Marine frequency conversion cabinet with high stability

Abstract

The invention discloses a marine frequency conversion cabinet with high stability. The marine frequency conversion cabinet comprises an outer box body, a sliding rail, an inner box body, a sliding strip, a buffer unit, a hollow heat conduction partition plate and a circulation unit; the appearance of the outer box body is in a cuboid shape. The front side of the outer box body is arranged to be inan opening shape, and two sides of the middle position of the upper surface of the lower plate of the outer box body and the middle position of the upper plate are each fixedly connected with a sliding rail. The inner box body is in a box shape with an opening in the front side. A sliding strip is fixedly connected to each of the upper surface, corresponding to the sliding rail, of the inner boxbody and the lower surface of the lower plate; the sliding strips are connected with the corresponding sliding rails in a sliding manner; the inner wall of the inner box body is fixedly connected withthe hollow heat conduction partition plate at equal intervals. According to the invention, the frequency conversion cabinet has the advantages that the cabinet is good in damping effect, high in heatdissipation efficiency and good in moisture resistance, can be applicable to high-shaking places such as ships, meets heat dissipation requirements of high-power frequency converters and is not easyto damage, and heat dissipation requirements of the high-power frequency converters can be met.

Description

technical field [0001] The invention relates to the technical field of frequency conversion cabinets, in particular to a highly stable marine frequency conversion cabinet. Background technique [0002] The frequency conversion cabinet refers to the control cabinet that uses the frequency converter to drive the power device. Because of its good starting performance, speed regulation performance and energy-saving effect, it has become the currently popularized power drag method. A variety of electrical accessories are usually installed in the frequency conversion cabinet, so the requirements for circuit safety are relatively high, especially if the frequency conversion cabinet is in a relatively humid environment for a long time, it will not only corrode the electrical components, but also easily cause circuit short circuit or other accidents. The moisture-proof effect of the inverter cabinet is often not good. A vertical frequency conversion cabinet proposed according to ap...

Problems solved by technology

A variety of electrical accessories are usually installed in the frequency conversion cabinet, so the requirements for circuit safety are relatively high, especially if the frequency conversion cabinet is in a relatively humid environment for a long time, it will not only corrode the electrical components, but also easily cause circuit short circuit or other accidents. The moisture-proof effect of the inverter cabinet is often not good

A vertical frequency conversion cabinet proposed according to application number 201710430119.6, including a controller, a cooling fan, a power supply, a power transmission box, a horizontal partition and a vertical partition, the left and right ends of the horizontal partition and the top of the front panel and the rear panel The two ends of the vertical partition are vertically connected with the horizontal partition and the bottom plate; the front of the horizontal partition is provided with the first, second and third frequency conversion groups from top to bottom, and the back is sequentially provided with the first Radiators 1, 2, and 3, the controller on the right side of the vertical partition near the third radiator includes a metal case, left power cord, right power cord, left conductive sheet, right conductive sheet, and left conductive folding strip , the right conductive folding strip, the left wax strip, the right wax strip and the middle conductive part. The vertical frequency conversion cabinet has poor shock absorption effect and cannot be used in high shaking places such as ships. The heat dissipation efficiency is low and it is not suitable for high-power frequency converters. Heat dissipation requirements, easy to damage, poor moisture resistance
