Ingemuva lephrojekthi
Indawo yeRizhao Workers' Cultural Palace isenyakatho yomgwaqo uShandong, entshonalanga yomgwaqo uHuancui, naseningizimu yomgwaqo uXuegeng, ehlanganisa indawo engamamitha-skwele ayi-14496.7, enendawo yonke yokwakha engamamitha-skwele angama-25878.21.Imisebenzi eyinhloko nezinsiza zihlanganisa: isikhungo sokuqeqesha amakhono abasebenzi, isikhungo somsebenzi wamasiko, isikhungo semidlalo yabasebenzi, kanye nesikhungo sesevisi yabasebenzi.Ngemva kokuphothulwa, izoba yindawo yenhlalakahle yomphakathi ephelele yawo wonke amazinga abasebenzi edolobheni, ehlanganisa isiko nobuciko, ezemidlalo nokuqina, imfundo nokuqeqeshwa, imibukiso nokubukisa, kanye nezinsizakalo zezisebenzi.
I-Rizhao Workers' Cultural Palace iyingxenye ebalulekile yesistimu yesevisi yamasiko yomphakathi yedolobha kanye nephrojekthi yokuziphilisa ehlomulisa abasebenzi futhi ithuthukise ikhwalithi yedolobha.I-Rizhao Federation of Trade Unions, "njengomndeni kamama" wabasebenzi edolobheni, ihlose ukudala indawo evulekile yesevisi ebanzi ehlanganisa imisebenzi yemfundo nokuqeqeshwa kwabasebenzi, ukushintshana kwamasiko, ezemidlalo nokuqina, isisebenzi esiyimodeli kanye nesibonisi somoya wengcweti, isisebenzi. isevisi kanye nokufunda kwasemadolobheni, ukuze iningi labasebenzi likwazi ukuzwa imfudumalo namandla enhlangano yezinyunyana ngebanga elinguziro, isevisi ecabangelayo nengokoqobo yenhlangano yezinyunyana.
Isicelo somkhiqizo
Le phrojekthi yamukela ukulawulwa kwe-harmonic yenkampani yethu kanye nemikhiqizo yesinxephezelo esisebenzayo, okuhlanganisa imojuli yesihlungi esebenzayo ye-APF, i-capacitor evamile, i-switch eyinhlanganisela, i-reactor, isilawuli, njll. Isetshenziselwa ngokuyinhloko ukulawula okuvumelanayo kanye nesinxephezelo samandla asebenzayo.Ingathuthukisa ngempumelelo isici samandla, inciphise ukulahlekelwa futhi iqinisekise ukusebenza okuzinzile nokuthembekile kwemishini yamandla ngenkathi ihlunga i-harmonic.
Izinzuzo zemikhiqizo yokuhlunga esebenzayo
Isinxephezelo se-1.Harmonic: I-APF ingahlunga ama-harmonics angu-2 ~ 50 ngesikhathi esifanayo
2.Isinxephezelo esisebenzayo: i-capacitive inductive (- 1~1) isinxephezelo esingenasinyathelo
3.Ukusabela okusheshayo kanye nokwelashwa okusheshayo
4.Impilo yokuklama ingaphezu kwamahora angu-100000 (ngaphezu kweminyaka eyishumi)
Isihlungi esisebenzayo se-HYAPF sibona umthwalo wamanje ngesikhathi sangempela nge-CT transformer yamanje yangaphandle, sikhipha ingxenye ye-harmonic yomthwalo wamanje ngokubala kwangaphakathi kwe-DSP, bese sithumela isignali ye-PWM ku-IGBT yangaphakathi ukuze ilawule isiguquli ukuze sikhiqize okwamanje. ilingana ne-harmonic yomthwalo futhi iphikisana nendawo bese uyijova kugridi yamandla ukuze unxephezele i-harmonic current, uqaphela umsebenzi wokuhlunga.
Izinzuzo zomkhiqizo
1.Yenza isinxephezelo samandla asebenzayo njengoba kudingeka ukuze uthuthukise isici samandla
I-2.I-capacitor yamandla ene-voltage ephezulu elinganiselwe
3.I-Reactor enokwethenjelwa okuphezulu kanye nokusetshenziswa kwamandla okuphansi
I-4.Ukufakwa kanye nezesekeli zokuzikhethela kukhabhinethi zizimele kakhulu
Lapho i-CKSG yochungechunge lwezigaba ezintathu zochungechunge lwezihlungi eziphendulayo zisetshenziselwa ukunxephezela amandla asebenzayo e-capacitive, zivame ukuthintwa i-harmonic current, i-inrush current evalayo kanye nokushintshwa kwe-overvoltage, okuholela ekulimaleni kwe-capacitor nokunciphisa isici samandla.Ngakho-ke, ama-reactors okuhlunga ezigaba ezintathu adinga ukufakwa ngaphambili ekugcineni kwama-capacitor ukuze acindezele futhi amunce ama-harmonic, avikele ama-capacitor, agweme umthelela we-harmonic voltage yamanje kanye ne-impulse voltage yamanje, athuthukise ikhwalithi yamandla futhi athuthukise isici samandla esistimu Yandisa impilo yesevisi. ama-capacitors.
Ama-capacitor wamandla ahambisanayo e-BSMJ asebenza kumasistimu kagesi we-AC anesilinganiso esilinganiselwe esingu-1000V nangaphansi ukuze kuthuthukiswe isici samandla nekhwalithi yamandla.
