Abstract
The invention discloses a transformer substation insulator creepage distance online measuring device which is composed of a linear laser emitter, an image sensor, a connecting rod, a supporting rod, a support and a tilt motor. The linear laser emitter and the image sensor are fixed to the two ends of the connecting rod through fixing blocks. The connecting rod and the supporting rod are connected and fixed. By controlling the tilt motor, the tilt range of the linear laser emitter and the tilt range of the image sensor are controlled, and then influences on the outer contour of a whole insulator are obtained. Through the non-contact method, the creepage distance of the insulator can be rapidly, accurately and safely measured, and sufficient data support is provided for pollution flashover prevention work.
Description
Technical field
The present invention relates to a kind of Substation Insulator creepage distance on-line measurement device, belong to electric system transmission facility technical field.
Background technology
Along with economic fast development, highly energy-consuming, polluted enterprises progressively increase, and atmospheric pollution increases the weight of year by year, and floating dust and haze weather emerge in an endless stream, and these factors have all increased the weight of the filth of insulator surface and assembled.Once pollution flashover accident occurs, and will directly cause electric grid large area power cut, even causes network system to disintegrate, and is having a strong impact on the safe operation of electric system, and is bringing heavy losses to national economy.Therefore, regularly carrying out insulate filthy degree and external insulation parameter measurement of power transmission and transforming equipment is one of main contents of the anti-pollution flashover work of electric system.
, mainly there is crack, surface fracture etc. to insulator inside concentrating on, and to on-line measurement insulator creepage distance, there is no correlative study in the research to insulator on-line monitoring both at home and abroad.
Summary of the invention
The object of the present invention is to provide a kind of Substation Insulator creepage distance on-line measurement device of cordless.
For achieving the above object, the technical solution adopted in the present invention is:
Substation Insulator creepage distance on-line measurement device, by line laser transmitter, imageing sensor, connecting link, support bar, support and upset motor form, a fixed block of the each installation in two ends of described connecting link; The bottom hookup wire generating laser of a described fixed block, the bottom installation diagram image-position sensor of another fixed block; The center of described support bar and connecting link is connected and fixed; Described support bar connects upset motor; Described upset motor is fixed on support.
Aforesaid line laser transmitter is the green line generating laser of 532nm.
Aforesaid fixed block and connecting link adopt the mode being threaded to be connected and fixed.
Aforesaid line laser transmitter and fixed block, imageing sensor and fixed block are adopted and are screwed.

Brief description of the drawings
Fig. 1 is Substation Insulator creepage distance on-line measurement apparatus structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, Substation Insulator creepage distance on-line measurement device of the present invention, by line laser transmitter 3, imageing sensor 7, connecting link 1, support bar 6, support 5 and upset motor 4 form, wherein,
The two ends of connecting link 1 are provided with screw thread, and a side of each fixed block 2 is provided with threaded hole, and the threaded hole of the screw thread of connecting link 1 and fixed block 2 matches, and makes fixed block 2 be fixed on the two ends of connecting link 1.
The bottom hookup wire generating laser 3 of a fixed block, the bottom installation diagram image-position sensor 7 of another fixed block; Line laser transmitter and fixed block, imageing sensor and fixed block are all adopted and are screwed.
Connecting link 1 is solid steel, is provided with threaded hole in the center of connecting link 1, and the end of support bar 6 is provided with screw thread, and the screw thread of the threaded hole of connecting link 1 and support bar 6 matches, and support bar 6 and the center of connecting link 1 are fixed.
Support bar 6 connects upset motors 4, by the controls motor 4 that overturns, can make support bar 6 overturn arbitrarily angled, thereby drive connecting link 1 overturns, and realizes the upset of line laser transmitter 3 and imageing sensor 7.
Upset motor 4 is fixed on A-frame 5, is convenient to place.
Preferably, line laser transmitter 3 of the present invention adopts the green line generating laser of 532nm.
Principle of work of the present invention is: first use line laser transmitter Emission Lasers bar, formation insulator outline feature crossing with insulator surface, then imageing sensor obtains the insulator image that comprises laser strip, measures the creepage distance of insulator by the laser strip on insulator image; For fear of blocking between insulator umbrella, need to absorb the insulator image of multi-angle, by upset motor, change the emission angle of line laser transmitter and the camera angle of imageing sensor, thereby the insulator image that obtains multi-angle as much as possible, finally obtains the image of whole insulator outline.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
