Description
技术领域Technical Field
本发明涉及油浸式变压器技术领域，具体为一种油循环冷却式电力变压器。The invention relates to the technical field of oil-immersed transformers, in particular to an oil circulation cooling type power transformer.
背景技术Background technique
油浸式变压器是一种常见的电力设备，用于将高电压变换为低电压或反之，同时保证电力传输的效率和安全性，主要由油浸式的绝缘系统和铁芯绕组组成，绝缘油不仅作为电气绝缘材料，还具有冷却、防腐、灭弧等功能。当变压器工作时，绝缘油充当绝缘介质，确保绕组间的电场稳定分布，防止击穿和放电，变压器在工作时会产生一定的热量，绝缘油承担了将这些热量传导到变压器外壳表面的任务。外部散热器通过对绝缘油的冷却来控制变压器的工作温度，保持其在安全范围内，随着变压器长时间运行，绝缘油中会积累一些沉淀物和杂质，可能会影响变压器的性能和寿命。为了保持绝缘油的清洁，通常设计有各种清洁装置和排污系统，定期排除沉淀物和杂质。Oil-immersed transformer is a common power equipment used to convert high voltage to low voltage or vice versa, while ensuring the efficiency and safety of power transmission. It is mainly composed of oil-immersed insulation system and iron core winding. Insulating oil not only serves as electrical insulation material, but also has cooling, anti-corrosion, arc extinguishing and other functions. When the transformer is working, the insulating oil acts as an insulating medium to ensure the stable distribution of the electric field between the windings and prevent breakdown and discharge. The transformer will generate a certain amount of heat when working, and the insulating oil is responsible for conducting this heat to the surface of the transformer casing. The external radiator controls the operating temperature of the transformer by cooling the insulating oil to keep it within a safe range. As the transformer runs for a long time, some sediment and impurities will accumulate in the insulating oil, which may affect the performance and life of the transformer. In order to keep the insulating oil clean, various cleaning devices and sewage systems are usually designed to remove sediment and impurities regularly.
现有的油浸式变压器长时间使用后，油浸式变压器内部会产生高压和高温的环境，油在高温和高压条件下容易氧化和降解，形成酸性物质和沉淀物。且随着时间的推移，油中可能会渗入水分和吸收污染物，例如灰尘、金属颗粒或其他杂质，这些污染物可能会导致油的绝缘性能下降，并增加油浸式变压器的摩擦和磨损的氧化和水分渗入会降低其绝缘性能，增加变压器内部短路的风险，变压器油中的酸性物质和沉淀物会影响其流动性和散热能力，导致变压器运行温度升高，影响效率和寿命，酸性物质可以腐蚀变压器内部的金属部件，包括绕组和核心，这可能导致设备性能下降和维护成本增加，且在变压器运行期间，油中的高温和高压可能导致气体的产生，例如氢气和甲烷，这些气体可能积聚在油中，形成气泡，降低油的绝缘性能，并增加油浸式变压器内部的压力。After the existing oil-immersed transformers have been used for a long time, a high-pressure and high-temperature environment will be generated inside the oil-immersed transformer. The oil is easily oxidized and degraded under high-temperature and high-pressure conditions, forming acidic substances and sediments. And over time, the oil may penetrate moisture and absorb pollutants such as dust, metal particles or other impurities, which may cause the oil's insulation performance to deteriorate and increase the friction and wear of the oil-immersed transformer. Oxidation and moisture penetration will reduce its insulation performance and increase the risk of short circuits inside the transformer. Acidic substances and sediments in the transformer oil will affect its fluidity and heat dissipation capabilities, causing the transformer to operate at an increased temperature, affecting efficiency and life. Acidic substances can corrode metal parts inside the transformer, including windings and cores, which may lead to equipment performance degradation and increased maintenance costs. During the operation of the transformer, the high temperature and high pressure in the oil may lead to the generation of gases, such as hydrogen and methane, which may accumulate in the oil, forming bubbles, reducing the oil's insulation performance, and increasing the pressure inside the oil-immersed transformer.

本发明具有以下有益效果：The present invention has the following beneficial effects:
1、该油循环冷却式电力变压器，通过刷毛与电磁绕组相互接触，使球轴在球槽内进行旋转运动，使刷毛方便将电磁绕组表面的附着物进行清理干净，刷毛与电磁绕组相互接触，能够有效地清理电磁绕组表面的附着物，如灰尘、油污等，保持电磁绕组的表面清洁，有助于减少电磁绕组的温度上升，提高油浸式变压器的散热效率，延长油浸式变压器的使用寿命，球轴在球槽内进行旋转运动，使得刷毛能够覆盖到电磁绕组表面的各个部分，清洁效果更加均匀，提高清洁效率，特别是在大型油浸式变压器等设备中，效果更为显著。1. The oil circulation cooling power transformer makes the brush bristles contact with the electromagnetic winding, so that the ball shaft rotates in the ball groove, so that the brush bristles can easily clean the attachments on the surface of the electromagnetic winding. The brush bristles contact with the electromagnetic winding, which can effectively clean the attachments on the surface of the electromagnetic winding, such as dust, oil stains, etc., and keep the surface of the electromagnetic winding clean, which helps to reduce the temperature rise of the electromagnetic winding, improve the heat dissipation efficiency of the oil-immersed transformer, and extend the service life of the oil-immersed transformer. The ball shaft rotates in the ball groove, so that the brush bristles can cover all parts of the surface of the electromagnetic winding, and the cleaning effect is more uniform, which improves the cleaning efficiency, especially in large oil-immersed transformers and other equipment, the effect is more significant.
