The utility model relates to an automatically controlled power switch apparatus. The apparatus includes a control circuit, a replay J1 and an output terminal. The control circuit comprises a one-chip microcomputer U1, a current sensor, a temperature sensor, an over-current alarming lamp, a load sensor, a DC source and a relay drive circuit; the one-chip microcomputer is the core of the control circuit; the control circuit acquires data and load of the temperature sensor, the over-current alarming lamp, the load sensor, the output replay J1 of the current sensor to instruct, and control the work state of the replay J1 in the on/off converting circuit with support of the application program, and abundant automatic on/off switch modes can be obtained. In the utility model, the automation degree is high; the control is accurate; the automatic power on/off switch parameters can be configured flexibly; and the automatically controlled power switch apparatus can prevent electric shock danger and save energy.
Description
Technical field
The utility model belongs to the power supply technical field of electric appliances, is specifically related to a kind of automatic control power supply switchgear.
Background technology
Automatically the switching electric switch has brought safety to huge numbers of families.During user power utilization from the panel box to the socket bringing onto load not, circuit has electricity dangerous, hand switch is also cumbersome; Automatically the switching electric switch is easy to use can accomplish that the time spent circuit does not have electricity, and circuit had electricity when load was arranged, and can supporting usefulness be installed with the PZ-30 panel box.Existing automatic energising cut-off switch device uses relay, parts such as overcurrent alarm lamp current sensor, and automaticity is low, and energising cut-off switch pattern can not satisfy higher technical requirement.
The utility model content
The purpose of this utility model is to develop a kind of automatic switching electric switchgear, and this device has load cell, multiple energising cut-off switch such as current sensor pattern, accurate load control, kinds of protect and warning function.
The concrete design proposal of the utility model is as follows:
The automatic control power supply switchgear, comprise control circuit, relay J 1 and lead-out terminal, improvement is: described control circuit is by single-chip microcomputer U1, current sensor, temperature sensor, overcurrent alarm lamp, load cell, direct supply and relay drive circuit;
The signal input part of overcurrent alarm lamp, relay drive circuit is connected with the corresponding signal output part of single-chip microcomputer U1 respectively, and the output terminal of relay drive circuit is connected with the control coil of relay J 1 respectively;
Temperature sensor output terminal, current sensor output terminal, overcurrent alarm lamp output terminal, load cell output terminal are connected with the corresponding signal input part of single-chip microcomputer U1 respectively;
The normally closed contact J1-1 of described relay J 1 connects with lead-out terminal L3; Normally opened contact J1-2 connects with lead-out terminal L3 during relay J 1 adhesive;
Direct supply provides working power for each element circuit.
Good effect of the present utility model is to make automatic energising outage electric switch increasingly automated, accurate load, electric current, voltage, controls such as temperature overcurrent, and energising power-down mode, thereby a kind of new appliance of can avoid getting an electric shock safety and energy savings.
Description of drawings
Fig. 1 is the utility model electrical schematics.
Fig. 2 is a control circuit principle of work synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, the cut-off switch device of switching on automatically comprises control circuit, relay J 1, and lead-out terminal, control circuit be by direct supply, single-chip microcomputer U1, temperature sensor, current sensor, load cell, the overcurrent alarm lamp, and the J1 driving circuit constitutes;
The signal input part of overcurrent alarm lamp J1 driving circuit is connected with the corresponding mutually signal output part of single-chip microcomputer respectively; The output terminal of J1 driving circuit is connected with the control coil of relay J 1 respectively;
The temperature sensor output terminal, dc power supply terminal, current sensor output terminal, load cell output terminal, overcurrent alarm lamp are connected with the corresponding signal input part of single-chip microcomputer respectively;
Direct supply provides working power for each element circuit.
Relay J 1 a transfer contact normally closed contact J1-1 respectively is connected with single-chip microcomputer; Another root normally opened contact J1-2 is connected with the alternating current incoming line.
Load cell one end is connected with single-chip microcomputer, and an end is connected with J1-1 is normally closed, and output does not have electricity when not connecing load, makes the whole family not around electromagnetic field, thus Electrical Safety.
The single-chip microcomputer end, one group of normally closed contact J1-1 of not adhesive of relay connects with lead-out terminal L3, and one group of contact of relay adhesive transfers normally closed contact J1-2 to and connects with lead-out terminal L3.
The electrical equipment that circuit has electricity can supply with family during the external various load of output terminal N4-L3 normally uses.
When output terminal N4-L3 did not connect various load, output did not have the life in electricity and no magnetic field.
Automatically energising cut-off switch device inserts civil power, by single-chip microcomputer U1 collecting temperature sensor under the support of application program, current sensor, the overcurrent alarm lamp, the data and the load of load cell are instructed, and the output control signal duty of coming control circuit repeat circuit J1, the control signal that single-chip microcomputer outputs to a relay drive circuit has two states, high level signal and low level signal, therefore a relay also has two kinds of duties, adhesive and disconnection work, and main circuit has two kinds of energising off-positions like this, load onto automatic energising cut-off switch now, just effective head it off.
