Development of Multi-functional Electronic Power Assisting Device of Substation Equipment

摘要

The direct-current motor has been widely used in the modern electronic products, such as automatic control system, electronic equipment, home appliances, and electronic toys. The tape recorder, record player, recorder, and computer cannot work without the direct-current motor. So the control of the direct-current motor is a very practical technology. The direct-current motor has good starting performance and speed regulation characteristics, which is characterized by the big starting torque, big maximum torque, the smooth and economical speed regulation in a wide range, easy rotational speed regulation and high efficiency after speed regulation. Compared with AC speed regulation, the direct-current motor is complex in structure, with high production cost and heavy maintenance work. The direct-current regulator is widely applied in CNC machine tools, paper printing, textile printing and dyeing, fiber optic cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, biological equipment, printed circuit board equipment, experimental equipment, welding and cutting, light industry machinery, logistics and transportation equipment, medical equipment, communication equipment, radar equipment, satellite ground receiving system and other industries. This paper aims at a hand-held speed regulation device, which can make the manual drive of substation maintenance to electric drive, so as to save energy and time.
