The invention discloses an explosion-proof frequency conversion all-in-one machine which comprises a motor, a frequency converter, a filtering assembly, a cable connector, a shell and a cooling system. The motor, the frequency converter, the filtering assembly and the cooling system are all arranged in the shell; the motor is connected with the frequency converter, the frequency converter is connected with the filtering assembly, and the cable connector is arranged on the shell. According to the explosion-proof frequency conversion all-in-one machine, the frequency converter is combined and shares the same cooling system with the motor; meanwhile, the filtering assembly is combined with the frequency converter and the motor, so as to allow the electromagnetic compatibility of the frequency converter to meet requirements of a standard, improve the anti-jamming capability of the frequency converter, reduce interference to the outside world, and improve work efficiency of the explosion-proof frequency conversion all-in-one machine. Meanwhile, a cable is brought to by means of the quick cable connector, so that the integration level of equipment is promoted, the equipment can be conveniently used on site, and application is simplified.
