Wy\u0142\u0105cznik r\u00f3\u017cnicowopr\u0105dowy (RCD) jest powszechnie stosowanym urz\u0105dzeniem elektrycznym s\u0142u\u017c\u0105cym do wykrywania obecno\u015bci wyciek w obwodzie<\/span><\/a> i od\u0142\u0105czaj\u0105 obw\u00f3d natychmiast po wykryciu up\u0142ywu.

W szczeg\u00f3lno\u015bci zabezpieczenie up\u0142ywowe 1P ma tylko jedno urz\u0105dzenie zabezpieczaj\u0105ce przed up\u0142ywem, kt\u00f3re jest zwykle instalowane w obwodzie jednofazowym. Mo\u017ce wykry\u0107, czy w obwodzie wyst\u0119puje up\u0142yw, ale mo\u017ce chroni\u0107 tylko jeden obw\u00f3d. Na przyk\u0142ad, gdy u\u017cywasz piekarnika w kuchni, je\u015bli w tym samym czasie wyst\u0105pi wyciek w obwodzie pralki, zabezpieczenie przed wyciekiem 1P nie mo\u017ce go chroni\u0107, poniewa\u017c mo\u017ce chroni\u0107 tylko jeden obw\u00f3d.<\/p>

Zabezpieczenie przed up\u0142ywem 2P posiada dwa urz\u0105dzenia zabezpieczaj\u0105ce przed up\u0142ywem, kt\u00f3re mog\u0105 chroni\u0107 dwa obwody jednocze\u015bnie. Gdy w obwodzie wyst\u0105pi wyciek, zabezpieczenie przed wyciekiem natychmiast odetnie zasilanie obwodu, aby zapobiec dalszemu rozprzestrzenianiu si\u0119 wycieku. Je\u015bli wyciek wyst\u0105pi w dw\u00f3ch obwodach w tym samym czasie, zabezpieczenie przed wyciekiem 2P mo\u017ce r\u00f3wnie\u017c odci\u0105\u0107 oba obwody w tym samym czasie, chroni\u0105c w ten spos\u00f3b bezpiecze\u0144stwo ludzi.<\/p>

Poniewa\u017c wy\u0142\u0105cznik r\u00f3\u017cnicowopr\u0105dowy 1P wymaga tylko jednego urz\u0105dzenia ochrony r\u00f3\u017cnicowopr\u0105dowej, a wy\u0142\u0105cznik r\u00f3\u017cnicowopr\u0105dowy 2P wymaga dw\u00f3ch urz\u0105dze\u0144 ochrony r\u00f3\u017cnicowopr\u0105dowej, wi\u0119c jego koszt jest wy\u017cszy. Ponadto zabezpieczenie r\u00f3\u017cnicowopr\u0105dowe 2P wymaga wi\u0119cej miejsca do zainstalowania, poniewa\u017c wymaga dw\u00f3ch przewod\u00f3w elektrycznych, podczas gdy zabezpieczenie r\u00f3\u017cnicowopr\u0105dowe 1P wymaga tylko jednego przewodu elektrycznego.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Po drugie, metody wyzwalania zabezpieczenia up\u0142ywowego 1P i zabezpieczenia up\u0142ywowego 2P s\u0105 r\u00f3wnie\u017c r\u00f3\u017cne. Zabezpieczenie up\u0142ywowe 1P mo\u017ce wykrywa\u0107 tylko up\u0142yw jednobiegunowy, to znaczy po wp\u0142yni\u0119ciu pr\u0105du do urz\u0105dzenia elektrycznego z zasilacza, wyp\u0142ywa on z jednego bieguna urz\u0105dzenia elektrycznego (zwykle z przewodu pod napi\u0119ciem) i powraca do drugiego bieguna zasilacza (zwykle z przewodu neutralnego). Dlatego te\u017c, je\u015bli pr\u0105d wp\u0142ywa do urz\u0105dzenia elektrycznego z przewodu neutralnego, a nast\u0119pnie wyp\u0142ywa z przewodu pod napi\u0119ciem, zabezpieczenie up\u0142ywowe 1P nie mo\u017ce wykry\u0107 up\u0142ywu. Zabezpieczenie up\u0142ywowe 2P mo\u017ce wykrywa\u0107 up\u0142yw dwubiegunowy, co oznacza, \u017ce niezale\u017cnie od tego, z kt\u00f3rego bieguna p\u0142ynie pr\u0105d, mo\u017ce on zosta\u0107 wykryty.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Wreszcie, pr\u0105d znamionowy i znamionowy czas dzia\u0142ania zabezpieczenia up\u0142ywowego 1P i zabezpieczenia up\u0142ywowego 2P s\u0105 r\u00f3wnie\u017c r\u00f3\u017cne. Og\u00f3lnie rzecz bior\u0105c, pr\u0105d znamionowy i znamionowy czas dzia\u0142ania zabezpieczenia up\u0142ywowego 2P b\u0119d\u0105 wy\u017csze ni\u017c w przypadku zabezpieczenia up\u0142ywowego 1P, poniewa\u017c musi ono obs\u0142ugiwa\u0107 wi\u0119cej obwod\u00f3w.
