【摘要】：当前,世界能源日益紧张,节能已经成为全社会共同关注与研究的课题。节能不仅是经济上的考虑,同时对减少环境污染也有重要意义。配电变压器作为使用最为广泛的电力设施,数量种类繁多,降低其损耗对节能减排有着重要意义。本文研究采用新工艺、新结构、新材料,通过改进铁心叠片、线圈绕制,改进铁心、线圈及绝缘的结构和材料,研究开发出S14新型节能配电变压器。(1)铁心改进：选用优质低损耗硅钢片,铁心结构由圆形截面改为长圆形,保持有效截面积不变,上下铁轭采用D型轭,有效缩小铁心MO和窗高,增加窗口利用率,减小铁心重量的同时减少其空载损耗。(2)线圈改进：选用优质低电阻率无氧铜导线,线圈结构为配套铁心也由圆形改为长圆形,油道由全油道改为半油道,可减少铜导线使用量。(3)绝缘改进：主绝缘-通过计算验证,决定高低压线圈间主通道处采用软角环,减小主通道间距m值；层间绝缘-导线由纸包线改为漆包线,极大减小线圈轴向、幅向尺寸。通过绝缘改进可进一步缩小铁心MO和窗高,减少铁心和铜导线重量,从而降低变压器的空载损耗和负载损耗。通过以上改进措施减少油浸式配电变压器铜、硅钢片、铁、变压器油等有效材料使用量,减小了油浸式配电变压器的体积和重量,减少了原材料及变压器生产过程中能源消耗和碳排放量。此S14系列油浸式配电变压器与同容量S11型相比,空载损耗平均下降30%,负载损耗平均下降20%。推广大量使用,将节省大量能源和材料,极大减小碳排放量,具有良好的经济效益和环保效益耗。
[Abstract]:At present, the world energy is increasingly tense, energy conservation has become a common concern and research of the whole society. Energy-saving is not only an economic consideration, but also important to reduce environmental pollution. As the most widely used power facilities, distribution transformers are of great importance to energy saving and emission reduction. In this paper, new technologies, new structures, new materials are used to improve the structure and materials of iron cores, coils and insulation by improving the core lamination, coil winding, and improvement of the core, coil and insulation. A new type of energy saving distribution transformer S14 has been developed. (1) improvement of iron core: selecting high quality low loss silicon steel sheet, changing core structure from circular section to oblong, keeping effective cross section unchanged, and adopting D yoke for upper and lower iron yoke, Effectively reduce the core MO and window height, increase window utilization, reduce the weight of the core and reduce its no-load loss. (2) Coil improvement: select high-quality low resistivity oxygen free copper wire, coil structure for matching iron core is changed from circular to oblong, If the oil channel is changed from the whole oil channel to the half oil channel, the usage of copper wire can be reduced. (3) Insulation improvement: the main insulation-the main channel between high and low voltage coils is determined to adopt soft corner ring to reduce the m value of the main channel spacing. Interlaminar insulation-wire changed from paper-wrapped wire to enamelled wire, greatly reducing the axial and amplitude dimensions of the coil. Through the insulation improvement, the core MO and window height can be further reduced, and the weight of the core and copper conductor can be reduced, thus reducing the no-load loss and load loss of the transformer. The volume and weight of oil-immersed distribution transformer can be reduced by reducing the amount of effective materials such as copper, silicon steel sheet, iron, transformer oil and so on. Reduced raw materials and transformer production process energy consumption and carbon emissions. Compared with the same capacity S11, this S14 series oil-immersed distribution transformer has an average no-load loss of 30 and an average load loss of 20. It can save a lot of energy and materials, greatly reduce carbon emissions, and has good economic and environmental benefits.
