Kuyamba kofewa kwa mota ya AC yamagetsi apakati komanso okwera

Zinthu zazikulu:

Pogwiritsa ntchito microprocessor ya digito kuyang'anira deta ndi kulumikizana, pogwiritsa ntchito ukadaulo wowongolera chizindikiro ndi ukadaulo wodzipatula, dongosololi lili ndi mphamvu yolimbana ndi kusokoneza. Ndipo kuwongolera zida ndi nthawi yeniyeni, kogwira ntchito bwino, kokhazikika komanso kodalirika. Ukadaulo wapamwamba wowongolera kutumiza kwa ulusi wa kuwala umagwiritsidwa ntchito kuzindikira choyambitsa ndi kuzindikira thyristor yamagetsi okwera, komanso kudzipatula kotetezeka pakati pa ma circuits owongolera okwera ndi otsika. Ukadaulo wodzipatula wamagetsi okwera pafupipafupi komanso wotumizira umagwiritsidwa ntchito kupereka magetsi otetezeka komanso odalirika pazida zamagetsi zomwe zimagwira ntchito mu gawo lamagetsi okwera. Ukadaulo woyamwa wamagetsi osasunthika komanso wamphamvu wa netiweki ya capacitor yotsutsa umatsimikizira kugwira ntchito kodalirika komanso kotetezeka kwa zida zamagetsi zotsatizana pansi pamagetsi okwera. Pogwiritsa ntchito ukadaulo wamagetsi wa EVT (Electronic voltage Transformer), kutumiza kwa ulusi wamagetsi popanda kusokoneza, kusintha kwa gawo. Ma curve asanu ndi limodzi oyambira, osinthika ndi mawonekedwe amakina ndi zofunikira zamakina osiyanasiyana amagetsi, amasinthira yokha torque yayikulu yamagetsi ma curve asanu ndi limodzi kuti agwirizane ndi mawonekedwe osiyanasiyana amakina a katundu, ndi ntchito yomaliza yosinthika ya torque, amaletsa bwino zotsatira za nyundo yamadzi zomwe zimachitika chifukwa cha kutsekedwa kwa katundu wa pampu. Yoyenera machitidwe amphamvu olimba. ● Ntchito zoteteza kwathunthu: overvoltage, undervoltage, angapo Chitetezo Chodzaza Zinthu ma curve, komanso mdima, kusweka kwa gawo, kusalinganika, cholakwika cha gawo, chitetezo cha zero sequence grounding, kutentha kwambiri kwa thyristor, nthawi yayitali yoyambira, malire oyambira, chitetezo cha thyristor cholakwika, ndi zina zotero. Kabati yoyambira yolimba ya SHMV-DN yamphamvu kwambiri imatha kuyerekezeredwa pogwiritsa ntchito mota yamagetsi otsika (380V) isanayambe kugwira ntchito yamagetsi okwera pamalopo kuti ipereke zambiri zaukadaulo ndi chitsimikizo cha ntchito yovomerezeka. Kabatiyo imagwiritsa ntchito kapangidwe ka KYN28A-12 ndi mbale ya aluminiyamu, yomwe ili ndi ubwino wokana dzimbiri, kukana okosijeni, kapangidwe katsopano kakunja, mawonekedwe okongola, komanso mulingo woteteza kwambiri. Itha kuphatikizidwa mosavuta ndi kabati yoyambira ya KYN28A-12. Pankhani yamagetsi a jenereta, pali pulogalamu yapadera yowongolera, yomwe ingayambe bwino ngati magetsi, magetsi ndi ma frequency osakhazikika. ● Ntchito yosinthira magawo awiri: pa mota ya liwiro la awiri, kapena pankhani ya magetsi ochokera ku gridi/jenereta, kapena pa kuthamanga kamodzi kapena kawiri, magawo a ma mota awiriwa ndi osiyana, magawo awiri a magawo oyambira ndi oyimitsa akhoza kulowetsedwa, ndipo magawo ofunikira amatha kubwezedwa mosavuta kudzera pa terminal yokonzedwa kuti ayambire ndikuyendetsa. ● Mawonekedwe abwino a makina a munthu, ziwerengero zakale za deta ndi mafunso. Ngati kuli kofunikira, mawonekedwe a pazenera logwira akhoza kuwonjezedwa kuti pakhale kusinthana kwabwino kwa chidziwitso cha anthu ndi makina. Yokhala ndi mawonekedwe a RS485 ndi njira yolumikizirana yosankha (Modbus/Pro bus), kuyang'anira koyenera kwapakati.
