Product Description
Specialized in the design and construction of industrial transformers
* • Pass-Through Rating up to 150 MVAr
In electric arc furnaces using long arcs and high secondary voltage values, it is often helpful to introduce additional reactors
The purpose is:
arc stability and power regulation
Optimizing electrode consumption
Limitation of current in smelting process
Reduce flicker on the feed network.
The reactor is connected in series with the furnace transformer and has some adjusting taps (for reactance adjustment)
Use an onload tap changer (OLTC) for maximum flexibility, or use a de-energized tap changer (DETC).
can assemble the reactor:
Inside the main transformer tank
Completely separated from the transformer
Located next to the transformer (on-board reactor).
In the OBR (on-board reactor) solution, the reactor and the transformer are connected by a movable cable duct.
Due to the reduction of unstable electric arc furnace current, the life cycle of the equipment is extended
High mechanical strength to withstand the lifting force caused by the increase of switching current
Tap adjustment is possible
The inductance of the reactor changes frequently, requiring large adjustment steps
Conservative temperature rise ensures extended service life
Surface treatment prevents UV radiation and contamination
Environmental protection
Maintenance-free design
