Welded mesh factory kesi

Ruzivo rwekutanga rwevashandisi
Fekitari yakashongedzerwa mesh inonyanya kugadzira akasiyana-siyana akaiswa mesh machira, mambure efence, mambure euswa, gabion net, hook net, barbecue net, tsuro matanga, etc. 1000 kVA uye 1630 kVA transformers.Iyo dhizaini yemagetsi system dhizaini ndeiyi inotevera:

Data chaiyo yekushandisa
Simba rese remuchina wewelding une 1000KVA transformer i1860KVA, avhareji simba chinhu PF=0.7, uye kushanda kushanduka ikozvino 1050-2700A.Simba rose remuchina welding ine 630KVA transformer i930KVA, avhareji simba chinhu PF=0.7, uye kushanda kushanduka ikozvino Ikozvino i570-1420A.

Simba System Situation Analysis
Welding muchina simba rekupa rinonyanya kushandiswa kudzika pasi hombe yazvino mutoro, iri nonlinear mutoro.Iyo midziyo inogadzira nhamba yakakura yeharmonics panguva yekushanda.Iyo harmonic yazvino yeyakajairika harmonic sosi inopinzwa mugedhi remagetsi, uye iyo grid impedance inogadzira harmonic voltage, zvichikonzera iyo grid voltage uye yazvino Distortion inokanganisa kunaka kwemagetsi uye kuchengetedza kwekushanda, inowedzera kurasikirwa kwemutsara uye voltage offset, uye inowedzera simba.Naizvozvo, zvinodikanwa kuti usarudze system software ine harmonic kudzvanya kudzvanya harmonics, kutsiva reactive mitoro, uye kunatsiridza simba chinhu.

Sefa reactive simba muripo wekurapa chirongwa
Zvinangwa zveutongi
Dhizaini yemafirita muripo wemidziyo inosangana nezvinodiwa zveharmonic kudzvinyirira uye reactive simba kudzvinyirira manejimendi.
Pasi peiyo 0.4KV sisitimu yekushandisa modhi, mushure meiyo sefa yekubhadhara midziyo yaiswa mukushanda, iyo pulse ikozvino inodzvinyirirwa, uye mwedzi wepakati simba chinhu chiri kutenderera 0.92.
High-order harmonic resonance, resonance overvoltage, uye overcurrent inokonzerwa nekubatanidza kune sefa muripo webazi redunhu hazvizoitiki.

Mazano ekugadzira
Zvichienderana nemamiriro ezvinhu chaiwo ebhizinesi, kambani inonyatso tarisa simba remutoro uye kudzvanywa kweharmonic kwesefa reactive simba muripo wemuchina wewelding, uye inoisa sefa reactive simba rekubhadhara mudziyo pane 0.4KV yakaderera-voltage parutivi rwebhizinesi. transformer kudzvinyirira harmonics uye kubhadhara reactive simba kuvandudza simba chinhu.
Munguva yekushanda kwemuchina we welding, 3 nguva dze150HZ, 5 nguva dze250HZ uye pamusoro peharmonics dzinogadzirwa.Naizvozvo, mukugadzirwa kweiyo reactive simba muripo weyechipiri welding muchina sefa, iyo frequency ye150HZ, 250HZ uye yakatenderedza inofanirwa kugadzirwa kuti ive nechokwadi chekuti sefa yekubhadhara loop inogona kudzvanya zvinonzwisisika pulse ikozvino uku uchibhadhara reactive mutoro uye kuvandudza simba. factor.

Effect analysis mushure mekuiswa kwefirita muripo
Muna Kubvumbi 2010, iyo sefa reactive simba rekubhadhara mudziyo wemuchina wewelding wakatumirwa kunze kwefekitori.Chishandiso ichi chinoteedzera otomatiki shanduko yemuchina wekushongedza, inodzvanya iyo harmonic muripo rekuita simba munguva chaiyo, uye inovandudza simba chinhu.mashoko sezvinotevera:

Mushure mesefa yemuripo mudziyo waiswa mukushandiswa, simba rekuchinja curve rinenge 0.97 (chikamu chakasimudzwa chingangoita 0.8 kana mudziyo wemuripo wesefa wabviswa)

Rodha kushanda
Iko kushandiswa kweiyo 1000KVA transformer inodonha kubva ku1250A kusvika ku1060A, chiyero chekudzikisa che15%, uye kushanda ikozvino kwe630KVA transformer inodonha kubva ku770A kusvika ku620A, kuderedzwa kwe19%.Mushure mekubhadhara, kukosha kwekuderedza kurasikirwa kwesimba ndeyeWT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24×{(0.85×2000)/2000}2×0.4≈16 (kw h) Muchidimbu, Pd ndiko kurasikirwa-pfupi-kurasikirwa kweshanduko, iyo 24KW, uye kuchengetedzwa kwegore negore kwemari yemagetsi ndeye 16 * 20 * 30 * 10 * 0.7 = 67,000 yuan (zvichienderana nekushanda maawa makumi maviri a zuva, mazuva makumi matatu pamwedzi, mwedzi gumi pagore, 0,7 yuan pakWh).

simba factor situation
Iyo yakazara simba chinhu chebhizinesi chakawedzera kubva 0.8 kusvika 0.95 mumwedzi wazvino, uye mwedzi wega wega simba chinhu chicharamba chiri pa 0.96-0.98 mune ramangwana, uye bhonasi yepamwedzi ichava 3000-5000 yuan.

mukupedzisa
Iyo sefa reactive simba rekubhadhara mudziyo wemagetsi welding muchina inokwanisa kudzvanya maharmonics uye kudzoreredza reactive simba, kugadzirisa dambudziko reiyo reactive magetsi faindi mumabhizinesi, kuwedzera simba rekubuda kwevashanduri, kuderedza kunoshanda kurasikirwa kwekuwedzera, kuwedzera kugadzirwa, uye kuunza yakakosha hupfumi. mabhenefiti kumabhizinesi.Dzokera pamari isingasviki gore.Naizvozvo, iyo reactive simba rekubhadhara mudziyo unogadzirwa nekambani unogutsikana kwazvo, uye uchakwezva vatengi vazhinji mune ramangwana.
