The invention relates to the field of high-voltage electrical equipment, in particular to an inflatable type high-voltage switch air box. The inflatable type high-voltage switch air box comprises a switch air chamber and a bus air chamber; a disconnecting switch is arranged in the upper part of the switch air chamber, the disconnecting switch is connected with a disconnector wire inlet terminal ofthe middle of the switch air chamber through a moving cutter seat copper row, and a disconnector tail wire outlet terminal is connected with a wire outlet sleeve of the lower part of the switch air chamber through a wire outlet copper guide wire; a disconnecting switch moving cutter driving rotary shaft is connected with a pull rod of a disconnecting switch operating mechanism of the exterior ofthe switch air chamber; and a disconnector moving terminal pull rod is connected with a disconnector operating mechanism of the exterior of the switch air chamber. The switch air chamber and the bus air chamber are integrally welded through a laser, are mutually sealed to form independent air chambers, and are separately provided with pressure relief openings. The inflatable type high-voltage switch air box reduces the volume of a switch, a double air chamber structure is adopted, the integral strength of the air box is improved, meanwhile, a bus is separated from the switch air chamber, and the safety of switch equipment is improved.
