V na\u0161om regi\u00f3ne (\u010desk\u00e9 a slovensk\u00e9 normy) sa stret\u00e1vame najm\u00e4 s dvoma prvkami: uzem\u0148ovac\u00edm kol\u00edkom v z\u00e1suvke a kovov\u00fdm kontaktom (z\u00e1suvky) na z\u00e1str\u010dke.<\/p>\n\n\n\n
Ochrann\u00fd vodi\u010d (uzemnenie)<\/p>\n\n\n\n
Tento prvok sl\u00fa\u017ei ako uzemnenie. Zatia\u013e \u010do dva hlavn\u00e9 kol\u00edky z\u00e1str\u010dky ved\u00fa pr\u00fad, aby zariadenie fungovalo, kovov\u00fd kontakt z\u00e1rove\u0148 funguje ako poistka.<\/p>\n\n\n\n
Ako to funguje: Ak sa v zariaden\u00ed vyskytne porucha (napr. v pr\u00e1\u010dke alebo \u017eehli\u010dke) a pr\u00fad dosiahne kovov\u00fd kryt, tento kontakt odvedie nebezpe\u010dn\u00e9 nap\u00e4tie do zeme.<\/p>\n\n\n\n
Ochrana zdravia: T\u00fdm sa zabr\u00e1ni \u00farazu elektrick\u00fdm pr\u00fadom pri dotyku zariadenia. Namiesto toho okam\u017eite zareaguje isti\u010d alebo pr\u00fadov\u00fd chr\u00e1ni\u010d (RCD) a vypne nap\u00e1janie.<\/p>\n\n\n\n
Rozdiely medzi typmi z\u00e1str\u010diek
Mo\u017eno ste si v\u0161imli, \u017ee z\u00e1str\u010dky nie s\u00fa v\u0161etky rovnak\u00e9:<\/p>\n\n\n\n
Okr\u00fahle z\u00e1str\u010dky s otvorom (typ E\/F \u2013 \u201eUni-Schuko\u201c): Tieto maj\u00fa otvor pre uzem\u0148ovac\u00ed kol\u00edk a kovov\u00e9 p\u00e1siky po stran\u00e1ch. S\u00fa ur\u010den\u00e9 pre zariadenia s kovov\u00fdm krytom, ktor\u00e9 je potrebn\u00e9 uzemni\u0165 (chladni\u010dky, po\u010d\u00edta\u010de, pr\u00e1\u010dky). Ploch\u00e9 z\u00e1str\u010dky (typ C): Tieto nemaj\u00fa \u010fal\u0161\u00ed kovov\u00fd kontakt. Pou\u017e\u00edvaj\u00fa sa pre zariadenia s tzv. dvojitou izol\u00e1ciou (napr. nab\u00edja\u010dky mobiln\u00fdch telef\u00f3nov, lampy), kde nehroz\u00ed, \u017ee sa povrch stane vodiv\u00fdm.<\/p>\n\n\n\n
Pre\u010do existuj\u00fa rozdiely medzi krajinami? Kovov\u00fd v\u00fdstupok alebo otvor sl\u00fa\u017ei aj ako mechanick\u00e9 bezpe\u010dnostn\u00e9 zariadenie \u2013 zabra\u0148uje nespr\u00e1vnemu zasunutiu z\u00e1str\u010dky do z\u00e1suvky alebo do inej, potenci\u00e1lne nebezpe\u010dnej elektrickej siete.<\/p>\n\n\n\n
Vedeli ste, \u017ee napr\u00edklad vo Ve\u013ekej Brit\u00e1nii je tento uzem\u0148ovac\u00ed kol\u00edk e\u0161te dlh\u0161\u00ed ako ostatn\u00e9, tak\u017ee najprv otvor\u00ed ochrann\u00e9 kryty hlavn\u00fdch kontaktov?
