Abstract

The invention relates to a novel gas discharge tube. Discharge gaps of the novel gas discharge tube are filled with a dopant, wherein the conduction voltage value of the dopant is higher than that ofa pure inert gas; the discharge gaps are formed by electrodes and an insulating tube body in a sealing connection form, wherein when the voltage applied to the two ends of the electrodes of the novelgas discharge tube reaches the conduction voltage value of the dopant, the dopant is subjected to breakdown; and the novel gas discharge tube begins to discharge to enable the voltage at the two endsof the electrodes not to be higher than the breakdown voltage. By virtue of the novel gas discharge tube, the follow current voltage of the circuit can be increased, the problem of follow current shielding of the gas discharge tube can be solved, and the occupied space of a surge protection circuit also can be reduced.

Description

technical field [0001] The invention relates to the technical field of discharge tubes, in particular to a novel gas discharge tube. Background technique [0002] In the application of communication equipment, such as base station equipment, high-speed rail equipment, etc., inductive surge currents up to several thousand amperes or tens of thousands of amperes pass through. The induced surge current will cause damage to the equipment. During the operation of the communication equipment, it is often necessary to protect the equipment with an anti-surge device (such as a gas discharge tube). [0003] When the traditional gas discharge tube protects the equipment, because the freewheeling voltage is small, it needs to cooperate with other devices to form an anti-surge circuit. Gas discharge tubes are often used in the first or first two stages of a multi-stage anti-surge circuit protection circuit to discharge lightning transient overcurrent and limit overvoltage. However, th...
