Abstract
The utility model relates to a high-energy ignition discharge tube with a ceramic metal structure, which aims to provide a high-energy high-frequency double-electrode air discharge tube suitable for a high-energy ignition system, solve the problems of weak intensity and bad environmental suitability of the existing high-energy ignition discharge tube and also reduce pollution to the environment. The high-energy ignition discharge tube comprises a ceramic shell (1), an anode discharge assembly and a cathode discharge assembly. Each set of discharge assemblies comprises an electrode (3A or 3B) and an outer edge cover (2A or 2B). The electrode of each set of discharge assemblies is connected with the corresponding outer edge cover. The outer edge cover and the ceramic shell are in braze welding seal. The utility model is characterized in that the electrodes of the discharge assemblies are provided with circular graphite conductive bands (4A, 4B). The outer edges of the circular graphite conductive bands (4A, 4B) are matched with the inner surface of the ceramic shell (1) and the inner holes of the circular graphite conductive bands (4A, 4B) are matched with the outer surfaces of the electrodes (3A, 3B) to make the electrodes inserted in the inner holes.
Description
Technical field
The utility model relates to a kind of discharge tube for guiding target or material discharging, refers to a kind of ceramet structure high-energy ignition discharge tube especially.
Background technology
High-energy ignition discharge tube includes ceramic package, positive discharge assembly and negative discharge assembly, and each group discharge assembly comprises electrode and outer rim cover, and the electrode of every group of discharge assembly is connected outer rim cover and ceramic package sealed with brazing with corresponding outer rim cover.At present, extensively adopt the bipolar electrode vacuum discharge tube in the high-energy ignition system, be controlled at the igniting executive component with it---pulsed discharge on the spark plug.When lighting heavy oil, residual oil oil gun, not only need bigger impulse discharge energy, but also the discharge frequency of having relatively high expectations.And the bipolar electrode vacuum discharge tube, because the restriction of its structure can not be satisfied the requirement of high energy, high frequency simultaneously, if strengthen the impulse discharge energy, discharge frequency is with regard to corresponding reduction, if increase discharge frequency, thereby then discharge tube does not stop arc and loses the control action of paired pulses discharge.Simultaneously big, the weak strength of existing high-energy ignition discharge tube volume, environmental suitability is poor, the switch number of times is few, the voltage drift big, production process uses international restriction to use material, contaminated environment.
Summary of the invention
The purpose of this utility model is to provide a kind of ceramet structure high-energy ignition discharge tube: can reach high energy, high frequency requirement simultaneously, be applicable to the bipolar electrode air discharge tube of high-energy ignition system, the shortcoming of the weak strength of the existing high-energy ignition discharge tube of solution, the deficiency of environmental suitability difference reduces the pollution to environment simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ceramet structure high-energy ignition discharge tube, compare with existing bipolar electrode vacuum discharge tube, identical is to have two electrodes of yin, yang and earthenware or glass envelope, and different is to have increased by two circular graphite bands.Thereby the utility model includes ceramic package, positive discharge assembly and negative discharge assembly, each group discharge assembly comprises electrode and outer rim cover, the electrode of every group of discharge assembly is connected with corresponding outer rim cover, and outer rim cover and ceramic package sealed with brazing is characterized in that; On the electrode of each group discharge assembly a circular graphite band is arranged all, the outer rim of this circular graphite band and ceramic package inner surface match, and the endoporus and the electrode of this circular graphite band match, and electrode is embedded in its endoporus.
The beneficial effects of the utility model are: introduce extraordinary graphite band and solve the international restriction of traditional handicraft use materials used, reduce the pollution to environment, make this discharge tube that broad more application be arranged.The very change of the objective electric field of existing discharge, spread of voltage and environmental issue have been solved.Have simultaneously that volume is little, strength of discharge is high, environmental suitability is strong, the life-span is long and the voltage drift is little.

Fig. 2 is the performance test data table of an embodiment of the utility model.
Among Fig. 1: 1 is that ceramic package, 2A, 2B are that outer rim cover, 3A, 3B are that electrode, 4A, 4B are graphite band, the 5 soldering positions for ceramic package and outer rim cover.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing, the utility model includes ceramic package 1, positive discharge assembly and negative discharge assembly, each group discharge assembly comprises electrode (3A or 3B) and outer rim cover (2A or 2B), the electrode of every group of discharge assembly is connected with corresponding outer rim cover, outer rim cover and ceramic package sealed with brazing, it is characterized in that: on the electrode of each group discharge assembly a circular graphite band 4A is arranged all, 4B, circular graphite band 4A, the outer rim of 4B and ceramic package 1 inner surface match, the endoporus of circular graphite band and electrode 3A, the outer surface of 3B matches, and electrode is embedded in its endoporus.
It is that TYPE, specification are the relevant technologies data test data of a kind of ceramet structure high-energy ignition discharge tube of KGW3.0 that Fig. 2 has provided embodiment model of the utility model.
