Chii chinonzi 25 kVA Transformer

Transformer ye25 kVA inobata simba guru rinoonekwa re25,000 volt-amperes (VA), iro rinogadzirwa nevoltage ne current mu AC circuit.

"25" mu25 kVA inoreva kugona kukuru kwetransformer kubata simba rinooneka, kwete simba rayo chairo rinobuda. Kuti uone simba chairo rinobuda, funga nezvesimba remutoro wakabatana. Transformer ye25 kVA ine simba re0.8 ine simba chairo rinobuda re20 kilowatts (kW).

Ma voltage ekupinda nekubuda akajairika

Mavoltage emagetsi anobuda e25 kVA transformers anowanzo sanganisira 208V, 240V, uye 120V. 208V ne240V zvinoburitsa magetsi mumidziyo mikuru, senge mota, michina inorema, uye midziyo ine simba guru. 120V inobuda yakakodzera midziyo midiki, mwenje, uye midziyo yehofisi.

Mhando dze25 kVA Transformers

Single Phase Transformers

Matransformer echikamu chimwe chete anowanzo shandiswa pakushandisa simba re25 kVA. Matransformer aya ane mawinding maviri: yekutanga neyechipiri. Anoshanda pachikamu chimwe chete chemagetsi anoshandiswa pamagetsi (AC), zvichiita kuti akwanise kushandiswa mumagetsi emumba uye emumabhizinesi.

Matatu eMatanho ekuchinja

Matransformer emhando yechitatu ane 25 kVA anoshandiswa zvakanyanya mumaindasitiri nemabhizimisi pakushandisa simba guru. Anopa simba rakawanda uye rakaenzana kana tichienzanisa nematransformer emhando imwe chete, zvichiita kuti akwanise kubata mitoro mikuru. Matransformer aya ane mawinding matatu akasiyana, chikamu chimwe nechimwe chakaparadzaniswa nemadhigirii zana nemakumi maviri, zvichiita kuti pave nemagetsi akasimba uye anoramba achishandiswa.

Matransformer echikamu chetatu ane mabhenefiti akawanda pane matransformer echikamu chimwe chete. Anobvumira kuderedzwa kwehukuru hwemutyairi, kuvandudzwa kwesimba remagetsi, uye kudzorwa kwemagetsi kuri nani. Pamusoro pezvo, anoderedza kukanganiswa kwesimba remagetsi, zvichikonzera simba rakagadzikana remidziyo inoteerera.

Madiro Akakosha uye Zvimiro

Kugona kubata simba uye mutoro wekutarisira

Transformer ye25 kVA ine simba guru rinoonekwa re25,000 volt-amperes (VA). Simba rinoonekwa rinobuda kubva pavoltage ne current mu AC circuit. Simba chairo rinounzwa kumutoro, rinozivikanwa sesimba chairo (rinoyerwa muma watts), rinenge riri shoma pane simba rinoonekwa nekuda kwesimba rezvishandiso zvakabatana.

Nzira dzekutonhodza (ONAN, ONAF) uye mazinga eruzha

ONAN (Oil Natural Air Natural) neONAF (Oil Natural Air Forced) ndidzo nzira mbiri huru dzekutonhodza ma transformer e 25 kVA. Kutonhodza kweONAN kunoenderana ne convection yechisikigo yekutenderera kwemafuta uye kupisa, zvichiita kuti ive sarudzo yakanyarara yakanakira nzvimbo dzekugara uye dzinonzwa ruzha. Zvisinei, ONAN ine kushanda kwakaderera kwekutonhodza kana tichienzanisa neONAF.

Kutonhodza kweONAF kunoshandisa mafeni kumanikidza kutenderera kwemhepo yakatenderedza transformer, zvichiwedzera kupisa uye zvichiita kuti mutoro uwedzere. Kunyange zvazvo ichishanda zvakanaka kupfuura ONAN, ONAF inogadzira ruzha rwakawanda nekuda kwemafeni.

