摘要

本文比较了冷焊和预打焊的特点，并将其作为电容性负载切换的典型电流。研究了几种不同工艺制备的CuCr触点材料。本文研究了在模拟电容性负载切换的“O”、“600A/500Hz制电流CO”和“3kA/500Hz制电流CO”模式下，模拟电容性负载切换的合成单相方案中，这些特性与所获得的NSDD概率之间的关系。阐明了焊接与不同材料介电特性之间的联系。描述了每种研究材料经过上述操作后的典型接触面。

Investigation of welding characteristics and NSDD probabilities of different contact materials under capacitive load conditions

This paper compares characteristics of cold welding and welding formed due to prestrike with making current typical for capacitive load switching. Several CuCr contact materials manufactured using different technologies are investigated. The correlation between these characteristics and NSDD probability obtained in a synthetic single-phase scheme, imitating capacitive load switching in “O”, “CO for 600A/500Hz making current” and “CO for 3kA/500Hz making current” modes is studied in this paper. The connection between welding and dielectrical characteristics of different materials is demonstrated. Typical contact surface after the abovementioned operations for each of the studied materials is described.
