Abstract
The utility model provides a protective outlet for charging of a battery jar. Structurally, an outlet, a creepage breaker and a control panel are electrically connected in an insulative case. The voltage signal of the battery jar controls outage of the creepage breaker through the control panel. When the utility model is used for charging of the battery jar, the battery jar is prevented from excess voltage. The control panel consisting of an operational amplifier and a silicon controlled rectifier is an original part.
Description
Technical field:
When the utility model is the storage battery charging, to the storage battery overvoltage protection.
Background technology:
During the storage battery charging,, damage storage battery because battery charger failure or misoperation cause charging voltage too high.
Summary of the invention:
When storage battery charged, charging voltage was too high, damaged storage battery, and the utility model provides a kind of supply socket, and is too high when charging voltage, can disconnect the power supply of charger.
The technical scheme that its technical problem that solves the utility model adopts is: in insulated case, supply socket, residual current circuit breaker, control board are housed.Storage battery is when charging, and the attaching plug of charger inserts on the utility model; Storage battery holding wire of the present utility model is received the positive and negative electrode of storage battery correspondence.Too high when charging voltage, (model: DZL18) outage, storage battery has been protected in the charger outage to residual current circuit breaker.
The control board principle: the storage battery holding wire is received by K switch 1, K2, resistance R 1, R2, R3, the corresponding positive and negative end of the sampling loop that diode D1, D2 form.K1, K2 protect loops to the conversion of signals of coming from the storage battery negative pole to 12 volts of protections of 6 volts protections of resistance R 1, R2, R3 24 volts, and (R1, R2, R3 are respectively hundreds of kilo-ohm resistance; the storage battery measuring-signal is 220 volts, also can not influence the operate as normal of storage battery charge protection socket).At 6 volts grades: the storage battery measuring-signal surpasses 9 volts, the outage of protection socket.At 12 volts grades: signal surpasses 16 volts, the outage of protection socket.At 24 volts grades: signal surpasses 28 volts, the outage of protection socket.
The voltage drop of diode D1, D2 is input to 2 pin and 3 pin of operational amplifier LM358, and amplifying signal is added to 5 pin by the output of 1 pin through resistance.When 5 pin current potentials during less than 6 pin current potentials, 7 pin output negative potential; When 5 pin current potentials during greater than 6 pin current potentials, 7 pin output positive potential.The cell voltage signal that has only amplification is during greater than 6 pin current potentials, and controllable silicon MCR100-6 just understands triggering and conducting, little relay J adhesive action.Adjust the numerical value of sample of signal loop resistance R1, R2, R3, make them respectively under the sampling voltage of regulation, little relay J adhesive, the outage of storage battery charge protection socket.R1, R2, R3 marks numerical value in circuit diagram only for reference.
The power supply of control board: small transformers is to be with centre tapped two 15 volts of transformers, just the utmost point is received the residual current circuit breaker lower end by P cock K3, the inferior utmost point connects the diode bridge rectification, and the direct current of rectification becomes+15 volts and-15 volts of control power supplys through two three-terminal voltage-stabilizing pipe KA7815, KA7915.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model
Fig. 2 is the winding diagram that the utility model is used for a storage battery.
Fig. 3 is the winding diagram that the utility model is used for many storage battery series connection.
Among the figure: (1) is the wiring of storage battery signal, and (2) are residual current circuit breaker, and (3) are supply sockets, and (4) are storage batterys, and (5) are chargers, and (6) are the utility model.
Embodiment:
In Fig. 1, according to the voltage protection gear (selected) of the selected the utility model (6) of storage battery (4) rated voltage numerical value, the two numerical value unanimity by change over switch K1, K2.In Fig. 2, the situation of a storage battery (4), the storage battery holding wire (1) of the utility model (6) receive storage battery (4) corresponding+,-extremely go up; In Fig. 3, the situation of many storage batterys (4) series connection, storage battery holding wire (1) receive first storage battery (4) that joins with charger (5) corresponding+,-extremely go up.Connect the wiring of charger (5) with storage battery (4).The plug of charger (5) inserts the utility model (6).The plug of the utility model (6) inserts the 220V power supply, the switch of the residual current circuit breaker of closing (2), and the control board mains switch K3 that closes, power lights is bright.End of operation.In case the charging voltage of storage battery (4) surpasses the protection value, the utility model (6) outage, charger (5) outage.
When the utility model (6) was used as other electrical appliance power supply, the switch of the residual current circuit breaker of closing (2) disconnected control board mains switch K3, and power lights extinguishes.
Claims (1)
