3Acoustic magnetic digital synchronous fixed-point instrument

1.Purpose:

This product is used for rapid and precise positioning of buried electrical insulation fault points, as well as accurate detection of cable burial paths and depths.

2.Key Features:

1. The use of special structured acoustic vibration sensors and low-noise specialized devices as preamplifiers greatly improves the sensitivity of instrument positioning and path detection. In signal processing technology, the distance between the fault point and the sensing probe is displayed digitally, greatly eliminating the blindness during fixed-point operation.

2. When a faulty cable is overhead in a cable trench, the vibration sound of the entire cable makes it impossible for any fixed-point instrument to determine the specific location of the closed fault. Nowadays, as long as the sensor probe of this instrument is in contact with the faulty cable or nearby cable, the distance and direction of the fault can be accurately displayed, and the fault location can be easily and quickly determined.

3. The power frequency adaptive cancellation theory and high power frequency notch technology greatly enhance the suppression and anti-interference ability of 50Hz power frequency signals in strong power frequency electric field environments, and reduce fixed-point blind spots. In terms of instrument functionality, the use of acoustic electric synchronous reception and display technology effectively overcomes the difficulty of fixed-point positioning caused by environmental noise interference in the fixed-point site. Especially the digital display of fault distance eliminates the need for operators to analyze and judge complex waveforms, and to a considerable extent replaces the rough distance measurement function of the flash tester. For hundreds of meters long faulty cables, it is generally not necessary to conduct rough measurements to implement fixed points, which truly achieves high efficiency, speed, and accuracy. The use of 15z amplitude modulated electromagnetic waves and amplitude detection technology for path detection and cable burial depth measurement avoids the interference of television line frequency on the fixed-point instrument when the original equal amplitude 15z signal source is used.

4. The operation is extremely simple, just turn on the power switch, there is no need to shift gears or select functions. Compact, compact, modular, easy to carry and repair, with powerful functions.

3. Electromagnetic channel gain>110dB (300000 times).

4. The sensitivity of the electromagnetic channel receiver is less than 5 μ V.

5. The gain of the audio channel amplifier is less than 120dB (1 million times when the signal-to-noise ratio is 4:1).

6.50Hz power frequency suppression is greater than 40dB (100 times).

7. Sound electric synchronous display monitoring: When the site is fixed, the digital screen repeats counting once under the action of the impact electromagnetic wave formed by the impact high voltage, and displays the fault distance or full brightness (500.0 meters). At the same time, high impedance headphones are used to monitor the seismic waves generated by sparks at the cable fault point during impact discharge to eliminate environmental noise interference.

When replacing the acoustic sensor probe with a 15KHz electromagnetic sensor probe, it can accurately detect the cable path and cable burial depth.
