Mhando iyi yemidziyo inosanganisira masimbi ekupikisa, tembiricha yekugadzirisa midziyo, etc. Iyo wire-ronda rekudzivirira zvinhu zvinoshandiswa mumagetsi ekupisa element mutoro zvinogona kusvika 1.4 nguva yakatarwa ikozvino. Kana kuwedzera kwemagetsi emagetsi kunofungidzirwa, ikozvino inowedzera. Ikozvino kushanduka kwemhando yerudzi urwu rwemutoro idiki kwazvo, ndeye AC-1 zvinoenderana nechikamu chekushandisa, uye mashandiro acho haawanzo. Paunenge uchisarudza contactor, zvinongodiwa chete kuita iyo yakatemerwa inoshanda ikozvino Ith yeiyo contactor yakaenzana kana yakakura kupfuura 1.2 nguva yekushanda ikozvino yemagetsi ekupisa midziyo.
3.2 Kusarudzwa kwevanobatisa kudzora mwenje wemagetsi
Kune marudzi mazhinji emidziyo yekuvhenekesa, uye marudzi akasiyana emidziyo yekuvhenekesa ane akasiyana ekutanga ikozvino uye ekutanga nguva. Chikamu chekushandisa cherudzi urwu rwemutoro ndeye AC-5a kana AC-5b. Kana nguva yekutanga-yakanyanya kupfupika, kupisa ikozvino Ith inogona kusarudzwa kuti ive yakaenzana ne1.1 nguva yekushanda ikozvino kwemagetsi ekuvhenekera. Nguva yekutanga-yakareba uye simba rekuita rakaderera, uye kupisa kwaro ikozvino Ith inogona kusarudzwa kuti ive yakakura kudarika ikozvino kushanda kwemagetsi ekuvhenekera. Tafura 2 inoratidza kusarudzwa kwemisimboti yevanobatika kune akasiyana mwenje michina.

3.3 Kusarudzwa kwemacontactor ekudzora emagetsi welding transformers
Kana iyo yakaderera-voltage transformer mutoro yakabatana, iyo transformer ichava nenguva pfupi yakakwira yakakwira ikozvino nekuda kweiyo pfupi-circuit ye electrode parutivi rwechipiri, uye yakakura ikozvino ichaonekwa parutivi rwekutanga, iyo inogona kusvika 15 kusvika ku20 nguva yakatarwa ikozvino. zvine chekuita nehunhu hwepakati.Apo muchina wemagetsi welding unowanzo gadzira kamwe kamwe simba razvino, switch padivi pekutanga retransformer.
> Pasi pekunetseka kukuru uye ikozvino, iyo contactor inofanira kusarudzwa maererano nepfupi-circuit ikozvino uye welding frequency yedivi rekutanga apo ma electrode ari mapfupi-anotenderera pasi pesimba rakarongwa re transformer, ndiko kuti, kuchinja ikozvino kwakakura kudarika. the primary-side current kana rutivi rwechipiri rwuri pfupi-circuited. Chikamu chekushandiswa kwemitoro yakadaro ndeye AC-6a.
3.4 Kusarudzwa kwemota contactor
Motor contactors vanogona kusarudza AC-2 kusvika 4 zvinoenderana nekushandiswa kwemota uye rudzi rwemota. Kune yekutanga ikozvino pa6 nguva yakatarwa ikozvino uye inoputika ikozvino pane yakarongwa ikozvino, AC-3 inogona kushandiswa. Semuenzaniso, mafeni, mapombi, nezvimwewo, anogona kushandisa tafura yekutarisa Nzira uye yakasarudzwa curve nzira inosarudzwa maererano nemuenzaniso uye bhuku, uye hapana kumwe kuverenga kunodiwa.
Ikozvino inomonereka uye kupwanya kwemota yeronda zvese zviri zviviri 2.5 times the rated current. Kazhinji, kana uchitanga, resistor yakabatana munhevedzano ne rotor kudzikamisa yekutanga ikozvino uye kuwedzera yekutanga torque. The kushandiswa chikwata AC-2, uye rotary contactor anogona kusarudzwa.
Kana mota ichimhanya, ichimhanya ichidzokera kumashure uye ichibhureki, yakabatana ikozvino ndeye 6Ie, uye chikamu chekushandisa iAC-4, iyo yakanyanya kuomarara kupfuura AC-3. Motokari magetsi inogona kuverengerwa kubva kumagetsi akanyorwa pasi peUtilization Category AC-4. Iyo formula ndeyotevera:
Pe=3UeIeCOS￠η,
Ue: mota yakayerwa ikozvino, kureva: mota yakayerwa voltage, COS￠: simba chinhu, η: mota inoshanda.
Kana hupenyu hwekubatana huchibvumirwa kuva hupfupi, iyo AC-4 ikozvino inogona kuwedzerwa zvakakodzera, uye inogona kuchinjwa kuva AC-3 pane yakaderera zvikuru pa-off frequency.
Zvinoenderana nezvinodiwa zvekuchengetedza mota kurongeka, iyo iripo pazasi yakakiyiwa-rotor ikozvino inofanirwa kubatanidzwa uye kuputswa nedhizaini yekudzora. Iyo yakakiyiwa-rotor ikozvino yeakawanda Y akateedzana motors ndeye ≤7Ie, saka kuvhura nekuvhara kukiyiwa-rotor ikozvino kunofanirwa kutariswa kana uchisarudza contactor. The specification inotaura kuti kana mota ichimhanya pasi pe AC-3 uye rated current yecontactor haina kukura kudarika 630A, contactor inofanira kukwanisa kushingirira ka8 pane yakayerwa ikozvino kwemasekonzi gumi.
Kune majekiseni emagetsi emagetsi, iyo inoshanda ikozvino ishoma pane yakayerwa ikozvino, kunyangwe iyo yekutanga ikozvino inosvika 4 kusvika 7 nguva yakatarwa ikozvino, asi nguva ipfupi, uye kukuvadzwa kwevanobatika kweiyo contactor hakusi kukuru. Ichi chinhu chakatariswa mukugadzirwa kweiyo contactor, uye kazhinji inosarudzwa Iyo yekubata yekubata inofanirwa kuve yakakura kupfuura 1.25 times iyo yakayerwa kugona kwemota. Kune mota dzinoshanda pasi pemamiriro akakosha, inofanirwa kutariswa zvinoenderana nemamiriro chaiwo ekushanda. Semuyenzaniso, chikwiriso chemagetsi ndechemutoro unorema, mutoro unorema unotanga uye unomira kazhinji, reverse connection braking, etc., saka kuverenga kwekushanda ikozvino kunofanirwa kuwanzwa neakawanda anoenderana, nekuti mutoro unorema unotanga uye unomira kazhinji. , sarudza 4 nguva iyo yakarongerwa ikozvino yemotokari, kazhinji reverse connection pasi pemutoro unorema Iyo braking current inopeta kaviri yekutanga ikozvino, saka 8 nguva iyo yakatarwa ikozvino inofanira kusarudzwa nokuda kwechiitiko ichi chekushanda.
