The utility model discloses a discharge tube is equipped with the ignite, and during the use, ignite and high -voltage pulse control generator are connected, and when the high -voltage pulse signal was received to the ignite, the ignite was sent high -voltage pulse to and is made on the negative pole boosting at discharge tube both ends so that electric interelectrode gas is punctured, realizes lighting a fire and discharges. The discharge tube of this kind of structure not only discharge voltage scope obtains improving, and discharge frequency is controllable in addition, and a plurality of discharge tubes realize probably that work is synchronous, has improved the reliability of some firearm.
Description
Technical field
The utility model relates to discharge tube technical field, is specifically related to the discharge tube that a kind of discharge frequency is controlled.
Background technology
At present, the basic structure of traditional high-energy ignition gas discharging pipe is a closed body, wherein has two parallel and electrodes of centering, and is filled with a certain amount of working gas.Discharge voltage as required, designs kind and the air pressure of interelectrode Distance geometry working gas according to the numerous stream theory of electronics and Paschen's law.During work, add a high pressure to ignition system, storage capacitor is charged.Because discharge tube is in parallel with storage capacitor, so the voltage at discharge tube two ends also raises, when discharge tube both end voltage exceedes firing voltage, interelectrode gas is breakdown, storage capacitor is discharged to sparking plug by discharge tube, and immediate current is very large, and sparking plug just produces a spark.Then storage capacitor starts the process of charging again, goes round and begins again, realizes the igniting of aero-engine.
Traditional gas discharge tube discharge voltage range is narrow, generally at the positive and negative 100V of nominal value.If voltage fluctuation is large, there will be and leak electric discharge or do not discharge, affect discharge tube normal usage function.In addition, igniter there is multiple discharge tube work simultaneously, need synchronous.Traditional gas discharge tube cannot realize Complete Synchronization.
Utility model content
Narrow for traditional gas discharge tube discharge voltage range, electric discharge can not the deficiency of Complete Synchronization, and the purpose of this utility model is to provide a kind of discharge frequency controllable type discharge tube.
The utility model is achieved through the following technical solutions:
A kind of discharge frequency controllable type discharge tube, comprise the ceramic circular substrate that middle part is provided with through hole, the both sides of ceramic circular substrate are respectively equipped with and are covered in negative electrode end cap on through hole and anode end cap, inner side in the middle part of negative electrode end cap is provided with the negative electrode bending towards through hole, outside is provided with the trigger electrode that through negative electrode end cap abuts to negative electrode, the outside of trigger electrode is enclosed with ceramic cylinder, ceramic cylinder is fixed on cathode terminal and covers, the outside at negative electrode end cap edge is provided with the cathode terminal be communicated with negative electrode, also be provided with the blast pipe identical with cathode terminal cover cavity, inner side in the middle part of anode end cap is provided with the anode bending towards through hole, outside is provided with through anode end cap and the anode terminal be connected with anode.
As preferred embodiment, the shape of described negative electrode end cap and anode end cap is symmetrical with ceramic circular substrate.
The beneficial effects of the utility model are: discharge tube of the present utility model is provided with trigger electrode, during use, trigger electrode is connected with high-voltage pulse control generator, when trigger electrode receives high-voltage pulse signal, high-voltage pulse is delivered on negative electrode and the voltage at discharge tube two ends is raised to make interelectrode gas breakdown by trigger electrode, realizes ignition discharge.The discharge tube of this structure not only discharge voltage range is improved, and discharge frequency is controlled, and it is synchronous that multiple discharge tube may realize work, improves the reliability of igniter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model discharge tube.
Symbol description: 1-ceramic circular substrate, 2-negative electrode end cap, 3-anode end cap, 4-through hole, 5-negative electrode, 6-trigger electrode, 7-ceramic cylinder, 8-cathode terminal, 9-blast pipe, 10-anode, 11-anode terminal.
Embodiment
