Description

Известны устройства дл  дифференцировани  напр жений посредством С-фильтров и усилителей посто нного тока. Известны также дифференцирующие устройства, состо щие из электродвигател , св занного с измерительной схемой и привод щего в движение движок уравновешивающего реохорда.Devices for differentiating voltages with C-filters and direct current amplifiers are known. Differentiating devices are also known, consisting of an electric motor associated with a measuring circuit and setting in motion the balancer of the reichord.

Описываемое дифференцирующее пиковое устройство отличаетс  от известных наличием электромагнитной муфты,  корь которой св зан с водилом приращений. На том же валу свободно вращаетс  водило максимума. Это позвол ет построить простой и надежный прибор дл  определени  прохождени  через максимум дифференциальной кривой The differentiating peak device described is distinguished from the known ones by the presence of an electromagnetic clutch, the measles of which is associated with the increment carrier. The carrier of the maximum freely rotates on the same shaft. This allows you to build a simple and reliable instrument for determining the passage through the maximum of a differential curve.

где С - F(t) - параметр, ступенчато измен ющийс  во времени.where C is F (t) is a stepwise variable parameter.

Конструкци  устройства приведена на чертеже.The design of the device is shown in the drawing.

Электродвигатель /, св занный с измерительной схемой, приводит в движение движок уравновещивающего реохорда 2. На валу 3, св занном с движком реохорда 2, насажена электромагнитна  муфта 4. Якорь муфты св зан с контактным водилом 5 приращений, которое свободно насажено на вал и возвращаетс  в исходное положение с помощью пружины 6 при отсутствии сцеплени  с муфтой 4. На том JKC валу свободно вращаетс  контактное водило 7 максимума, которое может занимать на валу любое положение. При повороте движка реохорда 2 электромагнитна  муфта 4 включаетс  и поворачивает водило 5 на угол О, равный углу поворота движка реохорда- Угол oi пропорционален измер емой э.д.с. Водило 5 передвигает водило 7 максимума на тот же угол ai. При уравновещивании схемы муфта 4 выключаетс , водило 5 возвращаетс  в исходное положение, а водило 7The electric motor / associated with the measuring circuit drives the balancing drive of the rail 2 on the shaft 3. Electromagnetic coupling 4 is mounted on the shaft 3 connected to the rail 2, which is freely mounted on the shaft and returns to the initial position by means of the spring 6 in the absence of coupling with the coupling 4. On that JKC shaft, the contact carrier 7 of the maximum, which can occupy any position on the shaft, rotates freely. When the rotor 2 is rotated, the electromagnetic coupling 4 turns on and rotates the carrier 5 by the angle O equal to the angle of rotation of the reichord engine- The angle oi is proportional to the measured emf. The carrier 5 moves the carrier 7 maximums to the same angle ai. When balancing the circuit, the clutch 4 is turned off, the carrier 5 returns to its original position, and the carrier 7
