Description

Данное изобретение относитс  к области устройств, служащих дл  устранени  взаимного вли ни  между двум  электрическими цеп ми , подключенными к общему источнику или потребителю электрической энергии переменного напр жени .This invention relates to the field of devices for eliminating the mutual influence between two electrical circuits connected to a common source or consumer of alternating voltage electrical energy.

Известные устройства того же назначени  выполнены либо в виде уравновешенного моста, образованного активными или, в общем случае , комплексными сопротивлени ми , либо в виде дифференциального трансформатора, вторична  обзуютка которого имеет вывод от средней точки и включена в схему таким образом, что ее половины образуют два плеча уравновешенного моста.The known devices of the same designation are made either in the form of a balanced bridge formed by active or, in general, complex resistances, or in the form of a differential transformer, the secondary of which has a terminal from the midpoint and is included in the circuit in such a way that its halves form two shoulder balanced bridge.

Предлагаемое устройство, в отличие от известных дифференциальных систем, выполнено в виде пьезоэлектрического резонатора с трем  парами электродов. Существенными преимуц.1,ествами описываемого устройства  вл ютс : малые габариты и возможность использовани  частотно-избирательных свойств пьезоэлектрической пластины дл  выделени  требуемой полосы частот.The proposed device, in contrast to the known differential systems, is made in the form of a piezoelectric resonator with three pairs of electrodes. The essential advantages of the device described here are: small size and the possibility of using the frequency-selective properties of the piezoelectric plate to select the desired frequency band.

Схематически устройство изображено на чертеже.Schematically, the device shown in the drawing.

Пьезоэлектрическа  пластина / помещена между трем  парами электродов: 2-2, 3-3 и 4-4. Электроды 2 и 4, расположенные с противоположных концов по обе стороны пластины /, соединены между собой и образуют среднюю точку О дифференциальной системы . Отводы от электродов 3 и 3 образуют входные зажимы аа устройства, а отводы от электродов 2 и 4 служат выходными зажимами бб устройства.A piezoelectric plate / is placed between three pairs of electrodes: 2-2, 3-3 and 4-4. The electrodes 2 and 4, located at opposite ends on either side of the plate /, are interconnected and form the midpoint O of the differential system. The taps from electrodes 3 and 3 form the input terminals aa of the device, and taps from electrodes 2 and 4 serve as the output terminals of the device bb.
