Description
Technical field
The utility model is related to cable detection technical field more particularly to a kind of electrification copper core cable detection devices.
Background technology
At present, the conventional substation of operation has a large amount of control cable and power cable, in transformation or enlarging, with
Toward construction in treat the operation cable torn open without effective detection means, can only come by the cable marking board that leaves of constructing early period
It distinguishes, i.e., operation cable is detected by original nameplate, the current potential of the charging operation cable is measured with multimeter.
But program inefficiency, can not live detection, any work（Including preliminary preparation）It must have a power failure
It can just carry out afterwards, waste a large amount of manpower and materials.Especially only several cables often occur in some public screen cabinets needs
It removes, shields other cables of cabinet also in charging operation, at this time often will appear the phenomenon that tearing wrong cable open, gently then cause to protect
Device dead electricity, protection false positive signal, it is heavy then cause protective device not move, no-voltage of entire station, cause a serious accident.
Utility model content
The purpose of this utility model be to provide it is a kind of electrification copper core cable detection device, can in the case that electrification safety,
Accurately and rapidly cable is carried out to line, greatly improve operating efficiency.
The technical solution adopted in the utility model is：
A kind of electrification copper core cable detection device, connects including sonic generator, acoustic receiver, the first connecting pin, second
Connect end, processor and warning indicator, the sonic generator go out wave mouth and acoustic receiver into Bo Kou be metal end
Mouthful, and external screw thread is provided with outside metal port；One end of first connecting pin is provided with nut set, nut set internal thread and metal
Port external screw thread matches, and the other end end set of the first connecting pin has insulation division, and first connecting pin connects with second
It is identical to connect end structure size；The sonic generator connects one end of live electric cable to be measured by the first connecting pin, and sound wave connects
Receive the other end that device connects live electric cable to be measured by second connection end；The output terminal connection processing device of the acoustic receiver
Input terminal, the input terminal of the output terminal link warning indicator of processor.
The insulation division is provided with sealing screw thread for the outer wall of cone and conical end.
The frequency of sound wave of the sonic generator is 16000 Hz---30000 Hz.
The utility model is transmitted by sound wave in copper core, applies certain frequency sound wave in operation cable side, cable is another
Outer side receives sound wave, accurately detects the root cable, using acoustic-electric isolating device, prevents the interference of electricity, is also prevented from simultaneously
Protective device is caused to cause to seal in current potential, protective device is caused to malfunction.
Description of the drawings
Fig. 1 is the utility model electrical principle block diagram.
Specific embodiment
As shown in Figure 1, the utility model include sonic generator, acoustic receiver, the first connecting pin, second connection end,
Processor and warning indicator, the sonic generator go out wave mouth and acoustic receiver into Bo Kou be metal port, and
External screw thread is provided with outside metal port；One end of first connecting pin is provided with nut set, nut set internal thread and metal port
External screw thread matches, and the other end end set of the first connecting pin has insulation division, first connecting pin and second connection end
Structure size is identical；The sonic generator connects one end of live electric cable to be measured, acoustic receiver by the first connecting pin
The other end of live electric cable to be measured is connected by second connection end；The input of the output terminal connection processing device of the acoustic receiver
End, the input terminal of the output terminal link warning indicator of processor.
The insulation division is provided with sealing screw thread for the outer wall of cone and conical end.
The frequency of sound wave of the sonic generator is 16000 Hz---30000 Hz.
When the utility model at work, one end sends out the frequency specified, and is the situation of copper core cable for control cable,
It determines to be suitble to the frequency transmitted in copper cable, generator front end is insulating materials, can be in direct contact live electric cable core, pass through
Core is charged, sound wave is transmitted in copper core, is received in other end using acoustic receiver, receiver front end is also exhausted
Edge material can be in direct contact electrification core, when other end of receiver receives corresponding acoustic signals, then by number
Secondary start and stop can accurately detected core to be taken out stitches.
Supersonic generator sends out the frequency specified in the utility model, is the feelings of copper core cable for control cable
Condition determines to be suitble to the frequency transmitted in copper cable, and generator front end is insulating materials, can be in direct contact live electric cable core,
By charging core, sound wave is transmitted in copper core, is received in other end using acoustic receiver, receiver front end
For insulating materials, electrification core can be in direct contact, when other end of receiver receives corresponding acoustic signals, is then passed through
After start and stop for several times, core to be taken out stitches can accurately detected
According to the actual conditions of construction site, after sound wave monitoring live electric cable system application, reorganization and expansion can be significantly reduced
The construction risk of substation, while human and material resources, financial resources are saved, realize reorganization and expansion substation.Working efficiency is greatly improved,
Economic benefit highly significant.This system application market is extensive, and social benefit is huge.
