Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer with a forced cooling structure and a use method thereof. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. It is widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] Existing transformers generate a lot of heat during daily use. In order to cool the internal resistance windings, oil is usually injected into the transformer box to soak the transformer and use the oil to dissipate heat. Although this method has the effect of heat dissipation, it still has obvious defects in actual use, such as:

[0004] When the oil dissipates heat from the transformer, its own temperature will also rise. In order to ensure that the oil can always cool the transformer, fins are installed on the surface of the transformer to naturally dissipate the oil temperature. This method can effectively reduce the temperature in seasons with low electricity consumption. However, during peak electricity consumption periods such as summer, natural cooling cannot effectively dissipate the heat in the oil, thus affecting the use of the transformer and causing failures.

[0018] Beneficial effects

[0019] The present invention provides a transformer with a forced cooling structure and a method for using the same. Compared with existing technologies, the present invention has the following advantages:

[0020] (1) The transformer with forced cooling structure and its using method are used by installing a second liquid pump and a first liquid pump on the surface and bottom of the transformer box respectively, and using them in conjunction with a cooling ring. The arrangement of these structures can use the second liquid pump and the first liquid pump to extract the oil from the inside of the transformer box and force it to circulate outside. In the process of circulation, the cooperation between the structures is used to liquid-cool and air-cool the circulating oil, thereby reducing the temperature of the oil.

[0021] (2) The transformer with forced cooling structure and its use method are characterized by installing a heat exchange inner cylinder inside the cooling ring cylinder and installing an atomizing nozzle at one end of the second liquid pipe. The arrangement of these structures enables the first pump to extract the oil and then spray it out in the form of mist using the atomizing nozzle, thereby increasing the contact area between the oil and the inner wall of the heat exchange inner cylinder, so that the coolant can dissipate heat better. At the same time, when the oil passes through the fifth liquid pipe, it can be cooled by the cooling fan for a second time, thereby ensuring the subsequent cooling quality of the transformer body.

[0022] (3) The transformer with forced cooling structure and its use method are characterized by installing a liquid storage cylinder at the rear of the transformer box, and installing a filter cylinder and a scraper plate inside the liquid storage cylinder. The arrangement of these structures allows the oil to enter the filter cylinder and be filtered first, and then be re-injected into the transformer box through the fourth liquid pipe for cooling, thereby ensuring the cleanliness of the oil. During subsequent cleaning, the filter cylinder can be pulled out from the liquid storage cylinder by twisting the knob frame, and the scraper plate can also be used to clean the inside of the filter cylinder, which is convenient for the staff to operate.

[0038] The present invention also discloses a method for using a transformer with a forced cooling structure, which specifically includes the following steps:

[0039] S1, preparation process: injecting coolant into the interior of the cooling ring 104;

[0040] S2, oil heat dissipation: atomizing the oil inside the transformer box 101 to dissipate heat;

[0041] S3, oil filtration: filter the oil flowing to the outside for cooling.

[0042] The method for using the transformer with a forced cooling structure described above includes the following more specific steps:

[0043] S1. Preparation process: Before use, first unscrew the threaded cover 111 on the surface of the injection head 109, then inject the coolant into the interior of the cooling ring 104 through the injection head 109. After the injection is completed, screw the threaded cover 111 back onto the injection head 109. At this time, the coolant inside the cooling ring 104 will cover the heat exchange inner cylinder 105;

[0044] S2. Oil heat dissipation: When in use, the transformer body 102 generates heat during operation, and the heat is first transferred to the oil inside the transformer box 101. Then, the first liquid pump 106 and the second liquid pump 112 are started at the same time. After the first liquid pump 106 is started, the oil at the top is extracted using the first liquid pipe 107, and then injected into the interior of the heat exchange inner cylinder 105 using the second liquid pipe 114. However, when the oil passes through the atomizing nozzle 108, the atomizing nozzle 108 will spray the oil in a mist over a large area, so that the mist oil adheres to the inner wall of the heat exchange inner cylinder 105 and slides down. When the oil slides down, since it is sprayed in a mist, the contact area with the heat exchange inner cylinder 105 is increased, so that the coolant can better dissipate heat. When the oil inside the heat exchange inner cylinder 105 slides to the bottom, it accumulates at the bottom of the inner cavity of the cooling ring cylinder 104.

[0045] S3, oil filtration: After the oil is at the bottom of the inner cavity of the cooling ring cylinder 104, the second liquid pump 112 uses the third liquid pipe 113 to extract the oil, and uses the fifth liquid pipe 203 and the round interface 211 to press it into the interior of the filter cylinder 207. When the oil passes through the fifth liquid pipe 203, the cooling fan 115 starts to blow air to the fifth liquid pipe 203, thereby performing secondary heat dissipation on the oil. As the oil inside the filter cylinder 207 increases, the oil will eventually pass through the process of the filter cylinder 207 and enter the fourth liquid pipe 202, and then be re-injected into the interior of the transformer box 101 through the fourth liquid pipe 202. The filter screen cartridge 207 collects impurities in the oil. When the filter screen cartridge 207 needs to be cleaned, turn off the second liquid pump 112 and the first liquid pump 106, then manually twist the knob frame 206 to separate the thread groove 210 from the threaded base 208. At this time, the sealing cover 204 is loosened, and then the filter screen cartridge 207 is pulled out of the interior of the liquid storage cylinder 201 as a whole. Then, the knob frame 206 is rotated again to separate the thread groove 210 from the threaded ring 209, and then the scraper plate 212 is pulled to scrape out the impurities on the inner wall of the filter screen cartridge 207. After cleaning is completed, the filter screen cartridge 207 and the liquid storage cylinder 201 are reinstalled.
