Strategies and considerations for winding fixation of three-phase AC line reactors

In the manufacture and design of three-phase AC line reactors, the way of winding fixation is not only the basis for ensuring the stable operation of the equipment, but also a key factor in improving product performance and life. There are many ways to fix the windings, each of which has its own unique advantages and scope of application. Starting from the main ways of winding fixation, this paper discusses the various factors that need to be considered when choosing a fixation method, and how these factors work together to affect the overall performance and cost-effectiveness of the reactor.

Main ways of winding fixation
There are many ways to fix the windings, designed to adapt to different working environments and performance requirements. The following are several common fixing methods:
Binding fixation: The windings are tightly tied to the frame or bracket of the reactor with binding tape or rope to prevent them from loosening. This method is simple and direct, and is suitable for occasions with strict cost control and a relatively stable working environment.
Gluing fixation: The windings are firmly bonded to other parts of the reactor using adhesives such as insulating glue or epoxy resin. Gluing fixation can provide strong mechanical strength and good insulation performance, especially for high temperature or high vibration environments.
Mechanical clamping: The winding is fixed to the corresponding position of the reactor by designing a specific clamp or buckle. This method is not only firmly fixed, but also easy to repair and replace the winding, but it may increase the complexity and cost of the manufacturing process.

Comprehensive considerations for selecting the fixing method
When selecting the winding fixing method, multiple aspects such as the design requirements, working environment and cost-effectiveness of the reactor must be considered comprehensively.
Design requirements: The fixing method must meet the electrical performance requirements of the reactor, such as inductance, loss, etc. At the same time, the electromagnetic coupling effect between the winding and the core must also be considered to ensure that the reactor can work normally.
Working environment: The working environment is an important factor in selecting the fixing method. In high temperature or high vibration environments, high temperature and vibration resistant fixing materials and methods should be selected to ensure that the winding can remain stable under extreme conditions. In humid or corrosive environments, a fixing method with good moisture and corrosion resistance should be selected.
Cost-effectiveness: Cost-effectiveness is a factor that cannot be ignored in the design and manufacturing process of any product. When selecting a fixing method, the complexity of the fixing process and the material cost must be weighed to reduce the manufacturing cost while ensuring quality. For example, in some applications with strict cost control, a simple and direct binding fixation method may be preferred; in applications with high performance requirements, a more complex but better performance gluing fixation or mechanical clamping method may be selected.

There are many ways to fix the windings of three-phase AC line reactors, each with its own unique advantages and scope of application. When choosing a fixing method, it is necessary to comprehensively consider the design requirements, working environment, and cost-effectiveness of the reactor to develop the most suitable fixing strategy. By scientifically and rationally selecting a fixing method, the reactor can be ensured to maintain stable operation in a complex and changing working environment, while achieving an optimal balance between performance and cost.
