【摘要】：大力发展节能环保产业,推广高效节能产品是当前国家的主要政策,非晶合金铁心配电变压器是配电系统首选节能环保型重要设备之一,制造厂在保证其可靠运行的同时,也在不断追求其最低成本。寻找工程成本的最优解是变压器设计的核心任务。当前我国的非晶合金变压器设计存在设计成本高、设计效率低、设计周期长,技术发展不太成熟等问题,因此有必要对上述问题进行研究。非晶合金铁心配电节能变压器由于出现的比较晚,因此与普通变压器相比,其优越性并没有得到深入的关注和研究,为此本文在设计、生产、制造和工艺等方面对非晶合金铁心配电节能变压器进行优化和改进,主要工作如下：1.对能效等级为2级的非晶合金铁心配电变压器和能效等级为3级普通油浸式配电变压器进行了计算分析,并对普通变压器与非晶合金变压器的成本消耗进行了比较。为广大变压器用户提供变压器选型依据。2.针对非晶合金变压器矩形铁心、线圈的结构特点,采用等效法和能量法进行非晶合金铁心变压器的短路阻抗计算,并把等效法应用在电磁计算中。按照圆形铁心直径与容量之间的关系,对非晶合金产品的铁心厚度与容量之间的关系进行了推导,给出计算经验公式。3.对非晶合金铁心配电节能变压器的电磁设计原则进行了介绍和分析,并在电磁设计过程中添加约束条件,通过MathCAD软件对电磁计算进行优化设计,寻求最优解。把计算结果中的关键数据参数输入到EXCEL软件中,生成计算单,通过编程及添加图形,实现该产品结构数据的参数化设计。4.从节能节材和提高效率角度出发,对非晶合金变压器的生产制造工艺进行改进,如线圈可调模具的设计、工装设备的改进,使箔式、圆筒式线圈绕制以及器身装配的生产效率得到提高。实现了生产制造成本的进一步优化。
[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.
