Lub luag haujlwm ntawm surge protector

Surge, (Surge Protection Device) yog ib qho khoom siv tseem ceeb hauv kev tiv thaiv hluav taws xob hluav taws xob.Lub luag haujlwm ntawm tus tiv thaiv hluav taws xob yog txwv tsis pub dhau qhov hluav taws xob tam sim ntawd nkag mus rau hauv cov kab hluav taws xob thiab cov teeb liab kis tau tus mob nyob rau hauv qhov hluav taws xob ntau yam uas cov cuab yeej siv los yog lub cev muaj peev xwm tiv taus, los yog tso tawm cov hluav taws xob muaj zog tam sim no rau hauv av los tiv thaiv cov cuab yeej tiv thaiv lossis qhov system. los ntawm kev puas tsuaj.puas los ntawm kev cuam tshuam.

Surge protector txoj cai

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus tiv thaiv surge yog raws li hauv qab no: lub surge protector feem ntau yog ntsia ntawm ob qho kawg ntawm cov cuab yeej tiv thaiv thiab hauv av.Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, lub surge protector nthuav tawm ib tug siab impedance rau lub cev muaj zog zaus voltage, thiab yuav luag tsis muaj tam sim no ntws los ntawm nws, uas yog sib npaug rau ib tug qhib Circuit Court;Thaum ib qho kev hloov pauv dhau los tshwm sim hauv qhov system, tus tiv thaiv surge yuav teb rau cov kev hloov pauv ntau zaus.Qhov voltage nthuav tawm qhov impedance tsawg, sib npaug rau luv luv-circuiting cov khoom tiv thaiv.

1. Hloov hom: Nws txoj hauv kev ua haujlwm yog tias thaum tsis muaj tam sim no overvoltage, nws nthuav tawm qhov siab impedance, tab sis thaum nws teb rau xob laim instantaneous overvoltage, nws impedance mam li nco dheev hloov mus rau tus nqi qis, cia xob laim tam sim no dhau mus.Thaum siv xws li cov khoom siv, cov cuab yeej muaj xws li: cov pa tawm, cov pa tawm roj, thyristors, thiab lwm yam.

2. Voltage-limiting type: Nws txoj hauv kev ua haujlwm yog qhov siab impedance thaum tsis muaj tam sim no overvoltage, tab sis nws impedance tseem yuav txo qis nrog qhov nce ntawm surge tam sim no thiab voltage, thiab nws cov yam ntxwv tam sim no-voltage yog qhov tsis muaj zog.Cov cuab yeej siv rau cov khoom siv xws li: zinc oxide, varistor, suppressor diode, avalanche diode, thiab lwm yam.

3. hom shunt lossis choke hom

Shunt hom: nyob rau hauv parallel nrog cov cuab yeej tiv thaiv, nws nthuav tawm impedance qis rau xob laim pulses thiab siab impedance rau ib txwm ua haujlwm zaus.

Choke hom: Nyob rau hauv series nrog cov khoom tiv thaiv, nws nthuav tawm siab impedance rau xob laim pulses thiab tsis tshua muaj impedance rau ib txwm ua haujlwm zaus.

Cov cuab yeej siv xws li cov khoom siv xws li: choke coils, high-pass lim, low-pass filters, 1/4 wavelength short-circuiters, thiab lwm yam.
