Description

l1: iMO (nTi.) ic devices, C1 /) slkg1 which () iix has a small torque moment, can serve to regulate the maple and devices under the condition of using “priiodimetgm i” current sources of: ())) depending on the position of the arrow of the measuring iipiiCopa ia regulating device. In response: e FIG. f depicts the scheme proposed by the arrangement; FIG. 1 - fall of this cxef,: i) i; FIG. 2 - changing the specified device; FIG. 3 shows a slightly different form of the dusting of the device, izore6; from the bottom in FIG. 2

To regulate (Sri. 1), use J of some device, some KOTOpoii equals a normal C) with a controlled variable, i with an arrow on one side 1: about 1.7 and plate 2, 3, and on the other ciopDHi. contact1) 1e plates, 5, A clamp b is located above the cr () tree, which can rotate on hinges 7 and is held in a raised position: blue 1: ru; by another or any other opposing force (not indicated on cherkalo). As the excitement occurs, the electromagnet 8 cd1111, Homutik C is attracted downward and exerts pressure on the arrow 1. The electromagnet 8 is excitably: given by current source 9 each time two sliding contacts 10 are connected instead of by means of a conductor of a part of the contact disk 11. If the regulated value deviates from its established value, the arrow will occupy the one shown in FIG. 1 position above pins 2 and 3. When the electromagnet 8 is energized, arrow 1 is pressed by clamp 6 to pins 2 and 3, so that an electrical circuit is formed from current source 12 through contact plate 3, arrow 1, contact plate 2, front 13 k electrically controlled motor 14 for adjustment and back to the current source 12. The motor serving for regulation rotates until the current circuit of electromagnet 8 is closed when POM1II of the contact disk 11 and the adjustable device, for example, a resistor in the excitation circuit, adheres engine or dynamo or steam valve, plumbing, etc. If the regulated value decreases, the TQ arrow 1 will rise above the contact of the motor 4 and 5 and connect the engine 14 to the current source 15, with

the aid of which he is brought into reverse rotational rotation and thus pusts a control device in the other direction.

In addition, on the contact disk 11, the third sliding contact 16, electrically connected to the electromagnet 8 by means of the contact strips 17 or 18. If the controlled value zpa deviates markedly from the normal

meaning, YO arrow; 1 departs from its average position so that it comes over coitStates 17 or15: And connect them, thanks to which the excitation circuit of electromagnet 8 is in the closed position and for a longer time that. entails compliance: stpsino more significant shift of the regulatory body.

If for some reason the brakes 6 either brake or the arrow 1 touches one of the contact plates, it may happen that the engine 14 moves the regulator too far to them. In order to avoid this (on the Jijdiwep, if the electric generator is regulated), relay 19 is provided from the transformer current 20, placed in the circuit 21 of an adjustable alternator. As soon as the current in THIS wire exceeds the permissible Atmax limit, the relay 19 will open the switch 22. This will interrupt the current going from the current source 15 to the motor 14 for regulation. Instead of or also in conjunction with the relay 19, the current converter 20 and the switch 22, a decelerating relay can be applied between the regulator and the motor 14 and disconnecting the drive circuit of the digger after a certain period of time. This period of preampi should be chosen, for example, in such a way that the engine 14 will produce a permutation of not more than 10% of the adjustable size. The clock mechanism of the decelerating relay starts after each; when the stroke of the clamp 6, for example, by means of an electromagnet 8, as seen in FIG. 1. The clockwork is made by the worm 50 placed under the electromagnet 8. When the last 1} is excited, the current of the chopper 51 closes

through conductor 13 and remains closed until the delay relay switches off after a certain, predetermined period of time has elapsed.

A more favorable regulation can be achieved if, with a significant deviation of the controlled variable, it is not the duration of individual pulses that increases, but the number of pulses of adjustment per unit of time. Such devices are shown in FIG. 2. Here, the contact disk 11 is provided with two more sliding contacts 25, which close the excitation circuit of the electromagnet 8 only if the contact 26 is closed. This contact is between two electromagnets 27 and 28, the latter being excited when the collar 6 presses the arrow. at 1 to the contact plate 31 or 32. having become excited, the electromagnet 28 closes contact 26, which remains in the closed position and in the event that the current through contacts 31 and 32 is interrupted again. The electromagnet 8, therefore, is twice excited at each revolution of the contact disk 11 and, moreover, prior to pressing the arrow 1 against the contact plate 29, i.e. until the regulated value reaches the required size again. After that, the electromagnet 27 opens the switch 26.,

Instead of the contact roller 11, a bimetallic rod 30 (FIG. 3) can be used, which, when heated using the coil 30, opens the contact, and when it is cooled, closes it again.
