Isetyenziselwa ukukhuselwa kokunyuka kweesekethe zombane, izixhobo zokubonelela ngombane kunye nezibuko zamandla zezinye izixhobo zombane; cinezela i-overvoltage edlulayo, ukukhupha impulse current, kunye nokuseka inkqubo ye-equipotential. (Isixhobo sokukhusela umbane seNqanaba loku-1. Isixhobo sokukhusela umbane seNqanaba lesi-2. Isixhobo sokukhusela umbane seNqanaba lesi-3.)
Isixhobo sokukhusela umbane weSignali sisekelwe kwiimpawu zenkqubo yesignali, ineenzuzo zelahleko encinci yokufaka, isantya sokuphendula ngokukhawuleza, i-clamping echanekileyo, i-voltage ephantsi eshiyekileyo, njl., kunye nokusebenza okuphezulu kokuhambisa. (Isixhobo sokukhusela umbane se-Network-in-one. Lawula isixhobo sokukhusela umbane womqondiso. Isixhobo sokukhusela umbane womqondiso wevidiyo. Isixhobo sokukhusela umbane wophawu lomsindo. Isixhobo sokukhusela umbane we-antenna feed).
Idizayinwe ngokuhambelana neemfuno zokhuseleko lombane kwiibhokisi zanamhlanje zemultimedia junction, inokukhusela izixhobo zonxibelelwano lwangaphakathi kunye nezixhobo zemultimedia kumonakalo owenziwe ngumbane.
I-disconnector yangaphandle ekhethekileyo (SSD / SCB) yokukhusela i-surge, ngokuzinza okulungileyo kunye nokuthembeka okuphezulu. (Ikhusela umkhuseli)
Iwaranti yemveliso ibalulekile
Umbono weMveliso
Umgca we-N kunye ne-PE yenkqubo idibaniswe kumgca we-PEN ukusuka kwicala eliphantsi le-voltage ye-transformer. Kule ndawo, kuphela (3P) umkhuseli wokunyuka kufuneka afakwe phakathi komgca wesigaba kunye nomgca we-PEN. Emva kokungena kwibhokisi enkulu yokusabalalisa isakhiwo, Umgca we-PEN uhlukaniswe ube ngumgca we-N ^ Umgca we-PE kunye ne-wiring ezimeleyo. Umgca we-PEN uqhagamshelwe kwi-equipotential grounding busbar kwisakhiwo ukuxhuma emhlabeni.
Umgca we-N kunye nomgca we-PE wenkqubo uqhagamshelwe kuphela ekupheleni kwe-outlet ye-low-voltage side ye-transformer kwaye idibene nomhlaba. Ngaphambi kokungena kwibhokisi yokusabalalisa ngokubanzi kwesakhiwo, umgca we-N kunye nomgca we-PE uxhomekeke ngokuzimeleyo, kwaye umgca wesigaba kunye nomgca we-PE kufuneka udibanise Faka umkhuseli wokunyuka.
Umgca we-N wale nkqubo usekelwe kuphela kwindawo engathathi hlangothi ye-transformer, kwaye umgca we-N kunye nomgca we-PE uhlukaniswe ngokungqongqo. Ngoko ke, kuyimfuneko ukufaka umkhuseli wokunyuka phakathi komgca wesigaba kunye nomgca we-N, kwaye umkhuseli wokutshitsha wohlobo lokutshintsha uvame ukufakwa phakathi komgca we-N kunye nomgca we-PE.
Indawo engathathi hlangothi ye-transformer yale nkqubo ayigxilwanga, kwaye kukho ucingo lwe-N kumgca.
