Abstract
The utility model relate to a kind of single live wire power getting device, comprise transformer, first diode, second diode, rectifier bridge, electric capacity, adjustable resistance, described first diode and load are serially connected on household electric live wire, transformer elementary is with the first diode and connect, transformer secondary output is connected with wherein two links of rectifier bridge, wherein one end ground connection of two other link of rectifier bridge also connects one end of electric capacity, the other end connects the other end of electric capacity and the positive pole of the second diode, the negative pole of the second diode connects one end of adjustable resistance, the other end of adjustable resistance exports low-voltage DC.The utility model, when not changing original wiring, adopts the mode of single fiery power taking to home controller and uses galvanic load supplying, is convenient to install, practical.
Description
Technical field
The utility model relates to single live wire power getting technical field, specifically a kind of single live wire power getting device.
Background technology
In Smart Home field, electrical appliance mostly will use zero line and live wire, and renovated after, a live wire is only had in 86 magazines, when not changing former wiring, then a lot of the intelligent domestic appliance controller is difficult to use, so need to adopt single live wire power getting technology head it off.
Utility model content
Not enough for above-mentioned prior art, the utility model provides a kind of and is convenient to installation, practical single live wire power getting device.
A kind of single live wire power getting device that the utility model provides is achieved through the following technical solutions:
A kind of single live wire power getting device, it is characterized in that: comprise transformer, first diode, second diode, rectifier bridge, electric capacity, adjustable resistance, described first diode and load are serially connected on household electric live wire, transformer elementary is with the first diode and connect, transformer secondary output is connected with wherein two links of rectifier bridge, wherein one end ground connection of two other link of rectifier bridge also connects one end of electric capacity, the other end connects the other end of electric capacity and the positive pole of the second diode, the negative pole of the second diode connects one end of adjustable resistance, the other end of adjustable resistance exports low-voltage DC.
The beneficial effects of the utility model are: when not changing original wiring, adopt the mode of single fiery power taking to home controller and use galvanic load supplying, are convenient to install, practical.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
A kind of single live wire power getting device as shown in Figure 1, comprise transformer B, first diode D1, second diode D2, rectifier bridge Q, electric capacity C, adjustable resistance VR, described first diode D1 and load L is serially connected on household electric live wire, transformer B elementary is with the first diode D1 and connect, transformer B level is connected with wherein two links of rectifier bridge Q, wherein one end ground connection of two other link of rectifier bridge Q also connects one end of electric capacity C, the other end connects the other end of electric capacity C and the positive pole of the second diode D2, the negative pole of the second diode D2 connects one end of adjustable resistance VR, the other end of adjustable resistance VR exports low-voltage DC.
In the utility model, because there is electric current to pass through in load circuit, electric current flows through the primary coil of transformer B, is boosted by transformer B, then by after full-bridge Q ballast, exports low-voltage DC.
The above embodiment only represents execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to the utility model protection range.
