Gasi Insulated Switchgear GRM6-24

GRM6-24 yakatevedzana SF6 gasi insulated simbi yakavharirwa switchgear (inozozivikanwa segasi insulated switchgear ) inokodzera matatu-phase AC 50Hz, rated voltage 24kV simba rekugovera system, yekupwanya nekuvhara mutoro ikozvino, kuremedza ikozvino, kuvhara nekuvhara pfupi pfupi. Bvisa capacitive mitoro yakadai se-no-load transformers, mitsara yepamusoro, tambo dzetambo uye mabhangi e-capacitor pane imwe nzvimbo, uye kutamba basa rekugovera simba, kutonga nekudzivirira mumagetsi emagetsi. GRM6-24 inotora chimiro chakavharirwa zvizere, miviri yekutanga yakavharirwa inonamirwa mukamuri yemhepo yakashongedzwa nemahwendefa esimbi isina tsvina, uye mwero wekudzivirira unosvika IP67. Iyo yakawanda-yedunhu mhete network switchgear ine yakachengeteka kushanda uye yakakwirira kuvimbika iyo inogona kuenderana neyakaomarara mamiriro ezvakatipoteredza akadai semvura uye munyu mhute, semafashama uye kusvibiswa kwakanyanya. Inoshandiswa zvakanyanya mumapaki emaindasitiri, migwagwa, nhandare dzendege, dzimba dzekugara, nzvimbo dzekutengesa dzakabatikana, nezvimwe. Icho chinhu chakanakira kugovera network otomatiki. Inoshandiswawo mu: compact box-type substations, cable branch box, switchgear, wind power stations, subway uye tunnel lights.

Shandisa Condition

• Ambient tembiricha: -40 ℃~+40℃ (pazasi -30 ℃ inofanira kutaurirana nemushandisi uye mugadziri);

• Altitude:

• Kudengenyeka kwepasi: kwete kupfuura 8 degrees;

• Maximum avhareji yehukama humidity: 24h yevhareji

• Nzvimbo dzisina moto, kuputika, ngura yemakemikari uye kugara uchizunguzika kunotyisa.

Structural Feature

• Yakanyatsovharwa uye yakanyatsogadziriswa yakagadzirwa: Zvose zvipenyu zvikamu zveGRM6-24 zvakavharwa mubhokisi rakashongedzwa ne304 stainless steel plate, bhokisi rakazadzwa neSF6 gasi nekushanda kwekushanda kwe1.4bar, uye chiyero chekudzivirira chiri IP67. Inokodzera kuiswa munzvimbo dzine humidity yakakwirira uye kusvibiswa kweguruva, kunyanya yakakodzera kumigodhi, bhokisi-mhando substations uye chero nzvimbo dzinowanzoita pamusoro pe flashover nekuda kwekusvibiswa kwemhepo. Chigadzirwa chacho chakaiswa neDIN47636 yakajairwa sleeve, uye yakabatana netambo kuburikidza neyakavharirwa yakazara, yakavharwa, yakavharirwa tambo yekubatanidza.

• Kuvimbika kwepamusoro uye kuchengetedzwa kwevanhu: zvikamu zvose zvipenyu zvakavharwa muSF6 air chamber; kamuri yemhepo ine yakavimbika kudzvinyirira chiteshi chiteshi, iyo yakapfuura 20kA / 0.5s yemukati kukanganisa arc bvunzo: iyo inotakura switch uye grounding switch ndeye matatu-nzvimbo switch, iyo inorerutsa kupindirana pakati pavo. Pane yakavimbika mechanicha yekubatanidza pakati petambo compartment chivharo uye yekuremedza switch, iyo inogona kunyatso kudzivirira kupinda mukati menguva nekukanganisa.

• Kuchengetedza-pasina uye kutenderera kwehupenyu hurefu Chigadzirwa chakagadzirwa nehupenyu hwemakore makumi matatu. Munguva yehupenyu hwechigadzirwa, shanduko huru haidi kugadzirisa. The gore negore leakage rate yechigadzirwa ndeye

• Compact structure: Kunze kweair-insulated metering cabinet uye PT cabinet, ose mamodules ane 350mm chete yakafara, uye cable connection bushings yezvikamu zvose zvine urefu hwakafanana kusvika pasi, izvo zviri nyore pakuvaka panzvimbo.

• GRM6-24 inogona kugadzirwa nemichina yekutonga yakangwara (inosarudzika), ichipa kudzivirira kunoshanda, kudzora kure uye kutarisa masisitimu, uye kutsigira otomatiki emagetsi ekugovera masisitimu.

• GRM6-24 inopa nzira mbiri dzekudzivirira kune transformers: load switch fuse musanganiswa uye circuit breaker ine relay kuchengetedza. Load switch fuse musanganiswa midziyo inoshandiswa kune matransformer e1600kVA uye pazasi, ukuwo macircuit breaker ane relay anogona kushandiswa kuchengetedzwa kwetransformer yemhando dzakasiyana.

• Kuchengetedzwa kwezvakatipoteredza: Kuvandudzwa kweGRM6-24 kunosanganisira kwete chete chigadzirwa pachayo, asiwo kuchengetedzwa kwezvakatipoteredza kubva pakugadzirwa kwekugadzira kusvika kuhupenyu hwekushanda kwekuchinja. Zvinhu zvose zvinosarudzwa kuti zvive zvakatipoteredza, uye zero-leakage yekuchenesa nzira inogamuchirwa. Chigadzirwa chacho chakavharirwa kwehupenyu hwose, uye 90% kusvika 95% yezvinhu zvinogona kushandiswazve mushure mekupera kwehupenyu hwechigadzirwa.

Main Technical Parameters

Cherechedza:

1) Zvinoenderana neyakayerwa ikozvino ye fuse;

2) Yakaganhurirwa neiyo high voltage fuse.
