Exist\u0103 multe standarde pentru evaluarea calit\u0103\u021bii elementelor de \u00eenc\u0103lzire. Cum putem testa pur \u0219i simplu calitatea unui element de \u00eenc\u0103lzire \u00een munca \u0219i via\u021ba noastr\u0103 de zi cu zi? Ast\u0103zi, voi \u00eemp\u0103rt\u0103\u0219i cu dvs. cum s\u0103 utiliza\u021bi un multimetru pentru a testa calitatea unui element de \u00eenc\u0103lzire.<\/p>\n\n\n\n
Seta\u021bi multimetrul pe domeniul 1K ohm \u0219i plasa\u021bi cele dou\u0103 sonde la ambele capete ale firului de \u00eenc\u0103lzire.<\/p>\n\n\n\n
Dac\u0103 multimetrul afi\u0219eaz\u0103 o anumit\u0103 valoare, \u00eenseamn\u0103 c\u0103 firul de \u00eenc\u0103lzire func\u021bioneaz\u0103 normal. Lua\u021bi not\u0103 de valoarea rezisten\u021bei. Dac\u0103 nu este afi\u0219at\u0103 nicio valoare, aceasta indic\u0103 faptul c\u0103 firul de \u00eenc\u0103lzire are o ruptur\u0103, iar elementul de \u00eenc\u0103lzire nu poate fi utilizat.<\/p>\n\n\n\n
Prin utilizarea formulelor 220250\/valoarea rezisten\u021bei sau 380<\/em>380\/valoarea rezisten\u021bei, pute\u021bi calcula puterea. Dac\u0103 puterea calculat\u0103 se abate cu mai pu\u021bin de 5% de la puterea nominal\u0103, elementul de \u00eenc\u0103lzire este bun.<\/p>\n\n\n\n Dac\u0103 abaterea de putere este mare, aceasta indic\u0103 faptul c\u0103 procesul de fabrica\u021bie este inferior standardelor. Dac\u0103 valoarea puterii este excesiv de mare, cum ar fi peste 10.000, \u00eenseamn\u0103 c\u0103 exist\u0103 un scurtcircuit \u00een firul de \u00eenc\u0103lzire, ceea ce ar putea duce la un incendiu sau la alte defec\u021biuni electrice. \u00cen acest caz, elementul de \u00eenc\u0103lzire nu trebuie utilizat.<\/p>\n\n\n\n GlobalQT este specializat\u0103 \u00een fabricarea de elemente de \u00eenc\u0103lzire din cuar\u021b<\/a>.
