Application Fields
Applied in substations and transmission lines in power systems, as well as large factories and industrial parks in industrial distribution, for short-circuit current limitation and equipment protection.
Usage
Mainly connected in series in the line systems of power systems and industrial distribution. It can increase system impedance. When a fault occurs in the system, it can effectively limit the short-circuit current, reducing the fault current to within the allowable range, thereby protecting the safety of subsequent connected equipment.
Main Technical Parameters
Rated Voltage: 220kV Rated Current: 1000 ~ 6000A
Product Features
The 220kV current-limiting reactor features good linearity, simple maintenance, and safe and reliable operation. The product is equipped with grading rings to ensure uniform distribution of the electric field; the accessory transition raised seat is made of stainless steel, significantly reducing losses and temperature rise. It can effectively limit short-circuit current, simplify maintenance, operate stably, and adapt to various environments.
