Устройство относитс  к контрольно-измерительной технике и может быть использовано дл  проверки работоспособности электрического монтажа, в частности электрожгутов.The device relates to a measuring and measuring technique and can be used to check the operability of electrical installation, in particular electrical bundles.

Известны устройства дл  проверки работоспособности электрического монтажа, содержащие блок питани , многоканальные шаговые коммутаторы, неподвижные контакты которых подключены к провер емым цеп м монтажа , и исполнительные реле, в которых вы вление обрывов, перепутываний, замыканий каждой цепи осуществл етс  в два этапа. На первом этапе через шаговый коммутатор входа , провер емую цепь, шаговый коммутатор выхода напр жение подаетс  на сигнальное реле, которое, в случае целостности провер емой цепи и отсутствии перепутывани  ее с другими цеп ми, срабатывает, что свидетельствует о завершении этого этапа.Devices for checking the operability of electrical installation are known, comprising a power supply unit, multichannel stepping switches, the fixed contacts of which are connected to verifiable installation circuits, and executive relays in which the detection of breaks, entanglements, and short circuits of each circuit is carried out in two stages. At the first stage, the voltage is applied to the signal relay through the input step switch, the tested circuit, the output step switch to the signal relay, which, in case of integrity of the circuit being tested and not being tangled with other circuits, is triggered, indicating that this stage is completed.

На втором этапе коммутатор выхода осуществл ет последовательный обход всех остальных цепей, при отсутствии замыкани  между ними и провер емой цепью сигнальное реле не срабатывает.At the second stage, the output switch performs a sequential bypass of all the other circuits; in the absence of a short circuit between them and the circuit being tested, the signal relay does not operate.

Устройства такого типа обладают низкой эксплуатационной надежностью (шаговый коммутатор выхода в процессе проверки совершает количество полных циклов, равное числу провер емых цепей) и малым быстродействием .Devices of this type have low operational reliability (the step-by-step output switch performs the number of complete cycles equal to the number of circuits to be checked) and low speed.

С целью сокращени  времени контрол  и расширени  функциональных возможностей предлагаемое устройство снабжено резисторами , подключенными последовательно к блоку питани , первые выводы резисторов соединены с подвижными контактами одного коммутатора , соответствующие контакты другого коммутатора через обмотки исполнительного реле подключены к вторым выводам этих резисторов .In order to reduce the monitoring time and expand the functionality, the proposed device is equipped with resistors connected in series to the power supply unit, the first terminals of the resistors are connected to the moving contacts of one switch, the corresponding contacts of the other switch are connected via the windings of the executive relay to the second terminals of these resistors.

Поставленна  цель может быть достигнутаThe goal can be achieved

при условии, что выбранные цепи будут сразуprovided the selected chains are immediately

проверены не только на отсутствие обрывов,not only checked for cliffs,

но и на отсутствие замыканий и перепутываНИИ между собой.but also on the absence of closures and confusion between them.

На чертеже показана схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

В предлагаемом устройстве резисторы 1 подключены последовательно к блоку питани  2. Подвижные контакты 3 первого коммутатора 4 подключены к первым выводам резисторов 1, а подвижные контакты 5 второго коммутатора 6 через обмотки исполнительных реле 7 - к вторым выводам резисторов 1. Провер емые цепи 8-11 подключены между неподвижными контактами коммутаторов 4 и 6.In the proposed device, the resistors 1 are connected in series to the power supply 2. The moving contacts 3 of the first switch 4 are connected to the first terminals of the resistors 1, and the moving contacts 5 of the second switch 6 through the windings of the execution relays 7 to the second terminals of the resistors 1. Tested circuits 8-11 connected between the fixed contacts of switches 4 and 6.

Устройство работает следующим образом.The device works as follows.
