The invention relates to a method for preventing a high-voltage switch cabinet from being burnt, and mainly solves the problem that in the prior art, the safety of the high-voltage switch cabinet is relatively poor due to the fact that the high-voltage switch cabinet is easily burnt. The method and a device for preventing the high-voltage switch cabinet from being burnt are adopted to prevent thehigh-voltage switch cabinet from being burnt. The device comprises a cabinet internal temperature and humidity monitoring unit, a bus temperature monitoring unit, a bus current monitoring unit, a circuit breaker contact temperature monitoring unit, a data storage unit, a data processing unit, an alarm unit and an execution unit; the cabinet internal temperature and humidity monitoring unit, the bus temperature monitoring unit, the bus current monitoring unit and the circuit breaker contact temperature monitoring unit are connected with the data storage unit through data lines; the data storageunit is connected with the data processing unit through a data line; and the data processing unit is connected with the alarm unit and the execution unit through data lines. According to the technical scheme, the problem is better solved; and the method and the device can be applied to the safe operation of the high-voltage switch cabinet.
