Background technology transmission line of electricity will generate heat in transmission of electricity process, and particularly at the aerial device heating point of transformer station, need to be grasped its temperature, current methods uses infrared detection equipment.The precision of infrared detection and check point are apart from the distance dependent between tested measuring point.There is comparability for making to detect data for each time, correctly to judge its temperature variation, needing fixed point orientation to detect tested measuring point.It is consistent that the existing fixed point orientation method remembering erect-position by people can not ensure to detect erect-position each time.Need a kind of technology of the directed erect-position that ensures to fix a point.
Summary of the invention infrared detection locating pad, is fixed on selected check point, and each measuring station thereon, can ensure that each detection has identical erect-position, realizes fixed point oriented detection.Infrared detection locating pad (accompanying drawing) is a hard plastic backing strap.Pad is used color subregion; Use symbol direction and location.Pad is divided into positioning area 2 and Zhan Jiao district 6 by a V word separatrix.In positioning area 2, orienting arrow 1 balanced configuration, in the apical axis line front end of pad, points to place, measured point vertically upper thread.Have the footprint shape pin position 3 of about a pair point in Zhan Jiao district 6, the also pin point 4 of bipod position 3 is on the apical axis line of pad.The profile of bipod position 3 and V word two sideline and top line extended line tangent.Respectively there is a hole for nailing 7 corner of pad, is fixed on ground for hammering into steel nail.There is a limit, circle slope 5 on four limits of pad, make pad can not form Ge rib over the ground, in order to avoid people's pin touches pine pad.There is one deck adhesive sticker at the back side of pad, and has cuticula to protect.Do not allowing the ground sticky pad of nail in ground.
During use, first should select measuring point, then connect a straight line from measuring point to measured point at the vertical projection on ground point, pad apical axis line be overlapped with it, and makes orienting arrow 1 point to the vertical projecting line of measured point.Then at ground fixed bolster: the ground grading not allowing nail in this way, acting as a cushion face cuticula sticky pad can be thrown off in ground; The very not smooth ground allowing again nail nail in this way, available steel nail directly by hole for nailing 7 pad nail on the ground.During measurement, no matter pin size, tiptoe withstands the limit of positioning area 2; Two heels are close to, and also pin point 4 is on the apical axis line of pad.
The advantage of infrared detection locating pad is: 1, fixed point is accurately directed; 2, each erect-position detected is identical, makes each detection have comparability; 3, be convenient to change measuring point; 4, simple and practical.
The contour dimension of embodiment pad: long 400mm; Wide 350mm; Four radius of corner 40mm; Thick 3mm.Limit, slope 5 size: wide 5mm; Namely height pads thick 3mm; The thick 1mm in edge.V word marginal V word limit angle 45 °.Pin position 3 size is No. 38 footwear sole areas and shape, arranges between two parties; And determine the boundary of erect-position district 6 and positioning area 2 accordingly.Four hole for nailing 7 diameter 3mm, centre distance: long 360mm; Wide 310mm.The long 80mm of enclosure rectangle of orienting arrow 1, wide 60mm.Orienting arrow 1 is red, and positioning area 2 is white, and pin position 3 is red, and Zhan Jiao district 6 is green, and limit, slope 5 is red.
