    • A fan system is electrically connected to a power supply and receives a power generated from the power supply. The fan system includes at least one fan, a driving circuit, at least one protecting device, and a protecting circuit. The driving circuit is electrically connected to the fan and receives the power to drive the fan. The protecting device is electrically connected with the fan, and the protecting circuit is electrically connected between the protecting device and the driving circuit. When one fan is short-circuited, the protecting circuit outputs a current value larger than a current-limited value of the protecting device. Also, a method for protecting a fan system is disclosed.
    • 风扇系统电连接到电源并且接收从电源产生的电力。 风扇系统包括至少一个风扇,驱动电路,至少一个保护装置和保护电路。 驱动电路电连接到风扇并接收电力以驱动风扇。 保护装置与风扇电连接,并且保护电路电连接在保护装置和驱动电路之间。 当一个风扇短路时,保护电路输出大于保护装置的限流值的电流值。 另外,公开了一种保护风扇系统的方法。
