Description
Technical field
The utility model relates to a kind of battery reverse-connection protection circuit of wind-light complementary system, especially can correct the protective circuit of battery plus-negative plate reversal connection automatically.
Background technology:
At present, known battery reverse connecting protection method mainly contains two kinds, and a kind of method is to add semiconductor diode between charger (or load) and battery, utilizes the unilateral conduction of diode to protect the battery reversal connection; Another kind is to add single relay between charger (or load) and battery, utilizes the single-pole double throw characteristic of single relay to protect the battery reversal connection.
For the battery reverse-connection protection circuit that adds semiconductor diode, when connecing the unilateral conduction of inverse time by diode, battery the two poles of the earth make the battery two ends become open circuit, thereby reversal connection plays a protective role to battery, but because self pressure drop is relatively large during diode current flow, loss ratio during diode operation is bigger, the also corresponding decline of the utilance of the energy content of battery, inapplicable for the not strong battery of self reserve capabillity; Simultaneously because of the unilateral conduction of diode, by single diode semiconductor, have no idea to accomplish the effect that can realize that charging circuit charges the battery, can realize that also battery gives the effect of load discharge; And in some job sites, difficulty of construction is big, in case battery connect instead, need be from new construction, increase greatly construction intensity.
For the battery reverse-connection protection circuit that adds single relay, when battery is correct when connecting, its can operate as normal, and when battery connects anti-the time, the armature in the relay is thrown to another contact, and another contact is unsettled, thus open circuit protection battery.This method is compared to utilizes diode to protect the method for battery reversal connection, and it has certain advantage, and the conduction voltage drop of relay is lower, and the power consumption during conducting is less; Be two-way because of its sense of current that allows to flow through simultaneously, this battery reverse-connection protection circuit can be realized the effect that charging circuit charges the battery, and can realize that also battery gives the effect of load discharge.But when the battery reversal connection, this guard method has no idea to protect the electric power system operate as normal, in the bigger environment of difficulty of construction, also will increase working strength from new replacing connection, and this guard method also is not too suitable.
The utility model content
The utility model proposes a kind of new protective circuit at deficiency of the prior art.
The utility model is achieved by following technical proposals:
A kind of battery reverse-connection protection circuit of wind-light complementary system is characterized in that contact 2, the ancillary coil tap 7 among the relay I, the contact 11 among the relay II, the ancillary coil tap 15 among the relay II among the relay I is connected on the electrical node;
Contact 3 among the relay I, the contact 5 among the relay I, the contact 10 among the relay II, the contact 14 among the relay II are unsettled, are not electrically connected;
The armature 1 of relay I links together with armature 4, and is connected on the electrical node with the output cathode end of wind light mutual complementing charger;
The armature 9 of relay II links together with armature 12, and is connected on the electrical node with the output negative pole end of wind light mutual complementing charger.
This novel battery reverse-connection protection circuit can make when battery operated loss less; improve the battery utilance; can realize the effect that charging circuit charges the battery by this novel battery reverse-connection protection circuit; can realize that also battery gives the effect of load discharge; as in wind-light complementary system; load is the output that hangs over the wind light mutual complementing charger, needs the battery reverse-connection protection circuit to guarantee that battery can be discharged, and also can be recharged.Work as battery simultaneously and connect inverse time, this novel battery reverse-connection protection circuit can also guarantee the wind-light complementary system operate as normal, has improved the reliability service of system, makes wind-light complementary system hommization more, easier operation.
Beneficial effect: system need not when connecting battery to consider that the battery plus-negative plate battery can operate as normal under correct situation about connecting, also can operate as normal under the situation of reversal connection; Voltage drop is less during the relay conducting, utilizes relay to substitute diode, also can play the effect that cuts down the consumption of energy; Simultaneously allow two-wayly, utilize this novel battery reverse-connection protection circuit, can realize the effect that charging circuit charges the battery, can realize that also battery gives the effect of load discharge because of the relay conducting sense of current.
