore, it a special challenge study fabrics that are friendly human body have highly performance protect electrical Polyimide nontoxic has excellent resistance, flame retardation, mechanical properties. In this paper,...
Arc discharge accidents in industrial applications pose an enormous threat to workers and surrounding equipment. To study the effect of electrode materials on arc energy parameters provide a theoretical basis for selection protection when different engineering environments. This article established experimental platform measurement system based IEC 61482–1 standard. tests were conducted four materials: copper, stainless steel, iron, graphite under test conditions. The results show that...
High voltage circuit breaker (HVCB) is the most important control and protection equipment in power system. The mechanism of HVCB relatively complex, probability failure large. If occurs, safe stable operation entire system will not be guaranteed, which cause huge economic losses. Due to complexity traditional monitoring diagnosis methods, information obtained comprehensive enough, leads insufficient precision affects results. In order determine fault characteristics categories simply...
Abstract Due to its significant attributes, the liquid metal current limiter (LMCL) is considered a new strategy for limiting short-circuit in power grid. A resistive wall (RWLMCL) designed advance starting current-limiting time. Experiments are performed investigate dynamic behaviors of metal, and influence different currents on self-shrinkage effect compared analyzed. Furthermore, mathematically modeled, reason formation arc plasma obtained by simulation. The laws transfer cavity revealed,...
The arc energy generated during the operation of a vacuum circuit breaker not only affects its work life, but also breaking performance. mainly depends on fault current level and duration, electrode material will affect energy. To study effect different materials parameters, including temperature. In this paper, test platform was built according to IEC 61482-1-1 61482-1-2, carried out four under conditions. results show that lead currents, which iron produces largest graphite smallest....
Power transformer is the key equipment in power system. The oil temperature an important factor affecting service life and load capacity of immersed transformer. Applying big data technology to prediction system can more reliably efficiently evaluate thermal characteristics Therefore, based on Hadoop + spark platform its ecological components, this paper uses convolutional neural networks (CNN) other algorithms compare, predict long-time series at top final results show that: CNN algorithm...
