Kodi Reverse Power Protection of Jenereta Set ndi chiyani

Monga mwini ndi wogwiritsa ntchito jenereta, wogwiritsa ntchitoyo ayenera kumvetsetsa mbali zonse za jenereta, kuti adziwe bwino momwe angagwiritsire ntchito ndikugwiritsa ntchito njira za seti ya jenereta.Masiku ano kampani ya Dingbo Power imagawana chitetezo chamagetsi chamtundu wa jenereta.

Jenereta set reverse mphamvu chitetezo amatchedwanso mphamvu malangizo chitetezo.Nthawi zambiri, mphamvu ya jenereta iyenera kukhala kuchokera ku jenereta kupita ku basi.Komabe, pamene jenereta wataya chisangalalo kapena pazifukwa zina, jenereta akhoza kusintha ntchito galimoto, ndiko kuti, kuyamwa mphamvu yogwira ku dongosolo, amene ndi n'zosiyana mphamvu.Mphamvu yakumbuyo ikafika pamtengo wina, chitetezo cha jenereta chimagwira, kapena kuchitapo kanthu powonetsa kapena kuyenda.

Ntchito yofananira ya seti ziwiri za jenereta ya dizilo iyenera kukwaniritsa magawo omwewo amagetsi a jenereta, ma frequency omwewo jenereta yamagetsi ndi gawo lofananira la seti ya jenereta.Pogwiritsira ntchito, pamene ma seti awiri a jenereta a dizilo akufanana popanda katundu, padzakhala vuto la kusiyana kwafupipafupi ndi kusiyana kwa magetsi.Nthawi zina mphamvu yeniyeni yosinthira imapezeka ndi chida chowunikira, chomwe ndi mphamvu yobwerera kumbuyo chifukwa chamagetsi osagwirizana.Wina ndi ntchito yobwerera kumbuyo yomwe imayambitsidwa ndi liwiro losagwirizana (mafupipafupi).Pamaso pa chodabwitsa ichi, kusintha kofananira kuyenera kupangidwa.

1.Kusintha kwa mphamvu ya reverse chifukwa cha kusiyana kwa magetsi.

Pamene chisonyezero cha mita ya mphamvu zonse ziwiri zomwe zimapanga ndi ziro ndipo ammeter akadali ndi chisonyezero chamakono, chowongolera chamagetsi cha seti imodzi ya jenereta ya dizilo chikhoza kusinthidwa molingana ndi kuwonetsera kwa ammeter ndi mphamvu.

2.Kusintha kwa mphamvu yobwerera kumbuyo chifukwa chafupipafupi.

Ngati mafupipafupi a mayunitsi awiriwa ndi osiyana ndipo kusiyana kwake kuli kwakukulu, mawonekedwe a unit omwe ali ndi liwiro lalikulu amasonyeza mtengo wabwino ndipo mita yamagetsi imasonyeza mphamvu zabwino.M'malo mwake, zamakono zimasonyeza mtengo woipa ndipo mphamvu imasonyeza mtengo woipa.

Panthawiyi, sinthani liwiro la seti imodzi ya jenereta ya dizilo ndikusintha mawonekedwe a mita yamagetsi mpaka ziro.Komabe, pamene ammeter akadali ndi chisonyezero, ichi ndi chodabwitsa cha mphamvu chosinthika chifukwa cha kusiyana kwa magetsi.

Nthawi zambiri, kulumikizana kofananira kwa seti ya jenereta ya dizilo sikungabweretse mphamvu yosinthira.Majenereta ochepa okha omwe ali ndi mphamvu zochepa zotulutsa mphamvu chifukwa cha malamulo osayenera akalumikizidwa ndi gridi.Tiyenera kupenda zomwe zimayambitsa mwamsanga ndikuchitapo kanthu koyenera kusintha.

Kodi ntchito ya jenereta reverse mphamvu chitetezo ndi chiyani?

Pamene kuposa awiri dizilo jenereta akanema ntchito limodzi, ngati injini dizilo wa wina dizilo jenereta seti sachiza bwinobwino kapena kufanana pakati pa injini dizilo ndi jenereta kuwonongeka, jenereta wa unit sangathe linanena bungwe mphamvu yogwira, koma kuyamwa. mphamvu kuchokera kumagetsi opangira magetsi, ndipo jenereta yolumikizana imakhala injini yofananira, ndiye kuti, jenereta yolumikizira imagwira ntchito mosinthana.

Ngati jenereta ya synchronous imagwira ntchito mosinthana ndi mphamvu, sizingakhale bwino pamagetsi, zomwe zimapangitsa kuti mayunitsi ena omwe akutenga nawo gawo azichulukirachulukira. ntchito yofanana ndi kusokoneza kwa magetsi.Choncho, njira ziyenera kuchitidwa pofuna kubwezera kumbuyo mphamvu.

Titha kugwiritsa ntchito chipangizo choteteza mphamvu cha transistor.

Popeza chitetezo chakumbuyo ndi chitetezo champhamvu champhamvu, chizindikiro chake chodziwikiratu chiyenera kutenga ma voliyumu ndi apano komanso ubale wawo, ndikusintha kukhala siginecha yamagetsi ya DC yowonetsa komwe akuchokera komanso kukula kwa mphamvu yogwira.

Chizindikiro chakumbuyo chachitetezo chamagetsi cha chipangizocho chimatengedwa kuchokera ku voteji komanso pakalipano ya gawo la S la jenereta kuti izindikire mphamvu yagawo limodzi.M'magawo ake opangira magetsi, mbali zoyambira za ma voliyumu M1 ndi M2 zimalumikizidwa kukhala nyenyezi zofananira, ndipo voteji Uso' imatengedwa ngati siginecha yamagetsi.Ndipo pangani Uso' mu gawo ndi gawo lamagetsi la USO lotulutsa ndi jenereta.Chizindikiro chake chapano chimapezedwa ndi thiransifoma ya S-gawo ndikukonzedwanso ndi mabwalo awiri okonzanso mlatho wagawo limodzi VD1 ndi VD2.Mu voteji U1 ya resistor R3, voteji U2 ya resistor R4 ndi ulalo wozindikira mphamvu, mfundo yofananira yamtengo wapatali idzagwiritsidwa ntchito pozindikira.Pamene R1 = R2, DC control signal voltage UNM imatulutsa ndi ulalo wozindikira mphamvu imagwirizana mwachindunji ndi mphamvu yogwira P ndikuwonetsa komwe P. M'malo obwerera kumbuyo, voteji ya DC yowongolera siginecha UNM ndi yolakwika, ndiye kuti, N. -kuthekera kwa mfundo ndikwambiri kuposa kuthekera kwa m-point.Pamene mphamvu yakumbuyo ifika 8% ya mphamvu yovotera ya jenereta, triode VT1 imayatsidwa ndipo VT2 yazimitsa.Mphamvu yogwira ntchito imayitanitsa capacitor C kudzera pa resistors R15 ndi R16, ndikuchedwa kwapakati pafupifupi 5s.Mphamvu yamagetsi ya capacitor C ikafika pakuwonongeka kwa voteji yokhazikika ya chubu W1, chubu W1 imayatsidwa, diode VD3 ndi triode VT3 imayatsidwa, cholumikizira D1 chimayatsidwa ndikuchita, ndipo chosinthira magetsi chimayenda zokha, kuti akwaniritse cholinga chachitetezo.

Ngati mukufuna seti ya jenereta ya dizilo, lemberani kampani ya Dingbo Power ndi imelo dingbo@dieselgeneratortech.com.
