Description

Technical Field

[0001] The present invention relates to the technical field of dry-type transformers, and particularly relates to an energy-saving and efficient 200 kVA dry-type transformer. Background Art

[0002] A transformer is a static electrical device used to exchange AC voltage and current and transmit AC electrical energy. Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, CNC machinery equipment, etc. Simply put, a dry-type transformer refers to a transformer in which the iron core and winding are not impregnated in insulating oil. Due to its efficient transmission performance, it is widely used in power plants, substations and other places; the use of transformers has the inherent characteristic of no-load loss. Considering the large number, wide application range and long operation time of transformers, this will directly cause problems such as unsatisfactory energy consumption and environmental protection of transformers; on the contrary, if the energy consumption of transformers can be reduced, it will be beneficial to the national call for energy conservation and emission reduction and make a significant contribution to environmental protection; therefore, there is an urgent need for an energy-saving and efficient 200 kVA dry-type transformer to improve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose an energy-saving and efficient 200 kVA dry-type transformer.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An energy-saving and efficient 200 kVA dry-type transformer, including a transformer body and a housing. The transformer body is arranged inside the housing. A first heat-conducting plate is fixedly installed inside the housing. The transformer body is installed on the upper end of the first heat-conducting plate. A vertically-shaped movable rod is fixedly connected to the lower end of the first heat-conducting plate. A sleeve is sleeved on the lower end of the movable rod. A spring is connected between the sleeve and the movable rod. A second heat-conducting plate is fixedly connected to the lower end of the sleeve. Uniformly distributed heat-conducting rods are fixedly installed at the lower end of the second heat-conducting plate. The lower ends of the heat-conducting rods extend to the outside of the housing. Support legs are arranged at the lower end of the housing. A water storage tank is also installed below the housing. A water pump is installed on the support legs. The inlet end of the water pump is connected to the water storage tank. The outlet end of the water pump is connected to a drain pipe. The drain pipe is annular and is sleeved on the outside of the heat-conducting rods. Uniformly distributed through holes are opened on one side of the drain pipe close to the heat-conducting rods.

[0006] Preferably, uniformly distributed rubber rings are arranged at the lower end of the housing. The inner wall of the rubber ring is in contact with the side wall of the heat-conducting rod. The rubber ring can scrape off the moisture on the heat-conducting rod.

[0007] Preferably, a motor is installed on the outer wall of the housing, a rotating shaft is installed on the output shaft of the motor, the rotating shaft penetrates the housing, and the rotating shaft is located between the first heat conducting plate and the second heat conducting plate. An eccentric rotating rod is installed on the outer side of the rotating shaft. During the rotation of the rotating rod, the second heat conducting plate can be pushed to move up and down reciprocally.

[0008] Preferably, a fixing ring is installed on the inner wall of the opening of the housing that cooperates with the rotating rod, and a dust-proof net is installed between the fixing ring and the rotating rod.

[0009] Preferably, the length of the rotating rod is greater than the width of the housing, and the rotating rod is made of a heat-conducting material.

[0010] Preferably, heat-conducting fins are provided on the part of the rotating rod located outside the housing.

[0011] Preferably, a door panel is provided on the housing, and the door panel is hermetically connected to the housing.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the transformer is in use, the motor drives the rotating shaft to rotate, the rotating shaft drives the rotating rod to rotate, and in cooperation with the spring, the second heat conducting plate is pushed to continuously move up and down reciprocally. During the movement of the heat conducting rod, the agitation of the surrounding air is accelerated, which is convenient for the heat conducting rod to dissipate heat. Moreover, when the rotating rod rotates, it can also be in full contact with the air, effectively dissipating heat.

[0014] 2. When the transformer is in use, the water pump and the drain pipe can dissipate heat from the heat conducting rod, and the water flow flushes the heat conducting rod, which is convenient for dust removal of the heat conducting rod. During the upward movement of the heat conducting rod, the rubber ring will scrape off the water on the heat conducting rod, preventing water from entering the interior of the housing and ensuring the normal operation of the transformer.
