Background technology
Street lamp is a utility, and government not only bears the electricity charge of great number, also is unfavorable for the realization of low-carbon (LC) target.
Inductive power transfer is a kind of mode of contactless power delivery; " the inductive power supply device " of the wherein a kind of power delivery mode number of being disclosed CN1771570 is disclosed, this device comprise the primary coil that connects power circuit and connect one or more loads for example lamp secondary coil and be used to change physical distance or relative bearing between primary coil and the secondary coil so that sense of control is answered the mechanism of electric supply installation amount of power.
The feasibility of above-mentioned inductive power transfer mode has obtained confirmation on lighting lamp.
Yet, elementary, the secondary coil of above-mentioned contactless power delivery mode as if with transformer ' s type seemingly, its energy-saving effect is unknown.
The utility model content
The purpose of the utility model is the inductive power supply device that discloses a kind of street lamp, and this device has demonstrated fully the energy-conservation characteristics of inductive power supply.
The utility model is taked following technical scheme for realizing above-mentioned purpose: this street lamp inductive power supply device is included as the mains ac power supply line of street lamp power supply, road lamp power supply; It is characterized in that: said AC power cord is the working bus bar of this device; The electric current of working bus bar is at least 50A; Be distributed with induction power taking unit on the working bus bar; Said induction power taking unit is made up of the isolating diode that is distributed in each straight-through current transformer on the working bus bar, is connected to the bridge rectifier of each straight-through current transformer output and is connected to each bridge rectifier '+' utmost point output; The output of each isolating diode is connected to form the output of induction power taking unit, and said induction power taking unit output is connected in the low pressure street lamp that is in parallel.
The utility model can also be taked following technical measures:
Each bridge rectifier output voltage of said induction power taking unit is 35-45V, and output current is 0.2-0.5A.
The current ratio of said working bus bar and straight-through current transformer is 10-20: 1.
The nominal voltage of said low pressure street lamp is 12V, 24V or 36V.
The beneficial effect and the advantage of the utility model are: this street lamp inductive power supply device obtains electric energy from the mains ac power supply line induction field of street lamp power supply, road lamp power supply, and this electric energy is the induced current that each straight-through current transformer obtains to be superposeed respectively become low pressure street lamp inductive power supply power supply after full-wave rectification.The load capacity of each induction power taking unit depends on the size of superimposed current after size and the full-wave rectification of working bus bar electric current.Evidence; The size of working bus bar electric current only influences the load capacity of induction power taking unit and does not influence the quantity that its traction is responded to the power taking unit; For example electric current is the working bus bar of the 1000m of 50A, and traction 5 inductions power taking unit and traction 10 inductions power taking its each full-wave rectifier output voltage of unit and electric current are constant.The utility model is that street lighting provides a kind of new supply power mode by the street lamp of consumed power with the mode that the low pressure street lamp of induction power taking engages, and has the outstanding advantage of remarkable saving electric energy, the reduction electricity charge.
Description of drawings
