Description
Известные устройства дл автоматического контрол сопротивлени изол ции емкостей, содержащие узел питани , образцовое сопротивление , схему сравнени и сигнализации, требуют подачи на исследуемую деталь импульсных напр лсений, в св зи с чем процесс измерени усложн етс и занимает длительное врем .The known devices for automatic control of the insulation resistance of the containers, containing the power supply unit, the model resistance, the comparison circuit and the signaling system, require the supply of pulse voltages to the component under test, which makes the measurement process more complicated and takes a long time.
Предлагаемое устройство отличаетс тем, что в цем применен вспомогательный конденсатор, включенный параллельно образцовому сопротивлению измерительной цепи, и опросный нереключатель, подключающий вспомогательный конденсатор ко входу схемы сравнени на врем измерени .The proposed device is characterized in that an auxiliary capacitor, connected in parallel to the sample resistance of the measuring circuit, and a interrogator non-switch, connecting the auxiliary capacitor to the input of the comparison circuit for the measurement time, are used in the cement.
Это отличие позволило значительно ускорить процесс измерени и исключить необходимость подачи на исследуемую деталь импульсных напр жений.This difference allowed us to significantly speed up the measurement process and eliminate the need to supply pulsed stresses to the test piece.
На чертеже приведена принципиальна схема предлагаемого устройства .The drawing shows a schematic diagram of the proposed device.
Контролируема деталь / крепитс в зажимах 2, 3 держател и подключаетс под посто нное стабилизированное напр ичение. В это врем вспомогательный конденсатор 4 при помощи переключател 5, установленного в положение а, подключаетс к образцовому сопротивлению 6. В течение некоторого времени, достаточного дл окончани переходных процессов в измерительной цепи, производитс выдержка контролируемой детали под напр жением. При этом напр жение на обкладках конденсатора 4 будет определ тьс величинами сопротивлений детали 1 и сопротивлени 6.The item to be inspected / is fastened in the clips 2, 3 of the holder and is connected under a constant stabilized voltage. At this time, the auxiliary capacitor 4 is connected to the exemplary resistance 6 by means of the switch 5 set to position a for a sufficient time to terminate the transients in the measuring circuit, the controlled part is kept under voltage. In this case, the voltage on the plates of the capacitor 4 will be determined by the values of the resistances of the part 1 and the resistance 6.
После этого переключатель 5 переводитс в положение б и вспомогательный конденсатор 4 подключаетс к усилителю 7, на входе которого по вл етс сигнал с амплитудой обратно пропорциональной величине сопротивлени контролируемой детали 7.After that, the switch 5 is switched to the position b and the auxiliary capacitor 4 is connected to the amplifier 7, at the input of which a signal with an amplitude inversely proportional to the resistance value of the test piece 7 appears.
