Imvelaphi yeProjekthi
ILiunan Second Expressway ikwabizwa ngokuba yiLiuzhou Jingheshan ukuya kwiNanning Expressway.Umgca ophambili wale projekthi uqala kwindawo ekufutshane neDolophu yaseLuoman, kwisiXeko saseLiuzhou, uqhagamshela iLiuzhou Expressway ngeSanjiang, kwaye ekugqibeleni ufika kwidolophu yaseWutang, kwisiXeko saseNanning, naseLiuzhou South Expressway.Uhola wendlela ngomnye weendlela ezinomthamo omkhulu wezithuthi eGuangxi kwiminyaka yakutshanje.Umzila wesibini ohamba ngokukhawuleza kwisiXeko saseLiunan unobude obuziikhilomitha ezimalunga ne-199 kunye nesantya soyilo seekhilomitha ezili-120 ngeyure.Yamkela umgangatho weendlela ezimbini zeendlela ezine kwaye yakha imigca ye-8 yokudibanisa ngexesha elinye.Utyalo-mali lulonke luqikelelwa kwi-20.749 yeebhiliyoni zeeyuan.Kukho iibhulorho ze-13, iindawo zenkonzo ze-4, i-3 Emva kokuba iprojekthi ivula i-traffic, ixesha lokuqhuba ukusuka e-Shanglin ukuya e-Nanning liya kufinyezwa kwi-1 iyure, ngokufanelekileyo ukukhulula uxinzelelo lwezithuthi kwi-original Liunan Expressway, ngakumbi ukusuka e-Liujing ukuya e-San'an.
Usetyenziso
Le projekthi isebenzisa iimveliso zembuyekezo yembuyekezo yamandla enkampani yethu, kubandakanywa iijenereyitha ze-static var, izixhobo zembuyekezo ezikrelekrele ezidibeneyo ezichasene ne-harmonic, njl.Ukuphucula ngokufanelekileyo into yamandla, ukunciphisa ilahleko, kunye nokuqinisekisa ukusebenza okuzinzileyo nokuthembekileyo kwezixhobo zamandla.
Izinto ezilungileyo zeemveliso ze-static var generator
1. Umthwalo we-capacitive inductive -1 ~ 1 imbuyekezo.
2. Imbuyekezo yokungalingani kwezigaba ezithathu.
3. I-frequency switching frequency yi-10K, kwaye imbuyekezo eguquguqukayo yimpendulo ekhawulezayo kakhulu.
I-HYSVG static var generator ibona umthwalo wangoku ngexesha langempela ngokusebenzisa i-transformer yangoku yangaphandle (CT), ihlalutya umxholo wamandla osebenzayo womthwalo wangoku ngokubala kwe-DSP yangaphakathi, kwaye emva koko ilawula i-PWM yesiginali ye-generator ukuthumela umqondiso wokulawula IGBT yangaphakathi ngokwexabiso elimiselweyo.Yenza i-inverter ivelise imbuyekezo yamandla asebenzayo ahlangabezana neemfuno, kwaye ekugqibeleni uqonde injongo yembuyekezo yamandla asebenzayo.
HY series ezikrelekrele ezidityanisiweyo anti-harmonic low-voltage amandla capacitor isixhobo imbuyekezo sisizukulwana esitsha izixhobo imbuyekezo amandla reactive ezisetyenziswa 0.4KV low-voltage womnatha wokuhambisa ukusebenza kakuhle, ukonga amandla, ukucinezelwa harmonic kunye nokuphuculwa factor factor.Ithatha indawo yolawulo lwemveli ngembuyekezo yamandla asebenzayo akrelekrele.Sisixhobo sembuyekezo samandla esisebenzayo esenziwe ngamalungu anjengamaqhekeza, iifuse, iiswitshi zokutshintsha, izihluzi zokucoca kunye neecapacitors zamandla.
I-Anti-harmonic i-smart power capacitors yenzelwe imeko yokuba umxholo we-harmonic womnatha wamandla uphezulu kwaye i-smart capacitors eqhelekileyo ayikwazi ukusebenza ngokuqhelekileyo.ifuthe kunye nokuphucula umgangatho wokusetyenziswa kombane.
