Surge Protective Devices tuaj yeem muab faib ua ke raws li qib kev tiv thaiv, kev ua haujlwm hauv paus ntsiab lus, daim ntawv thov scenario, thiab kev teeb tsa txoj haujlwm, ua kom tiav cov kev faib tawm kom haum rau cov kev tiv thaiv hluav taws xob sib txawv. Qhov kev faib ua tiav yog raws li hauv qab no:
1. Kev faib tawm los ntawm qib kev tiv thaiv IEC (feem ntau cov kev lag luam kev faib tawm).
Hom 1 SPD: Kuj tseem hu ua xob laim tam sim no ntes. Nws yog ntsia rau ntawm tag nrho cov hluav taws xob nkag mus kawg ntawm cov tsev, chav faib hluav taws xob, thiab qhov hluav taws xob substation. Nws yog tsuas yog siv los tso cov hluav taws xob hluav taws xob loj loj tam sim no thiab muaj lub peev xwm loj heev, tsim nyog rau kev tiv thaiv hluav taws xob muaj zog.
Hom 2 SPD: Kuj tseem hu ua overvoltage suppressor. Nws tau nruab rau hauv cov khoom siv hluav taws xob thib ob ntawm cov tsev thiab kev cob qhia. Nws lees paub txoj haujlwm thib ob ntawm kev txo qis ntawm cov hluav taws xob seem thiab cov phiajcim hloov pauv, nrog kev sib npaug ntawm lub peev xwm thiab qhov hluav taws xob clamping kev ua tau zoo, uas yog hom SPD siv dav tshaj plaws.
Hom 3 SPD: Kuj hu ua davhlau ya nyob twg precision protector. Nws yog ntsia rau pem hauv ntej kawg ntawm precision hluav taws xob khoom thiab ntse terminals. Nws nta ultra- tsis tshua muaj hluav taws xob residual siab thiab siab precision clamping kev ua tau zoo, aiming kom tshem tawm me me residual surges thiab tiv thaiv rhiab hluav taws xob Cheebtsam.
2. Kev faib tawm los ntawm kev ua haujlwm
Varistor-hom SPD: Txais cov hlau oxide varistors ua cov ntsiab lus tseem ceeb, nrog cov lus teb ceev ceev thiab tus nqi qis, tsim nyog rau feem ntau cov pa hluav taws xob tiv thaiv qhov xwm txheej.
Gas discharge tube-hom SPD: Siv cov pa roj tawm hauv paus ntsiab lus rau kev tso tawm, nrog rau tam sim no loj thiab muaj zog tiv thaiv xob laim, feem ntau yog siv rau kev tiv thaiv xob laim.
Semiconductor-hom SPD: Txais TVS diode Cheebtsam, nrog ultra- teb sai thiab siab precision, haum rau cov teeb liab Circuit Court thiab precision khoom tiv thaiv.
3. Kev faib tawm los ntawm daim ntawv thov scenario
Pej xeem tsev neeg SPD: me me, muaj peev xwm tawm tsawg, tsim nyog rau cov khoom siv hluav taws xob hauv tsev, cov khoom siv hauv tsev, thiab cov khoom siv hluav taws xob hauv tsev.
Muaj SPD: Muaj peev xwm tawm tau, ib puag ncig tiv thaiv, thiab kev saib xyuas muaj nuj nqi, tsim nyog rau kev lag luam hluav taws xob, khoom siv hluav taws xob, thiab sab nraum zoov engineering systems.
Teeb liab SPD: Tshwj xeeb rau cov kab sib txuas, cov kab sib txuas lus, thiab cov cuab yeej teeb liab kab, tiv thaiv cov teeb liab kis tau los ntawm kev cuam tshuam thiab kev puas tsuaj.
4. Kev faib tawm los ntawm kev teeb tsa
Module-hom SPD: Rail-mounted modular tsim, yooj yim installation thiab hloov, yooj yim rau kev txij nkawm tom qab, dav siv hauv cov khoom siv hluav taws xob.
Integrated SPD: Integral sealing qauv, siab tiv thaiv qib, haum rau hnyav sab nraum zoov thiab ntub dej.
