Description
RE-H35 is a professional all-in-one high voltage surge signal generator designed for flashover method fault location and high resistance fault burn-through pretreatment of 10kV~35kV XLPE, oil-impregnated paper and PVC power cables. It is widely used in power operation and maintenance teams, cable construction companies, industrial enterprises and municipal engineering departments for cable fault rush repair and preventive test. It strictly complies with DL/T 849.1-2019, GB/T 12706.1-2020 and DL/T 596-2021 standards, adopting highly integrated design that integrates high voltage rectifier unit, energy storage capacitor, discharge mechanism and control system into a single chassis, eliminating the need for external capacitors and complex wiring, greatly improving on-site test efficiency and operation safety.
The instrument delivers 0~-35kV continuously adjustable negative DC output with a built-in 4μF/35kV standard energy storage capacitor, supporting maximum 2480J discharge energy. It adopts controlled gap discharge technology to generate standard surge high voltage, which breaks down the cable fault point to produce flashover discharge, and cooperates with the cable fault tester to complete accurate fault distance measurement. It supports three working modes: DC output, single discharge and periodic discharge, adapting to different fault types and test requirements. The built-in 7-inch color touch screen realizes intuitive man-machine interaction, and the built-in automatic discharge device ensures zero residual voltage after shutdown, eliminating safety hazards.

FAQ
Q: What is the function of the high voltage signal generator in cable fault detection?
A: The high voltage signal generator is the core power equipment for cable fault flashover test. It applies DC high voltage to the cable to charge the energy storage capacitor, and breaks down the fault point through gap discharge to generate flashover arc. The cable fault tester collects the discharge traveling wave signal and calculates the fault distance through waveform analysis. It is mainly used for detection of high resistance and flashover faults that cannot be located by low-voltage pulse method.
Q: What are the three working modes used for?
A: The three modes correspond to different test requirements:
- DC output mode: Continuous DC high voltage output, used for burn-through pretreatment of high resistance faults and DC withstand voltage test
- Single discharge mode: One discharge per trigger, used for precise waveform acquisition and fault distance measurement
- Periodic discharge mode: Automatic cyclic discharge at set intervals, used for continuous flashover test and fault pinpointing
Q: What safety matters should be paid attention to during on-site operation?
A: 1. The equipment must be reliably grounded before operation, and the other end of the cable must be properly guarded to prevent others from approaching; 2. Operators must maintain a safe distance from the high-voltage output terminal during high-voltage output; 3. In case of emergency, press the emergency stop button immediately, and the equipment will automatically discharge; 4. Although the equipment has built-in automatic discharge, it is still necessary to confirm zero voltage before touching the high-voltage end after shutdown; 5. The test must be carried out after confirming that the cable is completely powered off.
