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.

Таким образом, эффективность предлагаемого способа заключаетс  в возможности определени  вида дефекта и повышении эффективности восстановительного ремонта электрических преобразователей. Следует отметить также возможность локализации и определени  вида дефекта в преобразовател х, имеюших внешний металлический бандаж, что принципиально невозможно в способах, использующих измерение внешнего электромагнитного пол  преобразовател . л- /6666 Формула изобретени  Способ неразрушаюшего контрол  электроакустических преобразователей по авт. св. N 592О27, отличающийс  тем, что, с целью расширени J функциональных возможностей способа, после локализации дефекта производ т электрическое отключение поврежденной 66 секции преобразовател , и по характеру изменени  термограммы в зоне повышен него тепловьшелени  определ ют вид дефекта . Источники информации, прин тые во внимание при экспертизе 1. Авторское свипетельство СССР № 592О27, кл. Н О4 R 29/ОО, 1976.Thus, the effectiveness of the proposed method lies in the possibility of determining the type of defect and increasing the efficiency of the repair of electrical converters. It should also be noted the possibility of localizing and determining the type of defect in converters that have an external metal band, which is fundamentally impossible in the methods that use the measurement of the external electromagnetic field of the converter. L- / 6666 The invention of the method of non-destructive control of electroacoustic transducers according to ed. St. N 592О27, characterized in that, in order to expand the J functionality of the method, after the defect is localized, the damaged 66 section of the converter is electrically disconnected, and the type of the thermogram in the area of increased thermal dispersion determines the type of defect.
