分类:断电延时、通电延时、带瞬动触点延时三种。 结构认识:空气阻尼式时间继电器 组成认识:电磁系统、延时机构、工作触点 动作原理分析:空气阻尼式时间继电器(通电延时型) 当线圈1通电后,衔铁3吸合,微动开关16受压其触点动作无延时,活塞杆6在塔形弹簧8的作用下,带动活塞12及橡皮膜10向上移动,但由于橡皮膜下方气室的空气稀薄,形成负压,因此活塞杆6只能缓慢地向上移动,其移动的速度视进气孔的大小而定,可通过调节螺杆13进行调整。经过一定的延时后,活塞杆才能移动到最上端。这时通过杠杆7压动微动开关15,使其常闭触头断开,常开触头闭合,起到通电延时作用。
Categories: power off delay, power delay, with instantaneous contact delay three kinds. The structure of understanding: the air damping type time relay: analysis of electromagnetic system, delay mechanism, working principle of contact action: air damping type time relay (cm-pss type 1) when the coil is energized, the armature 3 pull the switch 16 compression the contact action without delay, a piston rod 6 in tower spring 8 under the drive piston 12 and the rubber membrane 10 moves upward, but due to the thin rubber membrane, below the gas chamber in the air to form the negative pressure, the piston rod 6 is only slowly moving upward, the moving speed as the air inlet depends on the size, can be adjusted through the adjusting screw 13. After a certain delay, the piston rod can move to the top. At this time, the lever 7 is pressed to move the microswitch 15, so that the normally closed contact is disconnected, and the normally opened contact is closed, so as to play the role of energizing delay.
