Description

The invention relates to the field of electrical engineering and can be used for electrical control and in power systems.

There is an electromechanical device that is part of the "autonomous power supply system" noted in patent No. 2316108, by A. Chasovskaya, dated January 27, 2008. In it, a DC battery is supplied through an automatic trip unit and a rheostat, which can be placed after the release, in the DC motor, with which the shaft of the synchronous generator is rotated. The latter produces an alternating voltage. An automatic trip device connects its first or second input, depending on the magnitude of the voltages at these inputs. However, the operating time is limited due to the need to charge the battery.

It is known an electromechanical device that is part of an autonomous power supply system set forth in patent No. 2396694 of 08/10/2010. In it, in contrast to the aforementioned, the battery is recharged in the absence of its discharge. The device may also include a voltage stabilizer and a block of two automatic releases, which is triggered when the voltage drops below the permissible level. In this case, two outputs of the unit can be connected to two inputs of the battery, and its two inputs are connected respectively to the first and second outputs of the battery recharging device. However, uninterrupted operation of the electric motor is not ensured, since the time of the absence of battery discharge may not be enough to charge it.

Using the proposed device provides uninterrupted operation of the electric motor. This is achieved by introducing a second block of two automatic releases and a second battery, while the first and second outputs of the battery recharging device are connected to the first and second inputs of the second block of two automatic releases having a first and second outputs and a third input, respectively connected to the first and the second inputs of the second battery and with its output, also connected to the second input of the automatic release, the aforementioned first input of which is connected to the third input of the first Lok Automatic two releases.

In figure 1 and in the text the following notation:

1 - rechargeable battery;

2 - automatic release;

3 - rheostat;

4 - a direct current electric motor;

5 - synchronous generator;

6 - block of two automatic trip units;

7 - battery;

8 - voltage stabilizer;

9 - block of two automatic releases;

10 - battery charging device.

In this case, the first and second output, the third, first and second inputs of the block of two automatic releases 9 are respectively connected: with the first, second input, the output of the battery 1, also connected to the first input of the automatic release 2, with the first, second input of the block of two automatic releases 6 and through a battery recharging device 10, through a voltage regulator 8 with the first and second output of a synchronous generator 5, rigidly connected to a DC motor 4, the input of which is connected through a rheostat 3 s the output of the automatic release 2 having a second input connected to the third input of the block of two automatic releases 6 with the output of the battery 7.

The device operates as follows. Using the battery 1, direct current is supplied through an automatic trip unit 2 and a rheostat 3 to a direct current electric motor 4, by means of which the shaft of the synchronous generator 5 is rotated. The latter generates an alternating voltage to the stabilizer 8.

An example of a specific performance of the stabilizer is provided in the book: Yu.T. Sindeev. Electrical engineering with the basics of electronics. Rostov-on-Don, Phoenix publication, 2004, pp. 309-314, and also in the book: S.P. Kolosov and other Elements of automation. Engineering, 1970, pp. 358, 359, Fig. 207. The stabilizer outputs two phases of the stabilized voltage, which enter the recharging device of the battery 10. Thanks to stabilization, its reliable operation is ensured and the recharge time is reduced. Using the automatic release 2, the first and second inputs are connected to the battery 1 or battery 7, depending on the voltages supplied to these inputs. Using rheostat 3, the optimal mode of operation of the electric motor 4 is established. In the battery recharging device 10, the alternating voltage is converted to constant, and from its outputs the plus and minus are supplied to the units of two automatic releases 6 and 9. An example of a specific embodiment of the battery recharging device presented in the book: M.A.Shustov. Control and protection of power supplies. Publishing House Dom Dodeka 21, "Altex" 2007, p. 152, where the battery is periodically recharged when the voltage drops below the permissible value, therefore, when the voltage drops at the first input of the release 2 as a result of discharging the battery 1, the release 2 will connect the battery 7 and disconnect the battery 1. In this case, as a result of a voltage drop at the output of the battery 1, a block of two automatic releases 9 will trip and pass “plus” and “minus” from the battery recharging device 10 to the first and second battery inputs th battery 1 to be recharged. Due to the voltage drop at the output of the battery 7 after discharge, the output of the battery 1 will again be connected to the release 2 and the block of two automatic releases 7 will trip and pass the plus and minus from the charging device 10 to the first and second inputs of the battery 7. As a result, it will start charge and the process will repeat. This ensures alternating operation of the two batteries. An example of a specific implementation of an automatic trip unit is presented in the book: Electrical Engineering and Fundamentals of Electronics. E.S. Traube and V.G. Mirgorodsky, 1985. The device can be used in autonomous power supply and electrical control systems. Wheel sets, propellers, propellers, etc. can be used as actuating units. The duration of the device is increased. Batteries can be recharged by inertial movement. The voltage drop at the input of the stabilizer will not affect the charging time. The value of the power at the outputs of the generator 5 is quite sufficient for timely recharging of the battery.
