Description

the coils on the holes x 5 are connected according to, and the turns on the hole 8 are opposite. The number of Wits in the output winding, located on the hole 8, is 9 times greater than the number of turns in each of the 8 poles.

The bias current iii, the monitored current, is created in each hole of 8 ppm, directed opposite to each other. Under the action of the current in the winding 3, the entire core and is magnetized | IO clock.

The current in the winding of the 2G1 switch disconnects iotaok in the core clockwise. The interaction of monitored currents And bias current IB of each information from / version 5 directs this change in flow to either the internal or external vegetation holes.

The device works in two cycles. In iRaV clock cycle, the winding of the Mesh 4 through the switch 6, the winding section 9 of the Smegzeni winding is connected to the source of the minimum current of 12, which is in the & and lower and controlled sitnal / in. In this case, if all the monitored currents exceed a given level, the magnetic current changes only in those branches of information holes that do not have turns of the output winding 7. The absence of a voltage pulse on the output winding indicates that the monitored devices are idle.

In the second cycle, the bias winding 4 through the switch 6 and the winding section 10 is connected to the maximum current source 13, which is equal to the upper limit of the monitored signals. If none of the monitored currents exceeds the upper limit, the magnetic flux changes only in those branches of the information holes, on which the turns of the output winding are applied. Since all turns of the output winding on the information holes 8 are included according to, and part of it is located on the hole 8, which has nine times more turns, including a counter, and in this case, no pulse output winding voltage that is also connected | IdetelsT | exists serviceability controlled devices.

If one or more of the monitored currents are less than the lower limit, then in the first cycle in the corresponding holes 8 the magnetic flux changes in the zones with the output winding 7, and a pulse appears on the output of the sensor: on control | wet signals.

If one or more of the monitored tracks and the upper limit are exceeded, then in the one-step cycle in the corresponding holes 8 the magnetic note changes in the branches without the output cover 7. As in the second cycle on the output winding of the information hole b, due to the bias current, always; , the emf is shown, then the 1 OUTPUT winding appears and: :: pulse 1: rotary polarity.

Consequently, only in the case when all the monitored currents are within the specified tolerances, there is no signal on the output winding. In the course of at least one signal, beyond the tolerance on the output winding, an irregularity signal appears, from which it is possible to judge the sign of deflection.
