Cov Khoom Siv Tiv Thaiv Surge (Direct Current SPD)

Scope ntawm Daim Ntawv Thov

SPD yog tsim rau txhua yam ntawm cov tshuab faib hluav taws xob qis nrog lub zog hluav taws xob qis dua 1000 volts thiab zaus ntawm 50/60HZ, xws li kev xa ntawv thiab kev sib txuas lus, kev tsheb ciav hlau, cov txheej txheem nyiaj txiag, cov chaw roj, cov tsev siab, cov tsev thiab cov chaw ua haujlwm. Txhawm rau tiv thaiv cov khoom siv hluav taws xob (xws li cov khoos phis tawj, cov twj paj nruag thiab cov khoom siv, cov khoom siv hauv tsev, thiab lwm yam) ntawm cov neeg siv hluav taws xob no los ntawm kev tawm tsam xob laim, kev hloov pauv hluav taws xob ib ntus thiab lwm yam kev puas tsuaj los ntawm kev hloov pauv hluav taws xob. Xyuas kom meej cov khoom siv thiab kev nyab xeeb ntawm tus kheej. Nws yog ib qho khoom siv tiv thaiv hluav taws xob zoo tagnrho.

Cov qauv tseem ceeb thiab txoj cai ua haujlwm

Hauv peb-theem plaub-xaim system, cov neeg tiv thaiv tau txuas ntawm peb-theem xov hlau thiab ib txoj xov hlau nruab nrab rau hauv av xov hlau (saib daim duab hauv qab no). Nyob rau hauv qhov xwm txheej ib txwm muaj, tus neeg tiv thaiv nyob rau hauv Levin lub xeev, thiab thaum lub hwj chim grid raug rau surge overvoltage vim xob laim lossis lwm yam laj thawj. Tus neeg tiv thaiv yuav raug qhib sai sai hauv nanosecond lub sijhawm, qhia surge overvoltage rau hauv av, yog li tiv thaiv cov khoom siv hluav taws xob ntawm lub hwj chim grid. Thaum lub surge overvoltage hla dhau tus neeg tiv thaiv thiab ploj mus, tus neeg tiv thaiv rov qab mus rau lub xeev tiv thaiv siab dua. Yog li ntawd kom tsis txhob cuam tshuam rau kev ua haujlwm ib txwm ntawm lub hwj chim grid.
