Kugwiritsa ntchito magetsi popanda nkhawa, Cejia Electric.

A chosokoneza derandi switch yomwe ingalumikize ndikuchotsa dera. Malinga ndi ntchito zake zosiyanasiyana, imatha kugawidwa m'magulu awiri: zopumira ma air circuit ndi zopumira zachitsulo (GIS) zomwe zimatetezedwa ndi gasi.
Ubwino wa chotseka mawaya: kapangidwe kosavuta, mtengo wotsika, zimatha kusintha kwambiri kapangidwe ka ntchitoyo; mphamvu yayikulu yosweka, mphamvu yayikulu yodzaza, kulumikizana kosachitika kawirikawiri ndi kusweka kwa chingwe; ntchito yoteteza kwathunthu, imatha kudula mawaya mwachangu nthawi yochepa kwambiri.
Zoyipa za ma circuit breaker: kutentha kwakukulu ndi kuwala kwa arc komwe kumapangidwa nthawi ya short circuit; ntchito zambiri sizingachitike; nthawi yokwanira imafunika kuti chitsulo chomwe chili mu fuse chibwerere pamalo osungunuka.
Pamenechosokoneza deraikasinthidwa kuchoka pa chosinthira mpweya kupita ku GIS, malamulo otsatirawa ayenera kutsatiridwa:
1) Chotsekera mawaya chiyenera kukhala chokhazikika bwino panthawi yoyika ndi kugwiritsa ntchito;
2) Kuteteza bwino kuyenera kusungidwa pakati pa switchgear ya GIS ndi pansi;
3) Malo oyikapo ayenera kukhala ndi malo abwino otulutsira madzi.
Ntchito
A chosokoneza derandi switch yomwe imagwiritsidwa ntchito kuyatsa ndi kuzimitsa dera, ndipo nthawi zambiri imakhala ndi ntchito yoyatsa ndi kuzimitsa dera, komanso imakhala ndi ntchito monga kuteteza dera lalifupi komanso kuteteza kupitirira muyeso. Nthawi yomweyo, mphamvu yake yosweka ndi yamphamvu kwambiri, ndipo imatha kudula dera mwachangu nthawi yochepa kwambiri.
1. Monga chipangizo chogawa mphamvu yamagetsi otsika, chotsegula ma circuit chili ndi ntchito yoteteza ma circuit ku overload, short circuit ndi undervoltage.
2. Chotsekereza magetsi chili ndi ubwino woti chimatha kuletsa magetsi komanso kuchitapo kanthu mwachangu; chilinso ndi ntchito yoteteza magetsi afupiafupi amagetsi afupiafupi amagetsi omwe amasweka nthawi imodzi.
3. Monga chipangizo chogawa mphamvu yamagetsi otsika, chotsegula ma circuit chingathe kutseka kapena kuchotsa ma circuit a magetsi ogwiritsidwa ntchito nthawi zonse mkati mwa nthawi yomwe yaperekedwa; chingathe kupereka mphamvu nthawi zonse ku chingwe popanda kulephera, komanso chingagwiritsidwe ntchito ngati chotenthetsera mota stator ndi ma circuit ngati pakufunika kutero. Ma circuit othandizira a zida zosiyanasiyana zamagetsi.
Ikani
1. Musanayike, yang'anani mawonekedwe a chodulira cha dera kuti muwone ngati pali ming'alu, kenako tsegulani chivundikiro cha kumapeto kwa chodulira cha dera, ndikuyang'ana chizindikiritso ndi dzina la chivundikiro cha kumapeto. Yang'anani motsatira chitsanzo chomwe chafotokozedwa m'buku la malangizo azinthu.
2. Kukhazikitsa kwa chotsegula magetsi kuyenera kukwaniritsa zofunikira pa kapangidwe kake, ndipo kuyenera kugwirizana ndi malo oyika zida zina zamagetsi pa bolodi logawa magetsi kapena chipangizo chogawa magetsi. Sikololedwa kuyika kapena kudutsa pafupi ndi zida zina zamagetsi ndi zida zina (maswichi).
3. Chotsekera mawaya ndi zowonjezera zake ziyenera kukhazikika bwino. Pa mawaya okhala ndi zigawo zambiri, soketi yapamwamba ndi gawo loteteza chingwe ziyeneranso kukhazikika.
4. Njira yogwiritsira ntchito iyenera kuyesedwa katundu musanayichotse kuti zitsimikizire kuti ikugwira ntchito mosinthasintha komanso modalirika musanayichotse. Yang'anani ngati mawaya ali olondola musanayichotse, apo ayi singachotsedwe mwachisawawa.
5. Pamene chotsegula magiya chaikidwa m'bokosi lachitsulo, mabotolo omangirira m'bokosilo saloledwa kumasuka; kulumikizana pakati pa mabotolo omangira bokosi ndi ulusi kuyenera kukhala kodalirika; mtedza womangira uyenera kukhala zomangira zoletsa kumasula; mabowo a zomangira ayenera kubooledwa ndi makina;
Tetezani
Dongosolo likalephera, monga kudzaza injini, kufupika kwa magetsi, ndi zina zotero, ngozi zazikulu ndi zotsatirapo zoopsa zitha kupewedwa, zomwe zimafuna kugwiritsa ntchito ma circuit breaker kuteteza zida zamagetsi kapena ma circuit kuti zisawonongeke. Komabe, circuit breaker singathe "kukonza" popanda kuwonongeka. Nthawi zina, kukonza kwina kumafunikirabe.
1. Ngati magetsi akuyenda mopitirira muyeso panthawi yogwira ntchito ya chopalira magetsi, yang'anani ngati zipangizo zina zamagetsi zili bwino;
2. Yang'anani momwe chipangizo choteteza kutayikira kwa madzi chikugwirira ntchito, ndipo chiyenera kugwira ntchito bwino;
3. Pamene makina ogwiritsira ntchito magetsi alephera, yang'anani mgwirizano pakati pa makina ogwiritsira ntchito magetsi ndi chosokoneza ma circuit;
4. Ngati vuto la short-circuit lachitika mu chingwe, magetsi ayenera kuchotsedwa;
5. Chifukwa cha kukalamba kwa kutentha kwa mkati mwa chotseka ma circuit pambuyo pa kugwira ntchito kwa nthawi yayitali. Chifukwa chake, chotseka ma circuit chiyenera kusamalidwa nthawi zonse.
Kusamalitsa
1. Njira yogwirira ntchito iyenera kukhala yodalirika kuti ipewe ngozi. Payenera kukhala zizindikiro zomveka bwino komanso zochita za gawo lililonse mu njirayo, ndipo zolakwika ziyenera kupewedwa.
2. Ngati chosokoneza mawaya chikugwira ntchito, ngakhale chogwirira chake chili m'malo opunthwa, kugwedezeka kungachitikebe m'malo olumikizirana kapena m'malo otsegulira ndi otseka. Muyenera kusamala kuti musagwiritse ntchito molakwika panthawi yogwira ntchito.
3. Pamene chotsegula magetsi chikugwira ntchito (makamaka podula mphamvu yayikulu), sichingakokedwe mwamphamvu, kuti chisawononge zida zamagetsi.
4. Chotsekera mawaya chiyenera kuyang'ana nthawi zonse momwe chimatsegulidwira ndi kutsekera kuti chipewe kuwononga mphamvu zamagetsi kapena kulephera kwa mphamvu zamagetsi.
5. Ngati vuto lachitika, yesani kubwezeretsa magetsi omwe adadulidwa kaye.
