I-seri ye-PI-CKSG yenkqubo yokulungisa irekhitha

I-reactors ye-seri ye-PI-CKSG yinto eculawulekileyo kuzo zonke izinhlobo zokulungisa imvume. Iyakhiswe ngokulandelana kwi-circuit ye-capacitor ukuthwasa ukuphakama kwe-harmonics bese iyathwasa i-parallel resonance, okuyakunika ukuthuthukiswa kwezicapacitor ne-grid yamandla.

Isimo sokusebenza: GB/T 1094.6-2011 I-reactors.

Umcubuko wokuhlanjwa, ukunyuka okuncane kwezulu, iphumo elincane, ukungena kweharmoniki phezulu, ubunzima obungqondile ukungena kwezinto ezingenakho ukungena kwezulu, isebenza ngokushesha, ukufakwa kungenzeka, amaphesenti esibhedlela, ubude bokusebenza ngeminyaka engapheli, noma kunezimali zokukhuseleka izulu.

Izikhululo zihlukaniswa ngemibili: amathathu amathathu kanye namathathu asikhombisa. Zombili ziyagcwa ngokushushu noma nangemikhombiso. Phakathi kazo, izikhululo zemathathu amathathu zinamakhapacithela azo akhohlo aqondile, aze izikhululo zemathathu asikhombisa angakhohliwa ngamakhapacithela amakhohlwano.

Imikhombiso yenkile yamade amaphetheni amancane, amancane angaphethelwa ngokugcwele. Imikhombiso yenkile iyahlukaniswa ngeminye amacala amaningi. Amacala ahlanjwe ngamaphoyinti amakhohlwano angaphethelwa ngokugcwele. Amaphoyinti ahlanjwe ngamaphetheni amakhohlwano angaphethelwa ngokugcwele aze ayivikele ukuthi amacala engavutshelwa lapho isikhululo senzekile.

Isikhwama kubekwe ngokwehliswa weqile laseH, kuhlanganiswa kanengi futhi kuhlelwe ngokulinganile, akukho inkanyezi yaseleyo kwenqo. Inobukhona obuhle futhi kunezindlela eziphambene nezindlela zokulula.

Emva kokuthi isikhwama nekankane yereyitha zibe yisikhathi esisodwa, zilandela inqubo yokuqina ngaphambili - ukulaywa kwevakwam - ukupheka ngokushesha. Isikhwama sevakwam sokulaywa seH-grade sisebenziswa ukuthi sihlakaniphile isikhwama nekankane yereyitha. Lokhu kungcinywa kakhulu ingxenye yengciko emva kokusebenza, futhi inobukhona obukhulu bendawo yokulula, uyisela ukuthi ireyitha ingasebenze ngokuphelele futhi ingavamale futhi noma kuzindlela ezikhulu zokulula.

Izinto zokuxhuma ezisematheni asikankane yereyitha zinhlanzi yezinto engenamandla ukuthi asegwule ukuthi ireyitha inobungo obukhulu bendawo kanye nobukhona obuphansi bendawo yokulula, ukuze asegwule ukuthi kunezindlela eziphambene nezindlela zokulula.

Imigqa yokubamba ivamele inqubo yokugcina ngokushesha yezinkwe, ukuthi kugcinwe ukuxhumana okuphelele.

Kunamalunga nezinhloso zokudonsela, lokhu kweyishishini inobukhulu obuncane, ubunzima obuncane futhi inobuso obuhle.

Qaphela ukuthi ivoli Uc yekhaphasithela iyaphakama emva kokuthi kweyishishini ikhanyekile.

Uc=Uo/(1 - P) : Uo: Ivolthi yisithemba, P: isithathu sokuxhumana kweyishishini.

• Iziqiniso zokushisa

Ukulineya kwe-rektatha L > 0.95, futhi kungena ku-1lin=1.2*(11+13+15+17……)

Uma ukuningi kwe-harmonics kwezinhlobo zokuxazulwa zokushisa zokuthiwa ngendlela yo-ENV 61000—2—2 isetshenziswa njengesbongo sokulinganisa, kepha U3=0.5%; U5=6%; U7=5%, U11=3.5%; U13=3%. Uma kudingekile, izi-rektatha ezingenakho okusha kudala, isb. okunye Un, fn, Qc, P% amanani futhi nezinguquko eziphezulu kuno-standards.

