Nzira shanu dzakajairika dzekugadzirisa matambudziko ekuisa induction kunyungudutsa mavira

(1) Simba rekupa induction melting furnace: Shandisa multimeter kuti uone kana kune magetsi kuseri kweiyo main circuit switch (contactor) uye fuse yekudzora, iyo inobvisa mukana wekubviswa kwezvikamu izvi.

(2) Rectifier of induction melting furnace: Iyo inogadzirisa inoshandisa matatu-chikamu chakanyatsodzora bhiriji rectifier wedunhu, iyo inosanganisira matanhatu anokurumidza fuse, matanhatu thyristors, matanhatu pulse transformers uye freewheeling diode.

Pane chiratidzo chitsvuku pane inokurumidza-kuita fuse. Kazhinji, chiratidzo chinodzoserwa mukati megoko. Kana iyo yekukurumidza-kuita ichivhuvhuta, inobuda. Zvimwe zviratidzo zvinokurumidza kuita zvakasimba. Kana iyo yekukurumidza-kuita ichivhuvhuta, inonamira mukati. , Saka nekuda kwekuvimbika, unogona kushandisa multimeter kuti uedze kukurumidza-kuvhuvhuta pa / off gear kuti uone kana inoputika.

Nzira iri nyore yekuyera thyristor ndeye kushandisa multimeter kuyera cathode-anode yayo uye gedhi-cathode kuramba ne multimeter (200Ω block). Iyo thyristor haidi kubviswa panguva yekuyera. Mumamiriro ezvinhu akajairwa, anode-cathode kuramba kunofanirwa kuve kusingagumi, uye gedhi-cathode kuramba kunofanirwa kunge kuri pakati pe10-50Ω. Yakakura kwazvo kana diki inoratidza kuti gedhi reiyi thyristor rinokundikana, uye harigone kukonzeresa kuitisa.

Rutivi rwechipiri rwepulse transformer rwakabatana kune thyristor, uye rutivi rwekutanga rwakabatana nebhodhi guru rekutonga. Shandisa multimeter kuyera kupikisa kwekutanga kwe50Ω. Iyo freewheeling diode haiwanzo kutadza. Shandisa multimeter diode kuyera magumo ayo maviri panguva yekuongorora. Iyo multimeter inoratidza kuti junction voltage inodonha inenge 500mV munzira yekumberi, uye reverse direction yakavharwa.

(3) Inverter ye induction melting furnace: Inverter inosanganisira mana anokurumidza thyristors uye ina pulse transformers, iyo inogona kuongororwa maererano nepamusoro nzira.

(4) Transformers ye induction yakanyunguduka choto: Imwe neimwe mhepo yetransformer yega yega inofanirwa kubatana. Kazhinji, kushorwa kwechikamu chekutanga kunosvika makumi emakumi, uye yechipiri kuramba ishoma ohms. Izvo zvinofanirwa kucherechedzwa kuti chikamu chekutanga chepakati frequency voltage transformer yakabatana mukuwirirana nemutoro, saka kukosha kwayo kwekudzivirira i zero.

(5) Capacitors of induction melting furnaces: Iwo magetsi ekupisa capacitors akabatanidzwa mukufanana nemutoro anogona kuputsika. Iwo ma capacitor anowanzo kuiswa mumapoka pane capacitor rack. Iro boka revakaputsika capacitors rinofanirwa kugadziriswa kutanga panguva yekuongorora. Bvisa nzvimbo yekubatanidza pakati pebhawa yebhasi yeboka rimwe nerimwe rema capacitor uye bhawa guru rebhazi, uye kuyera kupokana pakati pemabhazi maviri eboka rimwe nerimwe re capacitor. Kazhinji, inofanira kunge isingagumi. Mushure mekusimbisa boka rakashata, bvisa ganda rakapfava remhangura yega yega yemagetsi inopisa capacitor inotungamira kubhawa yebhazi, uye tarisa imwe neimwe kuti uwane yakaputsika capacitor. Imwe neimwe yemagetsi inodziya capacitor inoumbwa nemakumbo mana. Iyo goko idanda rimwe, uye imwe danda inotungamirwa kune yekupedzisira cap kuburikidza nemainsulators mana. Kazhinji, musimboti mumwe chete ndiwo uchaputswa. Iyo capacitor inogona kuramba ichishandiswa, uye huwandu hwayo ndeye 3/4 yepakutanga. Imwe mhosva ye capacitor ndeyekudonha kwemafuta, izvo zvisingawanzo kukanganisa kushandiswa, asi teerera kudzivirira moto.
