JB/T10775 Dry Type Reactor

Dry Iron Core Reactor,Current Limiting Reactors

1.Overview of Dry Iron Core Reactor

The iron core reactor is mainly composed of an iron core and a winding. The winding is sleeved outside the iron core column, and the winding is usually made of insulated copper wire. The magnetic flux path of this kind of reactor is the iron yoke and the iron core column with gaps. Since the permeability of the magnetic material is much larger than that of air, the iron core reactor of the same capacity is smaller than the air core reactor.

 2. Purpose of Dry Iron Core Reactor

It is used in the high voltage parallel circuit of 35kV and below power system and high-speed rail power supply system. It transmits inductive reactive power through the main variable direction system to compensate the capacitive current of the transmission line, prevent the voltage of the light load line from rising, and maintain the voltage stability of the transmission system. Sex, improve power factor of power system and save energy.

3. Main features of Dry Iron Core Reactor

• Silicon steel sheet as magnetic medium
• Magnetic flux with iron core as magnetic circuit
• No electromagnetic pollution to the surrounding environment
• Coil insulation heat resistance grade can be F grade, H grade, etc.
• Low vibration and low noise during exercise
• Small footprint.​​
