GIS(GAS INSULATED SWITCHGEAR) be the abbreviation of gas-insulating and fully-enclosed combined electrical apparatus.It is comprised of circuit breaker, isolating switch, earthed switch, mutual inductor, lightning arrester, bus, link and outlet terminal etc., and these parts all are enclosed in the shell of metal ground connection, and section is filled with the SF of certain pressure within it
6Insulating gas, also claim SF
6Fully closed combined electric unit.
GIS equipment since 20th century, the sixties was practical, has extensively run on all over the world.The GIS compact structure, floor space is little, reliability is high, high safety, extensively moves high pressure, ultrahigh pressure, extra-high voltage field; But also there is SF in GIS
6The problems such as Leakage Gas, the infiltration of outside moisture, insulation ag(e)ing, these problems all can cause the GIS internal fault.Need to extract out and be filled with SF before and after the GIS troubleshooting
6Gas, and extract and be filled with SF
6The gas time is sometimes longer than the repair time, has a strong impact on resident living power utility.
Extract at present and be filled with SF
6The SF of gas
6Recovering device, vacuum pump, vacuum measuring instrument, SF
6Storage device directly is connected with GIS by common pipe, is taking out SF
6Gas → vacuumizing → survey degree of vacuum → fill SF
6The device that needs frequent switching to connect in the process of gas, waste a large amount of time; In addition, because working procedure is very high to the requirement of sealing, each COMM communication all needs to re-start good sealing, further increased the time of COMM communication, and the probability of poor sealing is high.
The model utility content
In view of this, the utility model provides a kind of good seal performance, efficiently GIS SF
6System is extracted and be filled with to gas out.
The utility model discloses a kind of GIS SF
6Gas is extracted out and is filled with system, comprises SF
6Recovering device, vacuum pump, SF
6Storage device, vacuum measuring instrument and connecting tube, described connecting tube are the composite tubes with four intercommunication pipelines, and any pipeline of described composite tube all can be opened separately or close, wherein three pipelines of this composite tube respectively with GIS body, SF
6Recovering device is connected with vacuum pump, another root pipeline successively respectively with vacuum measuring instrument and SF
6Storage device is connected.
Further, the port of described pipeline arranges the mobilizable joint that has respectively with the device that is connected, to be complementary.
Further, the port of described joint and pipeline is threaded connection, and is added with the pressure-resistant seal packing ring between this joint and pipe end.
Further, described composite tube and joint are stainless steel, and described pressure-resistant seal circle is the red copper pad.
The beneficial effects of the utility model are: the utility model has designed a kind of novel GIS SF
6System is extracted and be filled with to gas out, this system is taken into account the GIS equipment connection to recovering device, vacuum pump, gas cylinder, vacuum together simultaneously, the switch that only needs to open and close corresponding pipeline just can be realized the switching of equipment, thereby has significantly saved the time of switching device; And the utility model pipe end being provided with can be movable jointing, can, according to because equipment is different, changing corresponding joint, guarantee the versatility of native system; In addition, the utility model pipeline and jointing have good interior pressure tolerance; Finally, the utility model with once bleed and gas replenishment process in only need once sealing, improved the sealing reliability, saved the sealing time.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described;
Fig. 1 is the utility model GIS SF
6System schematic is extracted and be filled with to gas out.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
GIS SF of the present utility model
6Gas is extracted out and is filled with system as shown in Figure 1: comprise SF
6Recovering device 2, vacuum pump 3, SF
6Storage device 4, vacuum measuring instrument (vacuum measuring instrument and SF
6Storage device successively is positioned at 4 position in chronological order) and connecting tube 5, described connecting tube 5 is the composite tubes with four intercommunication pipelines 6, on any pipeline 6 of described composite tube 5, a switch 7 is arranged, all can open separately or close, wherein three pipelines of this composite tube 5 respectively with GIS body 1, SF
6Recovering device 2 is connected with vacuum pump 3, another root pipeline successively respectively with vacuum measuring instrument and SF
6Storage device 4 is connected; In addition, the port of connecting tube 5 is respectively arranged with a mobilizable joint 8 that is complementary with the institute connection set; Further, described joint 8 is threaded connection with the port of connecting tube 5, is added with the pressure-resistant seal circle between this joint and pipe end; Especially, described composite tube and joint are stainless steel, and described pressure-resistant seal circle is the red copper pad.
SF of the present utility model
6Gas is extracted out and is filled with system and can carry out according to following steps in use: at first selected suitable joint before maintenance GIS, and assemble SF of the present utility model
6System is extracted and be filled with to gas out; Then open and GIS body and SF
6Switch on the pipeline that recovering device is connected also cuts out other switches, thereby extracts the SF in the GIS body out
6Gas; Then after maintenance GIS, be filled with SF
6Before gas, the GIS body is vacuumized, this process only need to be opened the switch on the pipeline that is connected with vacuum pump and be closed and SF
