Description
Technical field
The present invention relates to a kind of detection systems, more particularly to a kind of novel ultraviolet arcing detection system of train.
Background technique
Pantograph is in fact made of the Minor contact point of some dispersions with contact net contact area, they subject cunning
Heat caused by dynamic friction and traction current, these heats can make contact point melt to form metal liquid bridge, connect when being connected across electricity
When voltage in touching reaches 2 ~ 3V, a large amount of electronics are escaped from cathode surface occurs sharp impacts most end form with the liquid metal to gasify
At spark；When the voltage being connected across in electrical contact reaches 10 ~ 20V or more, ionisation effect will occur for air gas molecule, occur
Gas discharge forms electric arc.When electric discharge phenomena between contact net and pantograph are serious, the exception between bow net not only will cause
Abrasion can also cause DC traction current disturbing to deteriorate by fluidity energy.
By the arcing detection device of ultraviolet light, the spark that pantograph carbon slide generates during sliding and being in electrical contact is detected
And electric arc, it realizes to arcing non-contact detection, existing detection device mostly uses ultraviolet imager, imager influence factor
It is more, cause precision insufficient, usually judges by accident.
Summary of the invention
The present invention provides a kind of novel train to solve the problems, such as that existing arcing detection system detection accuracy is insufficient
Ultraviolet arcing detection system, the system acquire optical signalling using optical lens, and convert optical signals into electric signal progress
Calculation processing is simultaneously shown.
The technical solution used in the present invention are as follows: a kind of novel ultraviolet arcing detection system of train, including it is placed in roof
On data acquisition device, interior data processing equipment, vehicle-mounted interchanger and display device, the data acquisition device includes using
In the optical lens of acquisition ultraviolet light, the optical lens acquires ultraviolet light and optical signalling is transmitted through the fiber to interior number
According to processing unit, the car data processing equipment connects the display device by vehicle-mounted interchanger, and the display device is
Display device for mounting on vehicle.
Further, the interior data processing equipment is connected with current sensor, described in the current sensor connection
The optical signalling is converted electric signal by data acquisition device, the data acquisition device.
Further, the interior data processing equipment connects train power supply.
Further, the optical lens includes successively from outside to inside protective glass layers, optical filter, for the recessed of optically focused
Mirror is combined with convex lens；The optical filter is used to filter out the light in addition to ultraviolet light；Optical lens group further includes attenuator；Institute
Attenuator is stated between protective glass layers and optical filter.
Further, the roof data acquisition device further includes the camera for acquiring realtime graphic.
Further, the interior data processing equipment includes shaping circuit, filter circuit and analog to digital conversion circuit.
Beneficial effect caused by the present invention include: the ultraviolet arcing detection system of train in the present invention can be realized it is ultraviolet
High precision collecting, transmission and the processing of photoelectricity, so that result is accurate, reliable.
Detailed description of the invention
A kind of structural schematic diagram of the novel ultraviolet arcing detection system of train in Fig. 1 present invention.
Specific embodiment
Further details of explanation is done to the present invention with reference to the accompanying drawings and detailed description, it should be appreciated that
