Features
The use of thyristor rectifiers can reduce the impact on the power system during ice melting and ease the switch-over operations.
The DC de-icer device supports large current and large angle continuous stable operation. It is applicable to transmission lines with different conductor diameters and lengths.
The PCS-9590/9591 DC de-icer can adopt container type installation and valve hall installation, effectively reducing land occupation, shortening the site construction time frame and easing the equipment transportation.
The device adopts reliable and compact structure with a water cooling or air cooling system and compact valve banks.
The PCS-9590/9591 is equipped with 6 phase switching disconnectors enabling the automatic switchover among various ice melting modes and realizing the balanced ice melting for AC lines.
NR Electric also provides the high performance control and protection system for DC de-icing.
Primary system of DC ice melting device requires only very small number of operations to realize SVC function.
