SU913490A1 - Device for training and rejecting small-dimension storage batteries - Google Patents

Description

The invention relates to the electrical industry and is intended for use in the manufacture and testing of chemical current sources, for example, batteries sealed cylindrical Nickel-cadmium alkaline.

A device for training, sorting and sorting according to the electric capacity of small batteries is known, containing load resistances, a contact device, a rack with battery slots, a system of electromagnets for holding batteries in the discharge circuit contacts ₍ associated with relay units [13.

The closest in technical essence to the invention is a device for training, screening and sorting according to the electrical capacity of small-sized batteries, where the vertical non2 is used together.

movable shield with sockets provided with contact holders serving to attach and supply batteries, a training unit that charges and discharges accumulators according to a preset program, a measuring and distribution unit that controls battery voltage, and a device for ejecting battery holders

For this purpose the device is characterized failures such as "Open", caused by disturbance of the contact in the sockets defined between the batteries ¹⁵ and con tact-holders, for example because of oxidation, "mechanical fatigue" or hull deformations under the effect of gassing elements in them in the course of training '

or other reasons. The search for the place of a cliff is carried out manually by ringing out the installation sockets, which leads to equipment downtime. If the search time for the place of the cliff is large, then. All batteries installed in the device must complete a> repeated test cycle, since the process must be continuous and discontinuous (discharge) ”

The purpose of the invention is to expand the functional capabilities of the device,

This goal is achieved by the fact that the device for training and. rae- ₁₀ rejection of small batteries, ^: . containing, a training unit connected to series-connected between, a nest, equipped with contact-holder for attaching batteries connected to the distribution unit, one of the outputs of which is connected to the power supply, the pulse generator and the display unit. circuit., the detection unit of the place of open circuit. and associated keys, one of which is connected between the training unit and the sockets connected in series, the other between the pulse generator and the distribution unit, and the third between the second output of the distribution unit and the open circuit detection unit associated with the other output power source.

Ia the drawing shows the block diagram of the proposed device.

The device contains a training unit 1, which charges and discharges the batteries according to a 'given program and performs current stabilization, installation slots 2', equipped with contact-holders. 3 for fastening a-batteries 4 and connected terminals 5 with a distribution unit 6, providing alternate connection of the test jacks to the break detection unit 7, pulse generator 8, display unit 9, showing the number of the jack being monitored, power supply 10. control unit open circuit 11 and keys 12-14.

The device works as follows.

If the contact between the battery 4 and the contacts-holders of the 3-slot 2 is broken, the charge (discharge) circuit of the batteries 4 is broken, the disappearance of the current in the circuit triggers the open circuit control unit 11, which turns on the open circuit detection unit 7. The latter acts on the keys 12- 14. With an atom

the key 12 disconnects the training unit 1 from the socket 2, the key 14 closes and connects the block for detecting the location of the open circuit 7 to the distribution unit. 6 ,. The distribution unit 6 provides a consistent poll of slots 2, connecting alternately output.

5 contact holders. 3 'each nest 2, one -. to the power source 10, and the other to the block for detecting the location of an open circuit 7, If the socket-holder-contacts 3 are in normal contact with the battery 4, then the output of the power source 10 connected to the distribution unit 6, terminal 5 of the holder-contact 3, battery 4, another contact-holder 3 and its pin 5, a key 14, a block for detecting the location of an open circuit 7 and its associated input of the power source 10 a current flows that generates signals to turn on the key 13. The latter operates and connects the pulse generator 8 to distribution unit 6.

From the pulse generator 8, the signals are sent to the distribution unit 6, and after each pulse, the latter alternately connects the pins 5 of the sockets 2, If the battery 4 is not in contact with the holding contacts 3 in the slot 2, then the current does not flow through the detection unit 7 therefore, the key 13 is not turned on, and no current flows to the distribution unit 6 of clock pulses from the pulse generator 8 and it stops. On the light indicator 9, the number of the faulty slot 2 is on.

With the elimination of the open in the socket 2, the block for detecting the open circuit 7 is activated again, the key 13 closes? From the pulse generator 8, a signal is sent to the switchgear 6, which takes the next step, connecting the next slot 2 to the device for detecting the location of the wedge _: 7. (discharge) of batteries 4. Next, the open circuit control unit 11 and the open location detection unit 7 are turned off, the keys 13 and 14 are returned to the initial state, disabling the pulse generator 8 and the open location detection unit 7 from the distribution unit 6.

The present invention allows

serviceability of the type "break". Significantly reduces the time of troubleshooting and equipment downtime. In addition, the proposed device allows detecting installed elements with defects: internal breakage and high internal resistance. ·
