Изобретение относитс к контролю качества секционированных преобразователей .This invention relates to quality control of partitioned transducers.
По основному авт. св. № 592О27 известен способ неразрушающего контрол электроакустических преобразователей lAccording to the main author. St. No. 592О27 a method of non-destructive testing of electroacoustic transducers is known l
Однако известным способом невозможно определить вид повреждени , а именно нельз отличить повреждени электроизо- л ции и электрического монтажа секционированных пьезокерамических преобразователей от неэлектрических повреждений (например, механических повреждений пье.зокерамического активного элемента). Определение вида повреждени необходимо дл определени ремонтных операций. В случае механических повреждений трё-« буютс операции замены поврежденных секций. В случае электрических повреждений требуетс исправление монтажа.However, it is not possible to determine the type of damage in a known manner, namely, it is impossible to distinguish between damage to electrical insulation and electrical installation of partitioned piezoceramic transducers from non-electrical damage (for example, mechanical damage to a piezoelectric active element). Determining the type of damage is necessary to determine repair operations. In case of mechanical damage, three- “replace the damaged sections. In the case of electrical damage, a wiring repair is required.
Цель изобретени - расширение функциональных возможностей способа.The purpose of the invention is to expand the functionality of the method.
Дл этого после локализации дефекта производ т электрическое отключениеFor this, after the defect is localized, an electrical disconnection is performed.
поврежденной секции преобразо1вател , и по характеру изменени термограммы в зоне повышенного тепловыделени определ ют вид дефекта.the damaged section of the converter, and the nature of the thermogram in the area of high heat generation determine the type of defect.
По характеру изменени термограммы даетс заключение: дефект электрического или неэлектрического происхождени (трещин, непроклей и др.). Если п тно продолжает развиватьс , то оно соответ ствует неэлектрическому виду дефекта. Если п тно пропадает, вид дефекта - электрический .By the nature of the thermogram change, a conclusion is drawn: a defect of electrical or non-electrical origin (cracks, non-glue, etc.). If the spot continues to develop, then it corresponds to the non-electric type of defect. If the patch disappears, the type of defect is electric.
