Abstract

The invention relates to the electrical industry and is intended for use in the manufacture and testing of chemical current sources. The purpose of the invention is to quickly determine the place of the chain break and simply reduce the equipment. The device contains a training unit 1, which charges and discharges the batteries according to a predetermined program and stabilizes the current, the installation slots 2, equipped with contact-holding contacts 3 for fastening the batteries 4 and connected by terminals 5 to the distribution unit 6, providing alternate connection test jacks to the block for locating the open circuit 7, the pulse generator 8, the display unit 9, showing the number of the monitored socket, the power supply unit 10, the control unit for the open circuit 11, and the keys 12-14. The load node 15 and the locking key 16, which blocks the flow of pulses from the pulse generator 8 to the distribution unit 6, provides control of the integrity of the training unit circuit and in case of detection of the circuit breakage of the latter, the search for a faulty installation socket is excluded. 1 il.

Description

The invention relates to the electrical industry, is intended for use in the manufacture and testing of chemical current sources, for example, sealed battery - nickel-cadmium alkaline and is additional to auth st. No. 913490.

The purpose of the invention is to expand the functionality by more quickly detecting the location of the malfunction, and consequently, reducing the time of just equipment.

The drawing shows a block diagram of the proposed device.

The device contains a training unit 1, which charges and discharges the batteries according to a predetermined program and stabilizes the current, the installation slots 2, equipped with holding contacts 3 for fastening the batteries A and connected by terminals 5 to the distribution unit 6, ensuring alternately connecting the test slots to the block 7 detection point of an open circuit, 8 pulse generator, indication block 9, showing the number of the monitored socket, power supply block 10, open circuit control block 11, keys 12-14, load node 15 and blocking Hand key 16.

The device works as follows.

With H (playfulness of the training unit 1, which caused the disappearance of the charge-discharge current through the batteries 4), the open circuit control unit 11 is activated, which turns on the lock key 16 and the open spot detection unit 7. The latter connects the load unit 15 to the output The training unit 1 and through the key 12 disconnects the batteries 2 from the training unit 1. But since the training unit 1 is faulty, no current flows through the load node 15. The locking key 16 blocks the flow of pulses from the generator 8 pulses to the distribution unit 6, and Therefore, a false search for a faulty socket does not occur.

If the disappearance of the charge-discharge current is caused by a malfunction in the installation slot 2, then the device operates as follows.

The breakaway control unit 11 operates, which turns on the lock key 16 and the open circuit detection unit 7, which connects the load node 15 to the output of the training unit 1 and switches off the batteries 2 from the training block 1 through the switch 12. And since the training unit 1 is intact, a charge-discharge current begins to flow through the load node 15, which is reset to the initial state of the circuit 11 control circuit failure, The latter disables the blocking key 16, as a result of which the blocking of pulses is removed distribution block 6. However, the open circuit control unit 11 does not turn off the open circuit detection unit 7, therefore, the distribution unit 6 is connected via the -KEYS 13 and 16 to the pulse generator 8 and via Keys 14 to the open circuit detection unit 7 and. The distribution divider 5 (} to 6 starts automatically searching for the faulty installation socket 2. After detecting all the failures like Open in the sockets 2, the key 12 closes and the charge (discharge) circuit of the batteries is restored. Next, the open circuit detection unit 7 turns off, which disconnects the load node 15, and the keys 13 and 14 return to the initial state by disconnecting the pulse generator 8 and the open circuit detection unit 7 from the distribution block 6, and the distribution block 6 starts automatically searching for the faulty installation 2nd nest 2.

The use of a load node and a lock key allows more quickly determining the place of an open circuit, including in the training unit that caused the disappearance of the charge-discharge current, which contributes to the operational elimination of this open circuit, i.e. the reduction is simple equipment.
