Pakadali pano, zida zogawa magetsi ndi makina opangira magetsi komanso kugawa m'makampani a petrochemical nthawi zambiri amagwiritsa ntchito mphamvu ya AC yamagetsi a UPS.Nthambi zambiri zitatha kuyendetsedwa ndi kukonzedwa ndi otsika ma voltages otsika, amatulutsa 24V DC ndi 110V AC kudzera pa otembenuza a AC/DC kapena otembenuza ndi zida zina kuti apereke katundu wamagetsi pamapanelo ofanana.
Bokosi losinthira (bokosi) lomwe limayikidwa m'makampani a petrochemical liyenera kuyikidwa m'nyumba ndi malo abwino okhala.Ngati kuyika panja kuli kofunika, madera omwe ali ndi malo ovuta ayenera kupewedwa, ndipo mabokosi ogawa (mabokosi) oyenerana ndi chikhalidwe cha chilengedwe cha malo oyikapo ayenera kusankhidwa.
Chifukwa cha zofunikira zopanga, pali zonyamula zambiri zamapampu mumakampani a petrochemical, ndipo zonyamula zambiri zamapampu zimakhala ndi zoyambira zofewa.Kugwiritsa ntchito zoyambira zofewa kumawonjezeranso zomwe zikuchitika pamakina ogawa zida zamagetsi mumakampani a petrochemical.Pakalipano, oyambitsa zofewa ambiri amagwiritsa ntchito 6 single-pulse rectifiers kuti asinthe AC panopa kukhala DC, ndipo zotsatira zake zimakhala makamaka 5th, 7th ndi 11th harmonics.Kuwonongeka kwa ma harmonics mu pulogalamu ya petrochemical system kumawonekera makamaka pakuwonongeka kwa uinjiniya wamagetsi komanso kulakwitsa kwa kuyeza kolondola.Kafukufuku wasayansi akuwonetsa kuti mafunde a ma harmonic angapangitse kuwonongeka kwina kwa ma transfoma, omwe angayambitse kutenthedwa, kufulumizitsa ukalamba wa zipangizo zotetezera ndi kuwononga kuwonongeka.Kukhalapo kwa pulse pakali pano kudzawonjezera mphamvu yowoneka bwino komanso kukhala ndi vuto lalikulu pakuchita bwino kwa thiransifoma.Nthawi yomweyo, ma harmonics amakhudza mwachindunji ma capacitor, ophwanya ma circuit, ndi zida zotetezera relay mumagetsi.Pazida zambiri zoyesera, muzu weniweniwo umatanthauza masikweya amtengo wapatali sungathe kuyeza, koma mtengo wapakati ukhoza kuyeza, ndiyeno mawonekedwe ongoyerekeza amachulukitsidwa ndi index yabwino kuti apeze mtengo wowerengera.Pamene ma harmonics ali aakulu, kuwerengera koteroko kumakhala ndi zosiyana zazikulu, zomwe zimapangitsa kuti miyeso ikhale yosiyana.
Mavuto omwe mungakumane nawo?
1. Kuyambitsa mavuto a blowers osiyanasiyana ndi mapampu
2. Kusintha kwafupipafupi kumapanga ma harmonics ambiri, omwe amakhudza ntchito yotetezeka ya zida zamagetsi mu dongosolo.
3. Chindapusa chosavomerezeka chifukwa cha mphamvu yocheperako (malinga ndi "Power Factor Adjustment Electricity Fee Measures" yopangidwa ndi Unduna wa Zamadzi ndi Mphamvu Zamagetsi akampani yathu komanso Bungwe la Price Bureau la kampani yathu).
4. Makampani a petrochemical ndi kampani yogwiritsa ntchito mphamvu zambiri.Chifukwa cha kusintha kwa ndondomeko ndi malamulo a kampani yathu yogwiritsira ntchito magetsi, zikhoza kukhudzidwa ndi kusiyana kwa ndalama za magetsi.
Yankho lathu:
1. Ikani zida zolipirira za hy-type high-voltage reactivity power automatic pa 6kV, 10kV kapena 35kV mbali ya dongosolo kuti mulipire mphamvu yochitapo kanthu, kuwongolera mphamvu yamagetsi, kupanga mphamvu ya reactance, ndikuwongolera pang'ono kugunda kwamagetsi;
2. Mbali yamagetsi yamagetsi yamagetsi imagwiritsa ntchito mphamvu yowonongeka yowonongeka kuti iwononge katundu wokhazikika mu nthawi yeniyeni ndikusunga kudalirika kwa mphamvu yamagetsi;
3. The yogwira fyuluta Hongyan APF waikidwa pa otsika-voteji 0.4kV mbali kusamalira harmonics dongosolo, ndi malo amodzi chitetezo chipukuta misozi chipangizo ntchito kubwezera zotakataka mphamvu ya dongosolo kusintha mphamvu chinthu.
