Chiyambi Chachidule cha Switchgear

Switchgear ndi mtundu wa zida zamagetsi, kunja kwa switchgear kumalowa kaye mu switch yayikulu yowongolera mu kabati, kenako kumalowa mu switch ya sub-control, ndipo sub-circuit iliyonse imayikidwa malinga ndi zosowa zake.
Monga chida, chowongolera chokha, chosinthira maginito cha mota, mitundu yonse ya ma contactor a AC, zina zimayikidwanso chipinda chopanikizika kwambiri ndi kabati yosinthira chipinda chopanikizika chochepa, yokhala ndi basi yopanikizika kwambiri, monga malo opangira magetsi, zina zimayikidwanso kuti ziteteze zida zazikulu kuti zisachepetse katundu wambiri mlungu uliwonse.
Ntchito yaikulu ya kabati yosinthira magetsi ndikutsegula ndi kutseka, kuwongolera ndi kuteteza zida zamagetsi popanga magetsi, kutumiza, kugawa ndi kusintha mphamvu zamagetsi.
Zigawo zomwe zili mu kabati ya switch makamaka zimaphatikizapo chotsegula ma circuit, chosinthira cholumikizira, chosinthira katundu, njira yogwiritsira ntchito, chosinthira cholumikizirana ndi zida zosiyanasiyana zotetezera.
Pali njira zambiri zogawa ma switchgear, monga momwe chosinthira ma circuit breaker chimagawidwira m'magulu awiri: switchgear yosuntha ndi switchgear yokhazikika;
Kapena malinga ndi kapangidwe kake kosiyana ka kabati, ikhoza kugawidwa m'magulu awiri: kabati yotseguka yosinthira, kabati yotsekedwa ndi zitsulo, ndi kabati yotsekedwa ndi zitsulo yotchingira zida;
Malinga ndi milingo yosiyanasiyana ya magetsi, ma switchgear amatha kugawidwa m'magulu awiri: switchgear yamagetsi okwera, switchgear yamagetsi apakati ndi switchgear yotsika.
Makamaka amagwiritsidwa ntchito pa malo opangira magetsi, malo osungiramo zinthu, petrochemical, zitsulo zozungulira zitsulo, nsalu zopepuka, mafakitale ndi mabizinesi amigodi ndi malo okhala anthu, nyumba zazitali komanso zochitika zina zosiyanasiyana.

A. "Chitetezo Chachisanu" cha Chida Chosinthira Mphamvu Yapamwamba

1. Trolley ya vacuum circuit breaker yomwe ili mu kabati yosinthira magetsi ambiri itatsekedwa pamalo oyesera, trolley circuit breaker singathe kulowa pamalo ogwirira ntchito. (Letsani kutseka ndi katundu)

2. Mpeni wothira pansi mu kabati yosinthira magetsi amphamvu kwambiri ukakhala pamalo ake, chothyola magetsi cha galimoto sichingalowe ndi kutseka. (Letsani waya wothira pansi kuti usatseke)

3. Pamene chotsegula magetsi cha vacuum mu kabati yosinthira magetsi amphamvu chikugwira ntchito potseka, chitseko chakumbuyo cha kabati chimatsekedwa ndi makinawo pa mpeni woyambira. (Kuti tipewe kusokonekera kwa nthawi yamagetsi).

4. Chotsekera magetsi cha vacuum chomwe chili mu kabati yosinthira magetsi ambiri chimatsekedwa ikagwiritsidwa ntchito, ndipo mpeni wothira nthaka sungaikidwe. (Letsani chingwe chothira nthaka kuti chisamapachike pamene chikugwira ntchito)

5. Chotsekera ma vacuum circuit mu kabati yosinthira ma voltage ambiri sichingathe kutuluka pamalo ogwirira ntchito a chotsekera ma circuit cha galimoto chikagwira ntchito. (Pewani kukoka mabuleki ndi katundu)

B. Kugawa
Yagawidwa m'magulu amagetsi

Malinga ndi magulu a magetsi, AC1000V ndi pansi pake nthawi zambiri amatchedwa switchgear yamagetsi otsika (monga PGL, GGD, GCK, GBD, MNS, ndi zina zotero), ndipo AC1000V ndi pamwamba pake amatchedwa switchgear yamagetsi okwera (monga GG-1A, XGN15, KYN48, ndi zina zotero). Nthawi zina magetsi omwe ali mu kabati yamagetsi okwera ndi AC10kV otchedwa kabati yamagetsi apakatikati (monga kabati ya XGN15 10kV ring network).

