The dependence of insulating materials, it is low-carbon, environmentally protective.Fixed non-maintaining structure general assembly scheme, by the big electro-mechanical part of some loads
Part, which is placed in the phase-splitting insulation space 23 of the atmospheric air of sealing, constitutes independent compartment unit.Cable is passed in and out simultaneously using complete exhausted
Edge, hermetically sealed, touch plug-in cable connector, completely cut off influence of the running environment to equipment, there is brilliant environment to adapt to energy
Power, to achieve the purpose that safety and stability, long service life, maintenance are few.
There is also following advantages for the compact air insulation switchgear 100:
Safe and intelligent: using phase-splitting insulation structure, no phase fault explosion danger, the leakage of no SF6 gas cause insulation and
Arc extinguishing reduced capability causes failure of interruption, causes cabinet explosion danger.Using baffle-type mechanical interlocking operational design, prevent accidentally
By operation handle insertion operation hole in the case where operation, meet five anti-requirements, guarantee equipment using safe.Three stations combined floodgate/
Separation/earthing switch structure, state-visibility.Configuration integration intelligent monitoring component controls network, it can be achieved that measurement digitlization
Change, status visualization and information interaction.
Small compact: using phase-splitting insulation technology, can self-healing insulation system and innovation longitudinal design so that switchgear take up an area
Area size is small, only the 1/3 of tradition KYN28 switchgear.Can be mounted against a wall, compact power distribution room is constructed, is built in urban distribution network
If under the overall background for facing an inch of land is an inch of gold, power distribution room occupied area can be greatly decreased, reduce power distribution room comprehensive cost, bring society
It can be obvious with economic benefit.
Long-life is non-maintaining: the framework design of innovation, the non-maintaining overall plan of fixed breaker, except switch
Predetermined operation or movement are outer, and without moveable components, operating status is stablized, and safety factor is high, fully meet grid company
The requirement of right-secondary switchgear long life.
Modularized design, flexible combination: assembled scheme is flexible and changeable, meets the various scheme of electric power of user, can be in factory
Or any direction expanded set cabinet is realized at scene, fully meet various distribution networks matches electricity demanding.
Brilliant ambient adaptability: due to using air insulation seal case, it is suitble to China vast in territory, area differentiation is aobvious
It writes and complicated and diversified distribution running environment.
