Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of the utility model embodiment low-power consumption list live wire switch.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, is the circuit theory schematic diagram of the utility model embodiment low-power consumption list live wire switch.The low-power consumption list live wire switch of the present embodiment and load L are serially connected on 220V civil power.Low-power consumption list live wire switch comprises control circuit S, transformer B1, first rectifier bridge Q1, second rectifier bridge Q2, first controllable silicon VT1, second controllable silicon VT2, first diode D1, second diode D2, 3rd diode D3, 4th diode D4, voltage stabilizing didoe DW and electric capacity C1, two terminals of the first rectifier bridge Q1 are connected on 220V civil power, two other terminals one end ground connection of first rectifier bridge Q1, the other end connects the positive pole of the 4th diode D4 and the positive pole of the first controllable silicon VT1, the minus earth of the first controllable silicon VT1, the negative pole of the 4th diode D4 connects the positive pole of the first diode D1, the negative pole of the first diode D1 connects one end of electric capacity C1 and the low-voltage direct forward output D of control circuit S, the low-voltage direct negative sense output C ground connection of control circuit S, the switch control terminal G of the control pole connection control circuit S of the first controllable silicon VT1, the positive pole of the second controllable silicon VT2 connects the positive pole of the first diode D1, the control pole of the second controllable silicon VT2 connects the positive pole of voltage stabilizing didoe DW, the negative pole of voltage stabilizing didoe DW connects the negative pole of the first diode D1, the negative pole of the second controllable silicon VT2, the positive pole of voltage stabilizing didoe DW and the other end ground connection of electric capacity C1, be connected on 220V civil power with the first rectifier bridge Q1 after second diode D2 and the 3rd diode D3 reverse parallel connection, the primary coil of transformer B1 is in parallel with the 3rd diode D3, the two ends of the secondary coil of transformer B1 connect two terminals of the second rectifier bridge Q2, two other terminals one end ground connection of second rectifier bridge Q2, the other end connects the positive pole of the first diode D1 and the negative pole of the 4th diode D4, wherein, when low-power consumption list live wire switch OFF, switch control terminal G output low level, when low-power consumption list live wire switch connection, switch control terminal G exports high level.
Specifically, the first controllable silicon VT1, can as the switch of control load L break-make owing to being unidirectional, and the first controllable silicon VT1 conducting is equivalent to switch and closes, and the first controllable silicon VT1 cut-off is equivalent to switch and disconnects.
When low-power consumption list live wire switch OFF, switch control terminal G output low level, first controllable silicon VT1 ends, now, 220V civil power is by the first rectifier bridge Q1 rectification, then, electric current flows through the 4th diode D4, the first diode D1, provides low-voltage dc power supply by after electric capacity C1 filtering to control circuit S, has ensured the supply of standby power.
When low-power consumption list live wire switch connection, switch control terminal G exports high level, first controllable silicon VT1 conducting, load L obtains electric and normally works, and has electric current to flow through, electric current must be had to flow through the primary coil of transformer B1 in load circuit, boosted by transformer B1, then by after the second rectifier bridge Q2 rectification, electric current flows through the first diode D1, provides low-voltage dc power supply by after electric capacity C1 filtering to control circuit S, has ensured that the supply of standby power is to control circuit S.Wherein, second diode D2 and the 3rd diode D3 is attempted by the primary coil of transformer B1, the voltage of primary coil is limited in about 0.7V, can prevents transformer B1 primary coil from burning out, also can prevent because load L electric current is excessive and cause output voltage too high.
Voltage stabilizing didoe DW and the second controllable silicon VT2 plays pressure limiting effect when load obtains electric, just just can conducting when output voltage is too high.After boosting, civil power becomes Rectified alternating current after transformer B1 transformation, the second rectifier bridge Q2 rectification, and due to the buffer action of the first diode D1, the second controllable silicon VT2 transfers cut-off to when voltage zero-cross each time.The initial segment part after voltage zero-cross, before output voltage does not reach stationary value, second controllable silicon VT2 not conducting, electric current flows through the first diode D1, gives circuit supply, when output voltage rises to burning voltage after electric capacity C1 filtering, voltage stabilizing didoe DW is breakdown, second controllable silicon VT2 triggering and conducting plays bypass effect, and at this moment control circuit S is powered by electric capacity C1, has nothing to do with load.In this way, repeat once in every half period, thus ensure that switch activated after power supply supply.
By the way, no matter the low-power consumption list live wire switch of the utility model embodiment is at the first controlled silicon conducting or when ending, low-voltage dc power supply can be provided for control circuit, and because low-power consumption list live wire switch is connected on single live wire, thus can single live wire power getting be realized, especially realize single live wire power getting when not changing wire laying mode.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
