Isixazululo se-Voltage Case

I-VTIS ingakwazi ukuvikela ngokuphelele izinto ezibalulekile ezinciphisa ukuthembeka kokulawulwa kwamandla kwesibili kuma-breaker circuit, njengokuguquguquka kwamandla kagesi, ukuphazamiseka, ukugcwala kombani, ukulahleka kwamandla esikhashana, njll., okungabangela ukuthi uhlelo lokulawula luhluleke ukusebenza ngendlela evamile, ngaleyo ndlela kugwenywe ukuvala shaqa noma ukulimala ohlelweni oluyinhloko noma okokusebenza okubangelwa izizathu ezingenhla.

I-VTIS iqukethe imojula yokulawula i-oscillation ehambisanayo kanye nemojula yokucindezela kokuphazanyiswa kochungechunge. Imojula yokucindezela kokuphazanyiswa yochungechunge isebenza kumodi yesikhathi eside futhi ihlale igcina isimo sokusebenza esiqhubekayo. Lapho isilawuli sesibili sikagesi noma isiphazamiso sesifunda sesifunda singaphansi kweziphazamiso eziningi ezifana nokugcwala kombani, i-overvoltage engase ihlasele phansi, i-overvoltage yokusebenza, i-resonance overvoltage, i-voltage edlulayo, i-harmonic, ukuphazamiseka kwe-high-frequency, njll., ingacindezela ngempumelelo futhi ivikele ukusebenza okuthembekile nokuphephile kohlelo lwesibili.

I-VSAM ingavimbela ngokuphumelelayo othintana naye ukuthi angakhubeki ngenxa yokwehla kwamandla kagesi/ukucisha kukagesi okubangelwa ukuzamazama, ukugcina othintana naye ematasa ngesikhathi sokuzamazama, ukugwema ukukhubeka ngesikhathi sokuzamazama, nokuqinisekisa ukusebenza okuvamile nokuqhubekayo kwemishini.
I-VSAM inezintambo ezilula, ukufakwa kalula, ukusebenza okulula, ukunemba okuphezulu, kanye nohlu olubanzi lwesikhathi sokulwa nokuzamazama. Ingasetshenziselwa noma yiluphi uhlobo AC220V, AC380V contactor.

Isivikeli se-VSAM anti oscillation singaphinda siqedele ukutholwa nokusebenza kokulandela ngomkhondo okuhambisanayo kwe-voltage enkulu, sifinyelele imvamisa kanye nokukhiya isigaba se-voltage yama-mains, futhi singakwazi futhi ukubona inani elisheshayo le-voltage yamapayipi ngesikhathi sangempela, iqinisekise ukuthi ishintshela ekuphumeni kwe-inverter ye-VSAM ngaphakathi kwama-milliseconds lapho amandla amakhulu ehluleka, iqinisekisa ukuthintana futhi iphinde iqinisekise ukuthi imvamisa ayisebenzi. isiguquli kanye nesiqalisi esithambile.
I-VSAM isetshenziswa kakhulu emikhakheni efana ne-petroleum, amakhemikhali, i-metallurgical, izimayini, amandla, ukuvikelwa kwemvelo, izimboni zikamasipala, nezempi.

I-DCES iyithuluzi lokuvikela elisebenzayo elisebenza ngokuphepha likagesi eliklanyelwe iziguquli zefrikhwensi ye-voltage ephansi, okuhlanganisa ukusekela kokuphazamiseka kwe-voltage yesikhathi esifushane kanye nomthetho wokuncipha kwamandla kagesi. Ingakwazi ukubhekana nezinkinga ezifana nokushintshashintsha kwamandla kagesi kanye nokuphazamiseka kwesikhathi esifushane kagesi ngesikhathi sangempela.
I-DCES isebenzisa ama-supercapacitor ukugcina amandla, ikhipha amandla e-DC DC, futhi ixhuma kusiguquli semvamisa njengomthombo wamandla oyisipele. Ihlukaniswe ngokuphelele kusiguquli semvamisa ngesikhathi sokusebenza okuvamile. Uma inani eliguquguqukayo le-voltage yegridi yamandla lingafinyeleli inani elimisiwe, isistimu ayisebenzi futhi isesimweni sokulinda esishisayo; Lapho i-voltage iguquguquka ngaphakathi kwendawo yokuvikela, i-DCES iqala ukusebenza ukuze iqinisekise ukusebenza okujwayelekile kwesiguquli semvamisa; Lapho i-voltage yegridi yamandla ibuyiselwa, i-DCES iphuma ngokuzenzakalelayo kusimo sokusebenza futhi ishintshele esimweni sokulinda esishisayo, futhi isiguquli semvamisa sishintsha ngokuzenzakalelayo ukuze sinikwe amandla igridi yamandla; Uma isenzo sokufaka okuhlanganayo kwangaphandle noma isiguquli sefrikhwensi siyeka ukusebenza, idivayisi iyaphuma ngokuzenzakalelayo bese ishintshela esimweni sokulinda esishisayo.

I-VAAS iyisisetshenziswa sokuvikela esisebenzayo esisebenza ngokuphepha kagesi esisebenza ngezindlela eziningi esihlanganisa ukwesekwa kokuphazamiseka kwe-voltage yesikhathi esifushane, ukulawulwa kokwehla kwe-voltage okwesikhashana, ukulawulwa kokukhuphuka kwesikhashana kwamandla kagesi, ukucindezelwa kokuphazanyiswa komthwalo, ukucindezelwa kokungalingani kwezigaba ezintathu, njll. Ingakwazi ukulawula ngaphandle komthungo izinkinga ezifana nokuzamazama kwamandla kanye nokuphazamiseka kwesikhathi esifushane kagesi ngesikhathi sangempela.

I-VAAS inganqamula umthombo wamandla we-voltage sag isikhathi esifushane, ngokuvamile okungu-1~3s, futhi inikeze amandla okulayisha phakathi nomzuzu wokuncibilika kwe-voltage. Ingakwazi ukusekela ukunikezwa kwamandla, ilungise i-voltage sag, ilungise futhi inyuse i-voltage, isuse ireferensi yomthwalo futhi inikeze ukuqapha kwesikhathi sangempela se-fault arc.

I-VAAS iqukethe isigaba se-thyristor bypass, isigaba sokuguqula, nesigaba sokugcina amandla e-supercapacitor. Isigaba se-thyristor bypass sisetshenziselwa ukuvala ngokushesha i-thyristor uma kwenzeka i-voltage yesistimu engavamile. Ingxenye ye-inverter isetshenziselwa ukugcina amandla kumadivayisi okugcina amandla kanye ne-voltage yesinxephezelo esiphumayo. Ingxenye yokuhlunga iqinisekisa ukuthi i-voltage eseceleni yomthwalo okhiqiziwe ihlangabezana nezidingo.
