Mitengo yemagetsi iri kukwira, uye varidzi vemafekitari vakawanda vari kutarisa pamatenga edzimba dzavo dzisingashandiswi senzvimbo dzinogona kuita solar PV.
Chii chinofanira kutanga kuuya? Vazhinji varidzi vanotanga nekubvunza makambani ezuva nemitengo yemodule. Icho chinongova hafu yemufananidzo. Nokuda kwechivako chefekitari chiripo chakagadzirwa nesimbi, danho rokutanga nderokuongorora kwemaitiro. Kana denga risingakwanisi kutsigira zvakachengeteka sisitimu, iyo purojekiti yehupfumi haiwedzere.
Imwe fungidziro yeindasitiri inoisa mwero wekupasa kwePV mutoro-macheki pamatenga esimbi aripo pasi pe50%. Inoda kusvika hafu yezvivako zvekare zvefekitari zvingada kusimbiswa zuva risati raiswa. Kusvetuka ongororo uye kuenda zvakananga kumisikidzwa kunogona kutungamira kune purlin deformation, kudonha kwedenga, kana kunyangwe zviitiko zvekuchengetedza.
Iri gwaro rinotsanangura macheki matatu, maitiro avo ekupasa / kutadza, uye mutengo wekuratidza kana denga rikasapfuura ongororo.
Tarisa 1: Kutakura-Kutakura Kugona
Chekutarisa
Tarisa uone kana dhizaini yepakutanga iine huwandu hwekutakura hwakakwana munzvimbo yakachengetedzwa. A padenga PV sisitimu (modules, anokwirisa dhizaini uye tambo), akaiswa anoenderana nedenga remutsetse, anowedzera anenge. 15–26 kg/m² (0.15–0.26 kN/m²).
Izvozvo zvingasanzwika sezvizhinji, asi ndeye zvachose yakafa mutoro. Iyo yekutanga dhizaini inowanzo tora mhenyu ye 0.5 kN/m² chete padenga risina kuitirwa kuwanikwa nguva dzose. Kamwe iyo PV yakafa mutoro inosanganiswa nemhepo uye chando mitoro, inogona kushandisa nyore kumusoro yakasara.
Pass/Fail Criteria
| Inspection chinhu | Pass | Fail |
| Stress ratio pasi peakasanganiswa akafa, mhenyu, mhepo uye sinou mutoro makesi | Mukati memuganhu unobvumirwa | Inodarika muganhu |
| Main-frame deflection | ≤ L/250 (yakajairika indasitiri tsika) | Inodarika muganhu |
| Column-top displacement | Mukati mekodhi inogumira | Inodarika muganhu |
Kana denga rikakundikana: Simbisa iyo huru furemu, semuenzaniso nekuwedzera saizi yenhengo kana kuwedzera bracing. Ichi chiyero chinodhura chekusimbisa uye chinoda dhizaini-yakananga engineering dhizaini.
Tarisa 2: Purlin Span uye Chikamu Saizi
Chekutarisa
PV mounting clamps inogadziriswa kune purlins. Nekuda kwekuti mapurlins aive akakurisa mitoro yaivepo, imwezve 15-26 kg/m² inogona kuasundidzira kupfuura yaanobvumidzwa. Kune portal-frame fekitori zvivakwa zvine C- kana Z-chikamu purlins, iyi mitemo miviri yechigunwe inogona kushandiswa kutanga kuongorora:
- Purlin span inosvika 6 m ine chikamu chezita pazasi 180 → inogona kudarika miganhu inotenderwa
- Purlin span inosvika 8 m ine chikamu chezita pazasi 220 → inogona kudarika miganhu inotenderwa
Pass/Fail Criteria
| Inspection chinhu | Pass | Fail |
| Purlin stress ratio | Mukati memuganhu unobvumirwa | Inodarika muganhu |
| Purlin kutsauka | ≤ L/150 | Inodarika muganhu |
| Kurongeka/kusunga (kana uchirebesa> 6 m) | Kanenge mitsara miviri | Mutsara mumwe chete; njodzi yekusagadzikana kwe lateral |
Kana mapurlins asina kukwana asi furemu huru iine huwandu hwakakwana, kusimbisa kana kutsiva chete purlins isarudzo inodzoreka uye kazhinji inodhura zvishoma pamatanho matatu ekusimbisa.
Tarisa 3: Corrosion Condition
Chekutarisa
Ongorora chivharo chekudzivirira uye kurasikirwa kunoenderana nekuora kwepamuchinjikwa-sectional nzvimbo. Nyatsocherechedza nzvimbo dzinoungana guruva kana mvura, nzvimbo dzinogara dzichinyorova nekuwomeswa, dzinobatanidza nenzvimbo dzakavanzwa, uye mipendero yemavhuriro edenga.
Method: Chekutanga ongorora iyo yekupfeka kuti haina kukanganisa. Panzvimbo dzakakuvadzwa, shandisa ultrasonic ukobvu geji kana macalipers kuyera iwo chaiwo ukobvu hwezvinhu uye woenzanisa neiyo yekutanga chikamu chiyero.
