CHENJEZO POGWIRITSA NTCHITO MA TRANSFORMERS OYESEDWA NDI MAFUTA

Malangizo ogwiritsira ntchito ma transformer oyesera oviikidwa mu mafuta ndi awa:

1. Lumikizani dera logwirira ntchito molingana ndi mayeso ofunikira. Chigoba cha chosinthira choyesera choviikidwa mu mafuta ndi chigoba cha bokosi lowongolera (tebulo) ziyenera kukhazikika bwino. Mchira wa X-end (mchira wamagetsi apamwamba) wa chosinthira choyesera choviikidwa mu mafuta ndi F-end ya chosinthira choyezera ziyenera kukhazikika bwino.

2. Pochita mayeso a cascade, terminal ya X ya ma windings achiwiri ndi achitatu otsika mphamvu, terminal ya F ya ma windings oyezera ndi terminal ya X (mchira wamagetsi amphamvu) ya ma windings amphamvu mphamvu zonse zimalumikizidwa ku casing ya test transformer ya siteji iyi. Casing yakunja ya ma test transformers oyezera mafuta a pamlingo wachiwiri ndi wachitatu iyenera kukhazikika pansi kudzera mu insulating support.

3. Musanayatse magetsi, chowongolera magetsi cha bokosi lowongolera magetsi loyezera mafuta (unit) chiyenera kusinthidwa kukhala zero musanayatse magetsi, kutseka switch, ndikuyamba kuwonjezera magetsi.

4. Zungulirani gudumu la chowongolera mofanana kuti muwonjezere kuthamanga kuchokera pa zero. Njira zolimbikitsira ndi izi: njira yolimbikitsira mwachangu, yomwe ndi njira yolimbikitsira pang'onopang'ono ya 20s; njira yolimbikitsira pang'onopang'ono, yomwe ndi njira yolimbikitsira pang'onopang'ono ya 60s; njira yolimbikitsira pang'onopang'ono kwambiri posankha.

Pambuyo poti magetsi akwera kuchoka pa zero kufika pa 75% ya magetsi oyesera omwe mukufuna mwanjira inayake yolimbikitsira ndi liwiro, amakwera kufika pa magetsi oyesedwa omwe mukufuna pa liwiro la 2% ya magetsi oyesera omwe adayesedwa pa sekondi imodzi, ndipo samalani kwambiri ndi muyeso wa zizindikiro za mita ndi momwe chinthu choyesera chilili. Ngati chizindikiro cha chida choyezera ndi momwe chinthu choyesedwacho chilili zapezeka kuti sizachilendo panthawi yopititsa patsogolo transformer yoyesera yomizidwa ndi mafuta kapena panthawi yoyesa, kuthamanga kuyenera kuchepetsedwa nthawi yomweyo, magetsi ayenera kudulidwa, ndipo mkhalidwewo uyenera kuyang'aniridwa.

5. Pambuyo pa mayeso, chowongolera magetsi chiyenera kubwezeretsedwa pamalo a zero pa liwiro losasintha mkati mwa masekondi ochepa, kenako magetsi ayenera kudulidwa.

6. Musapitirire malire omwe adavoteredwa. Kupatula ngati pakufunika kuyesa, musalole kuti mphamvu yamagetsi yonse igwiritsidwe ntchito kapena kuchepetsa mphamvu.

7. Poyesa kuthamanga kwa magazi, kuwonjezera pa kudziwa bwino buku la malangizo a mankhwala, ndikofunikiranso kutsatira mosamala miyezo ya dziko lonse komanso njira zogwirira ntchito. Onani GB311-83 “Kugwirizanitsa kutenthetsa kwa zida zotumizira ndi kusintha kwa magetsi amphamvu, ukadaulo woyesera magetsi amphamvu”; “Njira zoyesera zopewera zida zamagetsi” ndi zina zotero.
