The effects associated with the displacement of the center of gravity of the solar system under the influence of giant planets (Jupiter and Saturn) are discussed. Based on the hypothesis of parametric resonance in the variation of global temperature with disturbances in the photosphere shape and the Earth-to-Sundistance due to the oppositions of said planets, a regression model that explains the observed long-term evolution of global temperature is built. It was shown that residuals of the model are close to white noise, i.e. the hypothesis almost entirely explains the effect of temperature increase for the period presented in the vernacular crutem3 database.

中压真空开关领域的最新研究成果

本文从实际应用的角度出发，系统地论述了目前真空开关技术领域里的最新研究成果，包括对真空开关的两个主要部分的研究：1、操动机构部分（为开关操作提供动能的部分，称为操动机构，AM）。2、开断部分（真空灭弧室，VI）。对真空开关进行整体设计时，还必须考虑以上两个部分的相互依赖性。对于操动机构的研究，源于单稳态永磁操动机构（MMA）概念的应用。采用单稳态永磁操动机构的断路器，能将机构的零件数降至最少，从而最大限度地消除影响真空断路器可靠性的主要原因。对于真空灭弧室部分，主要研究集中在两个关键部位，一是触头系统，二是真空密封。触头系统中纵磁场的应用加上特殊触头材料的使用，显著地提高了灭弧室的开断性能使用寿命。但真空灭弧室的使用寿命还与它的波纹管性能密切相关，传统的密封波纹管采用锻压工艺制造，而采用特殊焊接工艺能改善波纹管的受力结构，焊接波纹管可实现非常可观的操作次数，显著延长灭弧室的使用寿命。操动机构和真空灭弧室这两个主要部件的研究成果，为研制新一代小型化、轻便型的真空断路器产品提供了必要的条件，进一步拓展了真空断路器的应用领域，成为中压开关技术领域发展方向的代表。

近年来，在中压开关领域里，永磁操动机构真空断路器以其特有的小型化、高可靠性、免维护和长寿命正在成为电器制造企业和运行部门的热点。从结构上和起源上看，现有的永磁机构断路器可以分为两大类，即来自英国的双线圈双稳态永磁机构断路器和来自前苏联军事试验室的单线圈单稳态永磁机构断路器。前几年进入中国市场的永磁操动机构断路器，基本上都是双线圈双稳态结构，相对于单线圈单稳态结构来说，其设计只是用电磁机构代替了弹簧机构，尚未克服传统断路器机械零件过多的缺点，都具有体积较大、所需操作功率较大的特点。单线圈单稳态永磁机构断路器，即我们今天所知道的ISM，它在结构上取得了突破性改进，体积更小、所需操作功率也小，因而更加能够体现永磁机构真空断路器高可靠性、免维护和长寿命的优点。特瑞德电气集团创立于1990年，它的前身就是上面提到的前苏联军事科学试验室，创建时它的所有雇员均来自这个试验室，它继承了该试验室在军事领域里的多年研发经验和最高端成果。本文译自2005年10月发表在第五届输配电技术国际会议上的最新文献，Most Relevant Results from Research and Development in the Field of Medium Voltage Vacuum Circuit Breakers孝AReview。这篇论文的原作者Alexey Chaly，Viktor Poluyanov，vladimir zakharov，Helmut Rebstock等都是特瑞德电气集团的技术专家，其中，Alexey Chaly先生现任特瑞德电气集团总裁和技术总监，他在世界真空技术领域久负盎名，是国际科学委员会（PISC）真空放电及绝缘学会（ISDEIV）22名终身会员之一，拥有工程科学博士学位；Viktor Poluyanov先生现任特瑞德电气集团研究试验室主任，他的主要研究方向包括真空开断技术、真空接触技术和使用永磁操动机构的开关设备的设计方案；vladimir zakharov先生现任特瑞德电气集团控制模块研发部主任，Helmut Rebstock先生现任特瑞德电气集团北京代表处首席代表。
