Qingdao Yunlu Energy Technology Co., Ltd.
As a type of current liming reactor, the 2450A/0.57mH water-cooled anode saturable reactor is used for high voltage direct current (HVDC) ±500KV converter valve components. As an electrical component, this high voltage reactor has two main functions:
1. To restrict the SCR triggered current increase rate (di/dt);
2. To restrict the instantaneous steep wave front impulse voltage of the SCR.