Matransformer eONAN anowanzova neruzha rwunosvika 40-50 dB, nepo matransformer eONAF achigona kusvika 60-70 dB.
Zvinhu Zvinokanganisa Mazinga eruzha

Zvishandiso zvekudzivirira zvinodarika mwero uye sarudzo dzekubatanidza

Zvishandiso zvekudzivirira magetsi akawandisa, zvinosanganisira macircuit breakers, mafuse, uye ma thermal overload relays, zvinodzivirira ma transformer e25 kVA nemidziyo yakabatana kubva kumagetsi akawandisa anokonzerwa nekuwanda kwemagetsi, ma short circuits, kana mamiriro ekutadza.

• Macircuit breaker anogadzirisa marongero ekufamba uye anogadzirisa zviri nyore mushure mekugumburwa. Mafuse anopa dziviriro inoshanda nekukurumidza asi anoda kutsiviwa kana aputika.
• Marelay ekupisa anotarisa tembiricha yetransformer uye kudonha kwayo kana miganhu yakatarwa yadarika.
• Mafusi anoganhurira magetsi anokurumidza kukanganisa magetsi emagetsi, zvichideredza kukuvara. Mafusi anodzinga magetsi anoshandisa zvinhu zvinochinja-chinja gasi kudzima ma arcs. Mafusi anofanirwa kuenderana nemagetsi e transformer uye ma short-circuit capacity kuti dzivirirwe zvakanaka.

Insulation uye weatherproofing

Zvinhu zvinodzivirira kupisa zvematransformer e25 kVA zvinosanganisira epoxy resins, silicone rabha, uye polyurethanes. Zvinhu izvi zvinopa simba guru re dielectric, kuramba hunyoro, makemikari, uye tembiricha yakanyanya, pamwe nesimba remakanika uye kugara kwenguva refu.

Kudzivirira mamiriro ekunze kwakakosha pakuisa matransformer ekunze . Zvivharo zvisingapindi ngura zvakagadzirwa nesimbi isingatsvedzi kana aruminiyamu, pamwe chete nemagasket nezvisimbiso, zvinodzivirira kupinda kwemvura neguruva. ​​Kufefetera kwakakwana kunoderedza kupisa uye kudzivirira kunyorova. Zvimwe zvekudzivirira munzvimbo dzakaoma zvinosanganisira machira ekudzivirira ngura, mafinishes anodzivirira UV, uye maronda.

Mapombi uye kugadziriswa kwekutonga kwemagetsi

Mapombi, nzvimbo dzekubatanidza pa transformer windings, zvinobvumira kugadziriswa kwe voltage output mu 25 kVA transformers. Mapombi akawanda anopa mhando dzakasiyana dze voltage, kazhinji ±5% kana kupfuura, kuti ienderane nezvinodiwa uye idzore kudzikira kwe voltage.

Maswichi epombi asingapinze mutoro anogonesa shanduko dzemagetsi pasina kubvisa transformer kubva pamagetsi. Anorerutsa kugadziriswa kwemagetsi uye anoderedza nguva yekushanda.

Zvinhu zvinomonereka (aruminiyamu vs. mhangura) uye zvazvinoreva

Mawinding emhangura anopa simba repamusoro rekufambisa magetsi, zvichikonzera kurasikirwa kushoma uye kushanda zvakanaka zvakanyanya kana tichienzanisa nearuminiyamu. Kusagona kwemhangura kurumwa nengura uye simba rayo remuchina zvinobatsira kuti transformer igare kwenguva refu uye yakavimbika.

Mawinding ealuminium, kunyange zvazvo asingafambise simba zvakanyanya semhangura, anopa mabhenefiti akawanda mukugadzirwa kwetransformer. Huremu hwayo hwakareruka hunoderedza huremu hwetransformer, zvichiita kuti kubata kwayo nekufambisa zvive nyore. Kuramba kwayo zvakanyanya kusimba kwe short-circuit kunoita kuti transformer igare kwenguva refu, zvichiita kuti isakuvadzwe zvakanyanya nemagetsi.

Kuyera uye kuyerwa

Saizi yetransformer ye 25 kVA inowanzova 24-30 inches pakureba, 18-24 inches paupamhi, uye 24-30 inches pakureba.

Kurema kuri pakati pe400-600 pounds, zvichienderana nezvinhu nezvimwe zvinhu zvakaita semafin ekutonhodza kana mabhureki ekukwirisa.
