Description
Technical field
The utility model relates to the device technique field of exploration cable fault, particularly relates to a kind of underground cable troubleshooting device.
Background technology
At present, high-tension cable uses and day by day increases in 10KV transmission line of electricity, and high-tension cable is operated in high voltage due to it, under big current, is easily short-circuited, the faults such as ground connection, and again because it is embedded in underground more, searching of trouble spot is very difficult; Electric company at county level more works searching of the cable fault that relates to pressure common cable and underground cable, underground line and indoor concealed wire, if searching of these faults is also difficult to search without instrument, current electric company at county level is when cable breaks down, generally using the high-tension cable disabled vehicle of city-level electric company, is very inconvenience; The high-tension cable disabled vehicle of prior art, due to expensive, is difficult to universal for the moment.
Application number be 201220082997.6 a kind of cable fault that patent document discloses search instrument, above-mentioned instrument of searching only includes signal generator and signal receiver, in use there is following shortcoming: one, when not clear cable louding, because described in search the trend that instrument can not search cable, because this increasing the time finding cable louding, improve working strength, reduce work efficiency; Two, because there is no accumulator or portable power source, cause mobile use inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of underground cable troubleshooting device, described device positions by using the trend of cable tracer to cable, cable louding uses signal generator and the trouble spot of signal receiver to cable to position after having good positioning, locating speed is fast, reduce working strength, improve work efficiency, in addition because described device comprises accumulator, there is feature mobile easy to use.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of underground cable troubleshooting device, it is characterized in that: described device comprises signal generator, signal receiver, cable tracer and probe, the signal output part of described signal generator is electrically connected with one end of underground cable, the end of described probe is provided with probe, one end of probe is free end, the other end of probe is electrically connected with signal receiver through wire, described cable tracer is fixed on described probe, accumulator is provided with in described probe, the power output end of described accumulator is electrically connected with signal receiver and cable tracer respectively through switch, described switch is fixed on the outside of described probe.
Further technical scheme is: described switch is single-pole triple-throw (SPTT) switch.
Further technical scheme is: described probe is insulation rod.
The beneficial effect adopting technique scheme to produce is: described device positions by using the trend of cable tracer to cable, cable louding uses signal generator and the trouble spot of signal receiver to cable to position after having good positioning, locating speed is fast, reduce working strength, improve work efficiency, in addition because described device comprises accumulator, there is feature mobile easy to use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the electrical connection theory diagram of the utility model signal receiver and cable tracer;
Wherein: 1, signal generator 2, underground cable 3, probe 4, cable tracer 5, probe 6, switch 7, signal receiver 8, trouble spot 9, accumulator.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the utility model discloses a kind of underground cable troubleshooting device, described device comprises signal generator 1, signal receiver 7, cable tracer 4 and probe 5, and signal generator 1, signal receiver 7 and cable tracer 4 use instrument of the prior art.The signal output part of described signal generator 1 is electrically connected with one end of underground cable 2, the end of described probe 5 is provided with probe 3, one end of probe 3 is free end, the other end of probe 3 is electrically connected with signal receiver 7 through wire, described cable tracer 4 is fixed on described probe 5, described probe 5 is insulation rod, is provided with accumulator 9 in described probe 5.
As shown in Figure 2, the power output end of described accumulator 9 is electrically connected with signal receiver 7 and cable tracer 4 respectively through switch 6, and described switch 6 is fixed on the outside of described probe 5.Described switch 6 is single-pole triple-throw (SPTT) switch, when switch 6 gets to upper end, signal receiver 7 obtains electric work, can be used for acknowledge(ment) signal generator 1 send sound signal, when switch 6 gets to centre, for off position, when switch 6 gets to lower end, cable tracer 4 works, and can carry out cable trace location.
When using described device, first switch 6 is controlled, cable tracer 4 is worked, is judged the trend of cable by cable tracer 4, then control switch 6, signal receiver 7 is worked, and move towards along cable the power detecting the signal that the signal generator that receives sends, the closer to trouble spot, signal intensity is larger, when detecting signal intensity maximum point, this point is trouble spot.
Described device positions by using the trend of cable tracer to cable, cable louding uses signal generator and the trouble spot of signal receiver to cable to position after having good positioning, locating speed is fast, reduce working strength, improve work efficiency, in addition because described device comprises accumulator, there is feature mobile easy to use.
