Currently, GIS outlet casing tubes majority is Conventional pneumatic formula structure on 66kV~500kV combined electrical apparatuses, and casing is all
It is installed on open air.Its structure is as shown in Figure 1：By conductor 1, air end porcelain bushing shell 2, SF6Gas 3, cylinder 4, supporting rack 5, transition
Conductor 6 is composed.
Such casing and connection type have the following problems：
1, filled with certain pressure SF inside this casing product6Gas, if there is internal SF in operational process6Gas permeation
When situation, SF can be caused6Gas pressure reduces, due to SF6Gas pressure size decides the height of dielectric level, pressure reduction
Product electric insulation level can be caused to decline, operation troubles occur；
2, some extends to outdoor for the switchgear cylinder 4 that is connected with casing, transition conductor 6, and supporting rack 5 is needed to prop up
Support and fixed, relative increase construction and material cost；
3, when environment temperature is reduced to -45 DEG C or less, and SF6(usually switch when gas operating pressure reaches 0.4Mpa or more
Equipment operating pressure is essentially 0.4Mpa~0.5Mpa), it may appear that following two failures：1. being exposed in outdoor cylinder 4
SF6Gas will appear low-temperature liquefaction phenomenon, generally improves temperature in cylinder using auxiliary electrical heater mode, it is existing to eliminate low-temperature liquefaction
As, but cost input can be increased；2. inside pipe casing SF6There is low-temperature liquefaction phenomenon in gas 3, at this time inside pipe casing SF6Gas pressure
Power reduces, and dielectric level declines, extreme influence circuit operational safety；And casing position can not pass through due to being in high potential
Auxiliary electrical heater mode eliminates low-temperature liquefaction phenomenon.Can only be solved by being changed to indoor outlet method, be significantly greatly increased construction at
This.
In conclusion the present invention devises a kind of glue leaching fiber dry-type capacitance type GIS casings through walls.
