DLS(电磁联锁)是东风型内燃机车柴油机运转必不可少的器件,它是螺管式电磁机构。当DLS线圈得电,其动铁心吸合,调速器才能工作,柴油机方能运转。当DLS线圈失电时,柴油机就停机。机车运行中,特别是在大坡道上牵引时,柴油机停转就意味着“机破”。 DLS线圈在运用中经常发生烧损,造成停车事故,甚至会引起机车火灾。DLS线圈之所 DLS (Electromagnetic Interlock) is an indispensable component for the operation of diesel engine of Dongfeng diesel locomotive. It is a solenoid electromagnetic mechanism. When the DLS coil is energized, its moving core pull, governor to work, diesel engine can run. When the DLS coil is out of power, the diesel engine is stopped. Locomotive running, especially when pulling on a large ramp, the diesel engine stall means “machine broken.” DLS coil in the use of frequent burning, resulting in parking accidents, and even lead to locomotive fire. DLS coil place
