Acoustic magnetic digital display synchronous fixed point instrument
intro
This product is used to quickly and accurately locate the fault point of the buried cable, and detect the buried path and depth of the cable (obtain the depth at the fault point).
Recurso principal
1, with a special structure of acoustic vibration sensor and low noise special devices for pre-amplification, improve the sensitivity of the instrument fixed point and path detection. In the signal processing technology, the distance between the fault point and the sensor is displayed digitally, which eliminates the blindness of the fixed point
2. When the overhead faulty cable in the cable trench is fixed, the vibration and sound of the whole cable make the fixed point instrument helpless and unable to determine the specific location of the closed fault. Now, as long as the sensor probe of the instrument touches the faulty cable or nearby cable, the fault distance and direction can be displayed, and the fault location can be quickly determined.
3, power frequency adaptive cancellation theory and high power frequency notch technology, strengthen the suppression and anti-interference ability of 50Hz power frequency signal in a strong power frequency electric field environment, and narrow the fixed-point blind area. In the function of the instrument, using the technology of acoustic and electric synchronous receiving and display, the fixed-point difficulty caused by the noise interference of the fixed-point field is overcome. Em particular, the digital display of fault distance saves the operator from analyzing and judging the complex waveform, and replaces the coarse distance measurement function of the flash gauge to a considerable extent. For hundreds of meters of fault cables, the fixed point can be implemented generally without rough measurement, which truly realizes high efficiency, rápido e preciso. 15kHz amplitude modulated electromagnetic wave and amplitude detection technology are used to detect the path and measure the buried depth of the cable, which avoids the interference of the TV line frequency to the fixed point instrument when the original 15kHz signal source is constant amplitude.
4, fácil de operar, open the power switch can be, no need to shift and function selection. Compact structure, compact, modular, easy to carry maintenance, large function.
