Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of embodiment of the present invention single live wire power getting switch.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, is the circuit theory schematic diagram of embodiment of the present invention single live wire power getting switch.Single live wire power getting switch and the load L of the present embodiment are serially connected on 220V civil power.Single live wire power getting switch comprises control circuit S, transformer B1, first rectifier bridge Q1, second rectifier bridge Q2, controllable silicon SCR, first diode D1, second diode D2, 3rd diode D3 and electric capacity C1, two terminals of rectifier bridge Q1 are connected on 220V civil power, namely the A in figure, between B node, two other terminals one end ground connection of rectifier bridge Q1, the other end connects the positive pole of the first diode D1 and the positive pole of controllable silicon SCR, the minus earth of controllable silicon SCR, 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 other end ground connection of electric capacity C1, 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 controllable silicon SCR, 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 B3, 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 low-voltage direct forward output D, wherein, when single live wire power getting switch OFF, switch control terminal G output low level, when single live wire power getting switch connection, switch control terminal G exports high level.
Specifically, when controllable silicon SCR is owing to being unidirectional, can as the switch of control load L break-make, controllable silicon SCR conducting is equivalent to switch and closes, and controllable silicon SCR cut-off is equivalent to switch and disconnects.
When single live wire power getting switch OFF, switch control terminal G output low level, controllable silicon SCR is ended, now, 220V civil power passes through the first rectifier bridge Q1 rectification, then, electric current flows through 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 single live wire power getting switch connection, switch control terminal G exports high level, controllable silicon SCR conducting, and load L obtains electric and normally works, and has electric current to flow through, electric current must be had to flow through primary coil and the first rectifier bridge Q1 of transformer B1 in load circuit.Boosted by transformer B1, then by providing low-voltage dc power supply to after the second rectifier bridge Q2 rectification control circuit S.There is provided low-voltage dc power supply also to after the first rectifier bridge Q1 rectification 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.
By the way, no matter the single live wire power getting switch of the embodiment of the present invention is at controlled silicon conducting or when ending, low-voltage dc power supply can be provided for control circuit, and because single live wire power getting 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 embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention 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 invention.
