Umgaqo wokusebenza we-2021 entsha yokunyibilikisa iziko

1. Ukusuka kumzobo weskim wesekethe engundoqo ye ukuchithwa kwesithando somlilo ngaphezulu, kunokubonwa ukuba icandelo lokubonelela ngombane kwiziko lokunyibilikisa iziko lenziwa ngesixhobo sokudibanisa amandla kunye nokufakwa kwe-AC kwinqanaba elithathu; Icandelo lokulungisa lenziwe ngezigaba ezithathu ezilawulwa ngokupheleleyo zebhulorho eyakhiwe ngee-thyristors ezininzi. Xa ivaliwe okanye isilele kwaye iyekile ukusebenza, isilungisi sinokuguqulwa ukusuka kwimeko yokusebenza yomlungisi ukuya kwimeko yokusebenza ye-inverter, ukuze igcinwe ikakhulu kwi-DC Amandla kwisekethe ephakathi aphinda abuyiselwe kwinethiwekhi yokuhambisa umbane. Ukukhusela i-thyristor yokulungisa kwakhona, i-fuse ekhawulezileyo kunye ne-DC yokukhuseleka kwendlela yokubaleka ikwaseta kwisekethe.

Isiphaluka esiphakathi seDC ngokuyinxalenye senziwe ngokudinwa okupholileyo ngamanzi kunye nomxholo wentsimbi. Umsebenzi wayo kukucoca ukuphuma kwe-DC kwesilungiso kunye nokucinezela ifuthe lamaza ombane aphakathi kwigridi yamandla. Xa umthwalo ufutshane-ikwajikeleza, ikwadlala indima kuthintelo lwangoku ukuba lukhule ngokukhawuleza okukhulu.

I-inverter yenziwe ngesigaba esinye sokulawula ngokupheleleyo inverter ibhulorho eyenziwe zii-thyristors ezininzi ezikhawulezayo. Ngokunyanzelisa i-thyristors, ikhoyo ngoku ikhupha iitheminali zokufaka kunye no-v zomthwalo ofanayo wokuphinda-phinda kwicala elitshintshayo kwinqanaba eliphakathi.

Ukongeza, isekethe ephambili yokunyibilikisa iziko kukwabandakanya ii-AC kunye neDC ukuqala kweesekethe.

2. Ulawulo lweesekethe

Isekethe kumzobo ophambili wesekethe yolawulo lwesekethe yokunyibilikisa iziko. Kule nxalenye, ulawulo oluneenkcukacha ngakumbi kunye nohlengahlengiso lwebhlogramu inikezelwa. Kuyabonakala kumfanekiso ukuba isilungisi somlilo esinyibilikayo silawulwa ziiyunithi ezimbini: umlawuli wokulungisa kunye nomlungisi wokulungisa. Uguquko lwe-pulse amplifier yokulawula.

Ukubeka iliso kwimpazamo kunye nokukhuselwa kwento yonke yokunyibilikisa iziko kulawulwa kukhuseleko lwe-elektroniki kunye nokujonga esweni, kwaye imiqondiso yangoku kunye nevolthi igqityiwe ngokukodwa yibhodi yempendulo yomqondiso.

Ukuqala kweziko lonke lokunyibilikisa iziko kugqitywa ngolawulo lokungcangcazela.

Ukulungelelaniswa kwazo zonke iiyunithi ezingentla kulawulwa ngumlawuli onokucwangciswa (i-PLC).
