Abstract
The utility model discloses an arc light sensor probe, comprising a housing and a top cover. A cover plate of the top cover is provided with a lighting hole, the lighting hole is provided with an optical lens, a circuit board is installed in the housing, and the bottom of the housing is also provided with a permanent magnet. The arc light sensor probe is advantageous in that, since the bottom of the housing is provided with the permanent magnet, direct attraction of the arc light sensor probe onto an iron sheet switch cabinet is facilitated, and installation is convenient.
Description
Technical field
The utility model belongs to sensor field, is specifically related to a kind of sensor probe.
Background technology
Arc photosensor is a kind of photoinduction element.When ground connection or phase fault occur electric wiring, because having generation the burning of arc light, light intensity will increase suddenly.In arc photosensor, electronic component will be converted to electric signal by light signal, and passes to the auxiliary unit of arc protection.Arc light protecting device, after receiving arc optical signal, acts on protective device tripping operation through logic discrimination.Arc photosensor probe is arranged on the privileged site in switch cubicle, monitors those fragilities and vitals.As switch cubicle upper bus interval, switch cubicle bottom CT and PT parts, cable connector etc.
Arc photosensor probe is arranged in each compartment of switch cubicle, can realize to by simply in various complicated wiring, low-tension switch cabinet provides optionally and monitors, protects.Arc photosensor probe, as photoinduction element, will detect the light intensity increasing suddenly when there is arc fault, and convert light signal to current signal and send auxiliary unit to.
Different inside switch cabinet structures can be variant, and also there is difference the installation site of each vitals, when arc photosensor probe is installed, other servicing units need to be installed, and installs, reequips Comparision loaded down with trivial details.Once arc photosensor drops, its inner electronic component is easily damaged.
Summary of the invention
Given this, the utility model object is to provide a kind of arc photosensor easy for installation probe, resistance to the falling of this arc photosensor probe.
For solving above technical matters, the technical scheme that the utility model provides is, a kind of arc photosensor probe is provided, comprise shell and top cover, on the cover plate of described top cover, be provided with lightlng hole, on this lightlng hole, optical mirror slip is installed, circuit board is installed in shell, outer casing bottom is also provided with permanent magnet.
Further, in described shell, be provided with draw-in groove, described circuit board is fixed by draw-in groove.
Further, in described shell, be perfused with epoxy resin.
Preferably, described permanent magnet is installed in the enclosure.
Further, on the sidewall of described shell, be provided with wire hole.
Further, on the lateral wall of described shell, be provided with erecting frame, on the base plate of this erecting frame, be provided with mounting hole.
Preferably, the material of described shell is ABS plastic.
Preferably, described optical mirror slip is optical filtering.
Preferably, described optical filtering only can be by ultraviolet ray and visible ray.
Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
1, the utility model is installed magnet at outer casing bottom, is convenient to directly be adsorbed on iron sheet switch cubicle, easy for installation.
2, the practical epoxy resin perfusion of the utility model, fixing circuit board, has sensor probe anti-ly to fall, shockproof performance, adds practical ABS plastic shell, sensor probe is difficult for damaged.
3, the utility model, except available magnet is directly installed, also can be screwed, to meet the needs of specific installation environment.
4, the utility model optical mirror slip used is optical filtering, and this eyeglass only can make ultraviolet ray and visible ray pass through, the interference of light that like this can its all band of filtering, the sensitivity of raising sensor.
Accompanying drawing explanation
Fig. 1 is the front elevation of the utility model one preferred embodiment.
Fig. 2 is A-A cut-open view in Fig. 1.
Fig. 3 is the stereographic map of the utility model one preferred embodiment.
Fig. 4 is the exploded view of the utility model one preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and a specific embodiment, describe.
Referring to Fig. 1 to Fig. 4.The described arc photosensor probe of the present embodiment, comprises shell 1 and top cover 2.Shell 1 is tubbiness, and top cover 2 covers on shell 1.
On the cover plate of described top cover 2, be provided with lightlng hole, optical mirror slip 3 is installed on this lightlng hole, as preferred implementation, this optical mirror slip 3 is optical filtering, only can be by ultraviolet ray and visible ray, to prevent that other light from disturbing.
The mounting means of arc photosensor probe have two kinds available, the one, in shell 1 bottom, permanent magnet 5 is also installed, particularly permanent magnet 5 is arranged on to shell 1 inside, prevent that magnet 5 is separated with shell 1; The 2nd, an erecting frame 12 is set on the lateral wall of shell 1, on the base plate of this erecting frame 12, be provided with mounting hole 13, can be by screw, arc photosensor probe is fixing during installation.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, within not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
