Description
Technical field
The utility model relates to a kind of battery discharging unidirectional protection device, is used for the battery discharging instrument of electric power system, can prevent to cause the phenomenon of burning discharge instrument because of operate miss wrong accumulator polarity.
Background technology
At present, all nonpolarity protective device of battery discharging instrument that electric power system is used is in to battery discharging, in case because operate miss or other reasons with its polarity wrong, will inevitably burn instrument.
Summary of the invention
The purpose of this utility model provides a kind of battery discharging unidirectional protection device simple in structure, can be in the polarity wrong automatic blocking, the protection discharge instrument is not burnt, and sound, light alarm can also be provided simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
Battery discharging unidirectional protection device described in the utility model; between the battery terminal that connects accumulator anode and cathode, be connected with cartridge fuse and unidirectional protection circuit; the unidirectional protection circuit comprises forward work executive circuit in parallel; forward forward working indicating; reverse sound alarm circuit and backlight warning circuit; wherein forward work executive circuit is made of the work diode of series connection and the winding coil of relay; forward forward working indicating is made of the indication diode and the relay indicating light of series connection; oppositely sound alarm circuit is by the acoustic alarm diode of series connection; dropping resistor and buzzer constitute; the backlight warning circuit is made of the light warning diode and the alarm lamp of series connection, and the operating contact of relay is connected between battery terminal and the discharge instrument input terminal.
This battery discharging unidirectional protection device makes the discharge instrument operate as normal under the correct situation of wiring.Connect power supply from the anti-situation to discharge instrument that to cut off automatically under at battery polar, protect it not burnt, provide sound, light to report to the police simultaneously.
Description of drawings
Accompanying drawing is the electrical schematic diagram of an embodiment of the utility model.
Embodiment
As shown in drawings; battery discharging unidirectional protection device described in the utility model; at the battery terminal+KM that connects accumulator anode and cathode; be connected with cartridge fuse FU and unidirectional protection circuit between-the KM; the unidirectional protection circuit comprises forward work executive circuit in parallel; forward forward working indicating; reverse sound alarm circuit and backlight warning circuit; wherein forward work executive circuit is by the work diode V4 of series connection; the winding coil of V5 and relay J constitutes; forward forward working indicating is made of the indication diode V1 and the relay indicating light L1 of series connection; oppositely sound alarm circuit is by the acoustic alarm diode V3 of series connection; dropping resistor R and buzzer SP constitute; the backlight warning circuit is made of the light warning diode V2 and the alarm lamp L2 of series connection, and the operating contact of relay J is connected between battery terminal+KM and the discharge instrument input terminal+K.
The operating contact of relay J can be connected between electrode input end of storage battery and discharge instrument as shown in drawings, also can be connected between the negative terminal.
During work, cartridge fuse FU plays the effect of the big electric current of restriction, prevents the safety of the big current affects transformer station direct current system that causes because of internal short-circuit or earth fault.
During correct wiring, indication diode V1, work diode V4, V5 conducting, light warning diode V2, acoustic alarm diode V3 end.Cathode voltage is leaded up to indication diode V1 and relay indicating light L1 to negative pole through cartridge fuse FU, and relay indicating light L1 lights, and represents working properly; The winding coil of another road by work diode V4, V5 and relay J is to negative pole, and relay J gets electronic work, closed circuit, the discharge instrument operate as normal connected of its normally opened contact.Work diode V4, V5 are made of two diodes, and its effect is that another diode still can ensure relay work when preventing one of them diode breakdown short circuit.
During reverse wiring, indication diode V1, work diode V4, V5 end, and relay J is failure to actuate, light warning diode V2, acoustic alarm diode V3 conducting.Cathode voltage is leaded up to light warning diode V2, alarm lamp L2 to negative pole through cartridge fuse FU, and alarm lamp L2 lights, expression wiring error; To negative pole, buzzer SP rings by acoustic alarm diode V3, dropping resistor R and buzzer SP on another road, prompting wiring error.
