За влено 26 окт бр 196 г. за Л .749744/26-10 в Комитет по делам изобретений и открытий при Совете Министров СССРIt was filed on October 26, 196, for L. 749744 / 26-10, to the Committee on Inventions and Discoveries under the Council of Ministers of the USSR
Опубликовано в «Бюллетене изобретении № 17 за 1962 г.Published in Inventory Bulletin No. 17, 1962.
Основное авт. св. № 113189 от 4 июл 1957 г. на нм Б. М. ШлимовичThe main author. St. No. 113189 dated July 4, 1957 at nm B. M. Shlimovich
Предлагаемое устройство дл изменени пределов Измерени электрических ИзмерИтельных приборов представл ет собой развитие дальнейшее усовершенствование изобретени по авт. св. № 113189.The proposed device for changing the limits of the Measurement of electrical Measuring devices represents a further development of the invention according to the author. St. No. 113189.
Основное авт. св. Aig 113189 выдано на устройство дл изменени пределов измерени электрических измерительных приборов, в котором изменение пределов производ т при помоши двух фотореле, установленных у концов шкалы и уп|рав.л емых указателем, и шагового искател , которым управл ет фотореле.The main author. St. Aig 113189 is issued to a device for changing the measurement limits of electrical measuring instruments, in which the limits are changed using two photo relays installed at the ends of the scale and set up equal to the pointer, and a step finder controlled by the photo relays.
.Недостатком устройства по авт. св. № 113189 вл етс отсутствие возможности переключени прибора при большом интервале изменени тока (напр жени ) в том случае, если это изменение произошло достаточно быстро. Например, нельз произвести переключение с первого предела на третий.The disadvantage of the device on the author. St. No. 113189 is the inability to switch the device with a large current (voltage) interval in the event that this change occurred fairly quickly. For example, it is not possible to switch from the first limit to the third.
В предлагаемом уст.ройст.ве использованием тиратрона с холодным катодо.м, цепочки RC и шагового искател , управл емого через тиратрон , достигаетс автоматическа установка необходимого предела измерени при большом увеличении измер емой величины.In the proposed installation, using a cold cathode tiratron, an RC chain and a step finder controlled via a tiratron, an automatic setting of the required measurement limit is achieved with a large increase in the measured value.
На чертеже изображена -схема предлагаемого устройства, содержашего датчики Д и До, представл ющие собой фотореле, срабатывающие при зате.мнении чувствительного элемента.The drawing shows a schematic diagram of the proposed device, containing the sensors D and Do, which are photo relays that are triggered when the sensitive element is imaged.
Основным элементом устройства вл етс шаговый искатель /, имеющий три контактных пол /, // и ///. Шаговый искатель п риводитс в движение либо импульсами, либо через цепь, управл емую датчиком Д, либо цепью самохода, состо щей из управл ющего контакта lIJi и контакта 2 самохода.The main element of the device is a step finder / having three contact fields /, // and ///. The step finder is driven either by pulses or through a circuit controlled by sensor D or by a self-moving circuit consisting of an lIJi control contact and a self-driving contact 2.
Когда измер ема величина зн.ачительно увеличитс , и экран из фольги, укрепленный (на стрелке 3 измерительного прибора, перекроет световой поток, поступающий на фотосопротивление ФСК-1, тогда сопротивление ФСК-} возрастет и через сопротивление JR зар дитс еми М. С. БелицкойWhen the measured value increases significantly, and the foil shield is reinforced (on arrow 3 of the measuring device, the luminous flux going to the photoresistance of FSK-1 will be blocked, then the resistance of the PSK-} will increase and through the resistance JR will charge M.
