Special harmonic filter for rail transit

Abstract

The invention discloses a special harmonic filter for rail transit. The special harmonic filter for rail transit comprises a shell, rectangular grooves are formed in the side walls of the two ends ofthe shell, the rectangular grooves are through grooves, and is internally movably provided with mounting plates, each movably plate is internally provided with two mounting cavities, the inner walls of the two ends of the mounting cavity are fixedly connected with elastic pieces, the free ends of the elastic pieces are fixedly connected with sliding plates, positioning inserting plates are fixedlyarranged at one surfaces, back to the elastic pieces, of the sliding plates, penetrate the mounting cavities and are movably inserted with positioning slots arranged in the rectangular grooves, afterthe movable plates at the two sides of the shell are completely dismounted, and elements in the shell are maintained, so that the shell can be maximumlly dismounted, a top cover can be avoided to bedismounted to cause inconvenience of maintenance, the maintenance area is expanded, the maintenance is more thorough, subsequent installation is convenient, operation is easy and rapid, and starting is easy.

Description

technical field [0001] The invention relates to the technical field of harmonic filters, in particular to a special harmonic filter for rail transit. Background technique [0002] With the continuous vigorous development of the domestic rail transit industry, various equipment and technologies are constantly being updated. After it was put into use, a series of problems began to emerge. A harmonic filter needs to be installed on the DC bus of the inverter inside the vehicle-mounted inverter air conditioner, which is a device for filtering out one or more harmonics in the power system. The harmonic filter is in progress During maintenance, the existing top cover of the housing can only be removed for maintenance of internal components. This maintenance method of only removing the top cover has a small range of maintenance and is limited, and cannot perform large-scale and all-round inspection of internal components. For maintenance, we propose a special harmonic filter for r...
