Model:FKN12-12D
Air Blast Load Break Switch, suitable for 12kV and below three-phase power distribution system, as the control and protection of power equipment such as transformers, cables, overhead lines, etc.; especially suitable for terminal substations of urban power grids and rural power grids and box-type substations. And it is suitable for control and protection of ring network and double radiation power supply unit.
Use environment
1. Ambient temperature -25℃-+40°℃
2.Elevation≤1000m
3.Humidity: daily average humidity≤95%,monthly≤90%
4.The earthquake does not exceed degree 8
5.No fire, explosion, chemical errosion
6. Pollution: level 2
Structural features
1, Load switch, grounding switch, fuse and institutions in a framework that can be flxibly 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 static contact insulation cover, so RMU in the structure to achieve the isolation, eliminating the phase insulating space , 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 properties.
5, Load switch and grounding switch, a reliable mechanical locking device between the fuse, to meet the 'Five Anti' 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.
