Outdoor RPS-15kV/1250A SF6 load break switch

Description：

• This is a high standard design SF6 gas load break switch which is suit for pole mounted.

• RPS type load break switch is KEMA type tested.

• RPS type load break switch can combined as below different functions switchgear:

• Manual type load break switch

• Motorize type load break switch

• Remote control load break switch

• Automatic sectionalizer

Features：

• The high quality 3 mm stainless steel are used for tank.

• 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.

• 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.

 What is a tank circuit breaker compressed air interrupter？

Working Principle：

• Working Principle: During the opening operation of the circuit breaker, the moving contact compresses the SF₆ gas within the arc quenching chamber, increasing the gas pressure and causing it to flow rapidly toward the arc region. The high-speed gas flow blows and cools the arc, effectively extinguishing it. During the closing operation, the gas returns to its original state as the moving contact moves in the opposite direction.

Features：

• Excellent Interrupting Performance: The pressurized arc quenching chamber offers excellent interrupting performance, with a short arcing time and long electrical life.

• Multiple Interruptions: It can continuously interrupt large short-circuit currents at rated voltage multiple times without frequent maintenance.

• High Mechanical Reliability: The design ensures high mechanical reliability.

• Suitable for High Voltage Systems: It is suitable for transmission and distribution systems operating at 40.5 kV and above. For example, the LW8-40.5 type SF₆ circuit breaker uses a pressurized arc quenching chamber.
