摘　　要：某轻型卡车起动继电器内部增加了磁吹灭弧装置,利用永磁铁的磁力将电弧拉长、冷却,电弧被冷却而熄灭,保护触点不被电弧烧蚀。从根本上解决起动继电器触点易被电弧烧蚀问题,提高了起动继电器的可靠性。Some light truck is added with magnetic blowout device in starting relay. By use of magnetic force of permanent magnet, arc is elongated, cooled and extinguished, in this way the contact is protected from ablation. The problem of contact erosion of starting relay by arc is fundamentally solved, and the starting relay reliability is improved.
