YNDL-1008 multiple pulse cable fault tester (multiple pulse cable fault tester) is composed of ranging host and pulse coupling unit. This product is the opportunity of our company's rapid progress in the power industry, according to industry development and market demand , R & D and production of power cable fault testing system equipment. It is mainly used to test the open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults of power cables, as well as the accurate test of open circuit and short circuit faults of coaxial communication cables and local telephone cables; it can also measure the speed of electric waves. , Measure the cable length, etc., and establish cable files for daily maintenance and management.
The multi-pulse core technology based on TDR technology has completely changed the traditional test method, so that the previously difficult high-impedance fault waveform reading problem can be fundamentally solved. After the multi-pulse generator, any complex high-impedance The waveform is transformed into a very familiar and easy-to-identify low-voltage pulse short-circuit fault waveform, which completely solves the problem that users cannot identify complex and high-impedance fault waveforms for a long time, and improves the key rough measurement level.
The product adopts the international high-level time domain reflectometry (TDR) technology, the fault waveform is automatically judged, simple and clear, and convenient and pleasant to use; the whole machine adopts an industrial-grade black safety protection box design with a protection level of IP67, which is small and exquisite and easy to carry; The man-machine interface is friendly, and you can still be familiar with and use it quickly, and accurately complete the cable fault test work.
This product is an important component of equipment that uses multiple pulse method technology to complete the test. It uses resistance-capacitance characteristics to "temporarily store" part of the impact energy. Lead the impact high voltage signal to the fault phase of the faulty cable, and instantly reapply the "stored" part of the energy to the fault phase of the faulty cable to ensure the full breakdown of the fault point, forming and prolonging the arc and continuity after the fault is clicked through Time, generate a trigger at the same time and start multiple pulse automatic trigger device and TDR cable fault comprehensive tester (according to the TDR test method selection, the three pulse waveforms and the multiple pulse waveforms can be tested separately).
1. It is used for various faults of power cables of different grades, different cross-sections, different media and various materials of 35kV and below, including: open circuit, short circuit, low resistance, high resistance leakage, high resistance flashover fault.
2. The low-voltage pulse method, impact flashover method, three-pulse method, multiple-pulse method, and speed measurement method of traditional cable fault testing can be realized with high-voltage equipment.
3. Full Chinese operating software and user interface, sub-menu mode and text prompts to achieve human-computer interaction.
4. Industrial-grade 10.4-inch color touch LCD screen display, full Chinese operating software and user interface, sub-menu mode and text prompts to achieve human-computer interaction.
5. The global and local waveforms are displayed simultaneously, which is convenient for overall analysis and detailed adjustment.
6. Any high-resistance fault has simple waveform characteristics similar to low-voltage pulse short-circuit faults, which is very easy to interpret.
7. When the multiple pulse method is used for testing, the interface collects 8 real waveforms at the same time, which is more convenient for interpretation, reduces test errors, and improves test accuracy.
8. Built-in power supply, it can be used for a long time in the environment without power supply.
9. Industrial-grade black safety protection box design, protection grade IP67, small size, light weight, easy to use, high failure detection success rate and high test accuracy.
10. Stable performance in any environment, no crashes, signal acquisition and high-voltage protection measures are safe.
11. Built-in storage/recall function, which is convenient for saving or recalling data and waveforms for re-analysis.
12. The test signal provides a variety of pulse widths, and there is no test blind zone.
