Solid insulation intelligent ring network cabinet (JNFL)

JNFL full insulation sealed common box type ring network switch device(referred to as the filling cabinet JNFL) is a new generation of miniaturizedmodular switching equipment. The 6 insulating air box in the same SF6 canconfigure common bus (regardless of the incoming and outgoing) unit, each unit has its own function. When asked to configure the number of more than 6units, to the extended bus bar will be in the form of two (or more than two)connect the gas tank. Each SF6 insulating gas tank can be extended on the left and the right side is arranged according to different design schemes of arbitrary, arbitrary, realize the different configuration requirements.

Type JNFL pneumatic gas cabinet of imported stainless steel plate, cuttingand automatic robot welding technology and manufactured using advancedlaser, protection grade reaches IP67 inflatable casing. Box filled with SF6 gas,and through the synchronous vacuum, helium leak detection, to ensure the sealing performance of air box. Load switch, grounding switch, fuse insulating cylinder, vacuum interrupter are sealed in a stainless steel gas tank. Gas at the bottom of the box is arranged on the mouth of the explosion-proofexplosion-proof membrane, when the switch to the abnormal pressure gastank exceeds a certain value, can from the lower explosion proof pressure relief, effectively prevent the damage of high-pressure gas, cable andtransformer substation of the switching equipment.

Type JNFL pneumatic cabinet has the advantages of compact structure, fully closed, fully insulated, long service life, maintenance free, small occupied space, safe and reliable, is not influenced by the working environment and so on, are widely used in industrial and civil cable ring network and terminal power supply. Especially suitable for small two distribution station, open and close,industrial and mining enterprises, airport, railway, commercial areas, high-rise buildings, highways,
