If you are looking for a durable and cost-effective solution, this guide will help you understand everything about the 2000kVA-Transformator, including specifications, working principles, Anwendungen, and how DOS Group can support your project with professional manufacturing and global supply.
What Is a 2000kVA Transformer?
A 2000kVA-Transformator is an electrical device designed to transfer electrical energy between circuits with a rated capacity of 2000 Kilovoltampere (KVA), which is equal to:
- 2000kVA = 2MVA
It is commonly used to step down medium voltage (MV) to low voltage (LV) for end users or step up voltage in power systems.
Key Features:
- High load capacity
- Stable voltage regulation
- Lange Lebensdauer
- Suitable for continuous operation
How Does a 2000kVA Transformer Work?
The operation of a transformer is based on elektromagnetische Induktion.
Simple Working Process:
- Alternating current flows into the primary winding
- A magnetic field is created in the core
- This magnetic field induces voltage in the secondary winding
- Voltage changes according to the turns ratio
Basic Formula:
- Spannungsverhältnis = Windungsverhältnis
- Die Leistung bleibt nahezu konstant (minus losses)
This simple principle allows efficient transmission of electrical energy over long distances.
Types of 2000kVA Transformers
Different environments require different transformer types. The most common types include:
1. Öltransformator
- Uses insulating oil for cooling
- Excellent heat dissipation
- Suitable for outdoor installations
- Long lifespan
2. Trockentransformator
- Luftgekühlt, kein Öl
- Safer for indoor use
- Low fire risk
3. Transformator aus Gießharz
- Encapsulated windings
- High resistance to moisture and dust
- Ideal for harsh environments
