Kutanga kuitika

Kana zvaisanganisira mukushanda chero midziyo, mashandiro kana mudziyo kwenguva nguva iyo kune pezvakaitwa, makatumidzwa non-mira kana launchers. Mienzaniso inozivikanwa kwazvo upenyu - kutama, ngatitaurei vanoti, mumwe akatakura rori, chitima, zvakajeka zvikuru zvinoratidza kuti kwokutanga simba wedzera inowanzopiwa kunodiwa kupfuura nesimba mune ramangwana.

Dambudziko rakadai kuitika zvemagetsi zvemhando: nemwenje, Motors, electromagnets, etc. Kutanga pezvakaitwa mu namano izvi zvinoenderana mamiriro basa zvinhu: filament marambi, mamiriro magnetization pakati chinoumba ane electromagnet coils, ukuru ionization of interelectrode mukaha mumarudzi gasi zvinoerera marambi , etc. Somuenzaniso, funga filament chechiedza girobhu racho. Zvinonyatsozivikanwa kuti muna kuchitonhora mamiriro, ine zvikuru yakaderera nemishonga pane apo
neshungu kusvika 1000 inegumi. ari uchishandisa muoti. Edza kuverenga kurwisa
filament nokuti 100-watt girobhu racho - vanenge 490 ohms, uye ohmmeter akayera mu simbe ezvinhu zviri asingasviki 50 ohms. Zvino kupfuura kunakidza - kuverenga inrush ano, uye iwe Vachanzwisisa nei Mabumba vari yakavhenekerwa kana anobatidzwa.

Zvakaratidza kuti kana magetsi dzikava pamusoro kunosvika 4-5 A, riri simba kudyiwa anopfuura 1 KW. Saka nei ane 100-watt chiedza Mabumba regai kupisa, "pasina chakasara"? Hongu nokuti, kudziyisa, chiedza girobhu racho filament ane
kuwedzera nemishonga, izvo zviri rakadzikama mamiriro inova kugara, hombe kwokutanga kukosha, uye ichikutadzisa iri uchishandisa kwazvino kumativi 0.5 A.

Electric Motors vane paupamhi kushanda ari unyanzvi, saka ruzivo zvainyanya zvavo pokutangira zvatariswa inokosha kuti zvakakodzera oparesheni eletroprivodov. Vapedzisire uye torque pamusoro nomubato - chikuru kukanganisa kutanga iyezvino pazviruva. Kutanga asunga remagetsi munda kutenderera nokukurumidza uye rotor pakukurumidza yakatarwa nokukurumidza zvinoderedza kubva 1 kushoma kukosha, uye wechipiri anosarudza mashoko zvokuimba mutoro pamusoro mugodhi, kufadza pakutanga kutanga-uye mushure aizviti zvizere kumhanyisa. Asynchronous injini munguva run-kusvikira vakaenzana transformer pfupi-circuited yechipiri ichitenderera. Nokuda kwayo duku
Kupikiswa kutanga kuitwa injini payakakurudzirwa zvasvika munhu zvakapetwa kagumi nekumwisa yayo yavose sezvavakatarirwa ukoshi.

ano Kusasvika rotor windings zvinoita saturation pamusoro makirisito kuwedzera simba remagineti, pakuonekwa ane emf kuzvipira inductance, iyo inosvitsa nokuwedzera inductive
redunhu nemishonga. The rotor inotanga tenderera, uye pitikoti reshiyo zvinoderedza, i.e., It Inowedzera injini. Panyaya iyi yokutanga anoshandiswa kumuka nemishonga zvinoderedza kune vachiwana ukoshi.

Matambudziko anokonzerwa panowanikwa yakawedzera inrush dzenzvimbo inomuka
nokuda overheating pamusoro dzemagetsi Motors, ari zadzisa kuti magetsi network panguva
kutanga-kumusoro, panowanikwa zvokuimba kuvhunduka mitoro zvakabatanidzwa mashandiro yakadai rachulis. Kune mapoka maviri mano kuti kugadzirisa mibvunzo iyi yazvino - nyoro Mutange uye maitikiro converters.

sarudzo dzavo - kuti ive ouinjiniya dambudziko pamwe kuongorora zhinji woshanda
unhu. The mutoro chaiwo ezvinhu enyika kushandisa dzemagetsi Motors rakakamurwa mapoka maviri: pombi-dzinoshandisa uye mukuru. Soft Mutange vari kudiwa kushandiswa mitoro feni chikwata. regulators kwakadaro kutirambidza inrush razvino kune pamwero kwete kupfuura 2 chezita tsika, panzvimbo 5-10 nguva vanhuwo kutanga-kumusoro, nokuda kuchinja voltage windings.

Yainyanya kushandiswa indasitiri vari dzemagetsi Motors kuti rakatumbuka ano. Zvisinei, avo vasina mano magadzirirwo uye pasi mari ndiyo negwara - rinorema pokutangira ezvinhu kuti vasanyanya pachishandiswa maitikiro converters. A zvikuru chinokosha chinoratidza maitikiro
transducer rutsigiro inrush ano induction injini kuti
nguva refu - kweminiti kana kupfuura. Mienzaniso yakanakisisa converters ano vakangwara mano uchishanda kwete kutanga kuzvidzora muitiro, asiwo optimize kutanga pamamiriro mabasa nzira: pezvemakuriro uye kupfuurira yokutanga kuitika, asi zvishoma nezvishoma mumatope mugodhi torque, ari optimum simba chinhu, etc.
