| Detailed Product Description: | ULTRAPROBE ultrasonic detector is an ultrasonic receiver analysis and processing apparatus, the principle is similar to the radio, the difference between life detector receiver is generated by the production of ultrasound, and then through the piezoelectric principle of the ultrasonic signals into a current through the internal processor into the audio signal. ULTRAPROBE 2000 Analog Ultrasonic Detection System electrical power has three basic power problems will be detected: 1. Arc: Electricity flows through the space causes the arc occurred, lightning is a good example. 2. Corona: the voltage of the electrical conductor, such as antenna or high voltage transmission line, when more than the threshold value, the ionization of the surrounding air begins to form a blue or purple glow .3. Power Streak: commonly referred to as' small arc ', through the damaged insulation lines. Although theoretically can be used for ultrasonic testing of low, medium and high voltage systems, but most of the applications are often in the middle and high voltage systems, when the power in the high voltage line power to escape or when it is connected across the gap position, it disturbs the surrounding air molecules and produce ultrasound. Usually the sound will be like the sound of crackling or frying sound as perceived; in other cases, often like a buzzing sound. Main applications include: insulators, cables, switches, bus. Relays, contactors, connection boxes. In the substation, you can test components such as insulators, transformers and insulating covers. Ultrasonic testing is often used for the assessment of the voltage over 2000 volts, especially in enclosed switchgear. Is particularly useful in the identification in a closed switching device tracking. The frequency of tracking can be prepared much more than identify the serious failures infrared frequency. As suggested, for the closure of switch equipment, the two tests are used. Note: When testing electrical equipment, follow all of your factory or the company's safety procedures. When in doubt, ask your supervisor. Do not touch the running of electrical equipment and systems. Detection method is similar to arc and corona leak detection procedures. The difference is not a shock to hear the sound, but the crack or hum. For example, as trying to find the radio / TV interference or in the source substation, radio / television stations or interference in substations, the general interference zone can take advantage of such a transistor radio or a wide-wave interference locator to find the total detector. Once the basic area is found, the scanning module is the basic area scan. If the signal is too strong so that the instrument can not be tracked to reduce the sensitivity until the loudest point is found, determine the presence or absence is relatively simple. By comparing the sound level of sound quality of them, the problem often have very different sound. Low voltage systems, for the bus to find a quick scan often loose connections. Check the junction box to expose the arc formation. Check the overhead lines from the ground, if the signal is not very strong, you can use an ultrasonic wave concentrator U |
