Kodi choyambira chofewa cha solid state ndi chiyani?

Choyambitsa chofewa cha solid state ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kuwongolera magetsi omwe amagwiritsidwa ntchito pa mota ya AC panthawi yoyambitsa. Pogwiritsa ntchito thyristors (SCRs) kapena zida zina za semiconductor, zoyambitsa zofewa zimachepetsa mphamvu yoyambira yolowera ndikuchepetsa kupsinjika kwa makina pa mota ndi zida zolumikizira. Zinthu zazikulu za zoyambitsa zofewa za solid-state ndi izi: choyambitsa chofewa chimatenga malo ochepa kuposa njira zachikhalidwe zoyambira monga autotransformers. Ubwino wa zoyambitsa zofewa za solid state ndi monga: magetsi a mota amawonjezeka pang'onopang'ono pakapita nthawi yodziwika. Ma profiles oyambira omwe angasinthidwe: Ogwiritsa ntchito amatha kusintha magawo monga nthawi yokwera ndi torque yoyambira. Ntchito yoteteza: Zoyambitsa zofewa nthawi zambiri zimakhala ndi Chitetezo Chodzaza Zinthu, kuyang'anira kusalinganika kwa gawo ndi chitetezo cha undervoltage. Kapangidwe kakang'ono: Zoyambira zofewa zimatenga malo ochepa poyerekeza ndi njira zachikhalidwe zoyambira monga autotransformers. Ubwino wa zoyambira zofewa zokhazikika
1. Kuchepetsa kupsinjika kwa makina (mwachindunji) kungayambitse kukwera kwa mphamvu mwadzidzidzi, zomwe zingayambitse kuwonongeka kwa injini ndi zida zoyendetsedwa. Zoyambira zofewa zimachepetsa kukwera kumeneku ndikuwonjezera moyo wa zida zamakina.
2. Mphamvu yolowera kwambiri ikayamba mwachindunji imatha kusokoneza netiweki yamagetsi, zomwe zingayambitse kuchepa kwa magetsi ndikukhudza zida zina. Choyambira chofewa chimachepetsa kwambiri mafunde awa, ndikuwonetsetsa kuti magetsi akuyenda bwino.
3. Ngakhale kuti zoyambira zofewa zimapangidwa makamaka kuti zigwiritsidwe ntchito poyambira ndi kuzimitsa, kuthekera kwawo kuchepetsa kutayika panthawiyi kumathandiza kuti dongosolo lonse ligwire bwino ntchito.
4. Kudalirika kwabwino kwa makina Ndi chitetezo chophatikizidwa, zoyambira zofewa zimawonjezera kudalirika kwa makina a injini popewa kuwonongeka chifukwa cha kulephera kwa magetsi kapena zinthu zodzaza kwambiri. Zoyambira zofewa zokhazikika zimakhala zothandiza makamaka m'mafakitale komwe ma mota amphamvu komanso apakati (nthawi zambiri 2.3 kV mpaka 13.8 kV) amayendetsa katundu wambiri, monga: mafuta ndi gasi: ma compressor, mapampu, ndi mafani. Kukumba: Mphero zamagetsi zama conveyor, ma crushers ndi kugaya.

Madzi ndi madzi otayira: a mapampu akuluakulu ndi ma blowers.
Kupanga magetsi: Kumagwiritsidwa ntchito poyang'anira zida zothandizira monga mapampu odyetsa chakudya ndi mafani a nsanja yoziziritsira.
Mavuto ndi zinthu zomwe muyenera kuganizira
Gawo 1 Chotsani kutentha
Zipangizo zofewa zoyambira zimapanga kutentha panthawi yogwira ntchito, makamaka pakugwiritsa ntchito mphamvu yapakati komanso yapamwamba. Mpweya wabwino kapena makina ozizira ndi ofunikira.

2. Kuchepa kwa kuthamanga kwa magazi
Kutsika kwa magetsi koyambirira kumakhudza ntchito zodziwikiratu. Kusintha ndi kuphatikiza koyenera ndikofunikira kuti magwiridwe antchito oyambira agwirizane ndi zofunikira za makina.

3. Mtengo
Zoyambira zofewa za Solid state zitha kukhala zodula kwambiri poyambirira poyerekeza ndi njira zina zoyambira. Komabe, zabwino zawo zanthawi yayitali nthawi zambiri zimayimira ndalama zomwe zayikidwa. Pomaliza Zoyambira zofewa za Solid state ndi gawo lofunikira la makina amagetsi apakati ndi okwera kwambiri a AC, zomwe zingapereke kuyambika kosalala, kuthamanga pang'ono komanso kugwira ntchito bwino kwambiri. Kutha kwawo kuzolowera zosowa zosiyanasiyana zamafakitale kumawapangitsa kukhala chida chofunikira kwambiri chowongolera magwiridwe antchito a injini ndikuwonjezera moyo wa zida. Pamene ukadaulo ukupita patsogolo, kuphatikiza ntchito zanzeru, monga kulumikizana kwa iot ndi kukonza zinthu zodziwikiratu, kudzawonjezera luso lawo, kuwapangitsa kukhala ofunikira kwambiri m'mafakitale amakono.
