4, Mounting Isimo
1) Izinga lokushisa lomoya elizungezile
1) Uma kucatshangelwa izinga lokushisa elingaphezu kwe-ambient ukusheshisa ukuguga kwezingxenye zepulasitiki, umkhawulo ongaphezulu awukho ngaphezu kuka +40 ℃.
Uma kucatshangelwa ukuthi izinga lokushisa le-ambient eliphansi ngokwedlulele
ishintsha ukulingana kwelungu lesakhiwo, umkhawulo ophansi ngokuvamile awukho ngaphansi kuka -5℃.
Uma ucabangela impilo yesevisi ye-breaker circuit, inani elijwayelekile lamahora angu-24 alikho ngaphezu kuka-+35 ℃.

Qaphela:

① Isimo sokusebenza senani eliphansi lomkhawulo ngu--10℃ noma -25℃.Umsebenzisi udinga ukumemezela enkampanini lapho e-oda.
②Isimo sokusebenza senani eliphezulu lomkhawulo elingaphezu kuka-+40℃ noma inani eliphansi lomkhawulo elingaphansi kuka -25℃, umsebenzisi udinga ukuxoxisana nenkampani.
2) Indawo yokufaka
Ukuphakama akudluli ku-2000m;
Izidingo zesekethe yokuvikela;
Iphuzu lokufaka libala isifunda esifushane samanje i-Ik ayikho ngaphezu kwe-3000A;
I-circuit breaker izofakwa ngokuhambisana nezidingo zokusetshenziswa kwencwadi, ukuthambekela okuqondile kwe-breaker circuit akufanele kudlule i-5 °, Ukudlidliza kwemvelo akukho ngaphezu kwe-5g.
3) Izimo zasemkhathini
Umswakama ohlobene nomkhathi aweqi ku-50% ekushiseni komoya endaweni +40 ° C. Ungaba nomswakama ophakeme ohlobene emazingeni okushisa aphansi.Isilinganiso sanyanga zonke somswakama ophezulu oyisihlobo senyanga emanzi kakhulu singama-90%, kanti izinga lokushisa elincane elivamile lenyanga ngu +25 ° C futhi kucatshangelwa ukuminyana ebusweni bomkhiqizo ngenxa yokushintsha kwezinga lokushisa.
4) Izinga lokungcola
Izinga lokungcola likuleveli 3.
5) Isigaba sokufakwa
Isekhethi yokuvikela i-circuit breaker ifakwe esigabeni III.
I-6) Isigaba sesiphambano socingo silungiselelwe ngokusho kwesilinganiso esiphezulu sokushisa esivamile se-Ith se-breaker circuit.
