XHHD523L Cable Outer Sheath Locator Precise Positioning Cable Shealt Fault Point
XHHD523L Cable Sheath Fault Pinpoint Locator
With the full development of urban network transformation, many power supply bureaus, construction parties, and even design units are encountering XLPE cables with a voltage level of 110kV and above for the first time. Due to time constraints and lack of experience, many cables cannot pass through the outer sheath after laying. Voltage test (10kV/1min). At present, the outer sheath is mostly made of HDPE sheath material, which has passed the DC 25kV/5min withstand voltage test in the factory, and the leakage current is as low as tens of μA. Therefore, most of the defects after laying are caused by external force damage during laying, including filling and covering. Defects after operation usually include termite bites; water entering the grounding box; deterioration of the original defect point; moisture penetration of the bifurcated part of the grounding wire to reduce the insulation resistance, etc. Sometimes because the cable is buried too deep or the surrounding conditions are complicated, the It is very difficult to locate, and some defects cannot be solved after many years, leaving hidden dangers to the operation. The output voltage of the high-voltage cable sheath fault detector XHHD523L is 10kV and below, which fully meets the requirements of the Chinese national standard GB50150-2006 for the withstand voltage test of the cable sheath, including the cable sheath handover test and preventive testing for cross-connection systems. Test and fault location of the cable outer sheath. Quickly and accurately find hidden dangers such as 10kv-500kv single-core and three-core high-voltage and ultra-high-voltage cable outer sheath grounding faults and large leakage currents. At the same time, it can perform 5kv-10kv, 1 Minute DC withstand voltage test is a special instrument necessary for cable equipment maintenance of 10kv-500kv single-core and three-core high-voltage and ultra-high voltage cable operation units, ultra-high voltage cable engineering companies, and various power transmission and transformation engineering companies.

Main Features:
1 With over-current, over-voltage, over-heat automatic protection function; 2 It is safer and more reliable to have zero-position start-up protection; 3 Unique self-discharge design, as long as the high voltage output is cut off, its own high voltage will be zero; 4. With current and voltage double-pointer display, intuitive and clear; 5 One-key switch between positioning mode and withstand voltage mode, which is convenient and quick; 6 There is no blind area in the test range; 7 The sensitivity of the receiver is adjustable, which is more convenient for positioning; 8 Over-current protection switch function, withstand voltage mode and positioning mode are convenient to use.

Working principle Positioning The full-wave rectification of the AC220V mains has achieved excellent conversion and transformed into a high-power special signal required for identification. This signal is added to the cable to be located through the connecting line, and the "step voltage method" or "current method" can be used. Pinpoint cable faults with precision.
Pressure function Switch the function key to the withstand voltage function, it can output 0-10kV voltage, and carry out the withstand voltage test on the cable.

① High voltage output: dedicated DC high voltage output terminal;
② Voltmeter: high voltage output voltage indicating kV meter;
③ Ammeter: output current indicating mA meter;
④ Fuse socket: the place where the fuse of the 220VAC power supply system is installed;
⑤ Power socket: working power supply of the instrument, 220VAC connection port;
⑥ Power switch: "I gear" uses AC220V power supply to supply power to the system; "0 gear" shuts down;
⑦ Frequency adjustment in positioning mode: adjust the pulse output frequency in positioning mode;
⑧ Voltage adjustment: After starting the device, you must first turn the knob counterclockwise to the end. When the high voltage start button light is on, press the start button, and then adjust clockwise to increase the output high voltage from small to large, and adjust counterclockwise to make the output high voltage decrease from large to small;
⑨ High-voltage stop button: When the test is completed or there is an abnormality, press this button to cut off the high-voltage output, the high-voltage light will be off, the stop button light will be on to indicate that there is high-voltage output, and if it is off, it means that there is no high-voltage output;
⑩ High voltage start button: When the start button light is on, it means that the voltage output is in the zero position. When the start button is on, the start button is valid. If the start button light is not on after turning on the power switch, adjust the voltage adjustment knob counterclockwise until the light is on. When the light is on, press this key to start the device and generate high voltage output;
⑪ Overcurrent protection switch: When the blue light is on, the overcurrent protection is turned on, and when the blue light is off, the overcurrent protection is turned off.
⑫ Positioning/withstand voltage function switch button: when the red light is on, it is the withstand voltage function, and when the green light is on, it is the positioning function;
⑬ Grounding column: instrument grounding point, safety protection;
