Ukukhetha i-transformer ngokubanzi kufuneka kuthathelwe ingqalelo ngokupheleleyo kwinkalo yomthamo we-transformer, i-voltage, iimeko zangoku kunye nezokusingqongileyo. Phakathi kwabo, ukukhethwa kwamandla kufuneka kusekelwe kumthamo, ubunjani kunye nexesha lokusetyenziswa kwezixhobo zombane zomsebenzisi ukugqiba umthwalo ofunekayo, ukuze ukhethe umthamo we-transformer. Ngethuba lokusebenza okuqhelekileyo, umthwalo wamandla we-transformer kufuneka ube malunga ne-75% ukuya kwi-90% yomthamo olinganisiweyo we-transformer.

Ukuba umthwalo olinganisiweyo wangempela we-transformer ungaphantsi kwe-50% ngexesha lokusebenza, i-transformer encinci kufuneka ithathelwe indawo, kwaye ukuba inkulu kunomthamo olinganisiweyo we-transformer, i-transformer enkulu kufuneka itshintshwe ngokukhawuleza. Ngexesha elifanayo, xa ukhetha i-transformer, ixabiso le-voltage ephambili ye-winding voltage ye-transformer kufuneka igqitywe ngokuhambelana nomgca wokunikezelwa kwamandla, kunye nexabiso lesibini le-voltage yomoya kufuneka likhethwe ngokwezixhobo zombane. ukukhetha i-voltage ephantsi yesigaba sesithathu sonikezelo lwamandla ombane. Inokubonelela ngamandla kunye namandla okukhanyisa ngexesha elifanayo.

Xa ngokuqhelekileyo sikhetha i-transformer yokusabalalisa, ukuba umthamo ukhulu kakhulu, i-phenomenon ye “trolley enkulu yehashe” iya kwenziwa, engagcini nje ukwandisa utyalo-mali lwezixhobo, kodwa igcina i-transformer kwimeko yokungabikho komthwalo kwi ixesha elide. . , ukwandisa ukulahleka kwamandla asebenzayo; ukuba umthamo we-transformer uncinci kakhulu, i-transformer iya kuba kwimeko egcwele kakhulu ixesha elide, kwaye i-transformer iya kutshisa ngokulula, ingaba i-autotransformer okanye i-transformer yesigaba sesithathu, iyafana. Ngoko ke, ukukhetha umthamo ofanelekileyo we-transformer yenye yamanyathelo abalulekileyo okunciphisa ilahleko kunye nokugcina amandla kwigridi yamandla. Kwizicelo ezisebenzayo, sinokukhetha umthamo we-transformer ngokutsho

kule ndlela ilula ilandelayo.

Inyathelo:

1. Xa ngokuqhelekileyo sikhetha i-transformer yokusabalalisa, ukuba umthamo ukhulu kakhulu, i-phenomenon ye “trolley enkulu yehashe” iya kwenziwa, engagcini nje ukwandisa utyalo-mali lwezixhobo, kodwa igcina i-transformer kwimeko yokungabikho komthwalo. xesha elide. ixesha elide Ukuba umthamo we-transformer uncinci kakhulu, i-transformer iya kuba kwimeko egcwele kakhulu ixesha elide, kwaye kulula ukutshisa i-transformer, ingaba i-autotransformer okanye i-transformer yesigaba sesithathu, iyafana. Ngoko ke, ukukhetha umthamo ofanelekileyo we-transformer yenye yamanyathelo abalulekileyo okunciphisa ilahleko kunye nokugcina amandla kwigridi yamandla. Kwizicelo ezisebenzayo, sinokukhetha umthamo we-transformer ngokwendlela elandelayo elula.

2. Umgaqo othi “umthamo omncinci, ukusabalalisa okuxineneyo” kufuneka kuthotyelwe. I-transformer yokusabalalisa kufuneka ifakwe kwiziko lomthwalo kangangoko kunokwenzeka, kwaye i-radius yombane akufanele idlule i-0.5 yeekhilomitha. Izinga lomthwalo we-transformer yokusabalalisa liphezulu phakathi kwe-0.5 kunye ne-0.6, kwaye umthamo wangoku we-transformer ubizwa ngokuba yi-economic capacity. Nangona kunjalo, ukuba umthwalo uzinzile, umthamo we-transformer unokukhethwa ngokuhambelana nomthamo wezoqoqosho ngokubhekiselele kwimveliso eqhubekayo.

3. Ngokweempawu zabasebenzisi begridi yamandla asemaphandleni abasasazekileyo, ukuxinana komthwalo ophantsi, ixesha eliqinileyo kunye nomthwalo oqinileyo ophakathi, njl., i-transformer yokulungiswa kwamandla ingasetyenziswa. I-capacity regulating transformer yi-transformer ekwazi ukulungelelanisa umthamo ongekho umthwalo ngokobungakanani bomthwalo, olungele ukusetyenziswa kwiindawo apho utshintsho lwexesha lonyaka kumthwalo lubonakala ngokucacileyo. Kwizitishi okanye amashishini kunye nemigodi kunye nemithwalo yamandla amakhulu, i-transformer engundoqo kunye ne-subsidiary isetyenziselwa ukunikezelwa kwamandla, enye (umama) iqulunqwe ngokomthwalo ophezulu, kwaye enye (yesibini) ikhethwe ngokweemeko zomthwalo ophantsi. , enokuphucula kakhulu ukuhanjiswa kwamandla. Ukusetyenziswa kwe-transformer, kunciphisa ilahleko engekho mthwalo kwii-transformers zokuhambisa. Ngenxa yokuba ezinye iinguqu zokusasaza kwiindawo ezisemaphandleni zisebenza ixesha elide ngaphandle kwenani elincinci leencopho zombane ngonyaka, kubasebenzisi abaneemeko, i-transformer unina-nyana okanye i-transformer parallel yokusebenza amandla. iindlela zokubonelela nazo zingasetyenziswa. Xa umthwalo uguquka kakhulu, ngokomgaqo wokulahlekelwa kwamandla aphantsi, uwubeke kwi-transformer kunye nomthamo ohlukeneyo. Kwiziguquli ezikhethekileyo ezinikezela kuphela amandla kwimithwalo yamandla efana nokunkcenkceshela kunye nokuhambisa amanzi, umthamo we-transformer unokukhethwa ngokubanzi ngokwe-1.2 amaxesha e-asynchronous motor nameplate amandla. Ngokuqhelekileyo, i-motor yokuqala yangoku iphindwe kane ukuya kwasixhenxe ngoku irethiweyo, kwaye i-transformer kufuneka ikwazi ukumelana nale mpembelelo.Umthamo wenye yeenjini ezinkulu eziqala ngokuthe ngqo akufanele zigqithise malunga ne-30% yomthamo we-transformer. Kufuneka kucaciswe ukuba ii-transformers ezikhethekileyo ze-drainage kunye nokunkcenkceshela akufanele zidibaniswe neminye imithwalo, ngaloo ndlela imise ukusebenza ngexesha ngexesha lokungakhuseli kunye nokunkcenkceshela kunye nokunciphisa ukulahlekelwa kwamandla ombane.
