Pauk\u0161\u010diai, ramiai tupintys ant elektros laid\u0173, daugeliui atrodo tarsi \u201eapsaugoti\u201c nuo srov\u0117s. I\u0161 ties\u0173 \u010dia veikia ne ypatinga pauk\u0161\u010di\u0173 anatomija, o elementarios elektros taisykl\u0117s: srov\u0117 teka tik tada, kai atsiranda \u012ftampos skirtumas.<\/p>\n
Elektros srov\u0117 yra kr\u016bvio jud\u0117jimas laidininku, o ji \u201epasirenka\u201c keli\u0105, kuriuo lengviausia tek\u0117ti. Kad srov\u0117 pereit\u0173 per k\u016bn\u0105, jis turi atsidurti tarp dviej\u0173 skirtingos \u012ftampos ta\u0161k\u0173 ir u\u017edaryti grandin\u0119.<\/p>\n
Kod\u0117l tupint ant vieno laido srov\u0117 per pauk\u0161t\u012f neteka<\/p>\n
Kai pauk\u0161tis abiem kojomis lie\u010dia t\u0105 pat\u012f laid\u0105, abi jo kojos yra prakti\u0161kai tame pa\u010diame elektriniame potenciale. \u012etampos skirtumas tarp koj\u0173 b\u016bna labai ma\u017eas, tod\u0117l per pauk\u0161\u010dio k\u016bn\u0105 beveik n\u0117ra \u201evaromosios j\u0117gos\u201c, kuri priverst\u0173 srov\u0119 tek\u0117ti.<\/p>\n
Tokiu atveju elektra ir toliau teka pa\u010diu laidu, nes jis yra geras laidininkas, o pauk\u0161\u010dio k\u016bnas n\u0117ra \u201epatogesnis\u201c kelias. Pauk\u0161tis taip pat nelie\u010dia \u017eem\u0117s, tod\u0117l nesukuria tiesioginio kelio srovei nutek\u0117ti \u012f \u017eem\u0119.<\/p>\n
Kada pauk\u0161\u010dius visgi gali nutrenkti elektra<\/p>\n
Pavojus atsiranda tada, kai pauk\u0161tis vienu metu palie\u010dia du skirtingos \u012ftampos ta\u0161kus. Taip nutinka, jei jis viena koja atsiremia \u012f laid\u0105, o kita palie\u010dia kit\u0105 laid\u0105 arba \u012f\u017eemint\u0105 konstrukcij\u0105, pavyzd\u017eiui, stulp\u0105 ar skersin\u012f.<\/p>\n
Did\u017eiausia rizika kyla didesniems pauk\u0161\u010diams, nes j\u0173 sparn\u0173 mostas ar k\u016bno dydis lengviau \u201epasiekia\u201c antr\u0105 laid\u0105 ar metalin\u0119 atramos dal\u012f. D\u0117l \u0161ios prie\u017easties elektros tinkluose naudojami \u012fvair\u016bs sprendimai, ma\u017einantys trump\u0173 sujungim\u0173 tikimyb\u0119: izoliatoriai, apsauginiai gaubtai ir atbaidymo priemon\u0117s ant atram\u0173.<\/p>\n
Kod\u0117l \u017emogui situacija kitokia<\/p>\n
\u017dmogus da\u017eniausiai gauna sm\u016bg\u012f, kai palie\u010dia laid\u0105 b\u016bdamas ant \u017eem\u0117s ar kitos laid\u017eios dangos. Tuomet k\u016bnas tampa grandin\u0117s dalimi tarp auk\u0161tesn\u0117s \u012ftampos ta\u0161ko ir \u017eem\u0117s, tod\u0117l srov\u0117 gali tek\u0117ti per audinius, sukeldama sunkius su\u017ealojimus.<\/p>\n
Net ir trumpas kontaktas gali b\u016bti pavojingas, nes lemiamas veiksnys yra ne tik \u012ftampa, bet ir per k\u016bn\u0105 tekanti srov\u0117 bei kontakto s\u0105lygos. Tod\u0117l elektros \u012frengini\u0173 ir oro linij\u0173 artumoje saugos taisykl\u0117s galioja nepriklausomai nuo to, kaip \u201esaugiai\u201c atrodo laidai i\u0161 \u0161alies.<\/p>\n","protected":false},"excerpt":{"rendered":"
