Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer cooling oil diversion system and a cooling method. 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 are voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. It is the basic equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] When existing transformers are running, the internal resistors generate a lot of heat. In order to effectively dissipate the heat and ensure stable power supply, oil is generally injected into the transformer box in advance to cool and insulate the resistors.

[0014] Beneficial effects The present invention provides a transformer cooling oil diversion system and cooling method.

The arrangement of these structures can first use a buffer baffle to slow down the flow speed after the oil reaches the inside of the load-bearing bottom frame, and then let the fan blow air inside the second heat dissipation pipe to take out the heat.

[0016] (3) The transformer cooling oil diversion system and cooling method are characterized by installing a protective baffle on one side of the inclined baffle frame to cooperate with the filter mesh port. The arrangement of these structures can first use the filter mesh port and the protective baffle to protect the interior of the liquid storage box to prevent impurities and insects from entering. At the same time, the protective baffle can be pushed open for exhaust when the air flow rises, thereby ensuring the stability of the equipment during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention also discloses a cooling method for a transformer cooling oil guide system, which specifically comprises the following steps: S1. Preparation process: Install the transformer body 103 inside the transformer box 102 and inject oil at the same time; S2, oil heat dissipation: using the material pump 107 to circulate the oil as a whole and dissipate heat; S3, exhaust reflux: utilize gas to dissipate the heat in the oil, and then discharge it through the filter mesh port 112.

[0023] The cooling method of the transformer cooling oil diversion system mentioned above has the following more specific steps: S1. Preparation process: Before use, first install the transformer body 103 into the interior of the transformer box 102, then fill the transformer box 102 with oil. After the oil enters the transformer box 102, it will first enter the interior of the load-bearing bottom frame 201 through a plurality of liquid guide bottom pipes 105. The interior of the transformer box 102 will not start to accumulate oil until the load-bearing bottom frame 201 is filled. Stop filling the oil after the oil reaches the bottom of the return liquid frame 110, and then seal and install the entire device. S2, oil heat dissipation: when in use, after the transformer body 103 is started, the heat will be transferred to the oil first, and the arrangement of the first heat dissipation pipes 104 can extract the heat in the oil, and at the same time, the fan 202 and the material pump 107 are started synchronously. After the material pump 107 is started, the oil inside the load-bearing bottom frame 201 is pumped out by the liquid suction pipe 108, and then the oil is injected into the liquid storage rear box 106 by the liquid pressure pipe 109. At this time, the oil inside the transformer box 102 will enter the load-bearing bottom frame 201 again through the liquid guide bottom pipe 105. At this time, the start of the fan 202 blows air to the inside of the second heat dissipation pipe 203. When the air flows through the inside of the second heat dissipation pipe 203, the inner wall of the entire second heat dissipation pipe 203 and the X-shaped plate 206 increase the contact area with the wind, thereby being able to take out a large amount of heat in the oil. At the same time, when the liquid suction pipe 108 is extracting the oil, the function of the buffer baffles 204 can slow down the flow speed of the oil, thereby improving the heat dissipation efficiency; S3, exhaust backflow: After the oil liquid that has completed the initial heat dissipation is pumped into the return liquid matrix frame 110 by the material pump 107, the air flow inside the second heat dissipation pipe 203 is compressed by the wind hood 207, and then injected into the inner side of the curved pipe frame 114 through the air guide straight pipe 208, and then the fast-flowing gas enters the bottom of the liquid storage rear box 106 through several vertical air long pipes 115. After the air flow is released in the oil, the oil inside the liquid storage rear box 106 will roll, and a large number of bubbles will float to the surface and break, thereby overflowing the heat in the oil again, and then the gas floats up with the heat, and then pushes open the protective baffle 113 and is discharged from the filter mesh port 112. The oil inside the liquid storage rear box 106 is continuously injected, so that when it reaches the return liquid matrix frame 110, it will flow back into the interior of the transformer box 102 for cooling.
