摘要:

针对额定负载380 V AC/25 A的大功率电磁继电器,依据GJB 1461B—2024《大功率电磁继电器通用规范》,系统阐述了其结构设计、参数计算与多物理场仿真验证方法。设计采用“平衡力”式电磁驱动系统、4路主触点并联布局及“空间扩增+多腔隔弧罩+充氮”复合灭弧方案,结合激光密封充氮工艺,提升了产品的动作可靠性、电弧抑制能力和环境适应性。通过电磁场、结构力学及热场的多物理场耦合仿真,验证了吸反力匹配、抗冲击振动性能及稳态温升均满足指标要求,形成了一套完整的设计—仿真—验证闭环流程,为同类高可靠性继电器的研制提供了参考。

Abstract:

A high-power electromagnetic relay with rated parameters of 380 V AC/25 A is researched. In accordance with GJB 1461B—2024, its structural design, parameter calculation and multi-physics simulation verification method are systematically elaborated. This design adopts a “balanced-force” electromagnetic drive system, four-channel main-contact parallel layout, and a composite arc-quenching scheme of “spatial expansion + multi chamber arc extinguishing cover + nitrogen filling”. Combined with laser-sealing and nitrogen-filling processes, the product’s operational reliability, arc-suppression capability and environmental adaptability are improved. Through coupled multi-physics simulations of electromagnetic field, structural mechanics and thermal field, the matching of electromagnetic attraction-reaction forces, shock-vibration resistance and steady-state temperature rise are verified to satisfy index requirements. A complete closed-loop workflow of design-simulation-validation is established, which provides a reference for the development of similar high-reliability relays.

Key words: high-power electromagnetic relay, balanced-force, composite arc quenching, multi-physics simulation
