Components for low-voltage surge protective devices - Part 311: Performance requirements and test circuits for gas discharge tubes (GDT)

EN 61643-311-2013 发布历史

This part of IEC 61643 is applicable to gas discharge tubes (GDT) used for overvoltage protection in telecommunications@ signalling and low-voltage power distribution networks with nominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c..They are defined as a gap@ or several gaps with two or three metal electrodes hermetically sealed so that gas mixture and pressure are under control. They are designed to protect apparatus or personnel@ or both@ from high transient voltages. This standard contains a series of test criteria@ test methods and test circuits for determining the electrical characteristics of GDTs having two or three electrodes. This standard does not specify requirements applicable to complete surge protective devices@ nor does it specify total requirements for GDTs employed within electronic devices@ where precise coordination between GDT performance and surge protective device withstand capability is highly critical. This part of IEC 61643 -does not deal with mountings and their effect on GDT characteristics. Characteristics given apply solely to GDTs mounted in the ways described for the tests; -does not deal with mechanical dimensions; -does not deal with quality assurance requirements; -may not be sufficient for GDTs used on high-frequency (>30 MHz); -does not deal with electrostatic voltages; -does not deal with hybrid overvoltage protection components or composite GDT devices.
