Detailed Introduction to Components of German Standard Low-Voltage Transformer Bushings

German Standard Low-Voltage Transformer Bushings (DIN low-voltage transformer bushings) are critical components in power transmission and distribution systems. The design and function of each component are crucial for the overall performance and reliability of the bushings. This article provides a detailed introduction to these components and their functions.

1. Bushing Body

The bushing body is the core component of the transformer bushing, typically made of high-strength porcelain. It provides electrical insulation and mechanical support, ensuring the safe transmission of current between high and low voltage. The bushing body of German standard low-voltage transformer bushings has excellent heat resistance and mechanical impact resistance, maintaining stable performance even in harsh environments.

2. Conductor

The conductor is the core conductive part inside the bushing, responsible for transmitting current from the inside of the transformer to the external power grid. Usually made of high-conductivity copper or aluminum, the design of the conductor must consider not only electrical performance but also mechanical strength and thermal expansion coefficient to ensure stability during long-term operation.

3. Flange

The flange is the key component connecting the bushing to the transformer housing, fixed to the transformer through bolts or welding. The precise design of the flange in German standard low-voltage transformer bushings provides a solid mechanical connection and good sealing performance, preventing oil leakage and contamination from entering the transformer.

4. Sealing Components

Sealing components ensure that the insulating oil or gas inside the transformer does not leak and prevent external moisture and contaminants from entering. Common sealing materials include rubber and silicone, and the sealing design of German standard low-voltage transformer bushings strictly follows standards, offering excellent sealing performance and durability.

5. Terminal

The terminal is the external connection part of the conductor, used to connect external cables or wires. The design of the terminal must consider contact resistance and mechanical strength, usually made of tin-plated copper or aluminum alloy. The terminals of German standard low-voltage transformer bushings are compact, easy to install, and ensure reliable electrical connections over the long term.

6. Shielding Components

Shielding components prevent electric field interference and improve the electrical insulation performance of the bushings. German standard low-voltage transformer bushings typically have shielding layers inside or outside the bushing body, effectively reducing electric field distortion and partial discharge phenomena, enhancing the overall electrical performance of the bushing.

Conclusion

The components of German standard low-voltage transformer bushings are designed and selected according to strict German industrial standards to ensure high reliability and long service life. The coordination and optimized design of these components enable German standard low-voltage transformer bushings to operate stably in various complex environments, making them an important part of power systems.

Through the above detailed introduction, it is hoped that readers have a deeper understanding of German standard low-voltage transformer bushings, and that this information can help electrical engineers and related technical personnel make more informed decisions when selecting and using bushings.
