Dab tsi yog qhov surge protector? Surge protector, tseem hu ua xob tiv thaiv, yog ib qho khoom siv hluav taws xob uas muab kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov cuab yeej siv, thiab cov kab sib txuas lus. Thaum ib tug spike tam sim no los yog voltage yog dheev generated nyob rau hauv hluav taws xob Circuit Court los yog kev sib txuas lus Circuit Court vim muaj kev cuam tshuam sab nraud, lub surge protector tuaj yeem ua thiab shunt nyob rau hauv ib tug heev luv luv lub sij hawm, thiaj li yuav tiv thaiv lub surge los ntawm kev puas tsuaj rau lwm yam khoom nyob rau hauv lub Circuit Court. Vim li cas peb thiaj xav tau tus tiv thaiv surge? Kev puas tsuaj xob laim yog ib qho kev puas tsuaj loj tshaj plaws. Txhua xyoo, muaj countless casualties thiab khoom poob los ntawm xob laim puas tsuaj nyob rau hauv lub ntiaj teb no. Nrog daim ntawv thov loj ntawm cov khoom siv hluav taws xob thiab microelectronic integrated, muaj yog ntau thiab ntau puas rau cov tshuab thiab khoom siv los ntawm xob laim overvoltages thiab xob laim electromagnetic pulses. Yog li ntawd, nws yog ib qho tseem ceeb heev los daws qhov xob laim teeb meem tiv thaiv kev puas tsuaj ntawm cov tsev thiab cov ntaub ntawv xov xwm hluav taws xob sai li sai tau ua tau. Nrog rau qhov yuav tsum tau muaj zog ntxiv ntawm cov cuab yeej muaj feem xyuam rau kev tiv thaiv xob laim, lub installation ntawm surge protectors los suppress lub surge thiab instantaneous overvoltage rau txoj kab, thiab cov overcurrent ntawm cov kab tawm tau dhau los ua ib feem tseem ceeb ntawm niaj hnub xob tiv thaiv technology. Lub surge protector ua haujlwm li cas? Lub hauv paus ntsiab lus ua haujlwm ntawm peb cov khoom yog: thaum tsis muaj overvoltage, cov khoom nyob rau hauv lub xeev tawm, thiab kev tiv thaiv yog infinite. Thaum muaj overvoltage nyob rau hauv lub system, lub cov khoom yog nyob rau hauv lub xeev kaw thiab cov kuj yog infinitely me me, thiab lub internal Cheebtsam yuav clamp lub voltage nyob rau hauv ib tug tej yam ntau yam. , Tam sim no ntws los ntawm kab yuav absorbed thiab tawm. Tom qab qhov kev tso tawm tiav lawm, cov khoom rov qab los mus rau lub xeev muaj zog heev (lub xeev disconnected) kom nws yuav tsis muaj lwm yam cuam tshuam rau cov khoom siv. Dab tsi yog qhov tseem ceeb ntawm cov surge protector? 1.Qhov max txuas ntxiv kev khiav hauj lwm voltage (Uc): Hais txog tus nqi siab tshaj plaws ntawm AC voltage lossis DC voltage uas tuaj yeem siv txuas ntxiv mus rau SPD. 2.Max tawm tam sim no (Imax): Xa mus rau qhov siab tshaj tawm tam sim no uas SPD tuaj yeem ua tau tiv taus ib zaug siv 8/20μs tam sim no nthwv dej los cuam tshuam rau SPD. 3.Minimun tso tawm tam sim no (Nyob rau hauv): Xa mus rau qhov tso tawm tam sim no uas SPD tuaj yeem ua haujlwm ib txwm 4.Kev tiv thaiv qib: Cov nqi siab tshaj plaws ntawm qhov hluav taws xob nruab nrab ntawm cov terminals ntawm SPD hauv muaj ib qho impulsive overvoltage.lt yog ib qho tseem ceeb parameter kom raug xaiv qhov SPD; account ntawm nws yuav tsum tau coj nyob rau hauv relation mus rau lub impulse voltage ntawm cov khoom yuav tsum tau tiv thaiv. THOR ua dab tsi? Txij li thaum nws tsim, Thor tau ua raws li lub ntiaj teb xob laim Kev tiv thaiv tus qauv (IEC61643-1) thiab tau cog lus rau kev tsim khoom thiab kev tshawb fawb thiab kev loj hlob ntawm surge protectors. Cov khoom muaj xws li lub zog hluav taws xob tiv thaiv hauv tsev, photovoltaic surge protectors, industrial surge protectors, thiab tes hauj lwm surge protectors, teeb liab surge protectors, thiab lwm yam los muab cov neeg siv khoom nrog kev xaiv zoo dua rau xob laim cov khoom tiv thaiv.
