Surge tiv thaivrau ob qho tib si fais fab thiab cov kab teeb liab yog ib txoj hauv kev zoo kom txuag tau lub sijhawm poob qis, ua kom lub cev thiab cov ntaub ntawv muaj kev vam khom, thiab tshem tawm cov khoom puas tsuaj los ntawm kev hloov pauv thiab nce ntxiv.Nws tuaj yeem siv rau txhua hom chaw lossis thauj khoom (1000 volts thiab hauv qab).Cov hauv qab no yog cov piv txwv ntawm SPD siv hauv kev lag luam, kev lag luam, thiab thaj chaw nyob:

Cov txee tswj, programmable logic controllers, electronic motor controllers, equipment monitoring, lighting circuits, metering, medical equipment, critical loads, backup power, UPS, and HVAC equipment are all example of power distribution.

Circuits rau kev sib txuas lus, xov tooj los yog fax kab, cable TV pub, kev ruaj ntseg systems, tswb signaling circuits, chaw lom zem los yog stereo khoom, chav ua noj los yog cov khoom siv hauv tsev

SPDs tau txhais raws li hauv qab no los ntawm ANSI / UL 1449:

Hom 1: Kev sib txuas mus tas li, tsim los txuas rau theem nrab ntawm cov kev pabcuam hloov pauv mus rau kab ntawm kev pabcuam disconnect overcurrent ntaus ntawv (cov khoom pabcuam).Lawv lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv cov hluav taws xob hluav taws xob qhov hluav taws xob qhov hluav taws xob los ntawm cov hluav taws xob sab nraud vim yog hluav taws xob lossis hluav taws xob hluav taws xob hloov pauv lub txhab nyiaj.
Hom 2: Txuas mus tas li mus rau qhov chaw thauj khoom ntawm qhov kev pab cuam disconnect overcurrent ntaus ntawv (cov cuab yeej pabcuam), suav nrog cov chaw tsim khoom lag luam.Lub hom phiaj tseem ceeb ntawm cov surge protectors yog los tiv thaiv rhiab electronics thiab microprocessor-raws li loads los ntawm residual xob laim zog, motor-generated surges, thiab lwm yam sab hauv generated surge tshwm sim.

Hom 3: Thaum-the-Point-Of-Siv Los ntawm cov khoom siv hluav taws xob mus rau qhov chaw siv, SPDs yuav tsum tau tsim nrog tus neeg xyuas pib qhov ntev ntawm 10 meters (30 ko taw).SPDs uas yog hlua txuas, txuas ncaj qha rau hauv, thiab hom khoom txais yog cov piv txwv.

Hom 4: SPD (Cov Txheej Txheem Pom Zoo) Cov Khoom Sib Koom Tes - Cov khoom sib dhos no yog tsim los ntawm ib lossis ntau hom 5 SPD cov khoom, nrog rau kev sib txuas (sab hauv lossis sab nraud) lossis txhais tau tias dhau UL 1449, Tshooj 39.4 txwv tam sim no kuaj.Cov no yog cov tsis tiav SPD cov rooj sib txoos uas ib txwm muab tso rau hauv cov khoom siv kawg yog tias txhua qhov kev lees paub tau ua tiav.Hom 4 cov khoom sib dhos no tsis raug tso cai rau muab tso rau hauv qhov chaw ua ib leeg SPD vim tias lawv tsis tiav raws li SPD thiab yuav tsum tau kuaj ntxiv.Kev tiv thaiv overcurrent feem ntau xav tau rau cov khoom siv no.

Hom 5 SPD (Component Recognized) — Discrete tivthaiv surge tiv thaiv pab kiag li lawm, xws li MOVs, uas yuav tsum tau ntsia tau rau hauv ib tug luam Circuit Court board thiab txuas los ntawm lawv cov coj, los yog uas yuav tsum tau nyob rau hauv ib tug enclosure nrog mounting thiab wiring terminations.Hom 5 SPD cov khoom no tsis txaus raws li SPD thiab yuav tsum tau soj ntsuam ntxiv ua ntej muab tso rau hauv thaj chaw.Hom 5 SPDs feem ntau yog ua haujlwm hauv kev tsim thiab tsim cov SPDs lossis SPD cov rooj sib txoos.
