Introduction
The underground cable fault detector is designed by domestic
professional R&D team. It integrates the most advanced technologies such as
ultra-narrowband filters. Pipeline inspection, pipeline management
and maintenance, municipal planning and construction, power supply and other
departments of pipeline inspection, it is one of the necessary equipment for
pipeline maintenance units.
Features
Multi-function
1. Transmitter function: It has three signal
application modes: induction method, direct method and clamp method, which are
suitable for different occasions.
2. Receiver function: It is used to detect the
position, direction and depth of the underground cable.
3. The left and right positioning arrows
indicate the position of the target cable, and the positioning is fast and
accurate; the front and rear arrows and the dB value indicate the position and
size of the cable fault point.
4. With backlight function, it is suitable for
night rescue.
5. Accurate positioning for the buried cable
fault point
6. Current measurement: Measure the current
applied by the transmitter to the cable under test.
7. Multi- meter function: can measure output
voltage, current, impedance and power. And test cable continuity and insulation
quality during the detecting cable fault process.
8. External inductive clamp: suitable for
detecting the cable cannot be directly connected to the application of the
signal.
High accurate positioning
Multiple measurement modes for cable
positioning (valley mode, peak mode, wide peak mode, peak arrow mode) can be
mutually verified to ensure cable positioning accuracy.
1. Maximum value method: The peak component,
wide peak mode, and peak arrow mode can be used to determine the change of the
horizontal component or the horizontal gradient, according to the position of
the maximum value;
2. Minimum value method: In the valley mode,
by measuring the change of the vertical component, it is positioned according
to the position of its minimum value.
Many sounding methods
A variety of sounding methods are optional and
can be mutually verified.
1. Double horizontal coil direct reading method;
2. Single horizontal coil 80% method, 50%
method.
Strong anti-interference
1. Many observation parameters: It can measure
horizontal component, vertical component and horizontal gradient.
2. The transmission power is large: the
transmitter output power is up to 10W and continuously adjustable, arbitrarily
selected according to needs.
3. More working frequency:
Transmitter frequency: 128 Hz, 512 Hz, 1 KHz,
2 KHz, 8 KHz, 33 KHz, 65 KHz, 83 KHz.
Receiver frequency: radio, 50Hz, 100Hz, 512Hz,
1KHz, 2KHz, 8KHz, 33KHz, 65KHz, 83KHz (the instrument model is different, the
receiving frequency is also different).
Select the appropriate operating frequency
based on the target cable characteristics (material, structure, depth, length,
etc.) and environment.
Easy operation
1. Intuitive: Using a graphic display, it can
continuously and real-time display various parameters and signal strength
during the detection process.
2. Automatic: Automatically switch to the dual
horizontal antenna mode when measuring depth, and automatically adjust the
receiver sensitivity to make the measurement signal reach the best. The
sounding is automatically restored to the working mode before the sounding.
Continuously working time with low cost use
The transmitter is equipped with a large-capacity
lithium battery pack, which can meet the power supply needs of the field for
one working day, and can be recycled, It greatly reduces the detection cost.
AC, DC Dual use of the transmitter
Under normal conditions, if the
transmitter battery is fully charged, we use the built-in battery pack to
supply power. If the transmitter battery is insufficient during the use, but
the detection task is not completed, you can directly connect a dedicated power
adapter, and the instrument can be used normally without waiting for the
instrument to be fully charged.
