All insulation hermetic SF6 filled tank (JNSS)

JNSS solid insulation intelligent ring network cabinet is a kind of intelligent environmental protection type switch, is an important fulcrum of distribution automation system. JNSS is a kind of green environmental protection, no pollution, small volume, safe and reliable and intelligent combined with a new generation of maintenance free products. The single unit width 420MM, deep 750MM, high 1400MM, can be used alone or combined. Is a perfect combination of vacuum technology and insulation technology, in quenching and insulation performance can be completely replaced by SF6 gas, meet theelectrical products of countries advocate reducing exhaust pollutionrequirements. And with the direction of the grounding protection function, can distinguish the regional internal / external grounding fault, and have goodrelation and dispatching center.

The main components and features:

JNSS is mainly composed of three parts, namely the V unit (breaker unit), C(load switch unit) unit, F unit (combined electrical units), each cell can beused alone can also be free to expand, its structure is divided into the control room, operating mechanism and one part. Control room with microcomputer protection (controller), operating mechanism, operating mechanism for thebullet, a part of the APG automatic gel process, the isolating switch and the arc quenching chamber completely sealed in epoxy resin, and has a special joint and busbar.

Interrupter switch: the arcing chamber adopts copper chromium contactmaterials dedicated, R type longitudinal magnetic field contact, and completea row sealing process, the interrupter breaking short circuit current capacity,stability, electrical life, Wen Sheng and insulation level than before the arc chamber (copper contact material, cup-shaped longitudinal magnetic field structure, as well as incomplete a row sealing process) has been significantly improved.

Operating mechanism: the switch with the mechanism and development ofspring operating mechanism, namely, isolating switch, a main switch and aspring operating mechanism as a whole, can be convenient to realizeinterlocking, the agency a few parts, reduce the transmission links,unnecessary high reliability, and can be based on user needs with manual(must be equipped with electric (,) matching) operation.

Second part: switch a part adopts APG automatic gel process, the conductivecircuit is completely sealed in epoxy resin, and split into three phases, thedesign fully consider the use of national standards and relevant requirements of harsh environment, combined with flood control type touch special plug andmicrocomputer protection, realize whole sealing, distribution of all insulation,maintenance free, miniaturization, intelligent requirements.
