Abstract
The invention discloses a high-intensity arc voltage gas electrical discharge tube, which comprises electrodes and a hollow ceramic tube, wherein the electrodes and the hollow ceramic tube are welded to form a sealed cavity, and a mixture of nitrogen gas and hydrogen gas is mainly filled in the cavity, wherein the nitrogen gas accounts for less than 90 percent of the total volume, and a gap between the two electrodes of the gas electrical discharge tube is larger than 0.5mm. After the technical scheme is adopted, the arc voltage of the gas electrical discharge tube can be improved to 26V or higher than 26V. When the gas electrical discharge tube is applied to fields such as power supplies and the like, the effect of no follow current can be realized without the combination of a plurality of gas electrical discharge tubes, and the invention brings convenience for users.
Description
Technical field
The present invention relates to a kind of gas discharge tube.In particular, the present invention relates to a kind of kind and content (volume ratio of respectively forming gas), thereby can make the discharge tube arc voltage be increased to 26V or above gas discharge tube by the gas in the change discharge tube.
Background technology
On electronic system and network line, be subjected to extraneous instantaneous overvoltage through regular meeting and disturb, these interference sources mainly comprise: since break-make inductive load or start and stop high power load, the switching overvoltage that line fault etc. produce; Because the lightning surge that natural phenomenas such as thunder and lightning cause.This overvoltage (or overcurrent) is called surge voltage (or surge current), is that a kind of transition is disturbed.The trouble free service of surge voltage meeting serious harm electronic system.The elimination surge noise disturbs, and prevents that surge harm from being the key problem of connection-related electricity use subset safe and reliable operation always.For fear of surge voltage infringement electronic equipment, the general shunting defensive measure that adopts, be about to surge voltage in the very short time with the earth short circuit, make surge current branch inflow place.
Surge arrester can be connected with the earth by the electric energy in the absorption transient process or with it avoids equipment to be damaged.Surge arrester can recover automatically, can handle the repetition transition, can't lose efficacy.Wherein gas discharge tube relatively is commonly used in above-mentioned every field, and a key property of gas discharge tube is the speed and the selective power of igniting, and in other words, gas discharge tube must effectively move and not time-delay, and it triggers with the signal of communication of standard.But present technology, when needing gas discharge tube to be applied in the occasion of arc voltage about 26V, single gas discharge tube can not be realized, necessary series connection by a plurality of gas discharge tubes, or the combination of gas discharge tube and other device, brings constant to use.Also new requirement has been proposed to industry.
Summary of the invention
At the deficiency that existing gas discharge tube is used, the inventor is through concentrating on studies, and the inventor realizes the production of the gas discharge tube of the high arc voltage of tool by changing the volume ratio of each gas in the discharge tube.
The technical solution used in the present invention is:
A kind of gas discharge tube of high arc voltage, comprise electrode and hollow ceramic pipe, by an electrode and an airtight cavity of hollow ceramic pipe welding formation, blanketing gas in the cavity, it is characterized in that: mainly fill out the mixture of nitrogen and hydrogen in the cavity of discharge tube, wherein nitrogen accounts for below 90% of cumulative volume.
Wherein hydrogen filling ratio is 30% of a volume of mixture, and nitrogen filling ratio accounts for 70% of volume of mixture.
Can both guarantee that the arc voltage of discharge tube is more than 26V through a large amount of two gaps between electrodes that experiment showed, gas discharge tube after greater than 0.5mm.
The form of discharge tube can be the two poles of the earth discharge tube or three the two poles of the earth discharge tubes.
After the present invention has adopted above-mentioned technical scheme, the arc voltage of gas discharge tube can be increased to 26V or more than, in the application that a plurality of need are selected the above field of 26V for use, do not need just can realize by the combination of gas discharge tube, bring convenience to the user.

Embodiment one
A kind of two utmost point gas discharge tubes as Fig. 1 comprise two metal electrodes 1, metallized ceramic pipe 6.Emitting stage 2 is set on the metal electrode, it is integrally welded and form an airtight cavity 5 with two metal electrodes 11 and metallized ceramic pipe 6 by 4 welding of yellow gold solder by the metal electrode 1 of 2 ends, metallized ceramic pipe 6 back to be installed, gap between two metal electrodes 1 is set to 1.0mm, fill the mixture of nitrogen and hydrogen in the cavity 5, wherein hydrogen filling ratio accounts for 50% of cavity volume, and nitrogen accounts for 50% of cavity volume.
Embodiment two
As a kind of three utmost point gas discharge tubes of Fig. 2, comprise two termination electrodes 1, target 3 and hollow metal earthenware 6, two termination electrodes 1, target 3 and hollow metal earthenware 6 integrally welded backs are formed an airtight cavity 5, fill the mixture of nitrogen and hydrogen in the cavity 5, wherein hydrogen filling ratio account for 30%, the packing volume of nitrogen is 70%; The target of gas discharge tube and the gap between the two end electrodes are for being arranged to 1.2mm.
Identify through experimental result, the gas discharge tube that the technical scheme of two above-mentioned embodiment is made, arc voltage all can guarantee 26V or more than.When discharge tube of the present invention uses, effectively improved the problem of discharge tube afterflow.
