Munguva pfupi yapfuura, takabudirira kupa mabhurashi ecarbon brush ekugadzira jenareta hombe ye turbine inotonhodzwa ne hydrogen, tichipa mhinduro yakagadzirirwa iyo inovimbisa kushanda kwakavimbika uye kwakasimba kweyuniti yekugadzira magetsi.
MaParameters Epakati eGenerator Inoenderana

Maparamita eMatched Carbon Brushes uye Zvikamu zveBrush Holder
Kuti tienderane nezvinodiwa zvejenareta iyi zvine simba guru, takapa seti yakazara yezvikamu zvemabhurashi ekabhoni uye zvinobata mabhurashi zvine zviyero zvinotevera:
| Zita reZvikamu | Upamhi (mm) | Ukobvu (mm) | Kureba (mm) | Mashoko |
| Bhokisi remabhurashi | 159 | 84 | 143 | - |
| Rutsigiro rwebhurashi | 90 | 32 | 192 | - |
| Bhurashi (NCC-634) | 25.4 | 38.1 | 102 | Kureba kwasara pamuganhu wekupfeka: 45 mm |
Bhurasho rekabhoni (NCC-634) chinhu chakakosha musystem yekuburitsa magetsi. Rakagadzirirwa kuchengetedza kubatana kwemagetsi kwakasimba pasi pekutenderera kwekumhanya kwe3,000 rpm uye simba remagetsi re2,760 A, zvichiita kuti simba remagetsi rekuburitsa magetsi rifambe zvakanaka.
Bhurasho iri rekabhoni rinotsiva zvakananga, rinodonhedzwa neMorgan NCC-634 (rinochinjikawo neMersen LFC554). Rakaedzwa zvakasimba uye rakasimbiswa kuti rinopa simba rakaenzana, uye mune dzimwe nguva, remagetsi ekufambisa, kusanganisira resistivity inoenderana, kudonha kwevoltage yekubata, uye hunhu hwekupfeka. Rinovimbisa kutamiswa kwemagetsi ekufambisa, kunyangwe mumamiriro ezvinhu anoda kumhanya kwakanyanya uye emagetsi epamusoro ejenareta iyi ye245,800 kVA hydrogen-cooled, ichipa imwe nzira inodhura uye inoshanda zvakanyanya yekugadzirisa nekugadzirisa zvivakwa zvemagetsi.
Mashandisirwo eChigadzirwa uye Mabhenefiti Ekushanda
Mabhurashi ekabhoni (NCC-634) anopiwa akagadzirwa zvakanangana nemajenareta makuru eturbine anoshanda munzvimbo dzinoda simba rakawanda. Zvakanakira zvikuru zvinosanganisira:
- Kufambisa Kwemagetsi Kwakanaka Kwazvo: Inoita kuti simba risanyanya kubatwa uye kudonha kwemagetsi, zvichideredza kurasikirwa kwesimba.
- Kuramba Kupfeka Kwakanaka: Inowedzera hupenyu hwebasa uye inoderedza nguva yekugadzirisa, kunyangwe mumamiriro ezvinhu ane simba guru uye kumhanya kwakanyanya.
- Kuramba Kunoshamisa Kwekudzungudza: Inochengetedza kushanda kwakasimba kwekubata, ichidzivirira kupenya kwemoto uye kutadza kushanda zvakanaka panguva yekushanda.
- Kukwana Kwazvo: Zviyero zvacho zvakanyatsoenderana nezvikamu zvepakutanga zvechibatiso chebhurashi, zvichiita kuti chive nechokwadi chekuiswa zvakanaka uye kushanda zvakanaka.
Zvinhu izvi zvakakosha pakushanda kwenguva refu, nemazvo, uye zvakachengeteka kwejenareta inotonhorera hydrogen ye245,800 kVA, iyo inoita basa rakakosha mukugadzira magetsi echigadzirwa chemagetsi.
Mufananidzo Wemuviri weBhurashi reCarbon Rakafananidzwa
Takazvipira kupa zvigadzirwa zvakakosha zvekutsigira indasitiri yemagetsi yepasi rose, zvichibatsira majenareta kuti ashande zvakanaka, zvakagadzikana, uye kwenguva refu. Hunyanzvi hwedu muhunyanzvi hwemabhurashi ecarbon hunovimbisa kuti tinokwanisa kupa mhinduro dzinosangana nezvinodiwa zvakanyanya zvekushanda, kunyangwe pamidziyo yekare yakaita sejenareta iyi yakatonhodzwa nehydrogen ya1984.
