Abstract
The utility model discloses an automatic protection device for charging machines, belonging to a protection device for electromechanical products. The utility model can ensure the safe work of charging machines and devices under the condition of the various accidental overload of charging machines. The utility model has the main technical characteristics that the utility model is formed by automatic protection circuits; the utility model is provided with an automatic voltage regulation part; the utility model is connected with a counter protection circuit, a sufficient automatic power-off circuit, etc. The utility model has the advantages of simple structure, safe use, high durability, and protection of safe and normal running for devices.
Description
The utility model belongs to a kind of protective device of electronic product, can make charger under various overload fortuitous events, and charger and equipment all the time can trouble free services, are not damaged.
Now the charger of employed motor vehicle on the market only plays charge function, can not transship automatic stop, connects instead in polarity, under the situation such as short circuit, and the charger utmost point is damaged, and can not protect the safe handling of charger automatically.
The purpose of this utility model provides a kind of safeties that can protect the charger trouble free service automatically, accomplishes to transship automatic stop.Connect instead in polarity, short circuit etc. do not meet under the situation of this machine output voltage, and output voltage can be protected, be refused to charging machine automatically, protected the safety of equipment.
The utility model is achieved in that mainly and constitutes by automatic protection circuit.Provide commutating voltage and the self-regulating power supply of voltage supplied respectively by power transformer, through rectification circuit with connect anti-protective circuit and be connected with sufficient power-down circuit automatically, then with the storage battery protection charging of joining.Positive and negative two utmost points of storage battery have connect instead like this; can short circuit yet; can restrain charge in batteries; protected charger; owing to connect anti-automatic protection circuit; voltage is regulated part and the sufficient measure of outage and short-circuit protection etc. automatically automatically, and charger just can play automatic protective effect, can be in normal operating conditions all the time.
Automatically the significant advantage of protection charger be simple in structure, safe in utilization, experience all sorts of durable; do not connect anti-or short circuit or overload etc. even do not pay attention to polarity during use; all insurances that does not meet the charging of this machine, charger will stop charging automatically, has protected the safety and the normal operation of equipment.
Further specify below in conjunction with accompanying drawing:
Fig. 1 is circuit theory diagrams of protecting charger automatically.
As seen from the figure, automatic protection circuit of the present utility model is like this, and power transformer provides voltage to regulate part automatically through a road of transformation, and another road provides through rectification and connects anti-protective circuit and the sufficient power supply of outage automatically.It mainly is through diode D that voltage is regulated part automatically

1Be operated in cut-off state, make B
4Both end voltage is normally exported, and connecing anti-protective circuit is like this, owing on the diode unilateral conduction is arranged, if connect inverse time with storage battery, this circuit just is in cut-off state, makes the charger negative line disconnect reaching and meets anti-protection triode G
2Conducting makes K switch
4Closure, the negative pole circuit is connected, circuit working is normal.Sufficient power-down circuit automatically is like this, and the voltage signal during according to the storage battery full charge suppresses triode G
3Conducting makes relay J
2The magnetic field that produces makes K switch
5Disconnect, make triode G
2End, reach the purpose of sufficient outage.
