SF6 Electrical Load Break Switch 10kV 630A Compact Size For Gas Insulated Switchgear

Medium Voltage RMU SF6 Load Break Switch 10kV 630A For Incoming Line

FLN36-12kV SF6 load break switch is a switch equipment for medium voltage switchgear, using SF6 gas as arc extinguishing and insulating medium. There are three working positions: open, closed, and earth position in the switch. The compact size, easy installation, and fine adaptability to the environment make the switch suitable for many different applications.

It can be divided into two types of MV load break switch: FLN36-12D ( K type single spring operating mechanism ), FLRN36-12D (A type double spring operating mechanism). The latter type could be equipped with a fuse combination, having control and protecting functions, which can be used for power supply and substation as a protective and control device, especially suitable for ring main unit, cable distribution box, and switching substation.

Structural features of SF6 load break switch

Basic functions and features

1. Load breaker switch adapts a double fracture, rotary movable contact structure, with the following three kinds of operating states: Closing, opening, and earthing.

2. Using SF6 gas as an arc extinguishing and insulating medium, the main circuit seals are made by the upper and lower housing pouring epoxy resin, and the conductive function is unaffected by external influences.

3. Good safety performance. If internal arcing occurs, the housing has an internal structure weak point. It will be rushed to open, followed by the cabinet above the shutter release ar,c red open air overpressure stream-oriented outside the cabinet, ensuring that the switch cabinet security checks.

4. Load breaker switch sets gates, opening, grounding switch three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock, compact structure, high security, and reliability.

5. Small size, light weight, maintenance-free, easy and safe to operate.

Normal working Environment

1. Altitude: ≤1000m

2. Ambient temperature at -30ºC to +40ºC, the daily average temperature should not more than 30ºC.

3. The daily average of relative humidity is less than 95%, and the average monthly is less than 90%.

4. Working environment should be without steam, gas, chemical corrosive deposition, salt fog, dust, dirt, and other dangerous explosive media, which will severely impact on insulation and conductivity of products.

5. The working environment should not be regular vibration or serious bumps.

PS: Products with special requirements, specifications, and dimensions that need to be improved can be designed and manufactured according to user requirements.
