Description
Technical field
The present invention relates to gas discharge tube, espespecially a kind of be designed with low temperature gas storage, high temperature discharge gas, reusable gas blast arc-quenching without afterflow ceramet gas discharge tube, be suitable for most power lightning protection module, also can be used for the lightning-protection overvoltage module of other electric equipment.
Background technology
As everyone knows, ceramet gas discharge tube is as a switch element that only depends on voltage, rely on its superpower overcurrent capability, extremely short response time and minimum interelectrode capacitance, be widely used in electronic equipment signal, power-supply system, to protect thunderbolt and the overvoltage brought of electromagnetic pulse to infringement that electronic equipment was caused.
What use at present is series gap scheme without afterflow ceramet gas discharge tube lightning protection module of power source, as the multi-clearance ceramet gas discharge tube with external trigger terminal (CN101317178B), the improved multi-clearance ceramet gas discharge tube with external trigger terminal (CN201438604U) of Chinese patent bulletin, they are at present safely, stablize the technology of feasible online use.Because its cost price is high, for security context, require very high industry, its cost performance can be accepted; But requiring for security context is not that very high its price of low-end market is difficult to bear, be unfavorable for promoting in these occasions.Therefore, be necessary to design a kind of low-cost without afterflow ceramet gas discharge tube, with solving the needs of high and low end market power lightning protection.
Summary of the invention
The technical issues that need to address of the present invention are that its price of low-end market too high without afterflow ceramet gas discharge tube production cost, that require not to be very high at security context due to above-mentioned prior art is difficult to bear, is unfavorable for requiring the low-end market that is not very high to promote at security context, provide a kind of without afterflow gas discharge tube, it can guarantee the good result of power lightning protection, can reduce production costs again, can meet the inexpensive requirement in high and low end power lightning protection market completely.
For achieving the above object, the present invention adopts following technical scheme without afterflow gas discharge tube:
Without afterflow gas discharge tube, comprise termination electrode and metallized ceramic pipe, described in two, termination electrode is welded respectively and is equipped with the two ends of metallized ceramic pipe by air-tightness, and in metallized ceramic pipe, forms airtight discharging gap, in this discharging gap, fills with inert gas, in this discharging gap, also fill to have the gas of the energy extinguish arcs that can be discharged by low-temperature storage, high temperature, the position also contacting with discharging gap at termination electrode is equipped with can produce the extinguish arcs device that air-flow extinguishes the electrical discharge arc in discharging gap, or, the position that the position contacting with discharging gap at termination electrode and metallized ceramic pipe contact with discharging gap is all equipped with and can produces the extinguish arcs device that air-flow extinguishes the electrical discharge arc in discharging gap, described extinguish arcs device is under low temperature, only to adsorb the gas of the described energy extinguish arcs of filling in discharging gap to store, under high temperature, the gas of the described energy extinguish arcs of absorption is discharged to form made plates or blocks or the ring bodies of material of air-flow to discharging gap.
The gas of described energy extinguish arcs is hydrogen.
The plates that described extinguish arcs device is titanium sponge or blocks or ring bodies.
Described termination electrode has an end protruding out in metallized ceramic pipe.
The position that described termination electrode contacts with discharging gap is the installing hole of the system that open center of the described end at termination electrode.
The position that described metallized ceramic pipe contacts with discharging gap is the position of the discharging gap contact between the described end of termination electrode described in described metallized ceramic Guan Shangyu two.
Described air-tightness welding at high temperature realizes by silver-copper brazing alloy.
Working mechanism of the present invention is: the material (as titanium sponge etc.) that forms extinguish arcs device has the key property of selective absorption, under low-temperature condition (below 200 ℃), adsorption capacity to the gas (as hydrogen) of energy extinguish arcs is very strong, and inert gas is adsorbed hardly; Under the condition of high temperature (more than 200 ℃), the gas (as hydrogen) of adsorbed energy extinguish arcs can be discharged rapidly.When the overvoltage such as be not struck by lightning attacks, in metallized ceramic pipe, can not discharge, in pipe, temperature is in described low-temperature condition, and the gas (as hydrogen) that is filled in the energy extinguish arcs in pipe is adsorbed in it by extinguish arcs device (as titanium sponge).When the overvoltage such as be struck by lightning attacks, in metallized ceramic pipe, produce rapidly arc discharge, the high temperature of arc discharge discharges rapidly the gas (as hydrogen) of a large amount of energy extinguish arcs of extinguish arcs device (as titanium sponge) absorption, in pipe, form the air-flow of powerful unionized extinguish arcs gas, electrical discharge arc in discharging gap is extinguished rapidly, thereby stop power-supply system to continue to provide discharging current, make supply unit etc. avoid the short circuit that exists afterflow to cause in discharge tube after the overvoltage such as thunder and lightning, even fire.
Beneficial effect of the present invention is:
One arranges extinguish arcs device in metallized ceramic pipe, and it is effective that thunderbolt energy is released.When the overvoltage such as be struck by lightning attacks, in metallized ceramic pipe, produce rapidly arc discharge, utilize high arc temperature, the gas (as hydrogen) of a large amount of energy extinguish arcs of extinguish arcs device (as titanium sponge) absorption discharges rapidly, in pipe, form the air-flow of powerful unionized extinguish arcs gas, electrical discharge arc in discharging gap is extinguished rapidly, make supply unit etc. avoid the short circuit that exists afterflow to cause in discharge tube after lightning overvoltage, fire even, can meet in any environment the needs of power-supply device to Lightning Over-voltage protection completely.
Its two, the present invention is simple in structure, than the series gap formula of current use, without the structure of afterflow ceramet gas discharge tube lightning protection module of power source, to simplify many, thereby low cost of manufacture.
Its three, the present invention has the advantage of effective and low cost of manufacture of the electric discharge afterflow that fractures concurrently, is convenient to popularization.