C. Yogawidwa ndi mafunde amagetsi

Yogawidwa m'magulu awa: Kabati yosinthira ya AC, kabati yosinthira ya DC.

D. Yogawidwa m'magulu malinga ndi kapangidwe ka mkati

Chosinthira chokokera (monga GCS, GCK, MNS, ndi zina zotero), chosinthira chokhazikika (monga GGD, ndi zina zotero)

E. Pogwiritsa ntchito

Kabati yolowera, kabati yotuluka, kabati yoyezera, kabati yolipirira (kabati ya capacitor), kabati ya pakona, kabati ya basi.

Njira zogwirira ntchito
A. Njira Yotumizira Mphamvu

1. Ikani mbale yotsekera kumbuyo kaye, kenako tsekani chitseko chakutsogolo.
2. Gwiritsani ntchito spindle yosinthira pansi ndikutsegula.
3. Kankhirani galimoto yamanja (yomwe ili mu brake yotseguka) mu kabati (malo oyesera) ndi galimoto yosinthira (galimoto ya papulatifomu).
4. Ikani pulagi yachiwiri mu soketi yokhazikika (chizindikiro cha malo oyesera chili choyatsidwa), tsekani chitseko chapakati chakutsogolo.
5. Kankhirani ngolo yonyamula katundu kuchokera pamalo oyesera (monga momwe zilili) kupita pamalo ogwirira ntchito ndi chogwirira (chizindikiro cha malo ogwirira ntchito chili choyatsidwa, chizindikiro cha malo oyesera chili chozimitsidwa).
6. Galimoto yotsekera dera lozungulira.

B. Kulephera kwa magetsi (kukonza) Njira
1 Tsegulani galimoto yoyendetsa mawilo.
Tulukani mgalimoto yogwira ntchito kuchokera pamalo ogwirira ntchito (momwe brake imatseguka) kupita pamalo oyesera ndi chogwirira.
3 (chizindikiro cha malo ogwirira ntchito chazimitsidwa, chizindikiro cha malo oyesera chayatsidwa).
4 Tsegulani chitseko chapakati chakutsogolo.
5 Kokani pulagi yachiwiri kuchokera mu soketi yokhazikika (yesani chizindikiro cha malo).
6. Tulukani m'galimoto yogwiritsidwa ntchito ndi manja (yotseguka) kuchokera m'kabati ndi galimoto yotumizira.
7. Gwiritsani ntchito spindle yosinthira pansi ndikuyipangitsa kukhala yoyandikana.
8. Tsegulani mbale yotsekera kumbuyo ndi chitseko chakutsogolo chakumunsi.

Kuyang'anira ndi kuteteza chitetezo
Kudzera mu mayesero osiyanasiyana owunikira, mawonekedwe a arc yamkati yolakwika amatsimikiziridwa.
Pachifukwa ichi, sensa ya optical fiber ndi chipangizo chodziwika bwino komanso chotetezeka cha multi-point internal arc detection and protection device chimapangidwa pogwiritsa ntchito lamulo la arc single criterion.
Chipangizochi chili ndi ubwino wa kapangidwe kosavuta, mtengo wotsika, nthawi yogwira ntchito mwachangu komanso mphamvu yolimbana ndi kusokoneza.
Sikuti ingagwiritsidwe ntchito yokha, komanso ingaphatikizidwe ndi zida zosiyanasiyana zotetezera ma relay, kuti mtengo wa kabati yosinthira usakwere, mulingo waukadaulo ndi mtengo wowonjezera ziwonjezeke kwambiri.
