Shielded T Rear Surge Arrester

Lub luag haujlwm ntawmcov cuab yeej tiv thaiv kev coyog los tiv thaiv ntau yam khoom siv hluav taws xob hauv lub zog fais fab los ntawm kev puas tsuaj los ntawm xob laim overvoltage, kev ua haujlwm overvoltage, thiab lub zog zaus transient overvoltage. Cov hom tseem ceeb ntawm xob laim arresters yog cov qhov sib txawv tiv thaiv, valve arresters thiab zinc oxide arresters. Qhov sib txawv tiv thaiv feem ntau yog siv los txwv qhov atmospheric overvoltage, thiab feem ntau yog siv rau kev tiv thaiv ntawm cov kab nkag ntawm lub zog faib hluav taws xob, kab thiab substation. Valve-hom arresters thiab zinc oxide arresters yog siv rau kev tiv thaiv ntawm substations thiab cov chaw fais fab. Hauv 500kV thiab hauv qab no systems, lawv feem ntau yog siv los txwv qhov atmospheric overvoltages. Hauv ultra-high voltage systems, lawv kuj tseem yuav siv los txwv qhov sab hauv overvoltages lossis ua sab hauv overvoltages. Kev tiv thaiv thaub qab.

Txij li thaumcov khoom siv tiv thaiv kev cofeem ntau ua haujlwm sab nraum zoov, lawv yuav tsum muaj zog tiv taus kev poob, tiv taus kev poob siab thiab kev ua haujlwm tsis muaj dej.

Shielded T Rear Surge Arrestermuab kev tiv thaiv over-current txhim khu kev qha rau cov khoom siv hluav taws xob. Nws cov khoom tseem ceeb siv cov zinc oxide resistors, uas txhim kho cov yam ntxwv volt-ampere ntawm cov resistors thiab ua rau muaj peev xwm khaws cia overvoltage ntau dua piv rau cov khoom siv silicon carbide arresters ib txwm muaj; Nws feem ntau yog siv ua ke nrog European 630A pem hauv ntej connector los muab kev tiv thaiv overvoltage rau lub zog fais fab.
