Description
The FLN36-24kV SF6 load break switch is a pivotal component in medium voltage switchgear, leveraging SF6 gas as an arc extinguishing and insulating medium. With three distinct working positions – open, closed, and earth – this switch offers versatility and adaptability to diverse applications, making it a top choice in the industry.
Key Features and Types:
- Compact and Adaptable: Its compact size, ease of installation, and robust environmental adaptability make it suitable for various applications.
- Two Variants: The switch comes in two types: FLN36-24kV (K type single spring operating mechanism) and FLRN36-24kV (A type double spring operating mechanism). The latter can be equipped with a fuse combination, providing control and protection functions, making it ideal for power supply, substations, and as a protective and control device, particularly suitable for ring main units, cable distribution boxes, and switching substations.
Ambient Conditions:
- Temperature: -40℃ to +40℃
- Relative Humidity: Daily average ≤ 95%, Monthly average ≤ 90%
- Altitude: ≤ 2000m
- Earthquake Intensity: ≤ 8 degrees
- Environment: No corrosive gas, no combustible gas, no steam, and minimal vibrations.
Operating Mechanism:
Manual Operating Mechanism:
- K Type Spring Dual-Function Operating Mechanism: This mechanism operates via spring press and release for functions like earthing, switch-on, and switch-off.
- A Type Spring Dual-Function Operating Mechanism: Similar to the K type but with an additional fuse striker trip function. Electromagnetic trip is also available upon request.
Switch On/Off Operation:
- The operation involves rotating crank arms, triggering springs, and driving contactors to either connect or disconnect the load.
Earth Operation: Earthing is seamlessly integrated into the mechanism’s functions.
Motorized Operating Mechanism:
- Motor operation can be added to both operating mechanisms, allowing for manual or motorized operation. It supports various operating voltages, including DC48V and AC/DC 110V 220V.
The FLN36-24kV SF6 load break switch is a reliable and versatile solution for medium voltage switchgear needs. Its adaptability, environmental resilience, and choice of operating mechanisms make it a valuable asset in power distribution systems.
