The invention relates to the technical field of medium-frequency static transformation power supplies, and discloses a combined medium-frequency static transformation power supply convenient to disassemble and assemble, which comprises a power supply assembly, a shell and a bottom plate, wherein the power supply assembly is fixedly mounted on the upper surface of the bottom plate, the shell is of a hollow structure with an opening in the bottom, and strip-shaped slots are symmetrically formed in the edge of the opening; strip-shaped inserting plates matched with the strip-shaped inserting grooves are symmetrically and fixedly connected to the upper surface of the bottom plate, the strip-shaped inserting plates and the strip-shaped inserting grooves are arranged in a clamped mode, limiting mechanisms are installed between the strip-shaped inserting plates and the strip-shaped inserting grooves, and the bottom end of the shell abuts against the upper surface of the bottom plate. The limiting mechanism comprises a rectangular groove formed in the side wall of the strip-shaped inserting groove, a spring is fixedly connected to the groove bottom of the rectangular groove, and a rectangular clamping block in sliding connection with the rectangular groove is fixedly connected to the other end of the spring. According to the invention, the shell of the medium-frequency static variable power supply can be assembled and disassembled conveniently, so that the power supply assembly in the shell can be maintained conveniently as required.
Description
technical field [0001] The invention relates to the technical field of intermediate frequency static variable power supplies, in particular to a combined intermediate frequency static variable power supply that is easy to assemble and disassemble. Background technique [0002] The intermediate frequency static variable power supply is a 400Hz static variable frequency power supply specially designed and manufactured for aviation and military electronic and electrical equipment using high-frequency power electronic switching technology. In the case of intermediate frequency power supply, it is the replacement product of unit type variable frequency power supply. The voltage and frequency of this product have an adjustment range of ±20%, which is suitable for laboratories or production lines as a power supply for debugging experiments. [0003] In the prior art, the casing of the intermediate frequency static variable power supply is mostly assembled by bolts, and the screws ...
