With the rapid and steady development of China’s economy, the demand for electricity is also increasing. As the basic equipment of power transmission and transformation in the electric power industry, transformers are widely used in power plants, converter stations, substations and customer side, occupying a very important position in the electric power industry, and their demand is increasing day by day, with a very broad market prospect. This has put forward higher requirements for the production efficiency of our transformers, and along with the global energy crisis, the production of more energy-efficient transformers is also imperative. It is in this context that China’s transformer manufacturing standards have been raised again and again, and the requirements for performance indicators have become increasingly stringent.

There are two directions for the future development of transformers: one is ultra-high voltage and large capacity, and the other is high efficiency, intelligence, small size and low noise. The quality and economic and technical performance of transformers are influenced by the structural design, but also depend to a large extent on the manufacturing process and the technical level of manufacturing equipment. In order to meet the increasingly stringent requirements for transformer quality and performance indicators, we must improve the technical level of transformer foil winding machines so that they can produce and manufacture transformers that can meet the needs of national power development.

Transformers generally consist of a core, coil, shell and the necessary insulating materials. The transformer coils are generally divided into high-voltage coils and low-voltage coils. High-voltage coils are generally wound using round insulated wires, while low-voltage coils are generally made stomach with flat insulated wires or foil material. Transformer coil winding is the core process of transformer manufacturing, and has a great impact on the performance of the transformer. It not only directly determines the main economic and technical indicators such as the size, loss and weight of the transformer, but also directly affects the main quality indicators such as mechanical properties, insulation and heat resistance of the transformer. Traditional winding of transformer coils relies on manpower to wind insulated wires onto the workpiece according to the requirements of the production process, and the number of resistances is counted by the operating workers. With the traditional winding method, not only is the winding efficiency low, but the quality of the finished coil is also poor. Currently, automatic winding machines are commonly used for transformer coil winding, which can significantly improve production efficiency and line up accuracy. Among the automatic winding machines, there are vertical winding machines for large transformers, as well as horizontal winding machines and foil winding machines for transformers of lower voltage levels and smaller capacities.

The winding machine is widely used in electric power, mining machinery, furniture processing and other industries, and is a general-purpose equipment. Through the production site call on the winding machine enterprises, most of the JG series ring winding machines in use have major safety hazards, once the operation is not appropriate, not only the windings are invalid, but also may cause serious injury to human fingers. In order to reduce the scrap rate of the winding machine wing to increase safety, the addition of winding machine protection device is very necessary.
