Tais tens&otilde;es anormais s&atilde;o muitas vezes causadas por ataques de rel&acirc;mpagos, descargas de raios atmosf&eacute;ricos, contato acidental entre linhas de energia e comunica&ccedil;&otilde;es, aumento inesperado das tens&otilde;es de alimenta&ccedil;&atilde;o da instala&ccedil;&atilde;o como resultado de uma opera&ccedil;&atilde;o incorreta e apar&ecirc;ncia de tens&atilde;o superior ao normal durante as opera&ccedil;&otilde;es de comuta&ccedil;&atilde;o.

Ele &eacute; usado para ser conectado em paralelo entre a linha e linha de equipamento, ou entre a linha e o ch&atilde;o (mostra como figuras de fundo). Se a sobretens&atilde;o n&atilde;o atinge a tens&atilde;o de a&ccedil;&atilde;o da GDT, o tubo de descarga de g&aacute;s cer&acirc;mico estar&aacute; em estado de alta resist&ecirc;ncia. Se a sobretens&atilde;o for maior que a tens&atilde;o de a&ccedil;&atilde;o do GDT, o espa&ccedil;o interno da GDT ser&aacute; quebrado. O tubo de descarga de g&aacute;s cer&acirc;mico &eacute; quase curto, circuito neste momento e limita a sobretens&atilde;o a quase 0 volts dentro de 50ns, de modo que a corrente de sobretens&atilde;o pode ser levada &agrave; terra rapidamente e, em seguida, o equipamento pode ser protegido de forma segura. Quando a sobre tens&atilde;o desaparecer, o tubo de descarga de g&aacute;s cer&acirc;mico ir&aacute; apagar e retornar ao estado de isolamento alto, preparando-se para a pr&oacute;xima a&ccedil;&atilde;o.<br /><br /><a href="http://www.kingtronics.com/surge-arresters/" target="_blank"><img src="https://www.m7diode.com/upload/Kingtronics-Gas-Discharge-Tube-Kt.jpg" alt="" title="" style="line-height: 19.2000007629395px;" /></a></p>]]></description><category>Surge Arresters</category><comments>https://www.m7diode.com/post/767.html#comment</comments><wfw:comment>https://www.m7diode.com/</wfw:comment><wfw:commentRss>https://www.m7diode.com/feed.asp?cmt=767</wfw:commentRss><trackback:ping>https://www.m7diode.com/cmd.asp?act=tb&amp;id=767&amp;key=465be5f5</trackback:ping></item><item><title>Kt SKT-3R-SMD5076 Gas Discharge Tube</title><author>a@b.com (admin)</author><link>https://www.m7diode.com/post/757.html</link><pubDate>Mon, 22 Jan 2018 10:11:01 +0800</pubDate><guid>https://www.m7diode.com/post/757.html</guid><description><![CDATA[<p><span style="line-height: 19.2000007629395px;">Kingtronics vende dois p&aacute;ra-raios de eletrodos e p&aacute;ra-raios de 3 eletrodos.</span><br style="line-height: 19.2000007629395px;" /><span style="line-height: 19.2000007629395px;">Incluindo 2 Arrasadores de Sobretens&atilde;o 8 * 6mm, 2 Arrasadores de Sobretens&atilde;o SMD4532.2 Dispositivos de Suspens&atilde;o de Sobretens&atilde;o SMD5042.3 Dispositivos de Sobretens&atilde;o 8 * 10mm, 3 Dispositivos de Sobretens&atilde;o SMD5076</span><br style="line-height: 19.2000007629395px;" /><br style="line-height: 19.2000007629395px;" /><span style="line-height: 19.2000007629395px;">Hoje, recomendamos o nosso tubo de descarga de g&aacute;s SMT SKT-3R-SMD5076 para voc&ecirc;</span><br style="line-height: 19.2000007629395px;" /><br style="line-height: 19.2000007629395px;" /><span style="line-height: 19.2000007629395px;
