Summary

Cubicle type Gas Insulated Switchgear(CGIS) ndeyemukati, fekitori-yakaungana, simbi-yakavharirwa, cubicle type gasi-insulated switchgear yeimwe busbar application, kusanganisira "Green Type" GPN2E-40.5, GPN2N-40.5 uye "Standard Type" GPN2S-- 40.5.
Iyo "Green type" GPN2N-40.5 inogadzirwa kuti ishandise yakachena nitrogen segasi rekudzivirira kune yakatevedzana chigadzirwa neNon-SF6 gasi insulation tekinoroji, iyo yakaunza chaiyo girinhi kuchengetedzwa kwezvakatipoteredza kwegasi insulated switchgear.
Iyo "Green type" GPN2E-40.5 inobatanidza teknolojia yepamusoro yekavhenganiswa gasi-insulated (SF6 + N2) uye vacuum breakers, zvichiita kuti michina ishande nenzira yakavimbika uye yakasununguka.
Iyo "Standard type" GPN2S-40.5 ndeye 100% SF6 insulated, yakakwirira kushanda uye nyore kushandisa.
Nekugadzirwa kwemazuva ano kwedhijitari uye otomatiki kuyedzwa pamwe chete nesensor, yekutarisa uye yekudzivirira tekinoroji, CGIS yakanakira kugovera magetsi zvinodiwa.CGIS inonyanya kukodzera maindasitiri ane kuvimbika kwakanyanya senge Power Networks, Mining, Rail Transportation, Petrochemical Plants, Wind Farms uye Metropolitan Rail Systems.
Mamiriro ekushanda akajairika
Iyo switchgear yakanyatso gadzirwa kune yakajairika sevhisi mamiriro emukati switchgear kusvika GB 3906, DL/T404 uye IEC 62271-200.Izvo zvinotevera zvinogumira kukosha, pakati pezvimwe, zvinoshanda:
Ambient air tembiricha
Maximum tembiricha yemhepo: +45 ℃
Minimum tembiricha yemhepo: -25 ℃
Zuva nezuva avhareji yepamusoro tembiricha: +35 ℃
Humidity:
Avhareji yezuva nezuva kukosha kwehunyoro hunoenderana: ≤ 95%
Mwedzi wega wega kukosha kwehunyoro hunoenderana: ≤ 90%
Zuva nezuva avhareji kukosha kwehutsi hwemvura kumanikidzwa: ≤ 2.2 × 10-3MPa
Mwedzi wega wega kukosha kwehutsi hwemvura: ≤ 1.8 × 10-3MPa
Kureba: ≤ 1000m
Iyo ambient mweya haina kusvibiswa zvakanyanya neguruva, utsi,
zvinoparadza uye/kana magasi anopfuta, mhute kana munyu.

Special service conditions
Chigadzirwa chacho chinogona zvakare kuiswa kune akawanda akakosha sevhisi mamiriro.
Kana mamiriro esevhisi akadarika zvakajairwa sevhisi mamiriro, ari kunze kweiyo standard GB 11022 uye IEC 62271-1, ndapota bvunzana naGP pachine nguva kuti usimbiswe:
Altitude yakakwirira kupfuura 1000m.
Kupisa kwepamusoro kwezvakatipoteredza.
Kuderera kwekushisa kwezvakatipoteredza.
Mamwe akakosha mamiriro ekunze.

Deredza kubudiswa kwegreenhouse gasi
CGIS inosanganisa matekinoroji epamusoro eNitrogen yakachena kana gasi-yakasanganiswa (SF6 + N2) uye vacuum breakers, sarudzo yakakosha yakaitwa naGP kubatsira mukuderedza greenhouse effect.SF6 (sulphur-hexauoride) iri parunyoro rwemagasi egreenhouse muKyoto Protocol, ine Global Warming Potential (GWP) ye23,000.Mamwe akawanda epakati voltage switchgear masisitimu anoshandisa SF6 gasi seyo chete inodzivirira svikiro.Kudonha kweSF6 gasi kubva ku switchgear kunobatsira mukutyisidzirwa kwegreenhouse effect uye kunoenderana nekushanduka kwemamiriro ekunze.
Nekuzvipira kwedu kuchengetedza nharaunda, CGIS inobatsira kudzikisa kuburitswa kwegasi rinopisa nekushandisa yakasanganiswa gasi-yakavharidzirwa tekinoroji pamwe chete nevevacuum switching tekinoroji.
Kuderedzwa kwe100% kana 50% muSF6 kunowanikwa nekushandisa Nitrogen (N2) yakasanganiswa gasi-insulated breakers.Nitrogen ndicho chikamu chikuru chemhepo uye chigadzirwa chayo chekuora hachina chepfu.Yakabatanidzwa pamwe chete ne-plug-in majoini uye modular hunhu hwemapanera hunova nechokwadi chekumisikidza uye kuwedzera pasina kudiwa kwekuwedzera gasi kubata mabasa pa-saiti.

Advantage

● 70% Kuderedza MuSwitchroom Size
Iyo yakagadziridzwa yemagetsi munda dhizaini yakasanganiswa neakanakisa insulating kuita, inoguma mune compact switchgear chigadzirwa chinoshanda zvakachengeteka uye nekuvimbika.
Sevha 70% nzvimbo uchienzaniswa nemhepo-insulated switchgear.
Kudzoreredza mune iripo switchroom iri nyore.
Deredza mutengo wenzvimbo yechiteshi.
●Kuchengetedzwa Kwepamusoro Kwemushandisi uye Zvishandiso
Iyo shoma inoshanda yekumanikidza ye cubicle ndeye 0.00MPa (20 ℃).Izvi zvinoreva kuti, kunyangwe pasi pemamiriro akanyanya kudaro, inoramba ichichengetedza yakatemerwa insulation level uye inochengeta mashandiro ayo ese akayerwa.Kutenda kune yakaderera kudzvanywa kwegasi, kunyangwe gasi riri kupukunyuka kubva kune switchgear, iyo cubicle inogona kuramba ichisimbiswa.Kuvimbika kwemagetsi uye ma mechanical interlocks akagadzirwa pakati pedunhu rinoputika uye matatu-chinzvimbo switch kudzivirira misoperation.
● Easy Installation/Low Operation Uye Maintenance Cost
Mapaneru ari pakati anogona kubviswa nyore nyore kugadzirisa pasina kufambisa mapaneru evavakidzani, kuwedzera kuwanikwa.
