The application of autodeskinventor in transformer structure design

transformation from 2D to 3D

Shenyang Transformer Research Institute (STI), founded in 1960, is a modern high-tech enterprise with strong scientific research and development capabilities. STI has undertaken, organized and completed dozens of national major scientific and technological research projects, achieved fruitful scientific research results, won 34 national, provincial and ministerial scientific and technological progress awards, and software technology has been widely used in more than 500 enterprises in the transformer industry. STI has also established the world's first-class domestic largest strong current inspection room and the domestic first-class transformer test base, which have close working relations with internationally renowned electrical laboratories such as Kema laboratory in the Netherlands and CESI laboratory in Italy, which can meet the test requirements of 500kV and below transformer products and provide sufficient test conditions for improving the short-circuit resistance of Chinese transformer products

the main work of my department is: facing the transformer industry, I am committed to the development of software related to transformer products. It mainly includes structural optimization design of various new products, electromagnetic calculation optimization design and transformer engineering analysis and calculation; Promote the application of industry computer 3D visual design technology, and improve the application level of industry digital technology in production, manufacturing, testing, management and operation

although STI has won many honors, it also has many customers. However, with the development of technology and the improvement of demand, there are still some technologies that need to be solved urgently in the actual production work. Among them, HRC is second only to Brinell hardness Hb in steel pipe standards, including:

(1) how to communicate better and more effectively with customers

(2) calculation of core and coil in transformer design

(3) the existing wiring methods need to be manually calculated for a long time

(4) the consistency of parts design data cannot be guaranteed

(5) problems caused by modifying associated files in the design

the above problems are prominent in the actual work process. Due to their existence, they may affect the design cycle and design quality of the transformer at least, and may affect the market prospect and customer satisfaction of the product at most

based on the uniqueness of the product, most of the coils of transformer products are made by manual operation, so it is still inseparable from two-dimensional engineering drawings. For two-dimensional parametric drawings, it is convenient to apply AutoCAD programming. However, the lead wire layout of large transformers is complex. For these reasons, STI began to prepare the upgrade of the design platform from 2D software to 3D software, and began to select the software

at the early stage of model selection, we learned and tried many 3D software, including AIP, pro/engineer, SolidWorks and SolidEdge, which are widely used at present. The company finally chose Inventor software through the investigation of the software's operability, design, stress analysis function and compatibility with other software. Compared with other software to be selected, Inventor software is the most suitable for the current situation of our institute. Due to the convenient interface with AutoCAD, the high utilization rate of the original DWG files, the reasonable price and the convenience for industry promotion, it is believed that it can help us solve the thorny problems we encounter in practice

in the trial stage, Inventor software has shown good performance and significantly improved the design efficiency. Taking the design of a three winding on load transformer with a voltage class of 110 kV and a capacity of 63000 KVA as an example, it used to be designed manually, which took about 5 people and 10 days to complete; With this system design, it only takes 2 people and 6 days to complete, and the design efficiency is improved by 4~5 times. After trial 2 Accuracy level: 0.5. We have purchased 30 sets of Inventor software, which are mainly used by the product development department and the software development department to complete the product design and the development of the transformer 3D design system platform

in transformer structure design, many problems such as electricity, magnetism, heat, force and field are involved. Taking transformer lead design as an example, this paper illustrates the role of Inventor software in product design

transformer lead setting is also an urgent problem to be solved in the field of fire public safety. It has the characteristics of many related factors, large structural changes and complex drawing representation. Two dimensional engineering drawing of medium and low voltage leads of sfz/110 transformer is shown in Figure 1. If the two-dimensional software design is applied to this kind of structure alone, the drawing workload will be very large without considering the time of structural calculation. Once the structure changes, leading to changes in the lead routing, the corresponding wood clamping structure will also change, so the whole drawing will be redesigned, which will take a lot of time. 1. Connect the power line

Figure 1 engineering drawing of transformer leads

in recent years, with the successful development of transformer professional design platform system, the workload of designing transformer leads has been significantly reduced. Due to the limitation of the platform, the structural design is not flexible enough. Software developers often win by quantity (that is, increasing the number of templates for various structures). However, the wiring needs to be calculated and the workload is very large. Lead wiring has also become a bottleneck in the development of transformer 3D design software. The author has been engaged in the development of the lead part of the transformer 3D design system for many years, and has been exposed to a variety of 3D design platforms. Through comparison, it is considered that the "pipe routing" function of Inventor software is an effective method to solve this bottleneck

inventor software "pipe routing" module, as shown in Figure 2. This routing method is almost impossible if it is completed by manual calculation, while the application of "pipe routing" module only needs to add ten harnesses, which can be completed in a few minutes. In addition, the generated harness has an adaptive function. No matter how the structure changes, Inventor software will automatically calculate, so that the laid lines can adapt to the new structure, greatly reducing the workload of developers. This feature is illustrated by an example below

Figure 2 "pipe routing" module

first, other parts need to be assembled (or not all of them, because the laid lines can add "work points" at any time to change the line layout, which is another embodiment of the flexibility of the software), because the application of "pipe routing" requires the selection of some points to determine the line direction. Then, select the create harness command on the assembly panel of the open assembly drawing to open the dialog box