Pass/Fail Criteria
| Inspection chinhu | Pass | Fail |
| Kuvhara kwekudzivirira | Yakakwana kana kugadziriswa | Yakapararira coating kukundikana |
| Muchinjikwa-chikamu kurasikirwa nekuda kwekuora | ≤ 5% | > 5% |
| Kubatanidza (welds / mabhaudhi) | Hapana kusununguka kana kutsemuka | Lose fasteners kana kuputika welds |
Kana kurasikirwa kwepamuchinjikwa nekuda kwekuora kunopfuura 5%, shandisa kuchengetedzwa kwekuora uye simbisa chikamu chakakanganisika usati waongorora zvakare simba redenga rePV mitoro. Nyaya dzekubatanidza dzinotora pekutanga pane zvimwe zvese: gadzirisa zvinongedzo usati wafunga kuisa solar.
Kana Denga Rakakundikana: Kunoenda Mari
Zvinoratidza indasitiri yemitengo:
| Basa rekugadzirisa | Indicative cost | Notes |
| Structural verification calculations | US$1,400–4,200 | Zvinodiwa; shandisa inyanzvi yekugadzira engineering femu kana simbi-yechimiro kambani yekumisikidza modhi uye yekuongorora. |
| Purlin kusimbisa / kutsiva | US$2,800–7,000 | Iyo yakajairika yekusimbisa chikamu |
| Main-frame kusimbisa | US$11,000–21,000 | Wedzera saizi yenhengo / wedzera bracing; dhizaini-chaiyo dhizaini inodiwa |
| Kusimbisa nheyo | US$14,000–28,000 | Sarudzo yakanyanyisa; tanga wasimbisa kana zvichidikanwa |
Chenjedzo: Imwe fekitori yakaisa PV isina kuita masvomhu ekutanga. Kwapera gore, purlins dzayo dzakadzikira ne5 cm. Kugadzirisa uye kusimbisa mari inoita US$25,000, uye kugadzira kwakamiswa kwemwedzi.
Kuongorora padenga kunongoita zviuru zvishoma zvemadhora. Kurisvetuka kunoreva kuisa denga rinokosha mazana ezviuru zvemadhora—uye mutsara wose wokugadzira—panjodzi.
Mushure meKuongorora: Iyo Nyaya Yekubatanidza Dhizaini
Kana denga rapfuura ongororo, funga kubatanidza PV mudhizaini yedhizaini pane kushandisa yakajairwa chivakwa-yakaiswa PV (BAPV) retrofit.
- PV modules inogona kutsiva chikamu chedenga rakavharika mune chivakwa-yakabatanidzwa PV (BIPV) dhizaini, inogona kuderedza pane kuwedzera mutoro usingaperi.
- Ronga iyo yekumisikidza uye yekubatanidza ruzivo mumadhirowa kubva pakutanga kudzivirira pane-saiti kugadzirisa.
- Kune matenga akareba-akareba ane mashoma emutoro simba, BIPV inogona kubvisa kana kuderedza zvakanyanya mari yekusimbisa.
Nokuda kwechivako chefekitari chitsva, izvi zvinoreva “dhizaini imwe chete, chikamu chimwe chokuvaka, uye kugadzirwa kwemagetsi kunovakwa. Kune fekitori iripo iyo inopfuura ongororo, yakajairwa retrofit inoramba iri sarudzo inoshanda-asi ruzivo rwekubatanidza uye kugovera mutoro kunofanirwa kubatwa neboka rekugadzira rine hunyanzvi hwekugadzira simbi.
Mibvunzo Inowanzo bvunzwa
Q1: Kuongororwa kwechimiro kunodiwa here usati waisa solar padenga remba?
Hongu. Kufungidzira kweindasitiri kunoisa mwero wekupasa kwePV load cheki pamatenga esimbi aripo pasi pe50%. Masvomhu ekuverenga anobatsira kubata njodzi iyi; paUS$1,400–4,200, ndeimwe yedziviriro isingadhure muchirongwa ichi.
Q2: Chivakwa chefekitori chine makore makumi maviri chichiri kutsigira solar?
Zera rega harisi sarudzo. Chivako chekare chinogona kupfuura kana ngura ikadzorwa uye dhizaini yepakutanga iine huwandu hwakakwana mukuchengetedza. Kana kurasikirwa kwechikamu chine chekuita nekuora kwakapfuura muganhu unobvumirwa, shandisa kudzivirira kwegora uye simbisa kutanga.
Q3: Ndiani anofanira kugadzirira gwaro rekuongorora?
Kambani yekugadzira mainjiniya kana simbi-yakaumbwa kambani inofanirwa kuburitsa iyo report. Inofanirwa kunyora misanganiswa yemutoro, kushushikana kweretiyo, kutsauka zvakawanikwa, uye chero kurudziro yekusimbisa.
Q4: Ndeipi purlin span uye saizi yechikamu inowanzokodzera padenga rezuva?
Semutemo wekutanga wezvigunwe, C- kana Z-chikamu purlins ine chikamu chinodudzwa chinosvika zana nemakumi masere pakureba inosvika 6 m, kana 220 kutenderera 8 m, inogona kupfuura pasi pePV mitoro. Kukodzera kwekupedzisira kunofanirwa kusimbiswa nekuverenga kwemaitiro.
Hauna chokwadi chekuti denga rako rinogona kutsigira solar? Tumira span, saizi yepurlin, gore rekuvaka, uye mafoto epadenga kuti uwane yemahara yekutanga ongororo. Email: info@xzbesta.com
