Abstract

This metal-ceramic gas discharge tube for unordered current after lightning stroke used for strong current system involves: inner electrode, outer electrode and metallized ceramic insulator. The three are combined to form a space filled with inert gas. In the space there are: discharging gap and one end of inner electrode. It also has central hole coaxial with said inner electrode and several gas-inlet holes connected to siad central hole. The gas inlet hole, central hole and discharging gap are combined to form a circulation loop. This invention solves problems such as: unordered flow in electric source of electronic device, and lightning stroke problem.

Description

Technical field:

[0001] The invention relates to the technical field of discharge tubes, in particular to a cermet gas discharge tube without freewheeling after a lightning overvoltage in a high-voltage power supply system. Background technique:

[0002] It is known that the cermet discharge tube, as a switching element that only depends on voltage, is widely used in electronic equipment signal systems to protect against lightning strikes and The damage caused by the overvoltage caused by electromagnetic pulse to electronic equipment; the application in the current electronic equipment power supply system is limited to equipotential isolation grounding, which is used to solve the problem caused by public grounding in the electronic equipment power supply and signal lightning strike overvoltage protection scheme. crosstalk interference problem.

[0003] According to incomplete statistics, the metal-ceramic gas discharge tubes currently used around the world have a common def...
