Sealed water-cooled dry-type transformer

Abstract

The invention discloses a sealed water-cooled dry-type transformer which comprises a storage box shell, a drawing box, a U-shaped supporting plate, a control box and a fire extinguishing assembly. A bottom plate is fixed to the lower side of the interior of the storage box shell, a sliding assembly is slidably connected to the bottom plate, and the U-shaped supporting plate is in threaded connection with a second supporting plate through a bolt; the second supporting plate is located on the lower sides of a dry-type transformer body, water cooling assemblies and an energy-saving assembly, the lower side of a spring shaft is in threaded connection to the upper side of the second supporting plate, the dry-type transformer body is located between the water cooling assemblies, and a fire extinguishing assembly, a smoke sensor and an auxiliary illuminating lamp are all fixed to the upper side of the interior of the storage box shell. According to the sealed water-cooled dry-type transformer, the whole dry-type transformer body can be moved and finally moved out of the storage box shell, the water cooling effect of the dry-type transformer body can be guaranteed, the energy-saving effect can be achieved, and automatic fire extinguishing can be achieved when spontaneous combustion of the dry-type transformer body occurs.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a sealed water-cooled dry-type transformer. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil, and dry-type transformers are small in size and heavy in weight. Lightweight, takes up less space, and has the advantages of low installation costs. [0003] The existing dry-type transformer is placed in a small space, the heat dissipation effect is poor, which affects the service life of the dry-type transformer, and when the existing dry-type transformer needs maintenance, it is necessary to disassemble the entire dry-type transformer before proceeding. It is inconvenient to maintain and use. At the same time, when the dry-type transfor...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sealed water-cooled dry-type transformer to solve the problem that the existing dry-type transformer proposed in the above background technology is placed in a small space, and the heat dissipation effect is poor, which affects the service life of the dry-type transformer. Moreover, when the existing dry-type transformer needs maintenance, it is necessary to disassemble and take out the entire dry-type transformer before repairing, which is inconvenient to use. At the same time, when the dry-type transformer spontaneously ignites, it cannot be processed quickly, which affects the safety of life and property.
