Description
The hidden line buried line fault detector is a special instrument for power, broadcasting, post and telecommunications departments, as well as industrial and mining, rural areas to find underground cables, including direct buried armored cable lines and buried line faults. It can detect the direction of the buried line, the more accurate underground position, the basic buried depth, and various ground leakage faults, broken core faults, including lines under paddy fields, cement roads, bricks and stones, asphalt roads, and lines in the walls of buildings. Waterproof wires and cables used on the ground can be detected by using this instrument through appropriate methods.
Transmitter
| The transmitter panel is equipped with "power switch", "power indication"; "output selection", "high, medium, low"; "output indication" and "K measurement" switching switches, and the indicator light indicates the switching position; "output·KΩ measurement" shares an output terminal, which is switched by the "output·indication" and "KΩ measurement" switches; set "output 2" output terminal; square meter head indicates output and KΩ resistance. It can check the line on, off, mixed, and measure the size of the ground leakage resistance. | |
| Output signal form | pulse period 1.34±0.15mS. Width 0.2 ±0.1mS intermittent period 1.8±1S. |
| Output voltage | pulse period Upp high range greater than 1000V, medium range greater than 60V, low range greater than 30V. |
| KΩ measurement | It can check the side line on, off, mixed and leakage group size, and determine the nature of the fault. |
| The "output 2" output terminal | It can output peak pulse short-circuit current 1-5A. |
| Output power | Pulse power greater than 2.5W (when high-end load resistance is 80KΩ). |
| Power supply | 8.4V. |
| Set power switch, power indicator, "high gear", "low gear" switch; when there is a signal on the meter, it indicates the positive direction or negative direction; there is an input terminal on the upper side, which can be inserted into the probe or plug-in plug respectively. |
|
| Received signal form | pulse period 1.360.15mS |
| width 0.20.1mS, intermittent period 1.81S. | |
| Power supply | 6V (4 No. 5 batteries) |
| Detection fault range and detection accuracy | When the detection length is 3km, the burial depth is 2m short circuit to the ground, and the leakage resistance of the leakage fault is less than 500kΩ, the insertion measurement positioning error is less than 0.2m. |
| When detecting a broken core fault with a length of 1km and a burial depth of 2m and good insulation to the ground, the inspection positioning error is less than 0.4m. | |
| The actual detection length can exceed 1-5km and the burial depth is 2-3m. | |
| Anti-interference performance | The received signal is clear and can detect underground wire faults under 220 kV lines. |
| Instrument working conditions | This instrument can work continuously in an environment with an ambient temperature of -15 and an atmospheric pressure of 86-108Kpa. |
