Description
Technical field
The utility model relates to electric arc technical field of light detection, is specially a kind of cylindrical arclight sensor lens.
Background technology
Once break down in electric system, huge arclight will be produced, produce very large luminous energy radiation and very high temperature radiation when arclight occurs, these radiation have very large destruction to electric system, sometimes also can cause the casualty accident of operating personnel.The extent of injury of arclight depends on the duration of arclight, as long as so can to limit fast 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 current arclight sensor on the market can only monitor about 135 °, dead ahead conducts the light signal of coming; must by the front of arc photosensor camera lens just to the check point needing to detect when installing; when having multiple check point; just need multiple arclight sensor is installed; if Rig up error; be easy to cause the arclight not receiving check point and send, thus do not have the effect of electric arc protection.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide the one that a kind of detection angles is larger cylindrical arclight sensor lens, and technical scheme is as follows:
A kind of cylindrical arclight sensor lens, comprises filter part, optical fiber and base, and the bottom that described filter part connects round platform portion by tube one end is formed, and round platform portion base diameter is greater 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 comprise lens, the right cylinder of cavity one end open established by described lens 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, and length is 8.2mm; Described round platform portion base diameter is 5.9mm, and top diameter is 5.5mm, is highly 1.6mm; Described lens external diameter is 12mm, is highly 20mm.
Further, the right cylinder of to be top the be cambered surface of the cavity in described lens.
Further, the cavity right cylinder basal diameter in described lens is 6.5mm, is highly 11.5mm.
Further, also comprise connecting portion, described connecting portion is fixedly sleeved on described optical fiber, and connecting portion one end is connected with described base.
The beneficial effects of the utility model are: the cylindrical arclight sensor lens that the utility model provides can make detection angles increase to 275 °-300 °, the arc optical signal of multiple check 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.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: a kind of cylindrical arclight sensor lens, comprise filter part, optical fiber 5 and base 3, the bottom that described filter part connects round platform portion 2 by tube 1 one end is formed, round platform portion 2 base diameter is greater 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 comprise lens 6, the right cylinder of cavity one end open established by described lens 6 in being, lens 6 cover on described filter part, and open at one end is closed with described base 3 and is connected.The right cylinder of to be top the be cambered surface of the cavity in lens 6.
Lens 6 and base 3 are by being threaded, and lens 6 openend is provided with internal thread, and the outer of base 3 is arranged with external thread with matching.Lens 6 and base 3 also couple together by modes such as bonding or cutting ferrules.Object is by lens 6 fixed cover on filter part, because columniform lens 6 serve optically focused effect, the arclight scioptics 6 of greater angle scope can be made to reflect into optical fiber through filter part.
And the arclight sensor lens of structure like this not only can make arclight be refracted to optical fiber 5 through the round platform portion 2 of lens 6 and filter part from the end of optical fiber 5 fibre core, arclight also can be made to be refracted to optical fiber 5 through the tube 1 of lens 6 and filter part from the side of optical fiber 5 fibre core, and detection angles can reach 275 °-300 °.
In addition, also comprise connecting portion 4, connecting portion 4 mainly plays fixation, and it is fixedly sleeved on optical fiber 5, and one end is connected with the bottom of described base 3, thus makes end not have the fibre core of the optical fiber 5 of sheath to be fixed within filter part by base 3.Connecting portion 4 can select metal flange, is connected with bottom base 3 by the external 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, and length is 8.2mm; Round platform portion 2 base diameter is 5.9mm, and top diameter is 5.5mm, is highly 1.6mm.Lens 6 external diameter is 12mm, is highly 20mm; Cavity right cylinder basal diameter in lens 6 is 6.5mm, is highly 11.5mm.
During the arclight produced when an accident occurs, arclight is condensed to filter part through lens 6, needed to leach the ultraviolet light in arclight or visible ray according to detection by filter part again, again by optical fiber 5 by the optical signal transmission that detects to photoelectric commutator, then the control module at photoelectric commutator place sends trip command to isolating switch, and T.T. only needs several milliseconds.
