【摘要】:大力發(fā)展節(jié)能環(huán)保產業(yè),推廣高效節(jié)能產品是當前國家的主要政策,非晶合金鐵心配電變壓器是配電系統(tǒng)首選節(jié)能環(huán)保型重要設備之一,制造廠在保證其可靠運行的同時,也在不斷追求其最低成本。尋找工程成本的最優(yōu)解是變壓器設計的核心任務。當前我國的非晶合金變壓器設計存在設計成本高、設計效率低、設計周期長,技術發(fā)展不太成熟等問題,因此有必要對上述問題進行研究。非晶合金鐵心配電節(jié)能變壓器由于出現的比較晚,因此與普通變壓器相比,其優(yōu)越性并沒有得到深入的關注和研究,為此本文在設計、生產、制造和工藝等方面對非晶合金鐵心配電節(jié)能變壓器進行優(yōu)化和改進,主要工作如下:1.對能效等級為2級的非晶合金鐵心配電變壓器和能效等級為3級普通油浸式配電變壓器進行了計算分析,并對普通變壓器與非晶合金變壓器的成本消耗進行了比較。為廣大變壓器用戶提供變壓器選型依據。2.針對非晶合金變壓器矩形鐵心、線圈的結構特點,采用等效法和能量法進行非晶合金鐵心變壓器的短路阻抗計算,并把等效法應用在電磁計算中。按照圓形鐵心直徑與容量之間的關系,對非晶合金產品的鐵心厚度與容量之間的關系進行了推導,給出計算經驗公式。3.對非晶合金鐵心配電節(jié)能變壓器的電磁設計原則進行了介紹和分析,并在電磁設計過程中添加約束條件,通過MathCAD軟件對電磁計算進行優(yōu)化設計,尋求最優(yōu)解。把計算結果中的關鍵數據參數輸入到EXCEL軟件中,生成計算單,通過編程及添加圖形,實現該產品結構數據的參數化設計。4.從節(jié)能節(jié)材和提高效率角度出發(fā),對非晶合金變壓器的生產制造工藝進行改進,如線圈可調模具的設計、工裝設備的改進,使箔式、圓筒式線圈繞制以及器身裝配的生產效率得到提高。實現了生產制造成本的進一步優(yōu)化。
[Abstract]:It is the main policy of our country to develop energy saving and environmental protection industry and to popularize high efficiency energy saving products. The amorphous alloy iron core distribution transformer is one of the most important equipments of energy saving and environmental protection in distribution system. The manufacturer ensures its reliable operation at the same time. The core task of transformer design is to find the optimal solution of engineering cost. At present, the design of amorphous alloy transformer in our country has high design cost, low design efficiency and long design period. Since the technology development is not mature, it is necessary to study the above problems. The amorphous alloy iron core distribution energy saving transformer appears late, so it is compared with the ordinary transformer. Its superiority has not been deeply concerned and studied. Therefore, this paper optimizes and improves the amorphous alloy iron core distribution energy saving transformer in design, production, manufacture and process. The main work is as follows: 1.Computation and analysis of amorphous alloy core distribution transformer with energy efficiency grade 2 and ordinary oil-immersed distribution transformer with energy efficiency grade 3. The cost consumption of ordinary transformers and amorphous alloy transformers is compared, and the basis of transformer selection is provided for the majority of transformer users. 2. According to the structural characteristics of rectangular cores and coils of amorphous alloy transformers. The short circuit impedance of amorphous alloy core transformer is calculated by using the equivalent method and the energy method, and the equivalent method is applied to the electromagnetic calculation according to the relation between the diameter of the circular core and the capacity. The relationship between the core thickness and the capacity of amorphous alloy products is deduced, and the formula of calculation experience is given. 3. The electromagnetic design principle of amorphous alloy core distribution energy saving transformer is introduced and analyzed. In the process of electromagnetic design, the constraint conditions are added, and the electromagnetic calculation is optimized by MathCAD software to find the optimal solution. The key data parameters in the calculation results are input into the EXCEL software. Through programming and adding graphics, the parameterized design of the product structure data is realized. 4. From the point of view of saving energy, saving materials and improving efficiency, the manufacturing process of amorphous alloy transformer is improved. For example, the design of coil adjustable die and the improvement of tooling equipment can improve the production efficiency of foil type, cylindrical coil winding and assembly of the body, and realize the further optimization of production cost.
