Abstract：

Aiming　at　the　problem　of　arc　extinguishing　of　HVDC　relay,　this　paper　presents　an　optimal　design　of　electromagnetic　system　based　on　orthogonal　test.　In　order　to　improve　the　breaking　speed　of　the　contact,　a　three-dimensional　finite　element　model　of　the　relay　electromagnetic　system　is　established.　The　key　parameters　of　the　electromagnetic　system　performance　are　analyzed,　the　optimization　variables　are　determined,　and　the　simulation　model　is　verified　by　dynamic　characteristic　experiment.　On　this　basis,　the　orthogonal　test　method　is　used　to　optimize　the　electromagnetic　system　of　relay.　The　results　show　that　the　optimal　design　can　improve　the　breaking　speed　of　the　relay　contact　and　lay　a　theoretical　foundation　for　improving　the　life　of　the　relay.　©　Beijing　Paike　Culture　Commu.　Co.,　Ltd.　2025.
