倍加福安全栅齐纳安全栅是在电路中采用熔断器、限流电阻或限压二极管以对输入的电能量进行限制，保障输出到危险区的能量的安全仪表。该仪表在安装时需要注意：要有接地系统，并且齐纳式安全栅的接地电阻要小于1欧姆，否则便失去防爆安全保护性能。 来自危险区的现场仪表必须是隔离型，否则通过齐纳式安全栅的接地端子与大地相接后信号无法正确传送，并且由于信号接地，直接降低信号抗干扰能力，影响系统稳定性。 倍加福安全齐纳式安全栅对电源影响较大，同时也易因电源的波动而造成齐纳式安全栅的损坏，因此使用齐纳式安全栅的场所对电源的稳定性要求较高。由于齐纳式安全栅的电路原理需要吸收输入回路的能量，所以易造成输出不稳定，在使用和安装时需要注意。http://www.amypf.com/027-87263542手机：18372021864LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&pra=5&wgl=1&dt=1650941080214&bpp=12&bdt=248&idt=130&shv=r20220420&mjsv=m202204190101&ptt=9&saldr=aa&cookie=ID%3D2c186cce80d69fb1-221c8408a0ce006c%3AT%3D1636508022%3ART%3D1636508022%3AS%3DALNI_Mbu0HZjDtEO7dny0NgdC9Kvxw3uwg&nras=1&correlator=235040270399&frm=23&ife=1&pv=1&ga_vid=944967440.1650941080&ga_sid=1650941080&ga_hid=1442037961&ga_fc=0&nhd=1&u_tz=480&u_his=10&u_h=1080&u_w=1920&u_ah=1042&u_aw=1920&u_cd=24&u_sd=1&DMC=4&adx=-12245933&ady=-12245933&biw=1030&bih=905&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44759875%2C44759926%2C44759837%2C44761043%2C31067067%2C31061828&oid=2&pvsid=4315365250728937&pem=217&tmod=915187227&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=781%2C2%2C781%2C2%2C1920%2C0%2C1078%2C1042%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&alvm=r20220421&fu=32772&bc=31&ifi=1&uci=1.y3wunkjgrtsy&fsb=1&dtd=151" data-google-container-id="1.y3wunkjgrtsy" data-load-complete="true"> |
