Advantages of solid insulated ring network cabinetAddtime：2015/8/27 

  ring network refers to the ring distribution network, that is, the power supply line to form a closed loop, power supply power supply to the circular trunk, from the trunk road, a road through the high-voltage switch to the outside distribution. The advantage is that each power distribution branch can be the same as that of its left trunk, and it can be taken from the right side of the trunk. When the left trunk is out of the fault, it continues to be powered from the right side, and when the right side of the main line out of the fault, it continues to be powered from the left trunk, this way, although the total power is a single way, but from each power distribution branch is similar to the dual power supply, thereby improving the reliability of power supply.    

  called "ring network cabinet" is each power distribution branch set up a switch cabinet (outlet switch cabinet), the switch cabinet of the bus at the same time is a part of the ring. That is to say, the ring is composed of the bus bar of each outlet cabinet. Each outlet cabinet is called "ring network cabinet". In fact, come up with a ring network cabinet can not see the meaning of the ring network.

        ring network cabinet appears not a long time, it has been widely used, which is determined by it has its own advantages, its advantages see details:

      environmental protection: the abolition of six sulfur hexafluoride gas and the corresponding gas box parts of solid insulated switchgear, the insulating sleeve curing switch parts, from the closed bus connecting each loop, the overall realization of full closed insulation, provides technical means for the reduction of six sulfur hexafluoride emissions.    

  safety: solid insulated ring network cabinet will be the vacuum arc extinguishing chamber, the main electric circuit, insulation support and other organic combination as a whole, to achieve full insulation, fully sealed, maintenance free structure. The interphase is completely cut off, and has the explosion-proof performance.    

  Intelligence: can be added to the field of voltage transformer, modular operating mechanism, can be directly implemented in the operation of the manual to electric upgrade, load switch instantaneous break, truly meet the requirements of distribution network automation.   flexible: solid insulation ring network cabinet to meet the requirements of IP67 protection level based on the realization of the unit assembly, unit replacement, program exchange, greatly reducing the operating costs, intelligent upgrade, internal monitoring, anti harsh environment (cold, high altitude, strong wind and sand, underground, etc.) have obvious advantages.
