Anti-explosion vehicle-mounted converter

The invention relates to the field of converters, and particularly relates to an anti-explosion vehicle-mounted converter. The anti-explosion vehicle-mounted converter aims at solving the problem that the pressure of an existing vehicle-mounted converter can not be rapidly relieved. The anti-explosion vehicle-mounted converter comprises a cabinet body, pressure relief openings are formed in the cabinet body, pressure relief membranes cover the pressure relief openings, and the pressure relief membranes are provided with weak links and are made of high polymer materials. The high polymer materials need to meet the conditions that the density is 0.93-0.98g/cm , the rigidity is 55-75HHD, the tensile strength is 14-34MPa, the breaking elongation is 180%-430%, the tensile strength after aging is 13-33MPa, and the breaking elongation after aging is 150%-400%. The anti-explosion vehicle-mounted converter has the advantages that the structure is simple, and when the anti-explosion vehicle-mounted converter normally works or faults are not serious, the IP protection level and aging corrosion requirements of the anti-explosion vehicle-mounted converter are guaranteed; meanwhile, the aim of rapid pressure relief is achieved, and the anti-explosion vehicle-mounted converter is convenient to maintain.
