Background technique
In electric substation's maintenance process, maintenance employee has found that the battery group capacity in DC power supply is insufficient, is not achieved and sets
Meter requires.Script projected life 5 years or so battery groups have only used 2 years in electric substation, and capacity decline is obvious to be needed more
Change, found in inspection information and look for reason during, chief reason be exactly battery use and maintenance in terms of ask
Topic, battery is on the shelf for a long time or battery is made to be in floating charge state for a long time without discharging, and will lead to a large amount of in battery
Lead sulfate is adsorbed onto the cathode surface of battery, forms " sulfation " of cell cathode plate, since lead sulfate itself is a kind of exhausted
Edge body, being formed for it will generate deleterious effect to the charging-discharging performances of battery.Therefore the sulfate formed on cathode plate
More, the internal resistance of battery is bigger, and the charging-discharging performances of battery are poorer, and service life is shorter, at present.Battery is most
Number only charges, does not discharge all under long-term floating charge electricity condition, and this working condition is extremely unreasonable, forms cell cathode plate
" sulfation ", increased dramatically accumulator internal resistance, make the actual capacity (A.h) of battery well below its normal capacity,
The practical backup time that can be provided so as to cause battery greatly shortens, and reduces its service life.So battery is every
Primary every charge and discharge in 3-4 months, the electric discharge effect of rated capacity 20%-30% is exactly to activate pole plate, in order to avoid long-term floating charging causes
Pole plate softening.Therefore our automatic regular electric discharge devices for designing and producing are realized and are automatically discharged dimension to the timing of battery group
Nurse makees, and avoids battery long-term work in floating charge state, causes accumulator plate that sulfation reaction occurs.
Summary of the invention
To solve the problems in the background art, the invention proposes a kind of electric control circuits that can pass through to battery
Carry out the device of the regular automatic discharging of battery group of automatic discharging.
Technical solution: a kind of device of the regular automatic discharging of battery group, including timing control loop, control of discharge return
Road, the timing control loop include timer DS, counter JS, and wherein timer DS coil is connected to external AC power source
On, the contact timer DS and counter JS coil are connected in series in external AC power source, are wrapped in the discharge control loop
Include battery, discharge resistance, DC voltage relay KV, time-delay relay S, main relay KM, auxiliary relay KM2, wherein
Battery one end in parallel with DC voltage relay KV is separately connected by main relay KM charging contact and discharge contact
External power supply anode, discharge resistance input terminal, the other end connect external power supply cathode, and discharge resistance output end connects external power supply
Cathode；The contact auxiliary relay KM2 connect external power supply anode with counter JS contact shunt one end, and the other end passes through
The contact DC voltage relay KV is separately connected main relay KM coil input end, time-delay relay S input terminal, auxiliary relay
KM2 input terminal, main relay KM coil output, time-delay relay S output end, auxiliary relay KM2 output end pass through delay
Relay S connection external power supply cathode.
Beneficial effect is: by using technical solution of the present invention, periodically putting automatically to battery group as needed
Electricity；Discharge cycle can sets itself；Discharge capacity can be set；Normal operation can be automatically engaged after electric discharge to continue to charge.
Detailed description of the invention
Fig. 1 is discharge control loop circuit diagram of the present invention.
Fig. 2 is timing control loop circuit diagram of the present invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
By Fig. 1, a kind of device of the regular automatic discharging of battery group shown in Fig. 2, including timing control loop, electric discharge control
Circuit processed, the timing control loop include timer DS, counter JS, and wherein timer DS coil is connected to external exchange
On power supply, the contact timer DS and counter JS coil are connected in series in external AC power source, the discharge control loop
It goes up including battery, discharge resistance, DC voltage relay KV, time-delay relay S, main relay KM, auxiliary relay KM2,
Wherein, battery one end in parallel with DC voltage relay KV is distinguished by main relay KM charging contact and discharge contact
External power supply anode, discharge resistance input terminal are connected, the other end connects external power supply cathode, and the connection of discharge resistance output end is external
Power cathode；The contact auxiliary relay KM2 connect external power supply anode, the other end with counter JS contact shunt one end
By the contact DC voltage relay KV be separately connected main relay KM coil input end, time-delay relay S input terminal, auxiliary after
Electric appliance KM2 input terminal, main relay KM coil output, time-delay relay S output end, auxiliary relay KM2 output end pass through
Time-delay relay S connection external power supply cathode.
Specifically, the present invention is mainly made of timing means, discharge control device, load discharge resistance three parts, benefit
It is combined with timer DS and counter JS, the every output start-stop counter JS of timer DS adds up, and reaches counter JS
Setting value after, counter JS output control battery discharge loop, realize timing automatic discharging；Counter JS coil obtains electric touching
After point closure, discharge circuit is switched on, and auxiliary relay KM2 coil obtains electrical contacts closed, is realized and is put the continued power in circuit,
Self-locking holding；At this moment, DC voltage relay KV judges battery voltage, if battery voltage is lower than setting value,
The contact DC voltage relay KV disconnects, and cutting auxiliary relay KM2 coil voltage contact disconnects, and main relay KM coil must not
Electricity, charging contact closure, discharge contact disconnects, if battery voltage is higher than setting value, DC voltage relay KV is closed contact
Close, auxiliary relay KM2 coil persistently it is electric, host relay KM coil obtain it is electric, discharge contact be closed charging contact disconnect, storage
Battery is discharged by discharge resistance, and when battery voltage is lower than setting value, the contact DC voltage relay KV is disconnected, and is restored
Charged state realizes automatic inflatable Electricity Functional；During continuous discharge, time-delay relay S coil also persistently it is electric, when putting
The point time is more than putting the time for time-delay relay S setting, and the contact time-delay relay S disconnects, and cuts off discharge loop, restores to fill
Electricity realizes discharge time protection.
