Introduction

An iron-core shunt reactor is a specific type of equipment utilized within power transmission systems to absorb reactive power. Known for its efficiency and stability, it plays a crucial role in maintaining the voltage levels across the network. This article will outline the basic function of an iron-core shunt reactor, highlight its technical specifications, and present solutions offered by HOLEEP, a leading company in this field.

Function of an Iron-core Shunt Reactor

The primary function of an iron-core shunt reactor is to consume reactive power, thereby stabilizing the voltage on long, high-voltage transmission lines. By doing so, it controls over-voltages at low load or no load conditions, reducing stress on transmission equipment and improving overall system reliability.

Iron-core shunt reactors differ from air-core reactors by incorporating an iron core, which allows for greater efficiency in absorbing reactive power. The principle of operation involves the creation of an inductive load that counters the capacitive load of the transmission lines.

Technical Specifications and Parameters

The performance of an iron-core shunt reactor is determined by specific technical parameters:

• Rated Voltage: Typically, iron-core shunt reactors are designed to handle voltages up to 765 kV AC.
• Rated Power: These reactors generally range from 25 Mvar to over 300 Mvar.
• Impedance and Losses: Optimized to minimize energy losses (below 0.5% of rated power).
• Temperature Rise: The standard limit for temperature rise is lower than 60°C.

These parameters ensure the efficient functioning of reactors in high-voltage and dynamic load conditions.
