Ceramic gas discharge tube in the selection should pay attention to matters!
Ceramic gas discharge tube belongs to the switch components, power supply for lightning arrester common mode circuit, discharge lightning current into, can also be used in the differential mode circuit is connected in series with a varistor and blocking the leakage current. It is often used in the first level discharge surge current in the signal lightning protector. Because of its slow response, the second stage is used as the voltage limiting protection. In this small series today tage electronic technology for the majority of engineers interested in learning to share the GDT in the selection of several elements should pay attention to matters! We should pay attention to in the choice of ceramic gas discharge tube:
(1) directly used in power supply on differential protection ceramic gas discharge tube can not;
(2) the breakdown voltage is greater than the maximum signal voltage;
(3) the current should not be less than the maximum abnormal current on the line;
(4) the pulse breakdown voltage must be less than the voltage of the protected circuit.
In the face of the four points above matters should be kept in mind, in this election which won‘t choose wrong, now for the GDT selection there are questions about friends and consulting other related problems please contact from electronic official website: m.dtgjc.com online manager, or call: 86-755-88365418. address: tage electronic lightning protection, anti-static, overcurrent, Miss voltage technology is always you.. stomping around your protection experts!
