Zofunikira ndi Mapangidwe a Jenereta Excitation Regulator

1. Zofunikira za chowongolera chosangalatsa

1) Kudalirika kwakukulu ndi ntchito yokhazikika.Njira zofananira ziyenera kuchitidwa pakupanga madera, kusankha zigawo ndi kukonza msonkhano.

2) Kukhazikika kokhazikika komanso mawonekedwe osinthika.

3) Nthawi yokhazikika ya chowongolera chosangalatsa iyenera kukhala yaying'ono momwe mungathere.

4) Kapangidwe kake ndi kophweka, kukonza ndi kukonza ndikosavuta, ndipo pang'onopang'ono kumakwaniritsa dongosolo, kukhazikika komanso kukhazikika.

2. Kupangidwa kwa chowongolera chosangalatsa

Jenereta semiconductor excitation regulator imapangidwa makamaka ndi magawo atatu ofunikira: kufananitsa muyeso, kukulitsa momveka bwino ndi choyambitsa gawo.Chigawo chilichonse chimapangidwa ndi maulalo angapo.

1) Muyezo woyerekeza woyezera umakhala ndi kuyeza kwamagetsi, kufananiza ndi kusintha.Gawo la kuyeza kwamagetsi limaphatikizapo kuyeza koyezera ndi kusefa, ndipo ena amakhala ndi zosefera zotsatizana bwino.Chigawo choyerekeza choyezera chimapangidwa kuti chiyezetse voteji ya DC yosinthidwa molingana ndi voteji ya jenereta ndikuyifananitsa ndi voteji yofananira yofananira ndi voteji yoyezera ya jenereta kuti ipeze kupatuka kwa voteji ya jenereta kuchokera pamtengo wake.Chizindikiro chopatuka cha voteji chimalowetsedwa kugawo lophatikizika la amplifier, ndipo sefa yotsatizana yabwino yamagetsi imatha kuwongolera kulondola kwa chowongolera pomwe jenereta ikugwira ntchito mosagwirizana, ndipo imatha kupititsa patsogolo luso lachisangalalo pamene gawo lalifupi la asymmetric lichitika.Ntchito ya ulalo wosinthika ndikusintha koyezetsa kosintha kwa wowongolera kuti atsimikizire kugawa kokhazikika komanso koyenera kwa mphamvu yogwira ntchito pakati pa gensets mu ntchito yofananira.

2) Chigawo chokwanira cha amplification chimapanga ndikukulitsa chizindikiro choyezera, kuti mupeze mawonekedwe abwino komanso osinthika adongosolo losinthira ndikukwaniritsa zofunikira pakugwirira ntchito, kuphatikiza pamagetsi opatuka pazida zoyambira, nthawi zina ndikofunikira phatikiza ma siginecha ena monga ma sigino okhazikika, ma siginecha ochepera, ndi ma siginecha achipepeso kuchokera ku chipangizo chothandizira malinga ndi zofunikira.Chizindikiro chophatikizika chowongolera chimalowetsedwa kugawo losinthira gawo.

3) Gawo losinthira magawo limaphatikizapo kulumikizana, kusuntha kwa gawo, kupangika kwa pulse, ndi kukulitsa kugunda.Malinga ndi kusintha kwa chizindikiro chowongolera, gawo losinthira magawo limasintha gawo la choyambitsa kugunda kwa thyristor, ndiye kuti, kusintha mawonekedwe owongolera (kapena gawo losuntha), kuti muwongolere voteji ya thyristor rectifier dera kuti musinthe ma excitation apano a jenereta.Kuti muyambitse kugunda kwa thyristor modalirika, nthawi zambiri ndikofunikira kugwiritsa ntchito ulalo wokulitsa mphamvu ya pulse kuti mukweze mphamvu.

Chizindikiro cha kalunzanitsidwe amatengedwa kuchokera ku lupu waukulu wa thyristor rectifier, kuonetsetsa kuti choyambitsa kugunda limatulutsa pamene thyristor anode voteji ali mu positive theka mkombero, kuti choyambitsa kugunda ndi synchronized ndi kuzungulira waukulu.

Nthawi zambiri pamakhala gawo lamanja mu dongosolo excitation .Pamene gawo lodziwikiratu la chowongolera chokomera likulephera, limatha kusinthidwa kukhala mawonekedwe amanja.

Zomwe zili pamwambazi zikugawidwa ndi Dingbo Power, katswiri wopanga magetsi OEM.Dingbo Power ndi kampani yomwe ili ndi zaka zopitilira 15 yopanga jenereta ya dizilo, kupereka, kutumiza ndi kukonza ntchito imodzi.Timapatsa ogwiritsa ntchito zida zosinthira, upangiri waukadaulo, kukhazikitsa malangizo, kutumiza kwaulere, kukonza kwaulere, ndi ntchito zophunzitsira anthu kwa nthawi yayitali.Ngati muli ndi chidwi ndi jenereta yathu ya dizilo, talandilani kutumiza imelo ku dingbo@dieselgeneratortech.com kuti mupeze mtengo tsopano!
