Surge Protective Devices(Direct Current SPD)

Lakop na Aplikasyon

Say SPD et matukoy ed amin a klase na low-voltage distribution systems ya walay grid voltage ya abeba nen 1000 volts tan frequency ya 50/60HZ, singa say post tan telecommunications, railways, financial systems, oil fields, high-rise buildings, kaabungan tan opisina. Pian naprotektaan iray electrical appliances (singa saray computer, instrumento tan kagawaan, kagawaan ed abung, tan arum ni) na sarayan manguusar na kuryente manlapud kirmat, transient overvoltage tan arum niran surge overvoltage damage. Seguroen so kaligenan na kagawaan tan personal. Saya so sankaabigan ya proteksion ed sobran boltahe.

Manunan istruktura tan prinsipyo na pantratrabaho

Diad three-phase four-wire system, saray protektor et akakonekta ed baetan na taloran phase wires tan sakey ya neutral wire ed ground wire (nengnengen so pigura ed leksab). Diad normal iran sirkumstansya, say protektor et walad Levin state, tan no say power grid et napapaarap ed surge overvoltage lapud kirmat odino arum niran rason. Say protektor et maples ya na-on ed loob na nanosecond time, ya mangiloob na surge overvoltage ed dalin, kanian naprotektaan so electrical equipment ed power grid. No say surge overvoltage et onlabas ed protektor tan naandi, say protektor et ompawil lamet ed high resistance state. Pian ag naapektoan so normal ya operasyon na power grid.
