Partial discharge phenomenon of electrical equipment on the electrical equipment itself and the power grid will have different degrees of impact, serious and even lead to equipment scrapped and the collapse of the power grid, so the early local discharge monitoring of electrical equipment, accurately grasp the operating conditions of the equipment, timely and effective elimination of equipment faults that exist in the hidden danger of equipment failures nipped in the bud, to ensure the safety of the equipment and the power grid itself plays a crucial role. Role. There are many methods to detect the local discharge of electrical equipment, such as: pulse current method, DGA method, ultrasonic detection method, RIV method, light measurement method, radio frequency detection method and chemical methods. Various detection methods have their own strengths, but compared to the ultrasonic detection method is simple and easy to use, very suitable for daily equipment point inspection, real-time grasp of the operating conditions of electrical equipment. Common electrical equipment local discharge faults will generally have: corona, arc and electric traces. Corona and the initial traces will not produce heat, and environmental high temperature will also mask these phenomena, with the daily infrared camera can not be detected, but it will produce ultrasonic signals, with ultrasonic local discharge inspector can be detected at a distance. Arc and serious electric traces in the generation of ultrasonic waves will also produce high heat, so with infrared and ultrasonic methods can be tested; but when the discharge occurs inside the equipment, the infrared method can not be detected, with ultrasonic discharge inspector in the surface of the electrical equipment or the bonding surface of the test can be carried out.
Ultrasonic partial discharge inspector is through the collection of abnormal ultrasonic signals and software analysis of power lines to diagnose power line fault detection device. This device is in the state of non-power state to achieve the judgement of the location of hidden faults and fault types. The device through the ultrasonic detector (ultrasonic sensor) to collect ultrasonic abnormal signals, transmitted to the host, and through the host built-in analysis software to accurately diagnose the type and severity of hidden faults, and converted into audible sound signals and waveforms, to help inspectors accurately find the line faults hidden, to prevent the occurrence of malignant faults, to avoid unnecessary blackouts, improve the reliability of the power supply, and at the same time also Improve the work efficiency of inspectors and reduce the labour intensity of inspectors.
