Description

Technical Field

[0001] This utility model relates to the field of transformer maintenance technology, and in particular to a dry-type transformer with a moisture-proof device. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. A dry-type transformer is mainly composed of a core made of silicon steel sheets and a coil cast with epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation.

[0003] However, existing technologies still have shortcomings. Existing dry-type transformers mainly rely on passive dehumidification by desiccants, which has poor dehumidification effect, low efficiency, and difficulty in providing comprehensive moisture protection for dry-type transformers.

[0004] Therefore, we propose a dry-type transformer with a moisture-proof device to solve this problem. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide a dry-type transformer with a moisture-proof device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A drying plate is connected; a second mounting frame is slidably installed on the inner surface of the mounting groove; a filter screen is fixedly connected to the inner surface of the second mounting frame; a guide rod is slidably installed on the inner surface of the guide groove; a fixing plate is fixedly connected to one end of the guide rod; a threaded rod is rotatably installed on the inner surface of the fixing plate; a rotating block is fixedly connected to one end of the threaded rod; a second mounting shell is fixedly connected to the other end of the air inlet; a vent pipe is fixedly connected to one end of the second mounting shell; a nozzle is fixedly connected to the outer surface of the vent pipe; a third mounting shell is fixedly connected to one end of the air outlet; a connecting pipe is fixedly connected to one end of the third mounting shell; and an exhaust fan is fixedly connected to the other outer surface of the transformer body.

[0008] Preferably, the threaded rod is rotatably mounted on the inner surface of the threaded groove; the first mounting frame is fixed to the inner surface of the mounting groove by a fixing plate.

[0009] Preferably, one end of the vent pipe is fixedly connected to the inner surface of the transformer body; one end of the connecting pipe is fixedly connected to the input of the non-exhaust fan.

[0010] Preferably, the drying plate is located on one side of the air inlet; the filter screen is located on one side of the drying plate.

[0011] Preferably, the rotating block is rotatably mounted on one side of the outer surface of the fixed plate.

The structure includes a base, transformer body, air inlet, air outlet, first mounting shell, slide groove, first mounting frame, drying plate, handle, second mounting shell, vent pipe, nozzle, third mounting shell, exhaust fan, connecting pipe, guide rod, fixing plate, threaded rod, and rotating block. When the exhaust fan is activated, it draws air from the transformer body through the connecting pipe. Outside air is drawn into the transformer body, where dust is filtered by a filter, and moisture is absorbed. The filtered air then flows into the vent pipe and is sprayed out through the nozzle, thus replacing the air inside the transformer body and keeping the interior dry. This provides a moisture-proof function for the transformer body.

[0013] In this utility model, a dry-type transformer with a moisture-proof device is provided. Through the arrangement of a slide groove, a first mounting frame, a drying plate, a handle, a mounting groove, a guide groove, a threaded groove, a second mounting frame, and a filter screen, when replacing the drying plate, the first mounting frame can be removed from the slide groove by using the handle, and the drying plate can be replaced. When cleaning the filter screen, rotating the rotating block will drive the threaded rod to rotate, and the rotation of the threaded rod will drive the fixed plate away from the second mounting frame, so that the second mounting frame can be removed from the mounting groove, and the filter screen can be cleaned. This realizes the rapid replacement and cleaning of the drying plate and the filter screen, improving efficiency.

A second mounting frame 13 is slidably installed on the inner surface of the groove 10; a filter screen 14 is fixedly connected to the inner surface of the second mounting frame 13; a guide rod 21 is slidably installed on the inner surface of the guide groove 11; a fixing plate 22 is fixedly connected to one end of the guide rod 21; a threaded rod 23 is rotatably installed on the inner surface of the fixing plate 22; a rotating block 24 is fixedly connected to one end of the threaded rod 23; a second mounting shell 15 is fixedly connected to the other end of the air inlet 3; a vent pipe 16 is fixedly connected to one end of the second mounting shell 15; a nozzle 17 is fixedly connected to the outer surface of the vent pipe 16; a third mounting shell 18 is fixedly connected to one end of the air outlet 4; a connecting pipe 20 is fixedly connected to one end of the third mounting shell 18; and an exhaust fan 19 is fixedly connected to the outer surface of the other side of the transformer body 2.

[0022] Furthermore, the threaded rod 23 is rotatably mounted on the inner surface of the threaded groove 12; the first mounting frame 7 is fixed to the inner surface of the mounting groove 10 by the fixing plate 22.

[0023] Furthermore, one end of the vent pipe 16 is fixed to the inner surface of the transformer body 2; one end of the connecting pipe 20 is fixed to the input end of the non-exhaust fan 19.

This enables quick replacement and cleaning of the drying plate 8 and the filter screen 14, improving efficiency.
