Description
Technical field
The utility model belongs to cable detection technical field, especially a kind of instrument that target cable is selected from multi-cable.
Background technology
Existing cable identifier is many receives pincers and indicating gauge three parts form by signal generator and signal, signal generator mainly produces special pulse-modulated signal, add on tested cable out of service by output line, find at the scene tested cable with receiving pincers, when receiving pincers, signal measures while being applied on cable distinctive signal, on signal detector meter pointer with apply signal frequency and synchronize and swing, the signal detecting on other cable is much smaller and opposite direction, by ammeter indicator range and direction, judge tested cable.
This cable identifier has certain shortcoming, signal receives pincers and comprises magnetic core and coiling, receive pincers for larger signal, will be very heavy, just very inconvenient in the time of work high above the ground, in addition, sort signal receives and clamps the restriction that is subject to cable size, on market, larger signal receives jaw footpath in 150mm left and right now, for the high-tension cable that is greater than 160mm diameter, signal receives pincers cannot closedly form closed magnetic circuit, cannot detect clear signal, measure minor diameter can because of signal receive pincers coil from cable compared with away from and make signal not obvious, so versatility is not good.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of novel cable identifier is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of novel cable identifier, it is characterized in that comprising the signal generator that sends direct current signal, the signal output plus terminal of signal generator is connected with the heart yearn of tested cable near-end, the negativing ending grounding of signal generator, the heart yearn ground connection of tested cable far-end and signal generator ground connection negative terminal form loop, the armouring at tested cable two ends disconnects with ground, is placed with the signal sentinel of differentiating tested cable current by needle above tested cable.
And described signal generator comprises the direct current unit that sends stable DC signal and the pulse unit that sends Unidirectional direct-current pulse signal, the current signal strength that signal generator sends regulates by adjusting knob.
And described signal sentinel comprises the square casing of hollow, be fixedly mounted with around thimble and make the needle horizontally rotating by being packed in thimble on housing base plate at the middle part of housing, on the lateral wall of housing, be shaped with the bar magnet of spinning in and out housing.
Advantage of the present utility model and good effect are:
1, the utility model versatility is good, and signal sentinel can be identified the cable of nearly all diameter, and the little electric wire to diameter 1mm is large to cable more than 200mm, can identify.
2, the utility model signal sentinel collection signal receives and is instructed in one, very small and exquisite portable, can put in pocket, brings great convenience to work high above the ground and zanjon operation, is that other cable identifiers are beyond one's reach.
3, operation is very simple, tional identification instrument need to lift cable just and signal identification pincers can be blocked to cable, lift for cable needs two people that are greater than 150mm, one people surveys, and this novel cable identifier only need to be placed on signal sentinel on cable, do not need to lift cable, one man operation.

Fig. 2 is signal generator theory diagram;
Fig. 3 is signal sentinel structural drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is implemented to be further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of novel cable identifier, as shown in Figure 1, comprise the signal generator that sends direct current signal, the signal output plus terminal of signal generator is connected with the heart yearn of tested cable near-end, negativing ending grounding, the heart yearn ground connection of tested cable far-end and signal generator ground connection negative terminal form loop, and the armouring at tested cable two ends disconnects with ground, is placed with the signal sentinel of differentiating tested cable current by needle above tested cable.
In concrete enforcement of the present utility model, as shown in Figure 2, described signal generator comprises the direct current unit that sends stable DC signal and the pulse unit that sends Unidirectional direct-current pulse signal, the current signal strength that signal generator sends regulates by adjusting knob, in actual measurement of the present utility model, the current signal strength that signal generator sends is tentatively definite according to the specification of tested cable, signal generator send after current signal will be in tested cable generation current, but the size of electric current not only depends on specification and the length of cable, but also depend on the electric conductivity of the earth that forms a loop part, therefore, adjusting knob is answered the output power of ascending progressively conditioning signal generator, until existence and the variation of the obvious sensory current of described signal sentinel.In actual measurement of the present utility model, the stable DC signal that direct current unit sends, the selected tested cable for the deflection of signal sentinel needle, the Unidirectional direct-current pulse signal that pulse unit sends, further confirms selected tested cable for the deflection vibrations of signal sentinel needle.
In concrete enforcement of the present utility model, as shown in Figure 2, described signal sentinel comprises the square casing 2 of hollow, be fixedly mounted with around thimble and make the needle 4 horizontally rotating by being packed in thimble 3 on housing base plate at the middle part of housing, on the lateral wall of housing, be shaped with the bar magnet 1 of spinning in and out housing, in actual measurement of the present utility model, first signal sentinel level is placed on tested cable, now due to the effect of terrestrial magnetic field, in signal sentinel, the direction of needle will be pointed to magnetic direction, progressively precession bar magnet is intervened surrounding magnetic field, change magnetic course to consistent with tested cable direction, then be that tested cable applies electric current by signal generator, the electric current applying will produce the sensing of magnetic field change needle, just can judge that by the change of magnetic course that is tested cable in numerous cables.
