Definitions
- the invention relates to a filter bag for receiving of filter material which within an encapsulation of a gas-insulated, at a switch-off one Switching gas jet causing electrical switching device Decomposition products from the switching gas binds.
- Such a filter bag is known for example from the published patent application DE 25 57 298 A1.
- the publication is a three-phase encapsulated gas-insulated circuit breaker removable.
- the pressurized gas used is sulfur hexafluoride (SF 6 ).
- SF 6 sulfur hexafluoride
- the decomposition products formed occur as gaseous and solid substances. With an increase in the concentration of the decomposition products there is a risk that the insulating properties of the compressed gas are adversely affected.
- filters are provided within the enclosure.
- the active filter material is introduced in small filter bags in the interior of the enclosure.
- the filter bag receiving devices are provided in the interior, which consist for example of a metallic hole material in order to achieve a good gas permeability.
- the arrangement of the receiving devices for the filter bag within the enclosure results from the requirements of a sufficient dielectric and thermal dimensioning.
- the receiving devices serve in addition to the inclusion of the filter material bag substantially for the protection of the filter bag before occurring during a switching process hot switching gas or plasma streams.
- the deflector effect of the hole material is necessary to avoid burning the filter bag and thus destroying the filter.
- the formation of the hole material must be made so that despite the protection of the filter sufficient flow is possible.
- the arrangement of the filters is essentially always one Compromise between a position with optimal filter behavior and a favorable electrical arrangement of the electric field affecting recording devices.
- the present invention is based on the object, a Filter such form that within compressed gas spaces electrically encapsulated plants a reduction of metallic Recording devices is achieved.
- the object is with a filter bag of the aforementioned Art according to the invention solved in that the filter bag consists of a high temperature resistant fabric and in the switching gas jet is arranged.
- the fabric is a mixture from amorphous, inorganic and highly crystalline organic Synthetic fibers is.
- Such a fabric has a good gas permeability and thus influences the filter effect of the active filter material only small.
- the long-term temperature resistance of several 100 ° C and the contact temperature resistance over 1000 ° C make favorable characteristics for use within a compressed gas insulated switchgear
- the material is resistant to sparks, Flames and glowing fire.
- such fabric has optimal mechanical properties, in particular a high tensile strength in the longitudinal and transverse directions, creating a good Protection of the filter material against mechanical stress during the introduction into the encapsulation and before during the operation occurring mechanical vibrations guaranteed is.
- Such fabrics are, for example, among the Trade names Systaceram or Kevlar known.
- FIG 1 is a section of a high-voltage circuit breaker in open air design shown schematically. It is an end of an interrupter unit in section shown.
- the compressed gas encapsulation has a porcelain body 1, which on its outer surface with a Ribbing is provided.
- the porcelain body 1 forms a Main gas space 10, which receives an interrupter unit 12.
- At the end of the porcelain body 1 is a mounting flange 2 arranged.
- the mounting flange 2 serves to receive a dome-shaped end fitting 3.
- the dome-shaped end fitting 3 has an opening 4 through a Cover 5 is closed.
- At the dome-shaped end fitting 3 is still a connector 6 for connection provided to an electrical system.
- the dome-shaped end fitting 3 has at its the porcelain body 1 facing Side as a deflection 7 for switching gas flows trained intermediate plate on.
- This deflecting element 7 is used mechanical storage and electrical contact one end of the interrupter unit 12, which inside the Pressure gas encapsulation is arranged.
- a cavity 8 has been formed.
- the main gas room 10 is through a plurality of openings 9a, 9b with the cavity 8 gas permeable connected.
- As insulating and extinguishing gas Sulfur hexafluoride is used.
- a plurality of filter material containing filter bag 11 are arranged. These filter bags 11 are through the opening 4 of the dome-shaped end element 3 can be introduced.
- the filter bag 11 consist of a high temperature resistant fabric. To the Sewing the bag, a high temperature resistant thread is used.
- the filter bag 11 are in direct contact with the walls of the deflecting element 7 and the dome-shaped End fitting 3. As can be seen, additional the heat-reflecting recording devices omitted.
- the switching gas jet generated during a switch-off process flows out of an outlet opening of the interrupter unit 12 against the deflector 7 and becomes a large part diverted. Parts of the switching gas flow flow through directly the openings 9a, 9b in the cavity 8 and flow through the Filter bag 11. Within the pressurized gas encapsulation is the Switched gas jet reflected. The reflected switching gas jet amplifies the flow through the cavity 8 and the therein arranged filter bag 11th
- the decomposition products contained in the switching gas are at the direct flow through the filter bag 11 through the filter material bound.
- the formation of the filter bag 11 A high-temperature-resistant fabric allows direct flow the filter bag 11 with the hot switching gas jet. The filtering effect is over the known arrangements improved.
