平衡力继电器吸合二步与释放二步产生机理及寿命影响分析
Analysis of the Mechanism and Impact on Service Life of the Two-Step Engagement and Two-Step Release Processes in Balance Force Relays
摘要
Abstract
Balance force relays have extensive applications,yet manufacturers frequently encounter phenomena such as'two-step engagement'and'two-step release'during product commissioning.Such occurrences may reduce the electrical lifespan of the relays.The mechanisms underlying'two-step engagement'and'two-step release'are investigated,and their impact on product longevity is analyzed.The operating principle of balance force relays and the ideal matching relationship between attraction and repulsion forces are first elucidated from a magnetic circuit perspective.It then analyses the mechanisms behind'two-step engagement'and'two-step release'occurring during specific phases,along with their impact on product lifespan.Finally,selected samples undergo lifespan testing,confirming that'two-step engagement'during static overtravel and'two-step release'during dynamic overtravel reduce product lifespan,consistent with analytical findings.关键词
