Problems solved by technology

But at the same time, if the overvoltage lasts for a long time or occurs frequently, or if there is a long-term or high-current power-frequency overcurrent, the gas discharge tube will heat up due to the long-term or frequent overcurrent, which is too high. The temperature will not only affect the safe use of other devices in the circuit, but also make the gas discharge tube have a risk of short circuit or burst, and even burn the customer's circuit board to cause a fire

Embodiment Construction

[0032] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings. It should be explained in advance that the high-temperature solder referred to in the present invention refers to the solder whose melting point is greater than 500°C, and the high temperature refers to a temperature greater than 500°C; the low temperature referred to in the present invention is a lower temperature than the high temperature, which is 500°C and a temperature below 500°C; the low-temperature sealing adhesive referred to in the present invention refers to a sealing material that can withstand low temperatures, and the material will melt, deform or even liquefy in an environment higher than the above-mentioned low temperature, resulting in failure to seal; The insulating tube body is a glass tube, a porcelain tube or other insulating tubes suitable for the material of the gas discharge tube; the gas discharge tub...

Abstract

The invention provides a gas discharge tube. The gas discharge tube comprises at least two electrodes and an insulation tube body in sealing connection with the electrodes to form a discharge inner cavity. The gas discharge tube is provided with a low-temperature sealing binding agent for sealing the discharge inner cavity, and the low-temperature sealing binding agent is melted at a specific low temperature to enable the discharge inner cavity to generate leakage. According to the invention, the gas discharge tube, in case of a lightning stroke or surge overvoltages, can have a function of discharging lightning currents or the overvoltages; and when the low-temperature sealing binding agent is melted due to a temperature rise caused by heating in case of certain continuous power frequency currents or overlarge power frequency currents, the gas discharge tube generates the leakage to cause an open circuit, and thus subsequent currents are rapidly cut off.

Description

technical field [0001] The invention relates to the field of overvoltage protection products, in particular to a gas discharge tube. Background technique [0002] The gas discharge tube is a switch type protection device, usually used as an overvoltage protection device. The gas discharge tube commonly used at present is made of an insulating tube body and electrodes sealed at both ends, and the inner cavity is filled with inert gas. When the voltage across the electrodes of the gas discharge tube exceeds the breakdown voltage of the gas, a gap discharge will be caused, and the gas discharge tube will quickly change from a high-resistance state to a low-resistance state, forming a conduction, thereby protecting other devices connected in parallel with it. . But at the same time, if the overvoltage lasts for a long time or occurs frequently, or if there is a long-term or high-current power-frequency overcurrent, the gas discharge tube will heat up due to the long-term or fr...
