The Transformer - Transformer Design

The Transformer - Transformer Design 

Transformer design fundamentals refer to the basic principles and criteria by which the design, development and functioning of a transformer are established. This article outlines the essential attributes and considerations needed to create transformers that meet the specific performance standards and operating requirements to which MBT has been applied. Join us in the article below to explore the main elements that make up the Transformer Design Basis

1. Technical specifications and requirements (TRS):
This includes voltage level, current capacity, frequency, vector group, BIL, short circuit impedance and other necessary electrical parameters that the transformer should operate within. It outlines the transformer's ability to handle varying loads, voltages, transient over voltages, short circuits and efficiency.

2. ISO / IEC / IEEE standards:
Compliance with standards and TRS ensures that the transformer is constructed using high quality materials, manufacturing processes and testing procedures. This ensures product reliability and longevity. For example, standards such as IEC 60076-2, IEC 60076-3 and IEC 60076-5 provide comprehensive guidance for meeting Thermal, Dielectric and Short-circuit requirements. Additionally, ISO 9001:2015 compliance enhances management practices, thereby reducing potential product problems. MBT always complies with standards, to meet each customer with each different country's standards and to serve the most perfect export of transformers to customers.

3. Mechanical design:
Physical structure, insulation, core geometry, coil geometry, cooling system and structural integrity are very important. These aspects determine the transformer's durability, its ability to withstand environmental factors, and its safety features.

4. Reliability and performance:
The transformer must operate consistently within specified parameters, maintaining stable voltage conversion and minimal losses. The design basis ensures reliability under various conditions and loads.

5. Safety compliance:
Comply with safety standards and regulations. The transformer must be designed to pass the test, operate safely, and minimize the risk of electrical failure, overheating, fire or other potential hazards.

6. Environmental considerations:
Modern transformer designs often incorporate features that reduce environmental impact, such as the use of environmentally friendly materials, such as the use of biodegradable ester oils instead of standard mineral oils. ISO 14001:2015 standards and designed to reduce losses.

7. Life cycle and maintenance:
Long lifespan is an important aspect. The design basis includes considerations for ease of maintenance, repair, and the expected life of the transformer.

8. Cost effective:
While maintaining quality and performance, the MBT transformer design also aims for cost efficiency in manufacturing, installation and operation.

Conclude: Therefore, the Transformer Design Basis acts as a blueprint that integrates these aspects, guiding engineers and manufacturers to create transformers that meet or exceed performance expectations.
