Existuje mnoho norem pro hodnocen\u00ed kvality topn\u00fdch t\u011bles. Jak m\u016f\u017eeme jednodu\u0161e otestovat kvalitu topn\u00e9ho prvku v na\u0161\u00ed ka\u017edodenn\u00ed pr\u00e1ci a \u017eivot\u011b? Dnes se s v\u00e1mi pod\u011bl\u00edm o to, jak pomoc\u00ed multimetru otestovat kvalitu topn\u00e9ho \u010dl\u00e1nku.<\/p>\n\n\n\n
Nastavte multimetr na rozsah 1 K ohm a p\u0159ilo\u017ete ob\u011b sondy na oba konce topn\u00e9ho dr\u00e1tu.<\/p>\n\n\n\n
Pokud multimetr zobraz\u00ed ur\u010ditou hodnotu, znamen\u00e1 to, \u017ee topn\u00fd vodi\u010d funguje norm\u00e1ln\u011b. Zapi\u0161te si hodnotu odporu. Pokud se nezobraz\u00ed \u017e\u00e1dn\u00e1 hodnota, znamen\u00e1 to, \u017ee topn\u00fd dr\u00e1t je p\u0159eru\u0161en\u00fd a topn\u00e9 t\u011bleso nelze pou\u017e\u00edt.<\/p>\n\n\n\n
Pomoc\u00ed vzorc\u016f 220250\/hodnota odporu nebo 380<\/em>380\/hodnota odporu, m\u016f\u017eete vypo\u010d\u00edtat v\u00fdkon. Pokud se vypo\u010dten\u00fd v\u00fdkon odchyluje od jmenovit\u00e9ho v\u00fdkonu o m\u00e9n\u011b ne\u017e 5%, je topn\u00e9 t\u011bleso v po\u0159\u00e1dku.<\/p>\n\n\n\n Pokud je odchylka v\u00fdkonu velk\u00e1, znamen\u00e1 to, \u017ee v\u00fdrobn\u00ed proces je nestandardn\u00ed. Pokud je hodnota v\u00fdkonu nadm\u011brn\u011b vysok\u00e1, nap\u0159\u00edklad nad 10 000, znamen\u00e1 to, \u017ee v topn\u00e9m vodi\u010di do\u0161lo ke zkratu, kter\u00fd by mohl v\u00e9st k po\u017e\u00e1ru nebo jin\u00fdm elektrick\u00fdm poruch\u00e1m. V takov\u00e9m p\u0159\u00edpad\u011b by se topn\u00e9 t\u011bleso nem\u011blo pou\u017e\u00edvat.<\/p>\n\n\n\n GlobalQT se specializuje na v\u00fdrobu vysoce kvalitn\u00edch k\u0159emenn\u00e9 topn\u00e9 \u010dl\u00e1nky<\/a>.
