Description
Technical field
The present invention relates to electric arc technical field of light detection, be specially a kind of cylindrical arclight sensor lens.
Background technology
Power system is once broken down, huge arclight will be produced, producing the biggest light energy radiation and the highest temperature radiation when arclight occurs, these radiation have the biggest destruction to power system, the most also can cause the casualty accident of operator.The extent of injury of arclight depends on the persistent period of arclight, as long as so can quickly limit or cutting system power supply just can lower the infringement that arclight causes effectively.Arclight sensor can detect the intensity of arclight, and then judges whether to need cutting system power supply according to the intensity of arclight.And the sector that arclight sensor the most on the market can only monitor dead ahead about 135 ° conducts the optical signal come; must be by the front of arc photosensor camera lens just to the test point needing detection when of installation; when having multiple test point; it is accomplished by multiple arclight sensor is installed; if Rig up error; easily cause and do not receive the arclight that test point sends, thus do not have the effect of electric arc protection.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of cylindrical arclight sensor lens that a kind of detection angles is bigger, technical scheme is as follows:
A kind of cylindrical arclight sensor lens, including filter part, optical fiber and base, the bottom that described filter part is connected round platform portion by tube one end is constituted, and round platform portion base diameter is more than tube external diameter, and the other end of tube is fixed on described base；The fibre core of described optical fiber is resisted against bottom round platform portion through base and tube；Also including lens, described lens set the cylinder of cavity one end open in being, lens cap is on described filter part, and open at one end is closed with described base and is connected.
Further, the external diameter of described tube is 3.8mm, and internal diameter is 2.5mm, a length of 8.2mm；Described round platform portion base diameter is 5.9mm, and top diameter is 5.5mm, and height is 1.6mm；Described lens external diameter is 12mm, and height is 20mm.
Further, the cavity in described lens be top be the cylinder of cambered surface.
Further, the cavity cylinder basal diameter in described lens is 6.5mm, and height is 11.5mm.
Further, also including connecting portion, described connecting portion is fixedly sleeved on described optical fiber, and connecting portion one end is connected with described base.
The invention has the beneficial effects as follows: the cylindrical arclight sensor lens that the present invention provides can make detection angles increase to 275 ° 300 °, the arc optical signal of multiple test point can be detected simultaneously, thus greatly reduce the difficulty of installation, and greatly reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical arclight sensor lens.
In figure: 1-tube；2-round platform portion；3-base；4-connecting portion；5-optical fiber；6-lens.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings: a kind of cylindrical arclight sensor lens, including filter part, optical fiber 5 and base 3, the bottom that described filter part is connected round platform portion 2 by tube 1 one end is constituted, round platform portion 2 base diameter is more than tube 1 external diameter, and the other end of tube 1 is fixed on described base 3；The fibre core of described optical fiber 5 is resisted against bottom round platform portion 2 through base 3 and tube 1；Also including lens 6, described lens 6 set the cylinder of cavity one end open in being, lens 6 cover on described filter part, and open at one end is closed with described base 3 and is connected.Cavity in lens 6 be top be the cylinder of cambered surface.
Lens 6 and base 3 can be threaded connection, and lens 6 opening is provided with female thread, and the periphery of base 3 is provided with external screw thread with matching.Lens 6 and base 3 also can be coupled together by modes such as bonding or cutting ferrules.Purpose is to cover on fixing for lens 6 on filter part, because the lens of cylinder 6 serve optically focused effect, the arclight of greater angle scope can be made to be reflected into optical fiber through filter part by lens 6.
And the arclight sensor lens of such structure not only can make arclight be refracted to optical fiber 5 from the end of optical fiber 5 fibre core through the round platform portion 2 of lens 6 and filter part, arclight also can be made to be refracted to optical fiber 5 from the side of optical fiber 5 fibre core through the tube 1 of lens 6 and filter part, and detection angles is up to 275 ° 300 °.
It addition, also include connecting portion 4, connecting portion 4 acts primarily as fixation, and it is fixedly sleeved on optical fiber 5, and one end is connected with the bottom of described base 3, so that within end does not has the fibre core of the optical fiber 5 of sheath to be fixed on filter part by base 3.Connecting portion can be selected for metal flange, is connected bottom base 3 by the external screw thread on ring flange.
In the present embodiment, the size of each parts is as follows: the external diameter of tube 1 is 3.8mm, and internal diameter is 2.5mm, a length of 8.2mm；Round platform portion 2 base diameter is 5.9mm, and top diameter is 5.5mm, and height is 1.6mm.Lens 6 external diameter is 12mm, and height is 20mm；Cavity cylinder basal diameter in lens 6 is 6.5mm, and height is 11.5mm.
During the arclight produced when an accident occurs, arclight is condensed to filter part through lens 6, need ultraviolet light or the visible ray leaching in arclight again according to detection by filter part, again by optical fiber 5 by the optical signal transmission that detects to optical-electrical converter, then the control unit at optical-electrical converter place sends trip command to chopper, and total time only needs several milliseconds.
