Title:
OVERVOLTAGE PROTECTION APPARATUS, AND GAS DISCHARGE TUBE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/040222
Kind Code:
A1
Abstract:
The present application relates to the technical field of overvoltage protection devices, and provides an overvoltage protection apparatus, and an active fault removal type gas discharge tube and a preparation method therefor. The gas discharge tube comprises a first insulating tube body, two electrodes, and two connecting members. The two electrodes are respectively disposed at either end of the first insulating tube body, and define a discharge cavity together with the first insulating tube body, and the surfaces of the two electrodes facing the discharge cavity form discharge surfaces; each connecting member is sandwiched between the corresponding electrode and the first insulating tube body, and is used for sealingly connecting the corresponding electrode to the first insulating tube body, the two connecting members are each provided with a high-temperature connecting portion, and at least one of the two connecting members is further provided with a low-temperature connecting portion; the low-temperature connecting portion and the high-temperature connecting portion are connected end to end to form a ring, and the melting point of the low-temperature connecting portion is lower than that of the high-temperature connecting portion. The gas discharge tube provided by the present application has high ability to interrupt power frequency follow current, and the electrodes will not be disconnected from the first insulating tube body, so that the overall safety of the gas discharge tube is high.
