Изобретение относитс к контрольно-измерительной технике, в частности к контролю величины сопротивлени контактных соединений, и может быть использовано при организации контрол параметров реле.The invention relates to instrumentation engineering, in particular, to monitoring the magnitude of the resistance of contact connections, and can be used in organizing the monitoring of relay parameters.
Известно устройство дл контрол и измерени сопротивлени контактов реле при низких уровн х нагрузки, содержащее источник питани , шунт, к кб торому черезсопротивление нагрузки присоедин ютс контролируемые контакты , осциллограф, делитель напр жени и коммутатор D JA device for monitoring and measuring the resistance of the contacts of a relay at low load levels is known, which contains a power source, a shunt, and monitored contacts, an oscilloscope, a voltage divider and a switch D J are connected through a load resistance.
Недостатком известного устройства вл етс недостаточна точностьконтрол .A disadvantage of the known device is insufficient accuracy of the control.
Наиболее близким к предлагаемому вл eтd устройство дл контрол сопротивлени контактной пары, содержащее источник тока, нагрузочный резистор , пороговый чувствительный элемент подключающую колодку с двум изолированными друг от друга контактирующими элементами дл вывода контролируемой контактной пары fz.Closest to the proposed device is a device for controlling the resistance of a contact pair, which contains a current source, a load resistor, a threshold sensing element, a connecting block with two contacting elements isolated from each other for outputting a controlled contact pair fz.
Однако несмотр на то, что устройство обеспечивает высокзгю точность контрол , оно не может обеспечить низкий уровень напр %е1ш на контакте.However, despite the fact that the device provides high precision control, it cannot ensure a low level of voltage at the contact.
Цель изобретени - повышение надежности контрол за счет обеспечени низкого уровн напр жени на контактах в процессе контрол .The purpose of the invention is to increase the reliability of control by providing a low voltage level at the contacts during the control process.
