Abstract
The utility model relates to a gas discharge tube having a small diameter and a large through flow. The gas discharge tube includes two discharge electrodes and an insulation tube. The two discharge electrodes are a tube electrode and a column electrode respectively. A part of the column electrode is disposed in an inner cavity of the tube electrode in a suspended manner. Two ends of the insulation tube are packaged with the tube electrode and the column electrode respectively. By adopting the gas discharge tube having the small diameter and the large through flow in the utility model, since a side face distance between the column electrode and the tube electrode is smaller than an end face distance, that an outer side surface of the column electrode discharges to an inner side face of the tube electrode in electrifying is guaranteed, thereby increasing an electrode emission surface. At the same time, since the insulation tube is behind a whole discharge gap, the spurt of electron powder and surface metal material to an inner wall of the insulation tube is reduced effectively. The gas discharge tube having the small diameter and the large through flow in the utility model has a simple structure and can run reliably. The diameter of the gas discharge tube having the small diameter and the large through flow in the utility model is within 10 mm. However, the through-flow capacity reaches to I n =30 kA, I max= 60 kA, 8/ 20 micro S.
Description
Technical field
The utility model relates to gas discharge tube, is the big through-flow gas discharge tube of a kind of minor diameter specifically.
Background technology
Gas discharge tube is widely used in lightning-protection system; Existing diameter adopts the plane symmetry discharging structure shown in the figure one at 10mm with interior compact gas discharge tube usually; The centre is the metallized ceramic pipe; Two ends are the symmetrical metal discharge utmost point, and the electrode emitting surface becomes mesh shape, apply the electronics powder emitting substance that one deck is used for the enhanced discharge ability above.Because the restriction of overall dimensions, the size of its electrode surface of emission is less, and through-current capability is no more than Imax=25KA, and 8/20 μ S, power frequency continued flow breaking capacity be at If=50A, Uc=255V.In addition, electrode surface electronics powder and surface metal material often splatter to the earthenware inwall and the gas discharge tube resistor was lost efficacy.Therefore designing a kind of simple in structure, reliable, diameter, can to reach the big through-flow gas discharge tube of the minor diameter of 60KA at 10mm with interior but Imax very necessary.
Summary of the invention
The purpose of the utility model just provide a kind of simple in structure, reliable, diameter at 10mm with interior but Imax can reach the big through-flow gas discharge tube of the minor diameter of 60KA.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: the big through-flow gas discharge tube of a kind of minor diameter; Comprise two sparking electrodes and an insulated tube; It is characterized in that two sparking electrodes are respectively pipe electrode and post electrode, the part of post electrode is suspended in the inner chamber of pipe electrode, the two ends of insulated tube respectively with pipe electrode and post electrode package.
Further, said insulated tube is an earthenware.
Further, said pipe electrode and post electrode are one-shot forming.
Adopt the utility model; Because the lateral distance between post electrode and the pipe electrode is less than end face distance; So can guarantee when energising, the pipe electrode medial surface to be discharged, thereby increase the electrode surface of emission, simultaneously by post electrode lateral surface; Because of the rear of insulated tube, so effectively reduced electronics powder and surface metal material splatter to the insulated tube inner surface wall at whole discharging gap.The utility model is simple in structure, reliable, diameter at 10mm with interior but can reach In=30KA, Imax=60KA, 8/20 μ S through-current capability.
