Parallel kushanda transformers - Conditions

Energy - vagara chinokosha yebudiriro. Pasina izvozvo, fungidzira upenyu hazviiti. Ndokusaka mubvunzo pamusoro chamazuva kwesimba wedzerai vatengi ari kuramba chakasimba. Cheteyo kushanda transformers - mumwe nzira idzi. Zvisinei, kana chete negadziriro yeparutivi kushandisa nzira, uye ndedzipi zvinodiwa kuti midziyo?

Nei vachifanira neiyi kushanda transformers?

Sezvataurwa pamusoro apa, pakutanga akabvuma basa rave kwakakonzerwa kudikanwa kuvandudza rakavimbika simba zvitengeswa. Zvisinei, pane dzimwe, hakukoshi, kunyanya kana yakafanana kushanda transformers kunodiwa. pfungwa idzi dzinosanganisira:

• nokukurumidza yakawedzera mutoro, izvo munguva pfupi zvichaita pfuura (kana akapfuudza) munhu achishanda simba transformer;
• kushaya nzvimbo (urefu, upamhi) havagoni mari kumisa imwe transformer guru, asi unogona kuisa duku mbiri uye kuvabatanidzira zvakafanana;
• Sezvingatarisirwa, kuchengeteka matanho hunoita basa rinokosha, sezvo mukana kufoira panguva kamwe vose transformers yakaderera chaizvo, asi zviri, saka kunze chiitiko ichi, yakafanana mukushanda transformers, kushandisa dzimwe negadziriro yeparutivi nzira.

Kuisa kupinda kushanda transformers maviri

Achitendeukira transformers nokuti zvakafanana oparesheni kunopa redundancy vagamuchiri kunyanya kukosha yemagetsi simba, zvinoratidza risina kumiswa simba zvitengeswa. On ruzhinji substations anoshandiswa, vaviri kana kupfuura transformers (kunze uri mutete hutachiwana mhando substation). Kushanda zvakafanana anobvumirwa, kana zvose transformer neumwe akagadzirwa zvinodiwa, vanonzi "zvinhu zviri zvakafanana kushanda transformers":

• boka windings vanofanira kuva akafanana nomumwe;
• Kushandurwa ratios kuva akaenzana mumwe, uve insubstantial kutsauka mukati zvinogamuchirika kwezvipimo mitemo;
• voltage nematunhu pfupi anofanira kuva akaenzana mumwe, zviri insubstantial kutsauka mukati zvinogamuchirika kwezvipimo mitemo;
• dzakafanana transformers vanosungirwa kuti dzinofambiswa kubva chete samambure;
• yechipiri netambo inodiwa unobva transformer zvokusvika anofanira anenge akaenzana maitiro uye urefu;
• danho kuchinja pakati voltages ari nesekondari windings kunge zvakafanana.

Kudiwa rokutanga kukarukureta

Kana kuzotadzira mumwe transformers mbiri haisi nguva zvichiita kuti kusarudza zvakangofanana, izvo zvakazara Unotibatsira ukama ezvinhu uye uchishandisa modes. Muzviitiko izvi, rakasanangurwa pakati transformer makateyiwa pamusoro dzakaoma kunzwisisa rokutanga Masvomhu zvinoratidza kuti vaviri windings ari transformer ichaparadzwa akatakura zvakaenzana, uye kana imwe yadzo Takudzai akapfuudza kukwanisa mumwe nomumwe transformer.

Short-redunhu voltage

Cheteyo kushanda transformers zvinowanikwa pachidiwa kuenzana tsika voltage pfupi mumatunhu ari windings. Kana zvakasiyana tsika RS, asati Kuenda vagari basa zvakafanira kare kushandura kuchinja reshiyo of transformers chaiwo chinja. Saka zvinoita kuti vabudirire muripo kubva redistributed kunetseka izvo inomuka nokuda misiyano pfupi redunhu voltages. Anomuka nokuda mumwe mismatch yakadaro yokuenzanisa dzenzvimbo havangadyi wakaremedza kuti transformer pamwe yakaderera mhosva voltage.

Chokwadi, unofanira kufungawo kutakura - kana oga mumwe mudziyo, uye panguva zviitiko zvakadai yakafanana ichishanda simba transformers. Zvisinei, panguva usimbe, musiyano uri zvachose hapana simba iri tsika pakati pfupi-redunhu voltage, nekuti kushandurwa ratios vari equalized uye kuva zvakafanana. Under mutoro, asi voltage yechipiri uchava akasiyana, nokuti dzisakarurama voltage donhwe zvingakonzera leakage compensating dzenzvimbo nokuda windings, pamwe chete transformer compensating kuitika inobatanidzwa pamwe nechigadziko, uye wechipiri subtracted. The yakarumbidza reshiyo chakasimba zvikuru vanokwanisa kuti yakaderera chaizvo simba transformer anofanira kuva asina kupfuura vatatu mumwe.

Available ezvinhu

Parallel mukushanda transformers, vatatu-ichitenderera, mbiri-ichitenderera dzose windings. Zvinofanira kurangarirwa kuti midziyo yemagetsi chokuita mu dzakafanana, mutoro iri akaparadzirwa Ivan Kuchin maererano pfupi-redunhu voltage uye Proportional nesimba mumwe nomumwe transformer zvakananga. Cheteyo mukushanda transformers, kana ichitenderera mapoka kubatana zvakasiyana, zvinokwanisika zvachose vasinganzwisisike mapoka. Kana usanganidzo isina chikwata, ipapo nokuda rekona kuchinja pakati zviteshi ari yechipiri windings pane voltage hunokonzera ane zvisingagamuchirwi pakaitika ano.
