Description

фратора 6, соответствующий временному интервалу работы пусковой обмотки 2.fraction 6, corresponding to the time interval of the start winding 2.

При превышении допустимого времени запуска на выходе схемы сравнени  S вырабатываетс  сигнал, который поступает на блок управлени  10. Врем  запуска электродвигател  5 контролируетс  на цифровом индикаторе 7, фиксирующем сигнал с дешифратора 6. Оценка работоспособности электродвигател  обеспечиваетс  по току рабочей обмотки 12 блоком контрол  13, электрически св занным с блоком управлени  10. При превышении заданного уровн  сигнала, соответствующему конкретному типоразмеру холодильного агрегата, с резистора 11 поступает сигнал в блок управлени  10 с последующей передачей его в блок контрол  13.When the allowable starting time is exceeded, the output of the comparison circuit S produces a signal which is fed to the control unit 10. The starting time of the electric motor 5 is monitored on the digital indicator 7, which fixes the signal from the decoder 6. The operating winding of the control unit 12 is electrically evaluated associated with the control unit 10. When the preset signal level corresponding to a specific size of the refrigeration unit is exceeded, a signal is received from the resistor 11 control 10 with its subsequent transfer to the control unit 13.

Наличие в устройстве указанных элемеитов и соединение их по предложенной схеме позвол ет повысить надежность контрол  холодильных агрегатов за счет комплексной оценки их работоспособности.The presence of these elements in the device and their combination according to the proposed scheme makes it possible to increase the reliability of control of refrigeration units due to a comprehensive assessment of their performance.
