The plurality of optical fiber probes are in one-to-one connection with the plurality of photoelectric detectors. The plurality of photoelectric detectors are all connected with the processing module. The beneficial effects of the utility model comprise: the device which can detect the electric sparking phenomenon is provided; the defect that there is a dead zone in manual monitoring is ironed out; the technology that the device is based on is mature and complete; the structure of the device is very simple; and the cost is low.
Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of electric spark detection apparatus.
Background technology
In many electronic equipments, all there is electric spark phenomenon, for the higher equipment of some precision, the harm of electric spark phenomenon is very large, if processed not in time, likely cause device damage, if only depend on human eye to monitor electric spark phenomenon, not only require great effort, and have a large amount of blind areas, therefore, being necessary to design a kind of special checkout equipment detects electric spark phenomenon.
Utility model content
For the problem in background technology, the utility model proposes a kind of electric spark detection apparatus, its structure is: described electric spark detection apparatus is comprised of a plurality of fibre-optical probes, a plurality of photodetector and processing module; A plurality of fibre-optical probes are connected one by one with a plurality of photodetectors, and a plurality of photodetectors are all connected with processing module.
The principle of aforementioned means is: electric spark phenomenon can be attended by electric spark and produce, if collect the light signal that electric spark sends, just can confirm to have occurred electric spark phenomenon, therefore, the utility model utilizes ripe optical detection technique, light signal in monitored area is detected, thereby allow people know in time whether electric spark phenomenon occurs, to take corresponding counter-measure.
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 fibre bundle, and described fibre bundle is comprised of many sensor fibres; Fibre bundle passes in housing, and the outer end of fibre bundle is exposed outside housing.Wherein, housing has played two effects, and one, tightens into a bundle by fibre bundle, avoids optical fiber at random, its two, for fibre bundle being fixed near monitored area; 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.Housing can adopt ceramic material.
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.
In order to expand the transmission mode of sensor fibre, preferably, described sensor fibre is multimode optical fiber.
Between the general 200nm ~ 550nm of wavelength coverage due to electric spark, preferably, described photodetector adopts green glow detector.
Described electric spark detection apparatus can be only used as monitoring, alarming, also can be by after itself and the electrical connection of monitored device, by it, according to electricity sparking situation, make quick disposal, such as: when electric spark detection apparatus of the present utility model is used for the internal electrical spark phenomenon of travelling-wave tube to monitor, can on the tube wall of travelling-wave tube, through hole be set, fibre-optical probe is plugged in through hole, the power control part of processing module and travelling-wave tube is coupled together simultaneously, when travelling-wave tube is inner, occur after electric spark phenomenon, by simple control program, realize processing module automatically shutting down TWT Power, thereby effectively protect travelling-wave tube, avoid travelling-wave tube to burn out.
Useful technique effect of the present utility model is: a kind of device that can monitor electric spark phenomenon is provided, has avoided personal monitoring to have the defect of blind area; The technology maturation that this device relies on, perfect, the structure of device itself is very simple, with low cost.
