Safety control system and method for hydrogen production power supply

The invention discloses a safety control system of a hydrogen production power supply, which comprises two or more heat dissipation systems running in parallel, the heat dissipation systems are controlled by a control unit, the input end of the control unit is connected with a temperature sensor, and the temperature sensor is used for collecting temperature data of the hydrogen production power supply; and the control unit controls the heat dissipation system to work according to the temperature data. The device has the advantages that the hydrogen production power supply is cooled in two modes, so that the temperature abnormity can be effectively reduced; and meanwhile, through the design of control strategies of the two cooling systems, temperature safety can be effectively guaranteed, and the probability of temperature abnormity is reduced. 本发明公开了制氢电源的安全控制系统，包括并行运行的两个或以上散热系统，所述散热系统受控于控制单元，所述控制单元的输入端与温度传感器连接，所述温度传感器用于采集制氢电源的温度数据；所述控制单元根据温度数据来控制散热系统的工作。本发明的优点在于：对制氢电源的冷却采用两种方式进行冷却，可以有效减少温度的异常；同时通过两种冷却系统的控制策略的
