Description

Technical Field

[0001] The invention relates to the technical field of transformer equipment, and in particular to a transformer radiator, a transformer and a transport method. Background Art

[0002] A transformer is a device that transforms AC voltage, current and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core, inducing voltage in the secondary coil. The transformer consists of an iron core and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through a fixed coil, an induced potential can be generated in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting the coil changes. This is the principle of mutual induction. A transformer is a device that uses the electromagnetic mutual induction effect to transform voltage, current and impedance.

[0003] The transformer generates a lot of heat during operation. This heat mainly comes from the iron loss and copper loss inside the transformer. Iron loss is the eddy current loss and hysteresis loss generated by the transformer core under the action of the alternating magnetic field, which will cause the core to heat up. Copper loss is the resistance loss generated when the current passes through the transformer winding, which will also cause the winding to heat up. Excessive temperature will accelerate the aging of the insulation material inside the transformer, reduce its insulation performance, and even cause insulation failure. At the same time, high temperature will also accelerate the oxidation rate of the transformer oil, produce sludge and acidic substances, and further damage the insulation performance and heat dissipation capacity of the transformer. In addition, high temperature will also increase the winding resistance of the transformer, resulting in increased copper loss, forming a vicious circle. Therefore, in order to ensure the normal operation of the transformer and extend its service life, effective heat dissipation measures must be taken to effectively reduce the temperature of the transformer and improve its working efficiency and service life.

[0004] The heat dissipation methods of transformers include natural cooling, forced air cooling, water cooling, evaporative cooling and oil-immersed cooling; natural cooling is cooling by natural convection and radiation heat dissipation, but the heat dissipation effect is relatively poor, suitable for small, low-power transformers or in environments with good use conditions; forced air cooling is to install fans inside or outside the transformer to increase the air flow rate, thereby accelerating heat dissipation; water cooling uses the large specific heat capacity of water to remove the heat generated by the transformer through water circulation; evaporative cooling uses the principle of absorbing heat when liquid water evaporates into water vapor inside the transformer to dissipate heat. Oil-immersed cooling includes oil-immersed self-cooling, forced oil-air cooling and forced oil-water cooling. Among them, the oil-immersed self-cooling method is that the transformer is filled with transformer oil, and the heat is dissipated through the up and down convection of the oil. Transformers and reactors using oil-immersed self-cooling can be divided into integrated radiator type and split radiator type. For the split radiator structure, when transporting on site, in order to ensure the safety and stability of the equipment during transportation, the transformer and the radiator need to be transported separately. In the existing radiator structure, since the oil circuit of the radiator and the transformer is connected, during the split transportation process, the insulating oil in the radiator needs to be discharged, and the radiator and its oil guide pipe need to be disassembled for transportation. At the same time, after transportation and restoration of installation, the radiator needs to be vacuumed, oiled, and placed in a static state again. The entire transportation and installation cycle is long and inefficient, which affects the normal operation of the power grid. Summary of the invention

[0005] In view of the problem in the prior art that the transportation and installation period of the split oil-immersed self-cooling radiator is long and affects the normal operation of the power grid, the present invention provides a transformer radiator, a transformer and a transportation method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention provides a transformer radiator, comprising a plurality of oil guide pipes and a plurality of radiator bodies; radiator oil guide pipes are arranged at both the upper and lower ends of the radiator body; the radiator oil guide pipes at the same end are connected through the oil guide pipes; the oil guide pipe at one end is connected with a transformer oil outlet pipe; the oil guide pipe at the other end is connected with a transformer oil inlet pipe through an oil outlet pipe; oil guide pipes are arranged between the oil guide pipe and the transformer oil outlet pipe and between the oil outlet pipe and the transformer oil inlet pipe, first valves are arranged at both ends of the oil guide pipes, and a second valve is arranged on the oil guide pipes.

[0007] Optionally, a bracket is further included, and the oil guiding pipe is arranged on the bracket.

[0008] Optionally, the bracket includes a plurality of vertical support rods and a plurality of horizontal beams, and adjacent support rods are connected by the beams.

[0009] Optionally, the bracket further includes a reinforcing beam, and the reinforcing beam is connected to the supporting rod.

[0010] Optionally, the reinforcement beam is an X-shaped reinforcement beam.

