Chotsekera ma circuit chakunja cha LW8-40.5 SF6 ndi chipangizo chakunja chomwe chimagwiritsidwa ntchito mu AC 50HZ three-phase power system ya 40.5KV, kuti chigwire ntchito ngati gawo loteteza ndi lowongolera zida za gridi ndi zida zamabizinesi amigodi yamafakitale. Chimagwiritsidwa ntchito m'malo omwe amafunika kugwira ntchito pafupipafupi mu current yoyesedwa kapena yotsika mobwerezabwereza pa current yaifupi. Chili ndi transformer yamagetsi yoyezera ndi kuteteza.
Ikhoza kusintha mwachindunji chotsukira mafuta chocheperako cha SW2-35 ndi mitundu yosiyanasiyana ya chotsukira mafuta chozungulira ndi bulaketi yosinthira, komanso imagwiritsidwa ntchito ngati chotsukira tie ndi zochitika zamagulu a capacitor osinthira ndi makina a masika amtundu wa CT14.

Kufotokozera kwa Chitsanzo

Magawo aukadaulo wazinthu ndi miyeso yakunja

Kapangidwe ka zinthu

a. Chotsekera ma circuit ndi kapangidwe kakang'ono ka ceramic kakunja, komwe kali ndi njira yogwirira ntchito ya masika ya CT14; njira ndi gawo lalikulu lolumikizidwa ndi kukhazikitsa kosavuta. Ili ndi mawonekedwe osinthika mosavuta, ntchito yodalirika, yoyenera kugwiritsidwa ntchito pafupipafupi; nthawi yogwirira ntchito ya njira yopitilira nthawi 3000;
b. Gwiritsani ntchito kapangidwe ka mpweya wozimitsa arc-compression, wokhala ndi mphamvu yolimba yophwanya, nthawi zonse zophwanya 40kA mpaka 12, zomwe ndi zapamwamba kwambiri ku China;
c. Kugwira ntchito kodalirika kotseka transformer. Tengani chisindikizo cholowera kunja; chisindikizo chosinthika chimagwiritsa ntchito mphete yotsekera ya "V" yokhala ndi kapangidwe kake kobwezera mphamvu ya kasupe; bolodi lachiwiri la waya logwirizana ndi mabizinesi ogwirizana, kuti zitsimikizire kuti kuchuluka kwa kutayikira kwa pachaka kuli kochepera 1%;
d. Transformer yamkati imagwiritsa ntchito zinthu zamaginito zokhala ndi maginito ambiri, zokhala ndi kalasi yolondola mpaka giredi 0.2 kapena giredi 0.2S. Malinga ndi zosowa za ogwiritsa ntchito, imatha kufananizidwa ndi ma transformer 12, kuti ikwaniritse mzere wonyamula katundu wa makilomita 50 popanda kubwerezabwereza.

Kusankha mtundu wa chinthu

Mkhalidwe wa chilengedwe

1. Kutentha kwa mpweya wozungulira: -5~+40 ndipo kutentha kwapakati sikuyenera kupitirira +35 mu maola 24.
2. Ikani ndikugwiritsa ntchito mkati. Kutalika pamwamba pa nyanja kuti malo ogwirira ntchito asapitirire 2000M.
3. Chinyezi chocheperako sichiyenera kupitirira 50% kutentha kwakukulu +40. Chinyezi chochuluka chimaloledwa kutentha kotsika. Mwachitsanzo, 90% pa +20. Koma poganizira kusintha kwa kutentha, n'zotheka kuti mame ocheperako azitulutsa zinthu mwachisawawa.
4. Kuyika kwa gradient sikuyenera kupitirira 5.
5. Ikani pamalo opanda kugwedezeka kwakukulu ndi kugwedezeka ndipo malowo asakwanire kuwonongeka kwa zida zamagetsi.
6. Chofunikira chilichonse, funsani kwa opanga.