• Ukukhetha kwe-Tuning (Detuning) i-Order ye-Harmonics

I-tuning harmonic fr iyisisekelo esihlanganisa nge-frequency yokuqeda kwe-L—C isandisa, fr=1/2Π√(lc), lapho n iyinkimbetho ye-harmonic. Isibonelo, kumgwa wama-50Hz, n=fr/50, okubalulekile kusebenzwa ngu-7% (5-7th order), 14% (3rd order). Kufanele fr libonise ukuthi inkimbetho yamanani e-harmonics ayaphandle kwe-frenquency yokuqeda futhi libonise ukuthi awukho ukungcola kwezinye izinhlobo zokontrola.

• Ukukhetha kweqoqo futhi ukuvikela izikhathi

Ukufaka kwezindawo zokulandelana

a) Kugqamisa esibeni

b) Kugqamisa ngebanki yamacala, kuyindlela engcono ukuthi ikhwe ngokweqile noma ukuthi ikhwe phezulu kwamacala. Indawo ekugqamiswe ngayo imbanki yamacala kufanele ikhankanye ukuvikela amagugu.

Indlela yokufaka: 2×25Kvar + 4×50Kvar

★Iqondo lezindawo zokulandelana: Ukuvikela okwenziwe ngokuvamile Ps-2×200 + 4×320=1680W F=0.3×Ps=0.3×1680=504m³/h

★Iqondo lebanki yamacala: Ukuvikela okwenziwe ngokuvamile (igqamisi: 800×1000×2200) Ubungako bokuvikela: 0.75×250=187.5m³/h

Ukulandelana nokugcinwa
Xa kulandelwa irekthaya, kufanele ikhokwe ngokuphawuliwe kwezokwelapha ngokwengeziwe. Uma lokhu akukwazi ukwenziwa, izirekthi kufanele zithathwe emhlabeni omkhulu noma emhlabeni wekhaperi enkuku, futhi izinto eziphakeme kufanele zilaywe phakathi kwamarekthi futhi phakathi kwamarekthi nezinyawo zangaphakathi zemhlabu ukuvikela ukuthi zingakhombane.
Xa kusekelwa irekthaya, akukwamki ukuthi kwenzekelwe ukugcina kwezinsulatholi futhi kwezinyawo zemhlabu, futhi kufanele usekelwe ngokuthula. Izirekthi kufanele ugcinwe endaweni ethuthile engenazo imikhawulo ye-gasi, futhi kufanele uvikele ukuthi amathuba asingena kurekthaya. Lokhu kufanele kuqondwe futhi xa irekthaya ithuliwe ukuphawuliwe.
Ngathimba lokulandelana nokugcinwa, izirekthi zifanele zibe yimigqa zokulayishwa ngezinsulatholi ziyephezulu. Akuvunyelwe ukuthi irekthaya zilaywe ezinye zilandelayo ngaphansi ngenye into.
Ukuvunyelwa ngumsebenzisi
Emva kokuthola irektho, umsebenzisi kufanele kuqaphele okokuqala ukuthi i-model specification nezinhlobo ezivulekile kwi-nameplate ziyafanaye nezokuthengwa. Nokunye, kuqaphele ukuthi kungaphawuliwe kakhulu kwalokho irektho, amagqambo, amakhethi wokuvunyelwa njalo.
Umsebenzisi kufanele akwenze ukulungiswa kwokwenza imviyelo ngokushaywa kwe-rektho ngokulinganisa kwezinkumbulo ezingama-75% yesivuno sentaba. Isikhathi sokulungiswa kwezinkumbulo singama-10 sec, futhi inani lokulungiswa kufanele libe yisidingo sababili.
"Qala"
Wonke amawiri kufanele ayanelise kakhulu kwaye kufanele kwenziwe ukulungiswa ngalo kabili ngokudlule kwezinyanga ezisix. Nokunye, indawo yokuphakama kwamawiri kufanele iyanele.
Ukuphepha kwezindleko kufanele kuhlanganise ngokuphelele ukusebenza njengokuphepha.
