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.
The fault detector consists of a signal transmitter, a signal receiver, a probe, a plug and other parts. The transmitter and receiver are small in size, reasonable in structure, and beautiful in appearance.
Technical performance
Receiver
|
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. |
