The TKDL-IV cable fault tester is a special system equipment for power cable fault testing developed and produced by our company under the opportunity of the rapid progress of the power industry, according to industry development and market demand.
It is mainly used to test open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults of power cables, as well as accurate measurement of open circuit and short circuit faults of coaxial communication cables and local telephone cables.
Test; it can also measure the electric wave speed, measure the cable length, etc., and establish cable files for daily maintenance and management.
Cable fault location finder
The cable fault distance finder adopts high-level time domain reflectometry (TDR) technology, and the fault waveform is automatically judged, simple and clear, and convenient and pleasant to use; the whole machine adopts an industrial control plastic case, which is small and exquisite.
It is easy to carry; the man-machine interface is friendly, even if the non-professionals operate, you can still get familiar with and use it quickly, and complete the cable fault test work efficiently and accurately.
Acousto-magnetic digital display synchronous fixed-point instrument
This product is used for fast and accurate positioning of buried fault points and accurate detection of cable buried paths and buried depths. Specially structured acoustic vibration sensors and low-noise special devices are used as preamplifiers.
Large, greatly improving the sensitivity of the instrument's fixed-point and path detection. In terms of signal processing technology, the distance between the fault point and the sensor probe is digitally displayed, which greatly eliminates the blindness at fixed points.
For the faulty cable in the overhead, when the point was fixed, the vibration of the whole cable made any pointing instrument helpless and unable to determine the specific location of the enclosed fault. Now, just connect the sensor probe of this instrument
Touching the faulty cable or nearby cables, the fault distance can be accurately displayed, and the fault location can be determined quickly and effortlessly. The power frequency adaptive cancellation theory and the high-Q power frequency notch technology greatly enhance the
In the strong power frequency electric field environment, the suppression and anti-interference ability of the 50Hz power frequency signal reduces the blind spot of the fixed point. In the function of the instrument, the use of sound and electricity synchronous receiving and display technology effectively overcomes the fixed-point site
Difficulty in spotting caused by environmental noise interference. In particular, the digital display of the fault distance eliminates the need for operators to analyze and judge complex waveforms, and to a considerable extent replaces the rough distance measurement function of the flash tester.
can. For a faulty cable of hundreds of meters long, it is generally possible to implement fixed point without rough measurement, which truly achieves high efficiency, speed and accuracy. Use 15KHz amplitude modulation electromagnetic wave and amplitude detection technology as the path
Detecting and measuring the depth of cable burying avoids the interference of the TV line frequency on the pointing instrument when the original constant amplitude 15KHz signal source is used. The operation is extremely simple, just turn on the power switch, and there is no need to change gears and function selection.
select. The structure is compact, small, modular, easy to carry and maintain, and powerful.
Cable path finding signal transmitter
When the sine wave signal output by this product is added to the cable, there is an electromagnetic field around the cable. A magnetoelectric sensor (induction coil) is used to convert the electromagnetic wave into an electric signal, which is put through an amplifier.
It is converted into a sound wave signal by a buzzer or earphone, and the change of the signal can be reflected by the meter. When the coil is directly above the cable and perpendicular to the ground, the induced electromotive force of the coil is the smallest;
When the coil is perpendicular to the ground and deviates from the cable a certain distance, the lines of magnetic force passing through the coil increase, and the induced electromotive force of the coil increases. This principle can be used to detect the path of the cable.
YD series high voltage test power supply
YD series high voltage test power supply is suitable for power supply enterprises, large factories, metallurgy, power plants, railway transportation, post and telecommunications departments, scientific research institutions, etc. It is a necessary equipment for power inspection and maintenance. The set
The equipment is composed of three parts: operation box, test transformer, and capacitor. It can conduct insulation strength test under power frequency or DC high voltage for various high voltage electrical equipment, electrical components, and insulation materials.
Cable and other fault detection provide high-voltage signal power.
