Zonse zokhudzana ndi kusintha kwa magawo atatu

Gawo lotembenuza magawo atatu limagwiritsidwa ntchito kusintha magetsi. Chipangizo chimagwiritsidwa ntchito mmagetsi opangira mafakitale ndi zosowa zapakhomo. Kuwonjezera pamenepo, zipangizo zimenezi ndi zofunika kwambiri pa zombo, popeza zimagwiritsidwa ntchito ku zipangizo zamagulu a zipembedzo zosiyanasiyana.

Gawo loyamba la magawo atatulo likuwerengedwa molingana ndi zolemba zapadera. Pogwiritsa ntchito chidziwitso chomwe adachipeza, chofunika chogwiritsira ntchito chimasankhidwa. Chipangizochi sichigwiritsidwa ntchito pazinthu zamakampani zokha, komanso m'nyumba zamagetsi popanga maulendo oyendetsa magetsi.

Gawo loyamba la magawo atatu likhoza kuchepa kapena kuwonjezeka, chiwerengero cha miyeso yotembenuzidwa chimadalira kuchuluka kwa maulendo onse awiri. Chipangizocho chikhoza kusonkhanitsidwa kuchokera ku zigawo zitatu zosagwiritsidwa ntchito limodzi kapena kuchita chimodzimodzi, chiwerengero cha magnetic fluxes pa gawo lililonse mu chipangizochi chidzakhala zero.

Kwa osintha mafakitale, mayesero angapo amachitidwa kuti atsatidwe ndi magawo ena. Makhalidwe otsimikizira kuti zida za chipangizochi zikuphatikizapo kukanikiza kutsutsana, kuyang'ana kusungunula pansi ndi pakati pa magawo. Chipangizo chapadera chimapereka magetsi kupita ku windings ndipo chimatsimikizira kuwonongeka kwa mphamvu yokopera. Mphamvuyi imagwiritsidwa ntchito pokhapokha ngati mphepo ikuyendera ndipo mtengo wake umatengedwa. Pogwiritsa ntchito chidziwitso ichi, chiŵerengero cha kusinthidwa chiwerengedwa.

Zotsatira za mayeso ziyenera kukhala zofanana ndi zomwe zikuwonetsedwa m'malemba omwe ali pambaliyi, mwinamwake osintha magawo atatu akutsutsidwa. Ndikofunika kumvetsetsa kuti kumanga ndi kukonza zipangizo za 110 kV ndi apamwamba a switchgears sikuloledwa popanda kuyang'aniridwa ndi katswiri kuchokera ku fakitale kumene opangidwayo anapangidwa. Pankhaniyi, mayeserowa ayenera kuchitidwa malinga ndi malamulo ovomerezeka pamaso pa munthu woyenerera.

Gawo loyamba la magawo atatu likugwirizana mogwirizana ndi dongosolo la "Star" kapena "Triangle". Kulumikizana kwa nyenyezi kumatsimikiziridwa ndi mfundo yamba ya kuyamba kwa magawo onse. Chiwembucho mwa mawonekedwe a katatu chimapangidwa ndi mndandanda wothandizira magawo mu mphete: mapeto a gawo loyambalo akugwirizana ndi kuyamba kwachiwiri, kutha kwachiwiri ndi kuyamba kwachitatu ndikumapeto kwachitatu ndi chiyambi cha choyamba.

Ngati gawo la magawo atatu la magawo atatu likugwirizana mogwirizana ndi ndondomeko ya "Nyenyezi", ndiye kuti zinthu zikhoza kuchitidwa ndi malo osasunthika kapena osalowerera nawo mbali (otchedwa node omwe akugwirizanitsa mapeto a magawo). Pogwiritsa ntchito mkulu wa voltage switchgears, ambulera yapadera imagwiritsidwa ntchito, yomwe imalola kuti pakhale kusalowerera ndale. Komabe, kusinthana kwapakati pa 0,4 kV kumagwiritsa ntchito zero.

Kuteteza mizere ya magetsi, magetsi otembenuza amagwiritsidwa ntchito poletsa mphamvu. Zimathandizira kuteteza chitetezo m'makona ndi makondomu pamene akusintha kusiyana kwa kagwiritsidwe ntchito ka zipangizo. Kawirikawiri, atatu otembenuza amagwiritsidwa ntchito pa gawo lililonse.

Aliyense wa iwo ali ndi makilogalamu awiri: imodzi imagwirizanitsidwa ndi katatu yotseguka, inayo ndi nyenyezi. Nyenyezi imatha kuyesa magetsi pamitsinje, ndipo katatu yotseguka ndi kofunikira ngati chitetezo kufupi ndi kayendetsedwe kaifupi.

Masiku ano, voltage transformers ndi gawo lachitatu limapangidwa pansi pa akaunti. Ikugwirizanitsa counters. Monga lamulo, gawo lachitatu likugwirizananso molingana ndi dongosolo la nyenyezi. Kulekanitsa kwa maulendo oyendetsa kuchokera kumadera owerengetsera kumathandizira kuti muwerenge molondola, chifukwa kalasi yolondola ya chiwerengero ndi yapamwamba.
