一种新型矿用真空永磁控制器设计

摘要

Aiming at the control need of various mining permanent magnetic vacuum circuit breakers, this stud- y realizes the new intelligent mining vacuum permanent magnet controller based on CPLD. The full electronic circuit non-contact integrated software design is adopted. The switching power with wide-range input and constant-voltage and constant-current output is adopted as the power. The voltage and current are continuously adjustable and there- fore reliable. The electronic switch comprised mainly of a transistor and an IGBT is used to control the break-brake power so that the output energy can be controlled and adjusted, and the safety of the mine and the reliability of the breaker can be ensured.%针对各种矿用永磁机构真空断路器的控制需求，实现了基于CPLD的新型智能矿用真空永磁控制器。采用全电子电路无触点软件一体化设计，电源采用宽范围输入、恒压恒流输出的开关电源设计，电压和电流连续可调，具有较高的可靠性；用三极管和IGBT组成的电子开关通断来控制钞分闸的能量，使输出能量可控、可调，保证了矿井的安全和断路器可靠工作。
