The names and uses are different. The following is a small series to show you the performance characteristics of some commonly used cable fault testers. : Application and characteristics of cable fault tester At present, there are too many varieties of high-voltage cable fault test in domestic cable fault tester manufacturers. The names and uses are different. The following is a small series to show you the performance of some commonly used cable fault testers. Features: 1. Cable fault detector, suitable for measuring the low resistance, short circuit, open circuit and disconnection of power cables, high frequency coaxial cables, local telephone cables, street lamp cables, and buried wires of various materials with different cross-sections and different media. Line faults, as well as high resistance = tlifS and high resistance flashover faults. It integrates the advantages of similar instruments at home and abroad, beautiful appearance, small size, light weight and easy to carry. It adheres to our company's consistent high-tech, high-precision, and high-quality principles, and raises the level of cable testing to a new level.
The cable fault detector has the characteristics of accurate test, high degree of intelligence, convenient operation, wide adaptability, stable performance, light weight and portability. 2. The live cable identification instrument is used to identify a specific cable to be found in a bundle of cables in the erection, migration, maintenance and troubleshooting of power cables; it has the characteristics of accurate and fast identification of cables, simple operation and wide application range. . It is an indispensable testing instrument in cable construction and maintenance.
The instrument consists of a cable identification transmitter, a cable identification receiver, a transmitting caliper, a receiving caliper and an output signal connecting line. It has high-power current pulse output; on-site receiving signal features are clear, light and flexible, high sensitivity, can effectively suppress on-site power frequency interference; accurate and fast judgment; reliable protection circuit, not afraid of output short circuit; large jaw ф150 is suitable for various cross-sectional areas There is a high-power isolation transformer inside, and the operator does not have any direct electrical contact with the mains. Greatly guaranteed personal safety.
When the live cable is identified, it is not necessary to disconnect the connection between the two ends of each cable and the transformation and distribution equipment. Online identification can be carried out when the cable is live, which improves the efficiency of identification and greatly reduces the direct and indirect damage caused by power outages. economic losses. 3. The street lamp cable fault tester is the latest generation of cable fault locator carefully designed and independently developed by our company. It can quickly test the short circuit, open circuit and ground fault of the street light cable.
After several years of upgrades, the instrument is easier to use and more accurate to test. One-button operation is superior to the cumbersome operation of similar products. As long as you operate it once, you can master it all.
The street light cable fault locator breaks the tradition of using the principle of ignition and discharge to listen to the sound to test cable faults. The instrument does not need ignition and discharge when testing cable faults, neither auxiliary equipment nor power supply (the instrument is powered by batteries), The operation method is very simple, no need to analyze the waveform, and one or two people can easily operate it, which is equivalent to a tool-type instrument. It can be used without training and is the first choice for street light maintenance units. 4. The multi-pulse cable fault tester adopts the arc reflection (multi-pulse) technology of the highest level in the world. All high-resistance fault test waveforms are presented as simple low-voltage pulse waveforms, and it is easy and pleasant to judge the fault distance.
5. Touch screen cable fault tester, the host uses an embedded computer for measurement control and data processing, the entire operation is carried out under the Windows interface, the 10-inch touch screen display area is large, the measurement waveform is intuitive, the operation is convenient, the universal USB interface, and the hard disk can be used. A large amount of measurement data is stored, and the measurement results can be stored and printed on-site, and can also be printed off-site, and the data will never be lost. Because the embedded computer is used, the reliability of the system is improved, the maintenance is accurate, comparative analysis, the test accuracy is improved, and the error is reduced. 6. The cable fault tester consists of a test host, a path signal generator, a path signal receiver and a locator.
The fault test host includes an integrated computer, low-voltage pulse generation and data processing, which is used to test the distance of the fault, and can also be used to measure the length of the cable and the propagation speed of radio waves in the cable. The path signal generator generates an intermittent sine wave signal with a frequency of 30KHz and a maximum amplitude of 30V, which is used to find and measure the cable path. The path signal receiver is used to receive the path signal, which is used to find the direction of the cable and estimate the depth of the cable buried.
The locator is used for precise location of the fault point. Cable fault tester manufacturer Shenzhen Noyafa Electronic Technology Co., Ltd.
