    Umhlahlandlela Wokukhetha Uchungechunge Lwesistimu Yokunikezwa Kwamandla e-SPD

    Ukufakwa kwe-SPD endaweni ngayinye yokuvikela umbani, ngokwezinga lokubukeka kukagesi okuphansi, kwenza ukuhlukaniswa kwemishini kagesi ngokuhambisana nesigaba se-over voltage, izinga layo le-insulation ukumelana ne-impulse voltage linganquma ukukhethwa kwe-SPD. Ngokwezinga lokubukeka kukagesi okuphansi, yenza ukuhlukaniswa kwemishini kagesi ngokuhambisana nesigaba se-over voltage njengezinga lesiginali, izinga lokulayisha, izinga lokusabalalisa kanye nezinga lokulawula, izinga lokunikezwa kwamandla. Izinga layo le-insulation ukumelana ne-impulse voltage yilawa: 1500V, 2500V, 4000V, 6000V. Ngokuya ngesikhundla sokufakwa kwemishini evikelwe, kuhlukile futhi kuhlukile kombane wamandla wendawo ehlukile yokuvikela umbani, ukuze kunqunywe indawo yokufaka ye-SPD yokuphakelwa kukagesi kanye nomthamo wokuqhekeka.
    Ibanga lokufaka phakathi kwe-SPD ngayinye yezinga akufanele libe ngaphezu kwamamitha ayi-10, ibanga phakathi kwe-SPD nemishini evikelwe kufanele libe lifushane ngangokunokwenzeka, kungabi ngaphezu kwamamitha ayi-10. Uma ngenxa yokulinganiselwa kwendawo yokufaka, ungakwazi ukuqinisekisa ibanga lokufaka, khona-ke kudingeka ufake ingxenye yokuhlukanisa phakathi kwe-SPD ngayinye yezinga, wenze i-SPD yesigaba esilandelayo ivikelwe yi-SPD yesigaba sangaphambilini. Kuhlelo lokunikezwa kwamandla kagesi oluphansi, ukuxhuma i-inductor kungafeza injongo yokuhlukanisa.
    I-SPD yesimiso sokukhetha imininingwane yesistimu yokunikezwa kwamandla
    I-voltage yokusebenza eqhubekayo ephezulu: inkulu kunemishini evikelwe, i-voltage yokusebenza eqhubekayo ephezulu kakhulu yesistimu.
    Uhlelo lwe-TT: Uc≥1.55Uo (Uo uhlelo lwe-voltage ephansi kuya ku-voltage yomugqa ongenalutho)
    Uhlelo lwe-TN: Uc≥1.15Uo
    Uhlelo lwe-IT: Uc≥1.15Uo(Uo uhlelo lwe-voltage ephansi ukuya ku-voltage yomugqa)
    Izinga Lokuvikela I-Voltage: ngaphansi kokufakwa kwe-insulation ukumelana ne-voltage yokushukuma kwemishini evikelwe
    Umthamo wokukhipha olinganiselwe: kunqunywa ngokwesimo sombani sendawo efakiwe kanye nendawo yokuvikela umbani.
