Isethulo Sezinto Ezisetshenziswa Kakhulu Ezisebenza Kakhulu Emashubhu Evacuum

Eminyakeni engu-20 edlule, imithombo yamandla avela imvamisa ephezulu(evame ukwaziwa ngokuthi "izithando zomlilo ezinemvamisa ephezulu") ezisetshenziselwa ukushisela amapayipi kanye nokwelapha ukushisa e-China ikakhulukazi kwakuyimishini enamashubhu kagesi (aziwa nangokuthi "amashubhu e-vacuum") njengezingxenye eziyinhloko ze-inverter. Isimiso esiyisisekelo siboniswa esithombeni esilandelayo:

I-AC yezimboni ezijwayelekile(izintambo ezine zesigaba sesithathu ezingu-380V/50HZ e-China) iguqulelwa ku-AC elungisekayo ukusuka ku-0 kuye ku-380V(imvamisa engashintshiwe) ngesilawuli sikagesi se-thyristor AC, bese yenyuka ifinyelela cishe ku-10000V kagesi aphezulu(imvamisa engashintshiwe, i-voltage ephezulu ayishintshiwe, bese iphinda iguqule amandla kagesi ayishumi) izinkulungwane zamandla kagesi aphezulu e-DC, bese i-oscilled ngeshubhu ye-vacuum iye ku-HF ne-HV yamanje, bese ngokusebenzisa i-LC parallel resonance ukuze kukhuliswe i-oscillating current, nangemva kokunikezwa kokunciphisa ugesi ku-inductor esetshenziselwa ukushisisa amapayipi ensimbi nezinye izinto zokusebenza njll.

Inhloso yokulawula i-voltage ye-AC iwukulungisa amandla okufaka nawokukhipha ukuze ahlangabezane nezidingo zokusebenza, futhi lapho kulungiswa i-voltage nayo idinga ukwenza i-voltage iqine ukuze kuqinisekiswe ukuqina kwamandla okukhipha impahla ngaphansi kwezimo ezithile zokusebenza.

Ngenxa yokusetshenziswa kwe-vacuum tube (izingxenye ezincane zamanje zamandla kagesi aphezulu), i-voltage kumele inyuswe noma ingakwazi ukukhipha amandla amakhulu, kodwa ngasikhathi sinye, ukuze uvumelane nokuvinjwa okuncane kwe-inductor, kuyadingeka ukunciphisa ugesi.

Izithombe ezingezansi ziyi-600KW single-loop vacuum tube high frequency kanye ne-100KW triple circuit vacuum tube okokusebenza kwe-HF yokucisha.

Embonini yokushisela amapayipi, kusenenani elincane lamashubhu evacuum aphezulu, kuyilapho emikhakheni efana nokucisha nokugqama, amashubhu evacuum aphezulu asasetshenziswa kabanzi.
