一种新型板材夹钳装置系统设计

　　本实用新型满足当中置接地车推出柜外，投入中熔断+避雷器车时，接地车非工作位置点对本段进线柜和分段柜的可靠二次联锁，从技术层面上彻底解决了传统中置接地车推PT柜、同为中置手车时其辅助点易失效，从而导致五防联锁失效的问题，保证了开关柜的安全可靠运行，具有外形小巧，结构简单，便于安装，五联锁安全可靠等特点。

The process of selecting and designing the major components for a hybrid solar collector/CHP system is described. Particular attention was given to the design of the solar collector and a number of options, including thin membrane heat pipe solar collectors (both ‘normal’ and ‘artery’ types) and hybrid heat pipe solar collectors (both wicked and wickless types), were considered. Performance comparisons were made using theoretical and experimental data and a hybrid solar collector was selected as the best option for the system. Micro impulse-reaction turbine using n-pentane as its working fluid was selected for the system although further work is being carried out on a compressed-gas driven turbo alternator. A prototype hybrid solar collector/CHP system has been constructed and the results of its theoretical and experimental testing are presented in Part II of this paper.

工农业生产和日常生活离不开淡水。在我国西北方和许多沿海工业城市以及严重缺水的地区, 淡水是生命线。虽然海洋面积几乎占地球表面的四分之三, 但是海水中由于含盐量太高, 不能直接应用。
