Accompanying drawing explanation
Illustrate with embodiment below in conjunction with accompanying drawing.
Accompanying drawing is the controller for electromagnetic crane electrical principle diagram of block of superpower excitation lifting steel scrap.
In accompanying drawing: 1-rectifier transformer; 2-three-phase full-bridge controlled rectifier; 3-lifting electromagnet; 4-inhales blowing switch; The superpower excitation control circuit of 5-; 6-energizing signal driving circuit.
Detailed description of the invention
Embodiment, with reference to accompanying drawing, a controller for electromagnetic crane for superpower excitation lifting steel scrap, comprises rectifier transformer (1), three-phase full-bridge controlled rectifier (2), lifting electromagnet (3), inhales blowing switch (4), superpower excitation control circuit (5) and energizing signal driving circuit (6); It is characterized in that rectifier transformer (1) is connected with three-phase full-bridge controlled rectifier (2); Three-phase full-bridge controlled rectifier (2) is connected with lifting electromagnet (3), inhales blowing switch (4) and is connected with superpower excitation control circuit (5); Superpower excitation control circuit (5) is connected with energizing signal driving circuit (6); Energizing signal driving circuit (6) is connected with three-phase full-bridge controlled rectifier (2).
Principle of work: during suction, inhale blowing switch (4) and be placed in suction position, send suction order to superpower excitation control circuit (5), superpower excitation control circuit (5) first exports superpower excitation trigging pulse, start timer simultaneously, control three-phase full-bridge controlled rectifier (2) by energizing signal driving circuit (6) and export the superpower field voltage several seconds (general 5 ~ 8 seconds, the time is adjustable) to lifting electromagnet (3); After superpower excitation time arrives, superpower excitation control circuit (5) transfers to export magnet excitation trigging pulse, control three-phase full-bridge controlled rectifier (2) by energizing signal driving circuit (6) and export the magnet excitation voltage several seconds (general 3 ~ 5 seconds, the time is adjustable) to lifting electromagnet (3); After strong excitation time arrives, superpower excitation control circuit (5) transfers to export normal excitation trigging pulse, controls three-phase full-bridge controlled rectifier (2) export normal field voltage to lifting electromagnet (3) by energizing signal driving circuit (6); Complete lifting electromagnet from super strong to strong again to the overall process of normal excitation.Superpower field voltage is generally at 500 ~ 600VDC, and magnet excitation voltage is generally at 290 ~ 320VDC, and normal field voltage is 200V.Although the superpower excitation time only several seconds, the super-strong magnetic of short time can improve greatly grabs steel power, and then increases work efficiency.
