Air-cooled and water-cooled transformer for ship

Abstract

The invention discloses an air-cooled and water-cooled transformer for a ship. The transformer comprises an air-cooling and water-cooling device, a control box, a transformer body and a frame box, wherein the transformer body is assembled in the frame box, a horizontal separation plate is arranged in the center inside the frame box to divide the frame box into an upper separation layer and a lower separation layer, the air-cooling and water-cooling device is arranged outside the frame box and comprises a fan and a water pipe, the control box is arranged beside the air-cooling and water-cooling device and controls on and off of the fan, and a plurality of stuffing boxes are arranged on both the frame box and the control box. The transformer has the advantages that by the aid of the air-cooling and water-cooling device, the temperature rise of the transformer is effectively reduced, and heat produced by the transformer is taken away through water circulation, so that the transformer is cooled, the effect is good, the limitation of a transformer winding to coil specifications can be reduced, and requirements of some special environments with ventilation limitations are met.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer using wind and water cooling. Background technique [0002] The basic working principle of the transformer is to perform electromagnetic conversion. In the process of operation, energy loss will inevitably occur, mainly the "iron loss" and "copper loss" of the iron core and copper wire. The loss of energy is mainly reflected in the heat dissipation of the iron core and copper wire, which is also the main reason for the heat generation of the transformer. [0003] At present, the cooling form of marine transformers is mainly dry-type self-cooling type. For large-capacity transformers, if the dry-type self-cooling type is used for cooling, the requirements for volume and weight are relatively large, and the temperature rise is high, and a large amount of heat is dissipated to the ambient air. , resulting in high requirements for cabin ventilation. However, the working environment of...

Problems solved by technology

However, the working environment of marine transformers is relatively narrow, which cannot provide a well-ventilated environment, and a large amount of heat cannot be dissipated in time, resulting in overheating of the transformer and affecting its normal operation and use.
