Description of drawings

Fig. 1 is the circuit theory diagrams of the utility model one embodiment.

Embodiment

Fig. 1 is the circuit theory diagrams of the utility model one embodiment, comprises respectively the parallelly connected first transformer T1 and the second transformer T2 between live wire and zero line; The secondary coil of the first transformer T1 obtains galvanic current after through bridge rectifier, filter circuit and voltage stabilizing circuit and presses V1; Direct voltage V1 directly is added in the coil two ends of first relay J 1, and the normally opened contact of the 3rd diode D3 of direct voltage V1, forward, load, first relay J 1 and rechargeable battery constitute the loop; The voltage that the secondary coil of the second transformer T2 obtains after through rectification circuit, filter circuit and voltage stabilizing circuit directly is added in the two ends of second relay J 2; Rechargeable battery constitutes the loop through the normally-closed contact and the bulb of first relay J 1; The 4th diode D4 of direct voltage V1, forward, the normally-closed contact of second relay J 2 and bulb constitute the loop.

It also comprises being connected in parallel on opens module by force between live wire and the zero line, opens module by force and is arranged in the distribution box.Open module by force and be in series by the coil of the first button SB1, the second button SB2 and contactor, the normally opened contact of contactor is parallelly connected with the second button SB2, and wherein the first button SB1 is normally closed, and the second button SB2 often opens; The series connection first diode D1 on the live wire bus, the first diode D1 is parallelly connected with the normally-closed contact of contactor; Connect second a diode D2 in the opposite direction before the primary coil of the described second transformer T2 with the first diode D1.

When the 220V ac power supply just often, the 25V alternating current on the transformer T1 secondary coil obtains the voltage about about 30V by 1 filtering of first capacitor C again after the rectifier bridge full-wave rectification, carry out voltage stabilizing and reach 12V through pressurizer 7812.The DC power supply V1 of this 12V directly is added in the coil two ends of first relay J 1, makes 1 adhesive of first relay J.Like this, the normally opened contact of first relay is closed, and to battery E charging, normally-closed contact breaks off DC power supply V1 after the 3rd diode D3, second resistance R, 2 current limlitings, and battery E and bulb L break off.Meanwhile the 220V AC power obtains half-wave current through the second diode D2; Obtain 30V semisinusoidal alternating current through transformer T2 again; After the rectifier bridge rectification, obtain the voltage about about 13V by 2 filtering of second capacitor C again, carry out voltage stabilizing through pressurizer 7812 again and reach 12V.This voltage directly is added in the coil two ends of second relay J 2, and second relay J, 2 normally-closed contacts are broken off, and guarantees that DC power supply V1 does not give bulb L power supply.

If have a power failure, first relay J, 1 normally opened contact switch discharges because of coil losing electricity, and the normally opened contact of first relay J 1 is opened, and has stopped the charging to battery E.Meanwhile, the normally-closed contact of first relay J 1 is closed, and battery E just supplies power to emergency light L, thereby has reached the purpose that emergency lighting is provided after the power failure automatically.When service restoration just often, the state of relay normally open, normally-closed contact switch is conversion each other again, just automatic disconnection of emergency lighting circuit for lamp, and battery E charged again.

If light fixture is opened by force, press the second button SB2, it is electric to make that contactor KM gets, and its normally opened contact closure makes it to continue to connect, and normally-closed contact breaks off and makes the first diode D1 place in circuit.Like this, just the 220V alternating current has been carried out halfwave rectifier.Through the first transformer T1, obtain the voltage about about 15V behind the rectifying and wave-filtering, carry out voltage stabilizing through pressurizer 7812 again and reach 12V.This voltage directly is added in the coil two ends of first relay J 1, makes 1 adhesive of first relay J.Like this, the normally opened contact of first relay J 1 is closed, and to battery E charging, the normally-closed contact of first relay J 1 breaks off DC power supply after the 3rd diode D3, second resistance R, 2 current limlitings, and battery E and bulb L break off.Meanwhile; Because second a diode D2 with the first diode D1 anti-phase is arranged before the second transformer T2; Make that the second transformer T2 voltage is 0; Second relay J 2 is failure to actuate, and the normally-closed contact of second relay is closed, by coming out bulb L to be supplied power through the 4th diode D4 through the voltage of rectifying and wave-filtering through the first transformer T1.

The 3rd diode D3 among the figure is an isolating diode.If there is not the 3rd diode D3, when AC power was cut off the power supply, the electric current of battery made relay still keep attracting state through the normally opened contact of first relay J 1, second resistance R 2, first relay J, 1 formation loop, and bulb L does not just work.After connecting the 3rd diode D3, stoped battery E to the 1 reverse power supply of first relay J, after the power failure, bulb just can be shinny.In like manner, the 4th diode D4 also is an isolating diode, and battery E gives first relay J 1 power supply when preventing to have a power failure.The resistance of second resistance R 2 is selected relevant with different charging currents.
