Huazheng HZ-R30 Cable Path Detector

I.Product Introduction

HZ-R30 cable path detector is a multi-functional cable path identification and detection instrument. It features multiple functions including cable path detection, cable identification, and cable grounding fault location (optional) . The instrument consists of a transmitter, transmitting current clamp, receiver , receiving flexible current clamp, connecting test leads, stethoscope (optional), and A-frame (optional accessory) .

Pipeline Path Detection: This instrument enables trenchless detection of metal pipelines and underground cables, facilitating pipeline surveys and depth measurements. Utilizing various filter technologies, it possesses strong anti-interference capabilities, enabling precise positioning and depth measurement. Suitable for detecting and inspecting various underground metal pipelines, pipeline management and maintenance, municipal planning and construction, and power supply departments, it is an essential instrument for pipeline maintenance units. This function is achieved through a signal transmitter, receiver, signal transmitting clamps, and connecting test leads. The instrument has the following features:

Multiple detection modes: classic positioning mode, full-screen signal mode, and signal curve mode.

Classic positioning mode: Compass, direction and signal amplitude display, intuitively showing the left and right direction of the pipeline.

Full-screen signal mode: 360° omnidirectional pipeline path indication, continuously displaying depth, current, and relative pipeline position. The interface is simple and intuitive, requiring no prior experience to operate.

Signal curve mode: Displays historical signal strength curves, allowing you to locate cables by observing changes in the curves.

Current direction determination (at some frequencies) can eliminate interference from adjacent lines and prevent tracking errors by calibrating the current direction.

The color of the pipeline simulation line displays the signal interference intensity in real time.

With a built-in frequency sweep test function, users can select a suitable signal frequency for pipeline measurement based on the frequency sweep results, avoiding interference from the same frequency.

Fully digital high-precision sampling processing: stable and reliable, ultra-high sensitivity, extremely narrow receiving bandwidth, strong anti-interference capability, and can effectively suppress power frequency and harmonic interference from nearby operating cables and pipelines.

Multiple detection frequencies: 10 active detection frequencies and 2 passive detection frequencies.

The transmitter offers multiple signal output methods: direct output, clamp coupling, and induction.

The transmitter features digital power amplification for high-power output, fully automatic impedance matching, and fully automatic protection.

Cable Identification: Designed to solve the technical problems of cable identification for power cable engineers and cable workers. It can identify live cables and de-energized cables. Users can accurately identify a target cable from multiple cables using the instrument, avoiding serious accidents caused by accidentally cutting live cables. During cable identification, 10 cables can be pre-marked at the transmitting end before being identified at the remote receiving end, greatly saving the time of engineers traveling back and forth and improving work efficiency. Successful cable identification is marked with a √, and non-target cables are marked with an ×, enabling fast and automatic identification of target cables. This function is achieved through the cooperation of a signal transmitter, receiver, signal transmitting clamp, connecting test leads, and flexible clamps.

Signal Transmitter : Used for pipeline path detection and cable identification. This device can apply identification signals to target cables through direct output, clamp coupling, and induction. Ten different pulse signals are available: 512Hz, 1024Hz, 640Hz (cable identification), 1280Hz, 2.56kHz (fault location), 3.20kHz, 8.19kHz, 33kHz, 82kHz, and 196kHz. The maximum signal output power is 10W, adjustable in 10 levels, adapting to different application environments and making pipeline detection and cable identification more accurate and reliable. The instrument has a built-in high-power rechargeable lithium battery, automatic impedance matching, and fully automatic protection. The main unit features a 5.6-inch color capacitive touchscreen LCD display, showing real-time dynamic signal output status and battery usage.

Transmitter clamp : Suitable for clamp coupling method. The transmitter clamp couples the signal emitted by the transmitter to the target cable. The clamp jaw size is Φ150mm . The transmitter clamp is directional, and the transmitted signal flows in from the direction indicated by the arrow on the transmitter clamp.

Receiver : Used for receiving signals for pipeline path detection and cable identification. It has multiple built-in shielded 3D antennas, capable of effectively identifying 10 different pulse-code current signals generated by the transmitter : 512Hz, 1024Hz, 640Hz, 1280Hz, 2.56kHz, 3.20kHz, 8.19kHz, 33kHz, 82kHz, and 196kHz . It can also identify 50Hz and 60Hz power frequency signals. A 3.5-inch color LCD screen provides real-time dynamic display of 360° omnidirectional pipeline path indication, depth, current, and relative pipeline position .

A-frame (optional) : An A-shaped voltage signal sensor specifically designed for locating grounding faults in buried cables. The A-frame's two probes or probe discs accurately receive step voltage signals transmitted from a transmitter. After data analysis at the receiver, the grounding fault point can be precisely located. The probes or probe discs are independently interchangeable ; the probes are suitable for muddy surfaces, while the probe discs are suitable for concrete surfaces where direct insertion into the ground is not possible. The A-frame's lead wires are designed with aviation sockets, allowing connection to the receiver via aviation plug cables. It is easily detachable and compatible with an independently designed handle, enabling the A-frame to function independently for other purposes.

Flexible current clamp : Used for cable identification. This current clamp uses a Rockwell coil and has excellent transient tracking capability, enabling rapid identification of pulse-coded currents generated by the transmitter. It is suitable for thick cables or irregularly shaped conductors. Its jaws have an inner diameter of 200 mm, allowing for non-contact measurement without disconnecting the circuit under test, ensuring safety and speed.
