China Rockwill Rcs type Capswitch/Capacitor switch is a C2/C3 class special switchgear, Full complied with IEEE/ANSI C37.66 standard.
The RCS type Capswitch / Capacitor Switch
Rcs type Capswitch/Capacitor switch is a C2/C3 class special switchgear, Full complied with IEEE/ANSI C37.66 standard.
Rockwill offer you options:
Three phase solution,RCS-3N and RCS-3
Single phase solution,RCS-1
-------------------------------------------------------------
The main difference between RCS-3 and RCS-3N:
Standard RCS-3 capacitor switch is using magnetic actuator.
The normal economic type RCS-3N is using spring mechanism.
-------------------------------------------------------------
RCS-3N is upgarded type switch from RLW-24 and RLW-36 type vacuum load break switch.
General:
The Rockwill’s new generation RCS capacitor switch is a long mechnical life design vacuum switch that provides an operational life of over 100,000 (30,000open/close) maintenance-free operations.
Using the RCS will result in substantial savings from reduced maintenance and maximized bank uptime and will also improve Power Quality.
The RCS all comply with relevant standards.

Main new advantages of RCS capacitor switch

Note:
ROCKWIILL Supply special design manual closing device technology with own patent,It applied for nomal and abnormal situation closing.
Its closing speed(time) comply with IEC62271-100(GB1984-2003 standard).

| This function can offset from magnetic actuator fault when ctuator can’t work will cause the major accident..
|
Primarcy incomer terminal(directly connect to intterruter reduce power lost). Vacuum interrupter(Adopt the APG technology with external silicone rubber mold presure covering,increasing the whole insulation and weathering performance) Outlet bushing (external modular design easy for quality cotrol amd maintenanace).
 | Appy ANSOFT design the high performance magnetc actuator,high reliable and free mainten -anace. Through 35,000 times opening reverse excitation test, the demagnetization rateless than 1%.

Note:
ROCKWIILL supply special patent modular design mono-stabletype magnetic actuator with two coils controlling.Its the best
design for vacuum RCS capswitch.
