2nd, the switchgear cylinder 4 that is connected with sleeve pipe, transition conductor 6 some extend to outdoor, it is necessary to support frame 5
Supporting and fix, relative increase construction and material cost；
3rd, when environment temperature is reduced to below -45 DEG C, and SF6Gas operating pressure reaches (usual during more than 0.4Mpa
Switchgear operating pressure is essentially 0.4Mpa~0.5Mpa), it may appear that following two failures：1. exposed to outdoor cylinder 4
Interior SF6Low-temperature liquefaction phenomenon occurs in gas, general to improve temperature in cylinder using auxiliary electrical heater mode, eliminates Low Temperature Liquid
Change phenomenon, but cost input can be increased；2. inside pipe casing SF6There is low-temperature liquefaction phenomenon in gas 3, now inside pipe casing SF6Gas
Body pressure reduces, and dielectric level declines, and extreme influence circuit is safe for operation；, can not and sleeve pipe position is due to being in high potential
Low-temperature liquefaction phenomenon is eliminated by auxiliary electrical heater mode.Can only be solved by being changed to indoor outlet method, be significantly greatly increased and built
It is set as this.
In summary, the utility model devises a kind of glue leaching fiber dry-type capacitance type GIS sleeve pipes through walls.
