摘要
针对JB/T 10923—2020中两项技术指标要求:不小于5.5 mm的电气间隙和短路电流承载能力,提出一种采用双稳态磁保持电磁铁作为驱动器的磁保持继电器。首先对电气间隙、短路电流承载的类比设计等进行阐述,其次对降低电磁铁功耗进行设计、仿真分析。最后,得出电磁铁能够提供足够的电气间隙和高短路电流承载能力所需的行程和力,同时提供了一套工程设计思路及方法,为电磁铁的低功耗优化设计提供参考。
Aiming at two technical requirements in JB/T 10923—2020:electrical clearances through air no less than 5.5 mm and short-circuit current carrying capacity,a kind of relay using bistable magnetic latching electromagnet as the driver is proposed.Firstly,the analog design of electrical gap and short-circuit current carrying is described.Secondly the design and simulation analysis reducing the power consumption of electromagnet are carried out.Finally,it is concluded that the electromagnet can provide the requirements of large electrical clearance through air and the travel and force required for the high short-circuit current carrying capacity.Simultaneously it provids a set of engineering design ideas and methods,providing a reference for the lowpower optimization design of the electromagnet.
