Nigute ushobora gukumira neza ibibazo birenze urugero mugihe cyo gusimbuza

Muburyo bwo gukora transformateur idafite umutwaro, hazabaho ibintu byumubiri bidashobora kwirindwa, ni ukuvuga guhagarikwa.Ikibazo cyo gukora overvoltage bitewe no guca amashanyarazi yamashanyarazi birashobora gukumirwa hafashwe ingamba zikurikira:

1. Kunoza icyuma

Gutezimbere icyuma kigira ingaruka runaka mukugabanya imizigo idafite.Kuberako imiyoboro ya magnetisiyasi hamwe nicyuma cyatakaye hamwe hamwe bigizwe numuyoboro udafite umutwaro, hamwe numuyoboro wa magneti uzabyara ibintu bya magnetiki, kandi gutakaza ibyuma byicyuma bizatera ibyuma bitakaza ibyuma, bityo rero icyuma cya transformateur nikintu cyingenzi kuri gabanya nta-imitwaro ihari.Kurushaho kunoza imiterere yibanze no kuzamura ubwiza bwibyuma ni ingamba ebyiri zifatizo.Ibinyampeke bikonje birashobora gukoreshwa aho gukoresha ibyuma bya silikoni, kubera ko sisitemu ya rukuruzi ya rukuruzi yimbeho ikonje ari ndende.Iyo transformateur imaze kuvugururwa, icyuma kigomba kugenzurwa no kugenzurwa byimazeyo ukurikije ubuziranenge bujyanye.

2. Guhinduranya bifata ubwoko butandukanye

                                                               HV HIPOT GDB-P ihinduranya ibyuma bihindura ibipimo

Impinduka ya 220kV ni impinduka nyamukuru.Niba uburyo bwo guhinduranya buhindagurika, ubushobozi bwa parasitike ya transformateur buziyongera.Kuzunguruka bifatanye ni ugushiramo ubundi buryo bwo guhinduranya bitaziguye hagati yumuriro uhuza amashanyarazi, kugirango ubushobozi bwigihe kirekire bwumuyaga bwiyongere, kandi itandukaniro nyaryo rishobora kuba hagati yimpande zegeranye rizakomeza kwiyongera, kuburyo imbere yibirori ya overvoltage phenomenon, voltage yambere irashobora kugabanwa kuringaniza.

3. Koresha icyerekezo hamwe na parallel irwanya

Mugihe cyo guhagarikwa kwubu, ingufu za magneti zumurima muri inductor zizahindurwa ingufu zamashanyarazi kugirango zishyure capacitor.Muri iki gihe, niba ihinduranya ihujwe na résistoriste, ingufu za magnetique yumurima muri inductor zirashobora kurekurwa.Nyuma yo guhinduranya hamwe na parallel irwanya gufunga mbere yo guhagarikwa, guhinduranya parallel irwanya-bigufi.Nyuma yo guhagarikwa, icyuma gifata umutego wa R84Th N kugirango ugire umuyoboro, kugirango ingufu za magneti zumurima muri inductor zizakoreshwa.
