Description

technical field [0001] The invention relates to an insulator detection device and a detection method, in particular to a vibrating acoustic wave-based live flaw detection device and method for porcelain post insulators. Background technique [0002] Post insulators are an important component of power plants and substations. They are widely used in power systems and play the role of supporting wires, circuit breakers and high-voltage switches. Porcelain post insulators are the most important components. Fracture accidents have occurred frequently in recent years, seriously affecting the safe and stable operation of the power grid. Preventive detection is the key to reducing fracture accidents. However, the aging and failure of pillar porcelain insulators is a gradual process, and it is not easy to find problems in time. However, if it is not discovered and dealt with in time, it may lead to failure of power equipment, or even sudden power accidents, resulting in huge direct ...
