Three Phase High Voltage Air-Blast 12KV Gas Insulated Load Break Switch
FKN12A- 12D Series air- blast load break switch and FKRN12A- 12D series air- blast load break switch-fuse combination apparatus are new series switchgear applies to three- phase electric distribution system of rated 12KV, acting as protecting and control apparatus for transformers, cable and overhead wiring. These series are espeially applicable in rural. urban terminal substation and prefabricated substations, as well as ring network power supply.
FKN12A- 12D Series air-blast load break switch can break and make load current and over-current.
FKRN12A- 12D Series air- -blast load break switch can break and make over-current, load current and short-circuit crrent(imited current fuse).
This product is featured with impact structure, aesthetic appearance reliable interlock and high insulating level. In the spring storage operating mechanism. ON/OFF speed is free from the infuence of the manpower. For the arc-extinguish electric arc-extinguish inside the insulating cover. the free gas occurs at sparking do not cause descend of insulating level between phases and phase to earth. The insulating cover clapboard separates electrified part thus boost protection grade of ring main unit. The copper-tungsten contact and main contact brings along relible conductivity and long life. This product achieves sound fame due to easy maintenance and operations as well as reliable performance. It is in compliance with per IEC62271-105.
Structural Features
1. load switch, grounding switch, fuse and instutions in a framework that can be flexibly combined, compact, convenient and easy to install a small volume.
2. the fracture is direct acting arrangement. dynamic and thermal stability current parameters is high, time to complete the operation.
3. with staltic contact insulation cover, so RMU in the structure to achieve the isolation, eliminating the phase insulating spacer, fracture insulation boards that can prevent internal arc short circuit accident.
4. has a unique valve structure, load switch after opening the shutter automatically fracture isolation, good protective properies.
5. load switch and grounding switch, a rliable mechanical locking device between the fuse. to meet the "Five Antir requirements.
Two forms of electric operations 6, with manual operation and AC and DC operating power supply, easy to implement power system, "three remote' requirements.
| Ambient condition | 1. The altitude: under 1000M. 2. The ambient temperature: -25℃-+40℃. 3. The relative humidity of air: monthly≤90%, daily≤95%. 4. Ampitude: Earthquake degree 8. 5. Aplication occasions should free from fire, inflammables, explosives,corrosives and severe vibration. |
