Изобретение относитс к электрическим машинам и может найти применение в специализированных приборах диагностировани дл безразборного контрол технического состо ни электродвигателей непосредственно на объекте, например на борту самолета.The invention relates to electric machines and can be used in specialized diagnostic instruments for indiscriminately monitoring the technical condition of electric motors directly at the facility, for example, on board an aircraft.
Известны устройства контрол электрических машин, содержащие датчик коммутационных пульсаций напр жени , фильтр и индикатор l .Control devices for electrical machines are known, which include a voltage switching pulsation sensor, a filter, and an indicator l.
Недостатками подобных устройств вл ютс ограниченна область применени и мала достоверность диагноза, обусловленна зависимостью контроли- ,5 руемого параметра от различных факторов .The disadvantages of such devices are the limited scope and low accuracy of the diagnosis, due to the dependence of the controlled parameter on various factors.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс устройство, сО7о держащее Датчик коммутационных пульсаций напр жени , блок измерени отношени пикового и средневыпр мленного значений пульсаций напр жени .The closest in technical essence and the achieved result to the invention is the device, which holds the Sensor of switching voltage ripple, the measuring unit of the ratio of peak and average value of voltage ripple.
индикатор, датчик частоты вращени , схему сравнени , генератор опорной частоты и блок индикации отклонени частоты вращени от опорной 2.the indicator, the rotational speed sensor, the comparison circuit, the reference frequency generator, and the rotation speed deviation indication unit from the reference 2.
Недостатком известного устройства вл етс низка точность контрол коэффициента усреднени пульсаций напр жени (отношение пикового значени к средневыпр мленному), используемого в качестве диагностического параметра, что приводит к снижению достоверности диагноза. В частности, при использовании известного устройства в переносных диагностических приборах.(которые эксплуатируютс в температурном диапазоне -60 - +60 С) невозможно контролировать коэффициент усреднени пульсаций напр жени с погрешностью менее .Целью изобретени вл етс повышение точности контрол .A disadvantage of the known device is the low accuracy of the control of the averaging coefficient of the voltage pulsations (the ratio of the peak value to the average), which is used as a diagnostic parameter, which leads to a decrease in the reliability of the diagnosis. In particular, when using a known device in portable diagnostic devices (which operate in a temperature range of -60 to +60 ° C), it is impossible to control the coefficient of averaging voltage pulsations with an error of less than. The purpose of the invention is to improve the accuracy of control.
