Integrated cable fault location testing system locator XHHV535-2TX
This device is used to detect main insulation faults of power cables with voltage levels of 35kV and below; calibrate the cable length; and accurately detect the cable burial direction and depth.
This device is a cable fault location system that integrates a cable fault tester, a cable path meter transmitting module, a high-voltage pulse generator, and a large-capacity battery pack. It is mainly composed of four parts.
This cable fault location system is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flashover. Network failure.
The high-voltage pulse generator is powered by an internal battery pack or 220VAC. It includes DC withstand voltage, single pulse, and periodic pulse output functions. It also includes a signal feedback device to facilitate sampling of the cable meter host; it also includes zero-position protection, automatic discharge during shutdown, and other functions. See the High Voltage Pulse Generator section for detailed instructions.
Large-capacity battery pack: 12.6V battery pack, provides power supply for high-voltage pulse generator and cable path meter.
Cable fault tester, simple operation software interface, single chip centralized control, touch operation mode, built-in large-capacity lithium-ion battery, stable, reliable and easy to use. Use an independent power supply and power supply system to prevent power interference during impact discharge. See the cable fault tester section for details.
The cable path meter is powered by an internal battery pack, is easy to use, and includes overload protection, amplitude adjustment and other functions. See the Cable Path Gauge section for detailed instructions.
