Explosion-proofing combined capacitor

The invention provides an explosion-proofing combined capacitor including a metal casing, a positioning sleeve, a core assembly, and a metal cover assembly, the metal casing is in a cylinder structure having an opened upper end, the core assembly is fixed in the metal casing through the positioning sleeve, the core assembly and the metal casing are insulated, the metal cover assembly is fixedly arranged at the opening end of the metal casing and the metal casing forms a sealing cavity, the metal casing is filled with an impregnating agent, two lead-out wires arranged on the core assembly pass through the metal cover assembly and then extend out of the metal casing, and the core assembly includes a capacitance element and an inductor that are serially connected with each other. The explosion-proofing combined capacitor is simple and compact in structure and small in size, stable in inductance parameter, less in loss, high in insulation resistance, good in self-healing capability, stable in performance, high in impact resistance current, high in overloading capability, fireproofing and explosion-proofing, high in safety, long in service life, and suitable for washing machines, air conditioners, refrigerators or other electric appliances.