2、该油循环冷却式电力变压器，通过风扇片对电磁绕组表面进行吹动，能够有效地降低电磁绕组的温度，提高油浸式变压器的冷却效果，有助于保持油浸式变压器在正常工作温度范围内，防止过热引发的故障，风扇片的往复旋转运动能够带动浸油箱内部的油液产生搅拌，使油液更加均匀地流动，有助于散热和冷却效果的提升，可以防止油液局部过热或产生死角，保持油液的温度均匀性和稳定性，风扇片搅拌油液消除气泡，减少这些局部空隙的存在，提高了绝缘油的绝缘性能，从而保障油浸式变压器的安全运行，且搅拌油液消除气泡，可以使油液更加均匀地分布，有助于消除局部热点，提高油浸式变压器的散热效率，延长设备的使用寿命。2. The oil circulation cooling power transformer can effectively reduce the temperature of the electromagnetic winding and improve the cooling effect of the oil-immersed transformer by blowing the surface of the electromagnetic winding through the fan blades, which helps to keep the oil-immersed transformer within the normal operating temperature range and prevent failures caused by overheating. The reciprocating rotation of the fan blades can drive the oil inside the oil immersion tank to stir, so that the oil flows more evenly, which helps to improve the heat dissipation and cooling effect, prevent local overheating of the oil or dead corners, and maintain the temperature uniformity and stability of the oil. The fan blades stir the oil to eliminate bubbles, reduce the existence of these local gaps, and improve the insulation performance of the insulating oil, thereby ensuring the safe operation of the oil-immersed transformer. Stirring the oil to eliminate bubbles can make the oil more evenly distributed, which helps to eliminate local hot spots, improve the heat dissipation efficiency of the oil-immersed transformer, and extend the service life of the equipment.
3、该油循环冷却式电力变压器，通过吸油管和倾斜吸管将浸油箱内的油吸入，然后通过输油管将油送回到储油箱，实现了油的循环流动，循环油泵的作用在于维持油的循环，以保持油浸式变压器内部的温度在安全范围内，并有效冷却电磁绕组，加油泵通过第二出油管将储油箱内的油吸入，然后通过第一出油管将油加入到浸油箱内，加油泵以维持浸油箱内部油的足够量，确保油浸式变压器的正常运行和绝缘性能。3. The oil circulation cooling power transformer sucks the oil in the oil immersion tank through the oil suction pipe and the inclined suction pipe, and then sends the oil back to the oil storage tank through the oil delivery pipe, realizing the circulation of oil. The function of the circulating oil pump is to maintain the circulation of oil to keep the temperature inside the oil-immersed transformer within a safe range and effectively cool the electromagnetic winding. The refueling pump sucks the oil in the oil storage tank through the second oil outlet pipe, and then adds the oil to the oil immersion tank through the first oil outlet pipe. The refueling pump maintains a sufficient amount of oil inside the oil immersion tank to ensure the normal operation and insulation performance of the oil-immersed transformer.
4、该油循环冷却式电力变压器，通过吸污腔、除污管道和球阀门相互配合，打开球阀门，使大量少量油液、沉淀物和杂质从除污管道排出，部分沉淀物和杂质被吸入吸污腔内，从而有效清除了油液中的杂质，防护网的设计可以阻止大量的沉淀物和杂质进入倾斜吸管内，确保吸入的油液相对清洁，定期排出大量少量的沉淀物和杂质可以保持油液的清洁度，有助于维持油浸式变压器的正常运行。4. The oil circulation cooling power transformer cooperates with the dirt suction chamber, the dirt removal pipeline and the ball valve. When the ball valve is opened, a large amount of oil, sediment and impurities are discharged from the dirt removal pipeline, and part of the sediment and impurities are sucked into the dirt suction chamber, thereby effectively removing impurities in the oil. The design of the protective net can prevent a large amount of sediment and impurities from entering the inclined suction pipe, ensuring that the sucked oil is relatively clean. Regularly discharging a large amount of sediment and impurities can maintain the cleanliness of the oil, which is helpful to maintain the normal operation of the oil-immersed transformer.
当然，实施本发明的任一产品并不一定需要同时达到以上所述的所有优点。Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned advantages at the same time.

By blowing the surface of the electromagnetic winding 4 by the fan sheet 764, the temperature of the electromagnetic winding 4 can be effectively reduced, and the cooling effect of the oil-immersed transformer 1 can be improved. It helps to keep the oil-immersed transformer 1 within the normal operating temperature range and prevent malfunctions caused by overheating. The reciprocating rotation of the fan blades 764 can drive the oil inside the oil immersion tank 5 to stir, allowing the oil to flow more evenly, which helps to improve the heat dissipation and cooling effects, and can prevent local overheating of the oil or dead corners, and maintain the temperature uniformity and stability of the oil.
