Kodi Ntchito ya Woteteza Wosauka ndi Chiyani?

Ndikukumbukirabe tsiku lomwe mphezi inagunda kasitomala wanga kamodzi kokha ndipo inamuwonongera ndalama zokwana theka la miliyoni la madola. Kamodzi kokha, ndipo chogwirira chake chonse cha PLC chinasanduka chitsulo chodula.

Choteteza mafunde chimachotsa kapena kuyamwa ma voltage spikes oopsa asanafike pazida zodziwikiratu, kuti makina anu, deta, ndi phindu lanu zikhale zotetezeka. Ndaona chipangizo chosavuta ichi chikusunga mizere yonse yopangira ku China, Germany, ndi UK.

Ngati mugula zipangizo zoteteza dera Kuti mupeze zofunika pa moyo, mukudziwa kale kuti mtengo ndi wofunika. Pitirizani kuwerenga ndipo ndikukuwonetsani momwe mungachepetsere mtengo wonse wa umwini popanda kuchepetsa chitetezo.

Kumvetsetsa SChitetezo Cholimbikitsa m'mafakitale ndi m'mabizinesi?

Ndinayenda pa fakitale yopangira zida zamagalimoto ya maola 24 ku Wenzhou mwezi watha. Manejala anandiuza kuti ola lililonse logwiritsa ntchito nthawi yopuma limawononga 38,000 USD. Kuthamanga kamodzi kokha kungapangitse kuti nthawi yopumayo ichitike mumasekondi atatu ang'onoang'ono.

Chitetezo cha mafunde a mafakitale chimaletsa ma over-voltage osakhalitsa omwe amapangidwa ndi mphezi, kusinthana kwa gridi, ndi ma Variable Frequency Drives kuti asafikire ma PLC, ma seva, ndi maloboti. Ndimapangira makina awa a magalimoto aku Germany ndi malo osungira deta aku Britain sabata iliyonse.

Mungaganize kuti kukwera kwa madzi ndi kung'anima kwa moto. Zoona zake n'zoopsa kwambiri, komanso zotsika mtengo kuyimitsa kuposa kukonza.

Kumene kukwera kwa madzi kumachokera

Mphezi ndiye gwero lamphamvu kwambiri, koma si lofala kwambiri. Ndimayesa ma spikes ambiri kuchokera mkati kuposa kuchokera kumwamba. Kuzimitsa kwa mota ya 100 hp kumatha kubweza 1,800 V pa basi yomweyo yomwe imapatsa sensa yanu. Kuthamangaku kumatenga ma microsecond 50 okha, komabe ndi nthawi yayitali yokwanira kuboola gate oxide ya MOSFET. Ndawona izi mu fakitale yopangira ma CD yaku Vietnam. Tinawonjezera choteteza cha 40 kA Type 2 pa sub-panel, ndipo chiwopsezo cha kulephera chinatsika kuchoka pa matabwa atatu pamwezi kufika pa zero m'miyezi 14.

Kodi chiopsezocho ndi chachikulu bwanji?

Ndinapempha gulu langa kuti litenge deta kuchokera ku mafakitale 200 omwe timagwira ntchito. Tapeza kuti malo opanda chitetezo cha surge amawona kutsekedwa kosakonzekera ka 7.4 pachaka. Kutsekedwa kulikonse kumakhala maola 4.2. Ngati phindu lanu ndi 50 k USD patsiku, ndiye kuti ndi 1.5 miliyoni USD chaka chilichonse. Choteteza fakitale yonse chimawononga ndalama zosakwana 0.3% ya chiwerengerocho. Nthawi yobwezera ndi masiku 11, osati miyezi 11.

Miyezo yomwe muyenera kukwaniritsa

Ndimatumiza ku Europe, kotero chitetezo chilichonse chomwe ndimagulitsa chili ndi zilembo za CE ndi TÜV. Timayesa malinga ndi IEC 61643-11. Ngati mutumiza ku Germany, mufunikanso VDE 0675.
