Saving energy, lowering energy consumption and reducing pollutants discharge was an important factor of effecting economic development. This is a new research direction to use super capacity to crane system. In this paper, the character of the super capacitor was firstly introduced and analyzed. Secondly, the DC-DC converter used in crane system based on mix power was designed. And the technology...
With the development of large scale integrated circuit technology and computer technology, that using a microprocessor as the core microcomputer of excitation thyristor converter will become the main development of thyristor converters in the future. This paper introduces the features of dsPIC30F6011, and focuses on the structure and function of the intelligent detection and control modules in the...
According to ASTM and DIN international standard and other equivalent GB standards, we finished a lot of experiments on physical chemical properties and electric performance of EHV transformer oil. Based on the experiments data, Kelamayi EHV Transformer Oils are compared with SHELL Diala oil. Domestic Kelamayi oils, which typed KI50AX and KI50GX are blended with SHELL Diala oil in different ratios...
According to ASTM and DIN international standard and other equivalent GB standards, we finished a lot of experiments on physical chemical properties and electric performance of EHV transformer oil. Based on the experiments data, Kelamayi EHV Transformer Oils are compared with SHELL Diala oil used by EHV Power Transmission Co. Aiming at the special characteristics of EHV Transformer Oils, oil-flow...
