Taw qhia
EPD series T1T2 xob laim tiv thaiv SPD yog lub hom phiaj tsim los tiv thaiv cov khoom siv hluav taws xob thiab cov tshuab tiv thaiv hluav taws xob, feem ntau hu ua surges lossis transient voltages. Cov surges no tuaj yeem tshwm sim los ntawm ntau qhov chaw, suav nrog xob laim, hluav taws xob hloov pauv, kev hloov pauv, lossis lwm yam cuam tshuam hluav taws xob.
Lub hom phiaj tseem ceeb ntawm EPD series T1T2 xob laim tiv thaiv SPD yog txhawm rau hloov pauv qhov hluav taws xob ntau dhau thiab txwv qhov nce mus rau qhov chaw nyab xeeb, yog li tiv thaiv qhov hluav taws xob ntau dhau los ntawm kev ncav cuag thiab ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob thiab cov khoom siv sib txuas.
Ua raws li SPD Chav Kawm I + II (Class B + C) kev faib tawm raws li cov qauv xws li IEC61643-11 thiab GB 18802.11, EPD series T1T2 Kev tiv thaiv xob laim SPD ntiav cov khoom siv qib siab xws li hlau-oxide varistors (MOV) lossis Gas Discharge Tubes (GDT) kom nqus los yog hloov cov hluav taws xob ntau dhau. Cov khoom no muab txoj hauv kev qis-impedance rau surge tam sim no, tam sim ntawd teb rau surges thiab diverting lub zog dhau mus rau hauv av los yog ib qho chaw nruab nrab, yog li ua kom muaj kev tiv thaiv ntawm cov khoom sib txuas.
Tsis tas li ntawd, EPD series T1T2 xob laim tiv thaiv SPD muaj cov txiaj ntsig ntxiv tshaj li kev tiv thaiv kev kub ntxhov. Nws txhim khu kev ntseeg tau thiab siv tau ntev ntawm cov tshuab hluav taws xob los ntawm kev txo cov kev puas tsuaj ntawm kev nce siab, txo qis qis qis, thiab txo qhov kev xav tau ntawm kev kho nqi kim lossis hloov khoom siv.
Nrog nws cov qauv tsim muaj zog, ua raws li cov qauv thoob ntiaj teb, thiab kev siv cov khoom tiv thaiv siab heev, EPD series T1T2 xob laim tiv thaiv SPD muab kev daws teeb meem los tiv thaiv hluav taws xob. Nws txhawb kev ua haujlwm tsis cuam tshuam ntawm cov khoom siv hluav taws xob rhiab heev, txhawb kev ntseeg siab thiab kev thaj yeeb ntawm lub siab hauv cov neeg siv.
Feature
● 10/350μs, 8/20μs qhov sib txawv
● Ib-ncej xob laim tam sim no suppressor, yooj yim txuas
● Siv lub tshuab hermetically kaw GDT, xa cov txiaj ntsig zoo hauv kev tua cov dej ntws tom ntej
● Remarkably tsawg voltage tiv thaiv pib
● Twin terminals rau kev hloov pauv mus rau qhov sib npaug lossis cov kev sib txuas (V-shaped) kev xaiv
● Ntau hom kev sib txuas xaiv rau ob qho tib si conductors thiab busbars
● Hloov cov xim ntawm qhov taw qhia qhov rais mus rau xim liab thaum kuaj pom qhov yuam kev, thaum tseem muab lub tswb nrov nyob rau hauv ib lub sijhawm.
● Rau kev siv MOV ua haujlwm siab thiab siab tshaj 10/350 25kA
