Description

one

The invention relates to converter technology and can be used in devices for forming and training battery battles,

A known system for charging and discharging batteries, containing a power converter, a thyristor converter, a current sensor and a stabilization circuit, the thyristor converter being fulfilled according to the sequential switching circuit of the transmitters and

inverter til. .

Lime also charge-discharge devices containing a reversible expander, the output of which connects the battery.

In charge mode, a reversible rectifier provides for the discharge of the supply voltage and the flow of the charge current, the magnitude of which is determined by the difference in the ground voltage of the emf of the battery and the resistance of the charging circuit. In the discharge mode, the reverse driver operates as a network driven one, the inverter ensuring the energy recovery of the battery discharge into the supply mains.

The disadvantage of these sistet. is the bon .-. the installed power of the equipment and the low efficiency due to the circulation of high charge and discharge energy determined by the product of the voltage on the battery and charge-discharge current, although to get a charge from the battery The current and discharge capacitance only played the value of charge-discharge current, not the voltage.

The aim of the invention is to reduce the installed power of the equipment and increase the efficiency of the cycling process.

This is achieved by introducing a DC power source into the system and connecting the battery sections into a four-arm symmetric wocT connected to the output 31 of the reverse rectifier common anodic cathode points, to the other common anodic points of which the specified DC source is connected

The drawing shows the principal (the cara of the proposed charging system. It contains the rovering exporter of the battery section 2-5, source 6 compensating for these losses. Due to the fact that the reversing level 1 does not work for the sum of the battery sections batteries (V "V -T V -V) there is a significant reduction in consumed and recuperated energy back into the grid, and, consequently, a decrease in the installed power of equipment and electrical losses, .. As a source of direct current m Any adjustable source of pulsating and impinging direct current can be used. Its power is insignificant and is determined only by the energy lost during the charging and discharging of the battery. It can also be used to pre-charge any two battery sections. batteries, for example, 35, and then the formation and imaging of the battery (or their electrode plates) can be performed according to a shifted schedule. The use of the proposed charge system in battery factories in large battery facilities is particularly effective. As a reversing rectifier, any device that is known can be used to provide reversal of direct current at its output, for example, a relay with a contact reversing device, etc. The claims of the invention, and the charging system comprising a battery, a reversible rectifier, to the output terminals of which is connected a sectioned 1-battery accumulator, which in order to reduce the installed power of the equipment and increase efficiency, it has & It is an additional DC source, and the battery and battery sections are connected in a symmetrical four-arm mos, connected to the output terminals of the reverse source with their common anode-short points and the common anode and cathode points to the output terminals of this additional source.
