四、医用供电的特殊要求及发电机组的选择(一)调压率及调频率医用电子仪器及医疗设备对工作电压比较敏感。电压偏低时,医用电子仪器工作失常,无影灯照度下降,电动吸引器无力,X 线机穿透能力下降;电压偏高时电气元件及无影灯泡寿命下降。频率降低会使电机转速下降,同时使电机、电器,X 线机变压器等励磁电流大幅
Fourth, the special requirements of medical power supply and the choice of generating units (A) the rate of pressure regulation and frequency modulation Medical electronic equipment and medical equipment is more sensitive to the operating voltage. When the voltage is low, medical electronic equipment malfunction, shadowless lamp illumination, power suction weakness, X-ray machine penetration decreased; high voltage electrical components and shadowless lamp life expectancy decline. Lower frequency will make the motor speed down, while the motor, electrical, X-ray machine transformer excitation current large