[0011] Optionally, a hanging hook is provided on the bracket.

[0012] Optionally, the oil inlet pipe is connected to the oil guide pipe through a flange.

[0013] Optionally, the first valve is a butterfly valve.

[0014] The present invention provides a transformer, comprising the above-mentioned transformer heat sink.

[0015] The present invention also provides a transformer transport method as described above, comprising: Close the first valves at both ends of the oil guide pipe; After the first valve is closed, the insulating oil in the oil guide pipe is discharged; After draining the insulating oil in the oil guide pipe, disassemble the oil guide pipe, disconnect the transformer body from the radiator body, and transport them separately; After transporting to the target location, the oil pipe is installed, vacuumed, and the first valve is opened to complete the transportation of the transformer.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a transformer radiator, comprising a plurality of oil guide pipes and a plurality of radiator bodies; the upper and lower ends of the radiator body are both provided with radiator oil guide pipes; the radiator oil guide pipes at the same end are connected through the oil guide pipes; the oil guide pipes are provided as a bridge for oil conduction, and they also serve as a supporting structure of the radiator body to provide a stable support and limit for the radiator body, so that it can maintain a high degree of stability during transportation. This design not only enhances the overall structural strength of the radiator, but also reduces the risk during transportation, so that it maintains stability during transportation. At the same time, by providing oil guide pipes between the oil guide pipe and the transformer oil outlet pipe and between the oil outlet pipe and the transformer oil inlet pipe, both ends of the oil guide pipe are provided with a first valve, and the oil guide pipe is provided with a second valve. Such a design enables that when transporting, the oil circuit between the radiator body and the transformer body can be easily interrupted by closing the first valves at both ends of the oil guide pipe. Subsequently, by vacuumizing the oil guide pipe, the oil guide pipe can be easily disassembled, thereby realizing the separation of the transformer body from the radiator body. This transfer method is not only simple and convenient, but also avoids the tedious steps of draining the insulating oil in the entire radiator in the traditional method. When the transfer is completed and reassembled, just connect the oil guide pipe and evacuate, open the first valve to complete the transfer assembly. The method is simple, and there is no need to drain the insulating oil in the entire radiator, nor does it require a long vacuuming, oiling and static placement process. The oil connection between the transformer and the radiator can be quickly restored. The entire transfer and assembly process does not require complicated operations and equipment support, which greatly improves work efficiency and realizes the overall transfer of transformers and radiators to a large extent. The transfer and installation are efficient, low-cost, short-cycle, and have little impact on the normal operation of the power grid.

[0017] The setting of the bracket can provide support for the oil guide pipe and the transformer body.

[0018] The bracket includes a plurality of vertical support rods and a plurality of horizontal beams. The adjacent support rods are connected by the beams. The structure is stable, which ensures the stability and safety of the radiator during transportation. At the same time, the structure is simple, easy to process and low in cost.

[0019] The bracket also includes a reinforcing beam, which is connected to the support rod. The provision of the reinforcing beam can further enhance the stability of the framework and ensure the structural strength during overall transportation.

[0020] The reinforcing beam is an X-shaped reinforcing beam, which further ensures the stability of the structure.

[0021] The bracket is provided with a lifting hook to facilitate lifting and transportation.

[0022] The oil inlet pipe is connected to the oil guide pipe through a flange, which is convenient for early installation and later disassembly and maintenance while ensuring the stability of the connection between the two.

[0023] The first valve is a butterfly valve, which can effectively cut off the oil path between the radiator body and the transformer body.

[0024] The present invention also provides a transformer, including the above-mentioned transformer radiator. During the transportation of the transformer, it is not necessary to discharge the insulating oil in the radiator, and when reinstalling, it is not necessary to reassemble, vacuumize, fill oil and wait for the radiator, so the transportation is safe, efficient and short.

[0025] The present invention also provides a method for transporting a transformer as described above, which only requires closing the first valves at both ends of the oil guide pipe to discharge the insulating oil in the oil guide pipe; then, disassembling the oil guide pipe to disconnect the transformer body from the radiator body and transport them separately; after transporting to the target site, only the oil guide pipe needs to be installed, vacuumed, and the first valve opened to complete the transportation of the transformer. The method is simple, safe, and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
