【摘要】：當(dāng)前,世界能源日益緊張,節(jié)能已經(jīng)成為全社會共同關(guān)注與研究的課題。節(jié)能不僅是經(jīng)濟(jì)上的考慮,同時對減少環(huán)境污染也有重要意義。配電變壓器作為使用最為廣泛的電力設(shè)施,數(shù)量種類繁多,降低其損耗對節(jié)能減排有著重要意義。本文研究采用新工藝、新結(jié)構(gòu)、新材料,通過改進(jìn)鐵心疊片、線圈繞制,改進(jìn)鐵心、線圈及絕緣的結(jié)構(gòu)和材料,研究開發(fā)出S14新型節(jié)能配電變壓器。(1)鐵心改進(jìn)：選用優(yōu)質(zhì)低損耗硅鋼片,鐵心結(jié)構(gòu)由圓形截面改為長圓形,保持有效截面積不變,上下鐵軛采用D型軛,有效縮小鐵心MO和窗高,增加窗口利用率,減小鐵心重量的同時減少其空載損耗。(2)線圈改進(jìn)：選用優(yōu)質(zhì)低電阻率無氧銅導(dǎo)線,線圈結(jié)構(gòu)為配套鐵心也由圓形改為長圓形,油道由全油道改為半油道,可減少銅導(dǎo)線使用量。(3)絕緣改進(jìn)：主絕緣-通過計算驗證,決定高低壓線圈間主通道處采用軟角環(huán),減小主通道間距m值；層間絕緣-導(dǎo)線由紙包線改為漆包線,極大減小線圈軸向、幅向尺寸。通過絕緣改進(jìn)可進(jìn)一步縮小鐵心MO和窗高,減少鐵心和銅導(dǎo)線重量,從而降低變壓器的空載損耗和負(fù)載損耗。通過以上改進(jìn)措施減少油浸式配電變壓器銅、硅鋼片、鐵、變壓器油等有效材料使用量,減小了油浸式配電變壓器的體積和重量,減少了原材料及變壓器生產(chǎn)過程中能源消耗和碳排放量。此S14系列油浸式配電變壓器與同容量S11型相比,空載損耗平均下降30%,負(fù)載損耗平均下降20%。推廣大量使用,將節(jié)省大量能源和材料,極大減小碳排放量,具有良好的經(jīng)濟(jì)效益和環(huán)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.
