摘　　要：大型臭氧发生器是由一台大功率电源经升压变压器向多个并联而成的放电单元供电,研究发现每个放电单元正常工作时的电流很小,若发生过载、短路等故障未及时切除,不仅影响放电单元的工作状态,也会对变压器和电源造成一定的损坏。为了更好地保护器件,对应用在放电单元一侧的熔断器给出了设计方法,并对熔断器在直流及高频交流条件下的温度-时间特性做了实验,发现高频条件下集肤效应会影响熔断器熔体的温升。Large ozone generator is a powerful power supply by the step-up transformer to multiple parallel unit power supply and discharge,the study found that each discharge unit work properly when the current is small,in case of overload,short circuit fault,failed to timely removal not only affects the working condition of discharge unit,will cause certain damage to transformer and power supply.In order to better protect the device,the design method of the fuse applied to one side of the discharge unit is given,and the temperature-time characteristics of the fuse under dc and high-frequency ac conditions are tested.
