Low-voltage combined type marine electric device

Abstract

A low-voltage combined type marine electric device comprises a base. Three cabinets of identical structures are installed on the base and connected through fasteners. Each cabinet structurally comprises frames, each rectangular framework is formed by welding the two corresponding frames, two crossarms and two stand columns, side cross beams arranged at intervals are installed on the inner sides of the frames on the two sides, a vertical beam is installed on middle portions of the side cross beams of each cabinet and perpendicular to the side cross beams of each cabinet, and the two vertical beams of each cabinet are connected through a connecting beam; side closure plates are installed on the outer sides of the frames on the two sides, and each side closure plate is provided with installation holes; a front door plate is installed on each frame located at the front end, and each front door plate is provided with a front armrest and a front door locking device; a rear door plate is installed on each frame located at the rear end, and each rear door plate is provided with a rear armrest; a top cover plate is installed at the tops of the three cabinets through first bolts, and right-angle-shaped hoisting plates are installed on the top cover plate through fasteners in a spaced mode. The low-voltage combined type marine electric device is high in strength, attractive in appearance, high in protection level and universality and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to the technical field of ship electrical products, in particular to a low-voltage combined ship electric device used for ship power supply and distribution equipment. Background technique [0002] The marine low-voltage combined marine electrical device (hereinafter referred to as the marine electrical device) plays an extremely important role on the ship. It provides the continuity of the power supply operation of the marine electrical device during the ship's navigation. The reliability will directly affect the technical and economic indicators of the ship. Safe navigation to the ship. The structure of the ship's electrical device directly determines the reliability of the electrical equipment in use. In addition, when encountering the impact of strong winds and waves during navigation, the ship's electrical device will be subject to great shock and vibration. Components produce shock and vibration, which directly affects the...

AI Technical Summary

Problems solved by technology

When the ambient temperature is high, it will cause insufficient output of the generator and accelerated aging of the insulation

High relative humidity will make the insulation of electrical equipment damp, swell, delaminate and deform, etc., which will reduce the insulation performance, and will accelerate the corrosion of metal parts and peel off the coating

The existence of salt spray, the growth of mold, and the adhesion of oil mist and dust can all reduce the insulation of electrical equipment and affect the working performance

When the ship is subjected to severe shock and vibration, it will also cause electrical equipment damage, poor contact or malfunction
