Abstract
The invention discloses an adjustable automatic-timing in-service and out-of-service protector for an accumulator. Two ends of a normally closed contact of an alternating current relay are connected with signal triggering ends of a hour-timing delay counter; two ends of a coil of the alternating current relay are connected with electric supply detecting ends; two ends of a normally open contact of a 40A relay are connected with signal triggering ends of a minute-timing delay counter; two ends of a normally closed contact of the 40A relay are connected with output line ends of the accumulator; a normally open contact of the hour-timing delay counter, a 12 V power supply, a coil of the 40 A relay and a normally closed contact of a direct current relay are sequentially and annularly connected; a coil of the direct current relay, the normally open contact of the minute-timing delay counter and the 12 V power supply are sequentially and annularly connected. The adjustable automatic-timing in-service and out-of-service protector disclosed by the invention can autonomously set up the accumulator discharge time, and is simple in circuit switching, high in universality of components and parts, and high in reliability of the complete device.
Description
Technical field
The present invention relates to a kind of protective device preventing storage battery deep discharge.
Background technology
At present, at UPS(uninterruptible power system), EPS(emergency power system) and the power supply system for communications in, the protection for storage battery be only limitted to electric power host shut down protect storage battery.Electric power host is by detecting cell voltage and after comparison threshold value, sending halt instruction.But in most practical application, because load is lighter, after power failure, battery carries with low discharging current banding, when electric power host detect cell voltage low time, battery is in deep discharge conditions, if attendant can not process in time or such event occurs several times repeatedly, battery is just scrapped substantially, not only affects the investment of user, also seriously jeopardizes the availability of system.
Summary of the invention
For solving prior art Problems existing, the invention provides a kind of adjustable storage battery self-clocking throwing and move back protector, its technical scheme taked is:
Comprise AC relay, direct current relay, 40A relay, in time, counts delay counter and divides a meter delay counter, the signal trigger end of meter delay counter when normally closed some two ends of AC relay connect, the coil two ends of AC relay connect civil power test side, the two ends normal battle of 40A relay connect the signal trigger end of point meter delay counter, normally closed some two ends of 40A relay connect storage battery output line terminal, time meter delay counter normal battle, 12V power supply, the coil of 40A relay and the normally closed some articulating successively of direct current relay, the coil of direct current relay, divide normal battle and the 12V power supply articulating successively of meter delay counter.
This protector utilizes relay normally closed monitoring civil power, and during power failure, relay quits work, and gets an electric shock closed, and is standard with time, time meter Time delay counter after the time timing of setting completes, disconnect storage battery and connect, make storage battery interrupt discharge condition.Utilize the action of the normally closed point of relay simultaneously, trigger a point meter delay counter, thus at one minute internal cutting off 40A relay power, make storage battery circuit recover normal.
The present invention independently can set discharge time of accumulator, and tangent line road is simple, and components and parts highly versatile, whole aircraft reliability is high.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the signal trigger end 9 of meter delay counter 2 when normally closed point 8 two ends of AC relay 1 connect, coil 7 two ends of AC relay 1 connect civil power test side 18, the two ends normal battle 16 of 40A relay 5 connect the signal trigger end 11 of point meter delay counter 4, normally closed point 17 two ends of 40A relay 5 connect storage battery output line terminal 19, time meter delay counter 2 normal battle 10, 12V power supply 6, the coil 15 of 40A relay 5 and normally closed point 13 articulating successively of direct current relay 3, the coil 14 of direct current relay 3, divide normal battle 12 and 12V power supply 6 articulating successively of meter delay counter 4.
During the work of this protector, first civil power is accessed civil power test side 18, when civil power is normal, coil 7 live line work, normally closed point 8 is in " opening " state.If mains failure, normally closed point 8 returns to " closing " state, counts the signal trigger end 9 of delay counter 2 during triggering, time meter delay counter 2 start (0 ~ 99 hour adjustable, is set to 2 hours), enter countdown state, after setting-up time arrives, export an on-off model, closed, after normal battle 10 is closed normal battle 10, make coil 15 charged, 40A relay 5 action, normally closed point 17 becomes " opening " state, thus disconnects storage battery output line terminal 19.
During 5 action of 40A relay, transfer the signal trigger end 12 that " closing " state triggers point meter delay counter 4 normal battle 16 to, a point meter delay counter 4 starts (0 ~ 99 minute adjustable, is set to 1 minute), enter countdown state, after after 1 minute, countdown terminates, a point meter delay counter 4 sends signal, and normal battle 12 is closed, after normal battle 12 is closed, coil 14 is charged, direct current relay 3 action, and normally closed point 13 becomes " opening " state.Cut off the power supply of coil 15,40A relay 5 quits work, and normally closed point 17 recovers reset condition, and storage battery output line terminal 19 recovers normal connection.
This protector 12V used power supply 6 direct-connectedly can take from storage battery, and during system cloud gray model, only delay counter is charged.
