DEVICE FOR TURNING INCANDESCENT LAMPS ON

摘要

electrical engineering. SUBSTANCE: device has electromagnetic relay, which is connected in parallel to incandescent lamp, and protection member, which is designed as inertial fuse with calibrated resistance. This results in possibility to decreased in-rush current by factor of 2.5-3 due to thermal non-linearity of incandescent lamp filament. EFFECT: increased service life. 3 dwg
