Abstract
The utility model relates to a cable short circuit independent display, which comprises a casing and a rotor shaft arranged inside the casing. A transparent sector window is arranged on the casing, a red blade is assembled on the rotor shaft, circular permanent magnetic steel is arranged below the red blade and fixedly connected with the red blade, chargeable U-shaped magnetic steel is arranged below the circular permanent magnetic steel, and a magnetic charging coil is wound on the chargeable U-shaped magnetic steel. The cable short circuit independent display has the advantages of reducing range of fault points and being capable of accurately judging positions of faults and achieving fault detection and local display, and therefore the range for judging the cable fault points is reduced, work load for excavating rod surfaces is reduced, working efficiency is improved, so that maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of cable short circuit stand alone display.
Background technology
The power cable of under urban road, burying underground, after be short-circuited (dig disconnected, puncture), it is bad somewhere to judge which root cable rapidly, for efficiently apace recovery cable play important effect.In the prior art, the cable short circuit indicator adopts detector and displays separated technological, and detector can't the independent displaying failure message; After detector detects fault-signal, failure message sent to be presented on the alarm, detector can not independently use; And can't segmentation when feeder cable is longer install, definite position that also just can't failure judgement makes the increase of tracing for troubles point cost; The time of recovering electricity consumption increases, and the loss that causes increases.
The utility model content
The purpose of the utility model provides a kind of cable short circuit stand alone display, has remedied weak point of the prior art.
The purpose of the utility model is to realize through following technical scheme:
A kind of cable short circuit stand alone display; Comprise shell and cased 's armature spindle, said shell is provided with transparent fan-shaped window, is equipped with red blade on the said armature spindle; Red blade below is provided with circular permanent-magnet steel; Red blade is fixedly connected with circular permanent-magnet steel, and the below of circular permanent-magnet steel is provided with and can on the U-shaped magnet steel, be wound with towards magnetic coil towards the U-shaped magnet steel.
The beneficial effect of the utility model is: the scope of trouble spot has been dwindled; Accurate failure judgement position; Can realize fault finding and show on the spot, can dwindle the scope of judging Method of Cable Trouble Point like this, reduce the workload of excavating the road surface; Increase work efficiency, thereby reduce maintenance cost greatly.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described cable short circuit stand alone display of the utility model embodiment;
Fig. 2 is the synoptic diagram of the described cable short circuit stand alone display of the utility model embodiment under the circuit normal condition;
Fig. 3 is the synoptic diagram of the described cable short circuit stand alone display of the utility model embodiment under the fault state.
Among the figure:
1, shell; 2, armature spindle; 3, transparent fan-shaped window; 4, red blade; 5, circular permanent-magnet steel; 6, can be towards the U-shaped magnet steel; 7, towards magnetic coil.
Embodiment
Shown in Fig. 1-3, the described a kind of cable short circuit stand alone display of the utility model embodiment comprises shell 1 and the armature spindle 2 that is contained in shell 1 inside; Said shell 1 is provided with transparent fan-shaped window 3; Be equipped with red blade 4 on the said armature spindle 2, red blade 4 belows are provided with circular permanent-magnet steel 5, and red blade 4 is fixedly connected with circular permanent-magnet steel 5; The below of circular permanent-magnet steel 5 is provided with and can on U-shaped magnet steel 6, be wound with towards magnetic coil 7 towards U-shaped magnet steel 6.
Shown in the utility model be encased in the circuit through two ends towards magnetic coil 7; Can there is a natural attraction between the sexes with circular permanent-magnet steel 5 behind magnetic through overshoot magnetic coil 7 towards U-shaped magnet steel 6 under the normal condition as shown in Figure 2; Just in time transparent fan-shaped window 3 times, what see is black to the breach of red blade 4.
Under the malfunction as shown in Figure 3, opposite towards magnetic coil 7 towards the magnetoelectricity flow path direction (with both positive and negative polarity exchange under the normal condition).Can change (the N utmost point becomes the S utmost point) towards U-shaped magnet steel 6 the two poles of the earth magnetic poles; Like this can towards the polarity at U-shaped magnet steel 6 two just with circular permanent-magnet steel 5 on polarity identical, at this moment the same sex is repelled mutually, behind circular permanent-magnet steel 5 and the red blade 4 Rotate 180 degree; There is a natural attraction between the sexes; At this moment wherein a slice of 4 red blades just in time forwards transparent fan-shaped window 3 times to, shows red, can see the red-fault state very intuitively.
Multiple spot or long distance are not very real through lead collection failure message under the rugged environment at the scene, so adopt the utility model to survey and to show failure message timely, the time of trouble-shooting point and cost will significantly reduce, and easy for installation.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
