Tionchar ualach dromchla na sreinge teasa

Níl roinnt custaiméirí soiléir faoi conas ualach dromchla na sreinge teasa . a thuiscint ach go gcinneann luach ualach dromchla na sreinge teasa méid na giniúna teasa den tsreang teasa, luas an ama teasa, agus saol na sreinge téimh .

Tagraíonn ualach dromchla na sreinge teasa don luach cumhachta a roinneann an sreang teasa in aghaidh an aonaid, marcáilte leis an tsiombail ω, agus is é an t -aonad w/cm 2.

Maidir leis an bhfoirnéis friotaíochta ardteochta, nuair a bhíonn an chumhacht mar an gcéanna, roghnaítear an t -ualach dromchla níos airde, rud a chiallaíonn gur féidir le méid na sreinge teasa roghnaithe a bheith níos lú agus gur féidir an t -ábhar a shábháil . Mar sin Is fachtóir tábhachtach é an rogha ceart ar ualach dromchla a úsáid in úsáid réasúnach na n -ábhar leictreamaigh .

The selection of surface load is related to the heating wire's material, specifications, structure, operating temperature, and heat dissipation conditions. It is also closely related to the atmosphere around the heating wire, the material of the supporting element, and the frequency of heating and cooling during use. The allowable surface load of the heating wire elements used in industrial resistance furnaces and civil electric heaters is very different due to different Úsáidí {. Dá bhrí sin, tá sé dodhéanta luach infheidhme go huilíoch a thabhairt .
