The utility model relates to a portable emergency opening and closing control device characterized by comprising a switching power supply. The input end of the switching power supply is connected with commercial power and the output end of the switching power supply is connected with the input end of a storage battery. The output end of the storage battery is connected with the input end of an isolation converter. The output end of the isolation converter successively and respectively outputs +12V, -12V, +12V, -1V, +24V, and -24V to a first output end, a second output end, a third output end, a fourth output end, a fifth output end, and a sixth output end. The portable emergency opening and closing control device also comprises a switch connected in series between the storage battery and the isolation converter. Probation proves that the portable emergency opening and closing control device may greatly improve the reliable closing rate of an intelligent vacuum circuit breaker, resolve a problem of unreliable closing of a conventional intelligent fast breaker, provide guarantee for timely power delivery recovery, and correspondingly improve power supply reliability.
