Temperature-control heat-dissipation protection device for non-partial-discharge variable-frequency power supply

The utility model relates to a temperature control heat radiation protection device used for a non-partial discharge variable frequency power supply, comprising a housing, the inner bottom end of the housing is fixedly connected with a separator plate, the separator plate is net-shaped, the middle part of the bottom end of the housing is provided with a rectangular opening, and the housing is fixedly connected with a semiconductor chilling plate at the rectangular opening. A plurality of circular openings are formed in the positions, at the bottom end of the partition plate, of the outer side of the shell, direct-current fans are fixedly connected to the positions, at the circular openings, of the shell, and a temperature sensor and a single-chip microcomputer are arranged in the shell and electrically connected with the semiconductor chilling plate and the direct-current fans respectively. In the process that the power supply is placed in the shell for use, the temperature sensor can be used for monitoring h
