Many power technicians don't know much about the cable fault tester, so this article will introduce the cable fault tester.
Cable fault tester (also known as intelligent cable fault tester) is a comprehensive cable fault detection instrument. It can test the high resistance flashover fault, high and low resistance grounding, short circuit, cable disconnection, poor contact and other faults of the cable. If equipped with the acoustic method pointing instrument, it can accurately determine the precise position of the fault point. It is especially suitable for testing power cables and communication cables of various models and different levels of voltage. It adopts a variety of fault detection methods, applies contemporary advanced electronic technology achievements and devices, adopts computer technology and special electronic technology, and combines the successful experience of long-term development of cable tester. It is a new product with high technology, intelligence and full functions.
ZC-700A cable fault tester is a new product developed and designed by our company. This product integrates cable fault test and path signal source, making the on-site test more convenient and simple. This type of cable fault tester has small volume, complete functions, simple operation and built-in low battery alarm. It is the main intelligent cable fault tester in our cable fault tester series.ZC-700Acable fault tester consists of three parts: flash test, tracing and positioning.
ZC-700A cable fault tester can be used to detect low resistance, high resistance, short circuit, open circuit, leakage fault and flashover fault of various cables, and can accurately detect the location of fault point, cable length and buried path of underground cables. It has the characteristics of accurate test, high degree of intelligence, wide adaptability, stable performance, light and portable. The instrument adopts Chinese character system, high-definition display and friendly interface.
Cable tracing and fault location are composed of Pathfinder, pointing instrument, t-probe, A-frame, earpiece, etc. This instrument is a special instrument for cable fault location test. It is applicable to all kinds of cables with metal conductors (wire pair, protective layer and shielding layer). Its main functions are the positioning test of poor insulation points to the ground, the detection of cable path and the test of cable buried depth.
Characteristics of ZC-700A cable fault tester:
1. Cable fault tester (flash tester)
(1) Wide range of application: it is used to measure the high and low resistance, short circuit, open circuit, disconnection, high resistance leakage and high resistance flashover faults of various power cables with different sections and media, high frequency coaxial cables, local telephone cables and more than two evenly laid buried wires. It can also be used to measure the length of the cable and the propagation speed of electric waves in the cable;
(2) Easy to carry: the host is powered by lithium battery, lightweight, easy to carry, convenient for field test and mine cable test;
(3) Friendly man-machine interface: large screen 320 is adopted × 240 dot matrix Chinese character graphic interface, high brightness, clear and beautiful graphics, simple operation and strong anti-interference;
(4) Safe and reliable: a new type of current sampler is adopted, which is a brand-new sampling method. It has the characteristics of simple wiring, intuitive waveform, easy analysis, complete isolation from high voltage and safety to the host and operators;
(5) High quality: all key components are imported components to ensure the * degree of test results;
(6) Exquisite appearance: the solid and wear-resistant materials are adopted to make the overall texture and service life of the instrument longer or relative distance.
2. Speed function of Pathfinder and pointing instrument
(1) High receiving sensitivity: special manufacturing process is adopted, the transmission distance is increased, and the instrument can still receive signals clearly;
(2) Low static drift: the core components are imported components with reliable performance;
(3) High positioning accuracy: quartz crystal oscillator and high-speed signal processing chip are used for signal sampling and processing to ensure accurate and reliable positioning accuracy;
(4) Strong anti-interference ability: under severe interference conditions, the instrument can still ensure good performance and stable operation;
(5) Easy to carry: built in rechargeable battery power supply, suitable for various occasions.
ZC-700A cable fault tester is also a new generation of portable cable fault tester carefully designed and manufactured by our company according to user requirements and considering on-site use. It adheres to our consistent purpose of high technology, high precision and high quality, and improves the cable testing level to a new level.
