5 zvikamu zveyuniti mhando SF6 mhete main unit:

1. chinja cubicle switch-disconnector uye earthing switch mune yakavharirwa yakazara neSF6 uye inogutsa.“sealed pressure system ” zvinodiwa.

2. bus-bar cubicle yese mundege yakachinjika imwe chete, zvichigonesa gare gare switchboard extensions nekubatanidza kumidziyo iripo.

3. cubicle yekubatanidza inosvikika nekumberi, kubatanidza kune yezasi switch- disconnector uye earthing switch terminals (IM cubicles) kana ezasi ma fuse- holders (PM neQM cubicles). Iri kamuri rakashongedzerwa zvakare ne

earthing switch yakadzika kubva kuMV fuse yezvidziviriro zvikamu.

4. mashandiro ekushandisa, kupindirana kune zvinhu zvinoshandiswa kushandisa switchdisconnector uye earthing switch uye actuate inoenderana.

zviratidzo (positive break).

5. Low voltage cubicle (yepamusoro & yakaderera enclosure chimiro) kuiswa kwe

terminal block (kana mota sarudzo yakaiswa), LV fuse uye compact relay zvishandiso. Kana imwe nzvimbo ichidikanwa, imwe yakavharirwa inogona kuwedzerwa pamusoro pe

cubicle.

6. Optional switch cubicles (IM) inogonawo kuiswa ne: control motorization;

masurge arrestors.

Iyo yechitatu-phase rotary contact inoiswa mukamuri yegasi yakazadzwa neSF6 gasi uye hukama huripo ndeye 0.4bars. Iyo ine yakanakisa mashandiro ekuita nekuchengetedza uye kuvimbika.

● Kusimba:

Imba yemhepo yakazadzwa neSF6 gasi, iyo inosangana nezvinodiwa zve "yakavharwa pressure system", uye yekuisa chisimbiso yakatariswa uye

inoongororwa mufekitari.

● Kuchengetedza Kwekuita:

1. Switch ine zvinzvimbo zvitatu zve "yakavharwa", "yakavhurika" uye "yakadzika", uye ine

kuvhara basa kudzivirira kushanda netsaona. Kubata kunofambiswa kutenderera ne

the spring energy storage mechanism, iyo isingakanganisi nemaitiro ekushanda kwevanhu.

2. Ane "break" uye kuzviparadzanisa mabasa.

3. Iyo pfupi-yedunhu kugadzira kugona kweSF6 grounding switch inosangana nezvinodiwa zvakajairwa.

4. Muchiitiko chetsaona, kudzvinyirirwa kunodonha mushure mokunge SF6 yakanyanyisa gasi inoputika kuburikidza nekudzivirira diaphragm, uye gasi rinozoputirwa zvakananga kumashure kwekabhiniti kuitira kuchengeteka.

Breaking Principle:

SF6 gasi ine yakanakisa arc kudzimisa kuita. Kana iyo switch yakavhurwa, hukama hwekufamba pakati pearc uye gasi hunodzima arc. Kana iyo inofamba uye inomira inobatana yakapatsanurwa, iyo arc inoonekwa mumunda wemagetsi unogadzirwa neanogara magineti, uye iyo arc ndeye.

yakareba uye yakadzimwa kana yazvino ichiyambuka zero neSF6 gasi. Nharaunda pakati pekufamba uye static contacts inokwana kumira kupora overvoltage. Iyo sisitimu iri nyore uye yakavimbika, ine kushoma kwekubata kupfeka uye hupenyu hurefu hwemagetsi.

● Chiratidzo chechimiro cheSwitchgear:

Yakarongedzerwa yakananga kudhiraivha shaft, idzi dzinopa chiratidzo chechokwadi cheiyo nzvimbo yekusangana. (wedzero A yechiyero IEC 62271-102).

● Chibatiso chekushanda:

Izvi zvakagadzirirwa ne-anti-refl ex mudziyo unomisa chero kuedza kuvhurazve mudziyo pakarepo mushure mekuvhara switch kana yekubvisa pasi.

● Chishandiso chekukiya:

Pakati peimwe nenhatu padlock inoita kuti zvinotevera zvivharwe:

● kupinda kune shaft yekushandura yekushandura kana kuputika kwedunhu

● kupinda kune shaft yekushandura yepasi rekubatanidza

● kushanda kwekuvhura kusunungurwa push-button. ●Kuchinja kuri nyore uye kusingashande

Mechanical uye magetsi ekutonga ari padivi nepadivi pane yekumberi fascia, pane panhi

kusanganisira dhiyabhorosi inoratidza chimiro chechishandiso (chakavharwa, chakavhurika, chakaiswa pasi):

● Yakavharwa:

dhiraivha shaft inoshandiswa kuburikidza nekukurumidza kuita maitiro, yakazvimirira yemushandisi. Hapana simba rinochengetwa muchinja, kunze kwekunge uchichinja

maoparesheni ari kuitika.

Kune akasanganiswa switch fuse, iyo yekuvhura michina yakashongedzerwa panguva imwe chete iyo maconta akavharwa.

● Kuvhura:

switch inovhurwa uchishandisa imwechete inokurumidza kuita meshini, inoshandiswa kune yakatarisana.

Kune yakasanganiswa switch fuse unit, kuvhura kunodzorwa ne:

● push-bhatani

● mhosva.

● Earthing:

a specifi c control shaft inogonesa kuvhura kana kuvharika kweanobatika pasi. Kupinda kune iyi shaft yakavharwa nekavha inogona kutsvedza kumashure kana switch iri

rakavhurika asi rinoramba rakakiiwa panzvimbo kana rakavharwa.

Voltage kuvapo chiratidzo

Ichi chishandiso chakabatanidza VPIS (Voltage Presence Indicating System) marambi emhando, inoenderana neIEC standard 61958, ichigonesa kuvepo (kana kusavapo) kwevoltage kutariswa patambo.

Kusanzwa kune zvakatipoteredza

● Chivharo chemukati chakavharwa, chine zvikamu zvinoshanda zveLBSkit

(switch, earthing disconnector). Iyo yakazadzwa neSF6 zvinoenderana netsanangudzo muIEC kurudziro 62271-200 ye "yakavharwa kumanikidza.

masisitimu".

Kuisa chisimbiso kunotariswa zvakarongeka mufekitari.

● Zvikamu zvakagadzirirwa kuti zviwane zvakakwana magetsi fi eld kugovera.
