Portable cable test and fault location system on low and medium voltage power cables
HM-300 full intelligent multi-pulse cable fault tester is catering to the rapid development of industrial-grade power industry solutions and IT era, using the industrial control embedded computer platform system, network service business, USB communication technology for the limitations of the original cable fault tester. Systematization greatly improves the use and utilization of the instrument and the convenient on-site environment operation. The biggest feature of the multi-pulse cable fault tester is to avoid the defects that 90% of the complex high-resistance fault waveform is difficult to read. The test software automatically recognizes the card bit to read the fault distance, especially for the increasing number of buried cable faults. Unique multi-program service and management learning software. The whole system meets the general technical conditions of the power equipment special test equipment of the People's Republic of China power industry standard "DL/T849.1 ~ DL/T849.3-2004", and the production follows the license of the manufacturing instrument of the People's Republic of China, Shaanxi 00000548, the set The equipment is a qualified supplier of the State Grid and China Southern Power Grid. The system test consists of four parts: system host, multiple pulse generator, fault locator and cable path instrument. It is used for testing various faults of power cables, cable path and cable burial depth. And accurate testing of railway airport signal control cables and streetlight cable faults.
Domestic leading industrial control embedded computer platform system, full computer win7 system operating platform, integrated software testing, and equipped with cable fault testing software
Leading domestic use of 12.1in large-screen touch system, touch mouse dual control, high-bright screen display, adapt to outdoor sunlight, lithium battery power supply, convenient field test. Engineering aluminum alloy chassis, strong stability against shock and moisture
Adopting the latest USB communication interface, the acquisition signal is stable. The host can automatically select the lowest sampling frequency of 3.125MHz and up to 250MHz,total 8 kinds of frequency sampling . The adaptive pulse width can meet the test requirements of different length cables, reduce the rough measurement error and improve the test Precision.
The software realizes the low-voltage pulse and multi-pulse method automatic identification search, the waveform fault inflection point automatic card position, the fault distance instrument automatically reads and displays, the same screen three areas display waveform, the same screen randomly displays ten low-voltage pulse waveforms for selection, At the same time, automatic and artificial processing modes are realized, which enables double card position operation on the waveform, and the double cursor movement can be accurate to 0.15 meters, which improves the rough measurement accuracy and reduces the waveform error.
Unique multi-pulse generator design, three methods can be completed without reversing the field, and one discharge can obtain ten low-voltage short-circuit pulse waveforms, which greatly reduces the interference of large oscillations, and the multi-pulse generator is small in size. With a weight of only 5KG, it is truly lightweight
The host supports the host's own WIFI receiving function. The dedicated 3G software can realize the expert remote real-time testing technology service at any time. The expert remotely controls the user host. The business technology is equipped with the mobile phone Android version test software, providing users with on-site testing, timely
