Abstract
Способ диагностики и контроля замыкания листов активной стали сердечников электрических машин путем сканирования, отличающийся тем, что диагностика сердечника производится путем лазерного сканирования в диапазоне длинных волн 300-1500 нм, контроль состояния листов электротехнической стали осуществляется с помощью анализатора колебаний интенсивности рассеянного в сердечнике лазерного излучения, диагностическим признаком является изменение амплитуды колебаний интенсивности излучения, рассеянного в диагностируемом участке сердечника, контроль повреждения состояния листов электротехнической стали осуществляется путем измерения амплитуды колебаний интенсивности излучения, рассеянного в сердечнике, а диагностика степени повреждения состояния листов электротехнической стали осуществляется путем сравнительного анализа результата полученной погрешности измерения амплитуды колебаний интенсивности излучения, рассеянного в исправном сердечнике, и амплитуды колебаний интенсивности излучения, рассеянного в испытуемом сердечнике.A method for the diagnosis and control of the closure of sheets of active steel in the cores of electric machines by scanning, characterized in that the core is diagnosed by laser scanning in the long wavelength range of 300-1500 nm, the state of the sheets of electrical steel is monitored using an intensity oscillation analyzer of the laser radiation scattered in the core, a diagnostic sign is a change in the amplitude of fluctuations in the intensity of radiation scattered in the diagnosed area of the core damage state control of sheets of electrical steel is controlled by measuring the amplitude of fluctuations in the intensity of radiation scattered in the core, and the diagnosis of the degree of damage to the state of sheets of electrical steel is carried out by comparative analysis of the result of an error in measuring the amplitude of fluctuations of radiation intensity scattered in a working core, and the amplitude of fluctuations in radiation intensity scattered in the test core.
