Problems solved by technology
[0004] However, there are still defects in the existing automatic frequency conversion cabinets. For example, the existing frequency conversion cabinets generally use a single sealing strip on one side of the cabinet door or on the cabinet body to achieve the sealing of the frequency conversion cabinet. The sealing performance is poor, which makes it easy for dust to enter Go to the frequency conversion cabinet to corrode the components

The invention discloses a combined type high-sealing-performance automatic frequency conversion cabinet. The frequency conversion cabinet comprises a frequency conversion cabinet body, wherein the frequency conversion cabinet body is hinged to a cabinet door through hidden hinges; a first sealing strip is adhered to the surface of one side, close to the cabinet door, of the frequency conversion cabinet body; a magnetic lock is fixed on the inner wall of one end, close to the cabinet door, of the frequency conversion cabinet body; two electromagnets are embedded into the magnetic attraction lock; an enameled coil is arranged on the outer circumferential face of each electromagnet in a surrounding mode; a first protruding plate is arranged on the surface of the side, close to the frequency conversion cabinet body, of the cabinet door; a second protruding plate is arranged on the surface of the side, away from the cabinet door, of the first protruding plate; a second sealing ring is arranged on the outer circumferential face of the second protruding plate in a surrounding mode; and a magnetic attraction plate is embedded in the cabinet door. Through cooperation of the cabinet door andthe frequency conversion cabinet body, good sealing performance is provided between the cabinet body and the cabinet door of the frequency conversion cabinet, so dust is prevented from entering the frequency conversion cabinet to corrode electrical apparatus elements in the frequency conversion cabinet.
Description
technical field [0001] The invention relates to the technical field of frequency conversion cabinets, in particular to a combined high-seal automatic frequency conversion cabinet. Background technique [0002] The frequency conversion cabinet applies the frequency converter to drive the control cabinet of the power unit.
