SF6 gas insulated Load break switch motorize type

- SF6 gas insulated sectionazlizer

-SF6 Gas insulated load break switch (SF6 gas insulated switch disconnector) type RPS-12/27/38-20 is suitable for the rated voltage up to 40.5kV,rated current 400A-630A, 50/60Hz power system.

-RPS is a SF6 gas breaking on load break switch, ie. on load switch disconnector. It can be upgraded as a On load type automatic sectionalier.
Rated voltage: up to 40.5 kV
Rated current: 400 to 630 A
Insensitive to the environment.

Options:

E2/E3

Manual or remote control

CT/PT/VS
Gas pressure guage

Low pressure lockout

SCADA capabilities
etc...

RPS is an SF6-insulated, outdoor pole mounted load break switch family for overhead lines and specifically designed for use in modern remote controlled distribution automation systems.


The RPS offers reliable maintenance free operation even in the most demanding climatic conditions including salt laden atmospheres, corrosive industrial pollution, snow and ice.

It has excellent load breaking and fault making capacity and satisfies the isolation requirements specified for load break switch. The earthed metal tank prevents all possible leakage currents across an open switch. RPS can be manually operated or motor operated for local and remote electric control, upgraded.

● RPS feature
The high quality 3 mm stainless steel are used for tank, which is designed for its maximum robustness and minimum welding line to minimize corrosion, and specifically to guarantee the safety of the operation personnel even with the internal arc faults at the maximum fault capacity of the tank the RPS can withstands an internal fault without venting hot gases.
The independent spring operation mechanism adopt ROCKWILL® patent spiral spring, provides a guaranteed load break fault make capability by ensuring the opening and closing speed of the switch.
The RPS is provided with light reflecting position indicator which are directly connected to the switch operating shaft providing clear and unambiguous switch position indication. Indicator made of light reflecting material, which is easily visible from ground level even at night in driving rain.
● Main new advantages of RPS
ROCKWILL® Supply special design manual closing device technology with own patent, It applied for normal and abnormal situation closing. It’s closing speed(time) comply with IEC62271-100.
This function can offset from magnetic actuator fault which when actuator can’t work will cause the major accident.
Corrosion resistant, Composite bushingManual lock-out mechanism (including hook stick) Reliable housing groundO/C indicator (made of light reflecting material), Operation counter, Gas density gauge which are easily visible from ground level.
Advanced and Integrated helium leakage detecting and filling equipment, which ensuring SF6 leakage of each switch is less than 0.1% strictly per year.
Motor drive, which easily retrofitted on site to manually operated units.
