Utility model content
For the problem in background technology, the utility model proposes a kind of travelling wave tube with electric spark detection apparatus, comprise travelling wave tube, its improvement is: on the tube wall of described travelling wave tube, be provided with a plurality of through holes, in each through hole, be plugged with a fibre-optical probe, the output of a plurality of fibre-optical probes is all connected with a processing unit; The power control part of travelling wave tube and processing unit electrical connection; The device that described a plurality of fibre-optical probe and processing unit form is electric spark detection apparatus.
The operation principle of aforementioned means is: electric spark phenomenon can be attended by electric spark and occur, based on existing optical detection technique, inventor adopts fibre-optical probe to gather the light signal that electric spark sends, light signal is after opto-electronic conversion, processing unit can be by the processing of the signal of telecommunication being identified to whether occur electric spark phenomenon in travelling wave tube, once electric spark phenomenon occurs, just by processing unit by electrical means by the power remove of travelling wave tube, solve personal monitoring in prior art and had the problem of monitoring blind area, also solved the lower problem of manual power cutoff efficiency simultaneously, thereby effectively reduce the probability that travelling wave tube burns out, travelling wave tube is played to effective protection.The photoelectric detecting technology of this electric spark detection apparatus based on existing maturation, simple in structure, with low cost.
In order to improve the collecting efficiency of fibre-optical probe to light signal, the utility model has also proposed following preferred version for fibre-optical probe: described fibre-optical probe is comprised of housing and fiber bundle, and described fiber bundle is comprised of many sensor fibres; Described housing is plugged in through hole, and fiber bundle passes in housing, and the outer end of fiber bundle is exposed outside housing and be positioned at tube wall inner side.Wherein, housing has played two effects, and one, tightens into a bundle by fiber bundle, avoids optical fiber at random, its two, for fiber bundle is fixed on to tube wall; Sensor fibre has also played two effects, one, the exposed part of sensor fibre outer end plays the effect of perception external optical signal, they are two years old, the other end of sensor fibre arrives photoelectric sensor by the optical signal transmission collecting, many sensor fibres can effectively increase the search coverage of fibre-optical probe, improve the sensitivity of fibre-optical probe.
In order to expand the transmission mode of sensor fibre, preferably, described sensor fibre is multimode fiber.
In order further to increase the search coverage of fibre-optical probe, the utility model has also been done following improvement: the outer face of the many sensor fibres formation sphere that is stitched together.Specifically add man-hour, can the outer face integral body of many sensor fibres be polished into sphere by existing optical fiber lapping technique.
Preferably, described processing unit is comprised of a plurality of photodetectors and a processing module, and the input of photodetector is connected one by one with fibre-optical probe, and the output of photodetector is connected with processing module, and processing module is connected with the power control part of travelling wave tube; Described photodetector is converted into the signal of telecommunication for the light signal that fibre-optical probe is collected; Described processing module judges in travelling wave tube, whether to occur electric spark phenomenon according to the output signal of photodetector, if there is electric spark phenomenon, processing module is passed through the power control part of travelling wave tube by the power remove of travelling wave tube, postpone after certain hour, processing module is controlled again the power control part of travelling wave tube by the power connection of travelling wave tube.
Between the general 200nm ~ 550nm of wave-length coverage due to electric spark, preferably, described photodetector adopts green glow detector.
Useful technique effect of the present utility model is: can detect uninterruptedly electric spark phenomenon, after electric spark phenomenon occurs, can efficiently travelling wave tube be turn-offed in time, reduce the probability that travelling wave tube burns out, travelling wave tube is played to effective protection.
