Surge Protection Model Equipotential Connector
Surge Protection Model Equipotential Connector
Lub network POE surge protector yog siv rau kev tiv thaiv ntawm AC / DC fais fab mov thiab network teeb liab ntawm POE network cov cuab yeej, yog li zoo absorbing lub zog cuam tshuam los ntawm surge, thiab qhia lub zog rau hauv lub ntiaj teb los ntawm lub grounding cable. Kev tsim kho ntau yam kev sib xyaw ua ke txo cov nqi tiv thaiv thiab teeb meem kev teeb tsa, txuag qhov chaw teeb tsa, thiab txhim kho kev tiv thaiv zoo ntawm lub koob yees duab.
Lub teeb liab ntes hluav taws xob yog ib hom kev tiv thaiv hluav taws xob, uas yog ib qho tseem ceeb ntawm kev tiv thaiv sab hauv. Niaj hnub no txoj kev loj hlob sai ntawm cov ntaub ntawv thev naus laus zis, daim ntawv thov ntawm cov teeb liab tiv thaiv hluav taws xob yog ntau thiab ntau dua, thiab tau txais txiaj ntsig zoo los ntawm txhua tus. Muaj ntau ntau hom teeb liab teeb liab ntes, uas yuav tsum tau ua kom haum raws li cov kev xav tau sib xws.
Cov ntaub ntawv teeb liab hluav taws xob tiv thaiv qib qis cov ntaub ntawv teeb liab ib feem, suav nrog cable TV xob laim tiv thaiv ntaus ntawv, twisted khub kis tau tus mob xob laim tiv thaiv ntaus ntawv, kev sib txuas lus teeb liab kab hluav taws xob tiv thaiv ntaus ntawv, satellite receiver kav hlau txais xov hluav taws xob tiv thaiv ntaus ntawv, tus tswv tsev thiab kev pabcuam hluav taws xob tiv thaiv ntaus ntawv
(1) Kev tiv thaiv thawj zaug ntawm lub teeb liab
Twisted khub teeb liab tiv thaiv (overvoltage tiv thaiv plug) tiv thaiv teeb liab system thiab khoom siv. Qhov ntsuas hluav taws xob yog 100vac / DC, thiab qhov siab tshaj tawm tam sim no ismax ntawm txhua kab yog 10kA (8 ~ 20 A) μ s) Lub sijhawm teb tsawg dua 10ns.
Rau cov kab hluav taws xob, cov kab teeb liab (analog thiab digital), piv txwv li, 110VAC / DC rau cov khoom siv hauv xov tooj; Tswj thiab ntsuas kab thiab cov ntaub ntawv kab yog 12V DC / 8V AC thiab 24V DC / 15V AC. Lub teeb liab teeb liab ntes AD / kz-24 yuav tsum raug ntsia. LH series surge tiv thaiv ntaus ntawv (hauv luv: SPD, alias: surge protector, surge arrester) yog tsim rau cov lag luam xws li tsoom fwv nyiaj txiag thiab kev tuav pov hwm ntawm lawv lub computer host, davhlau ya nyob twg lub computer, modem server thiab transceiver uas cable transmission ntawm 9,15 pim los yog cable tej thaj chaw deb-sensing, tej thaj chaw deb-teting ntawm D style interface device.lt'll nyhuv txo cov teeb meem ntawm software thiab kho vajtse rau los poob siab mem tes

1. Ua ntej lub surge protector hlua txuas nrog cov cuab yeej tiv thaiv, lub hwj chim yuav tsum raug muab tua, thiab kev ua neej nyob yog txwv nruj heev.
2. Tso rau hauv cov kab ntawm cov kab ntawm cov khoom tiv thaiv, kev sib txuas ntawm kev sib txuas yuav tsum txhim khu kev qha, thiab cov khoom tiv thaiv surge muaj cov khoom nkag (IN) thiab cov zis (OUT) cov cim. Cov zis davhlau ya nyob twg txuas nrog cov khoom tiv thaiv, tsis txhob txuas rov qab. Txwv tsis pub, lub surge protector yuav puas thaum xob laim tawm tsam, thiab cov khoom siv yuav tsis muaj kev tiv thaiv zoo (saib rau hauv daim duab qhia kev teeb tsa thiab xov hluav taws xob).
3. Cov xaim hauv av (PE) yuav tsum muaj kev ntseeg siab rau hauv av xaim ntawm kev tiv thaiv surge, thiab qhov ntev yuav tsum yog qhov luv tshaj plaws kom ua tiav qhov kev tiv thaiv zoo tshaj plaws.
4. Cov khoom siv yuav tsum tau muab tshem tawm thaum txhim kho cov xaim hauv av kom tsis txhob muaj kev puas tsuaj rau cov khoom siv vim qhov kev taw qhia ntawm cov hluav taws xob muaj zog xws li hluav taws xob vuam los ntawm cov xaim hauv av kawg.
5. Txuas cov xaim hauv av ntawm lub surge protector thiab lub plhaub hlau ntawm cov khoom siv rau hauv av collector bar.
6. Thaum lub sij hawm siv, lub surge protector yuav tsum tau kuaj tsis tu ncua. Yog tias nws ua tsis tau, nws yuav tsum tau kho lossis hloov lub sijhawm kom muaj kev nyab xeeb ntawm cov cuab yeej tiv thaiv.
7. Cov uas tsis yog kws tshaj lij yuav tsum tsis txhob cuam tshuam nws.
