Introduction

The HS Series electric-furnace transformer represents a significant component in industrial furnace applications. This document elucidates its operational mechanics, unique features, and the solutions provided by the HOLEEP company in this sector.

Understanding the HS Series Electric-Furnace Transformer

Electric-furnace transformers, like the HS Series, are designed to supply the necessary power for electric arc furnaces (EAF). They efficiently convert high-voltage, low-current electricity into a low-voltage, high-current output suitable for melting processes.

HS Series Transformer Technical Specifications

• Primary Voltage: 36 kV
• Secondary Voltage: 900 V
• Rated Power Capacity: 40-120 MVA
• Frequency: 50/60 Hz
• Cooling System: ONAN/OFAN/OFWF types
• Impedance Voltage: 8-12%

Operational Principles of the HS Series Transformer

The operational workflow of an HS Series transformer involves several critical stages:

1. Primary Circuit Connection: Transformers receive electricity from the primary circuit, utilizing three-phase input power.
2. Voltage Transformation: Through electromagnetic induction, the high-input voltage is stepped down to a lower secondary voltage.
3. Secondary Output: The output spans a high current with adjustable parameters via tap changers to meet varying furnace requirements.
4. Cooling Mechanism: Designed with robust cooling units to prevent overheating during heavy operation, ensuring longevity and efficiency.
