The technical solution adopted in the utility model is: the output that input positive and negative electrode that connects storage battery and the band positive and negative electrode that is connected power consumption equipment are arranged, be made up of double-contact relay (K1, K2) and 4 diodes, it is characterized in that: the automatic guide circuit is connected to normally closed some K112 of K1-1 of relay (K1) and normal battle and relay (K1) coil one pin of K1-2 in the direct current input cathode; Anodal normal battle and the normally closed point of K1-2 and the negative pole of diode (D1) that connects the K1-1 of relay (K1), diode (D2) is striden joint at relay (K1) two ends negative pole, and two common port K1-1, K1-2 of relay (K1) are then respectively as the negative pole and the positive pole of automatic guide circuit output end.Relay K 1 coil reverse bias under the effect of D1 diode, relay normally open point disconnect, normally closed point close and.Storage battery negative pole, the anodal common port that is connected to K1-1, K1-2 at normally closed by K112, the K122 of K1-1, K1-2; Otherwise, connect positive pole negative pole, " deceiving " that input " red " connects storage battery, the coil of relay K 1 the relay normally open point is closed and, normally closed point disconnects.Storage battery positive pole, negative pole by normal battle K121, K111 be connected to the common port of relay K 1-2, K1-1, its result is exactly that the polarity of no matter storage battery just connects (red "+", black connect "-" of connecing) or reversal connection (black "+", red connect "-" of connecing), common port, storage battery negative pole that the storage battery positive pole all has been connected to K1-2 have been connected to the common port of K1-1, thereby have realized the automatic conversion of polarity.
Low electric situation often appears in storage battery in actual use, all there is the supervision effect to battery voltage in general import equipment, when appearring in storage battery, low electricity (voltage is lower than 10.7V) can change, but storage battery is non-movable the arrangement, as unwanted, the used and open-air electronic equipment that can not monitor aborning, condition is next can not to be monitored.If at this moment voltage is lower than 7V, it is skimble-skamble to circuit that power supply inserts electric power system, and when the both positive and negative polarity reversal connection of input occurring, because voltage is lower than the voltage limit of the actuating of relay, cause relay K 1 do not inhale and, thereby make storage battery positive pole, the K1-1 of negative pole cut-in relay K1, the common port of K1-2, will cause reversal of power to insert power consumption equipment, can cause equally and blow insurance or burn the power consumption equipment situation.Take place for overcoming above-mentioned wrong accident; protective circuit is the output series connection single contact relay (K2) at the automatic guide circuit; the K1-1 of relay (K1) is connected to the protective circuit output plug as the negative pole of no reverse dc power supply; the K1-2 of relay (K1) is connected to the normal battle and diode (D3) positive pole of relay (K2) as the positive pole of no reverse dc power supply; diode (D3) negative pole connects relay (K2) relay coil, and relay (K2) common port is connected output head anode with the coil other end.Control coil cross-over connection diode (D4) negative pole of relay (K2) links to each other with diode (D3) negative pole.When the low electricity of power supply, voltage be lower than that actuating of relay limit K2-1 does not close and, output does not have voltage output; During reversal connection because the reverse bias effect of diode D4, relay do not close yet and, output is blocked, thereby power consumption equipment is played a protective role.This design input realizes by getting an electric shock to the control between the output, therefore the contact close with situation under, do not have voltage drop.
Operation principle: consult accompanying drawing.Connect inverse time at power positive cathode,, can realize automatic direction regulating by the relay contact conversion by the detection of charger.Not adhesive of relay contacts under the normal power supply state, power supply is power supply station power supply by relay K K112, K122 at 1 normally closed.Connect inverse time at power positive cathode, but relay automatic direction regulating in the charger provides correct supply power voltage polarity by relay K 111, K121 guiding back for the power supply station.Low and power supply is extremely positive and negative at supply voltage in addition connects inverse time, because brownout can not make the supply relay adhesive, supply relay is output as opposite polarity, can cause equipment to cause device damage because of polarity problems equally.The design has considered this problem; designed single contact relay K 2 again; because relay K 1 is failure to actuate and is caused error-polarity connection of power supply, and protection single contact relay K 2 coils are under the effect of series diode D4 reverse bias, the K2-1 of often making war disconnects under low electric condition.Guarantee that reverse voltage can not be added on the power supply station.This design automatic guide and protective effect all produce by the contact conversion, so entire circuit is input to output and does not have voltage drop.
