SU922923A1 - Device for power supply of load - Google Patents

Description

The invention relates to electrical engineering and can be used to power the load from chemical current sources.

A device is known to supply the load as a power source using an accumulator made in the form of a housing and electrodes immersed in electrolyte solution C].

However, this device does not ensure the constancy of the supply voltage, due to the presence in the battery of the incident characteristic of the dependence of the discharge voltage on the length of the discharges.

It is also known a device for supplying a load, containing a battery, made in the form of a housing and electrodes immersed in an electrolyte solution, a stabilizing device in the form of a DC magnet, between the poles of which the battery is located, and a pipe system ~

2

wires with a pump for the directional movement of the electrolyte connected to the battery housing 12].

However, the known device for powering the load has a complex structure, low reliability, large dimensions and weight.

The purpose of the invention is to simplify the design, increase reliability and improve the overall mass indicators of the device.

This goal is achieved by the fact that in the device to power the load, containing a battery made in the form of a housing and electrodes immersed in an electrolyte solution, and an excitation winding used to stabilize the discharge voltage, part of at least one of the electrodes is made of a magnetostrictive material The excitation winding is connected to a high frequency current source and covers the magnetostrictive part of the electrode.

The drawing shows the proposed device, the cut.

The device for powering the load comprises a battery case 1 with an electrolyte solution 2 and electrodes 5 3 and 4 immersed in an electrolyte solution (for example, a 20% aqueous solution of KOH alkali). Electrodes are a package of plates made of magnetostriction material 10, for example, nickel. In each package, the plates are located relative to each other with gaps that are filled with active mass, for example, at the positive electrodes - 15

from nickel oxide hydrate N1 (OH). ^, and in negative ones from spongy cadmium). The plates have openings for the access of the electrolyte to the active mass. The device also contains a winding 20 excitation, covering the electrodes in their upper part. External consumers (not shown) are connected to the output terminals of the electrodes. The excitation winding is powered by high-frequency current 25 from the ultrasonic generator 6, which is under the influence of the regulator 7. The regulator 7. is designed to process information about the change in the discharge voltage of the battery and to maintain the output voltage of the ultrasonic generator proportional to the magnitude of this change.

The device for powering the load ₃₅ operates as follows.

An electrical signal proportional to the actual battery voltage supplied from the battery of the electrodes to the controller 7 "Regu- trimmer ₄₀ 7 processes information on the battery discharge voltage change and provides the ultrasonic generator 6, the electrical input signal ₄₅ whose magnitude is proportional to the difference between the nominal and the actual discharge battery voltage. The generator 6 converts the electrical signal arriving at its input into a high-frequency voltage that feeds the excitation winding 5. Variable magnetic field * winding 5 excites ultrasonic vibrations

electrodes 3 and 4, with an amplitude whose value is proportional to the decrease in the discharge voltage of the battery. The oscillations of the electrodes intensify the electrochemical processes in the battery, which leads to the restoration of its nominal voltage. Compensating for the discharge voltage drop of a battery using an ultrasonic field and using electrodes partially made of magnetostrictive material as a radiator can significantly simplify the design of the device to power the load, increase its reliability due to an increase in the speed of recovery processes, and improve the overall mass indicators of the device. At the same time, degassing, heating and mixing of the electrolyte, as well as cleaning the electrodes, is achieved.

In addition, electrolyte access to the active mass of the electrodes is improved due to the ultrasonic capillary effect.
