Abstract
The invention discloses a clamping power supply, which belongs to the technical field of power supply. For development, overhead medium-high voltage transmission line (including under river cable) is provided with electronic monitoring and instructing equipment, but the power supply of the equipment cannot be obtained from the ground due to high insulation requirements. In the conventional battery power supply mode, energy runs out in a short time period. The clamping power supply comprises a clamping connector connected with the transmission line, a wire and an inductive power extraction device, wherein the inductive power extraction device comprises a magnetizer wounded with a coil, a rectifying circuit and a holding circuit. The power supply can extract power from the transmission line to supply the power to the electronic monitoring and instructing equipment.
Description
Technical field
The invention belongs to power technique fields, be specifically related to a kind ofly be applicable to that getting of grid power transmission line can power supply.
Background technology
The electric power transmission development is swift and violent, and high voltage overhead line (containing the river cable) is more and more.Along with popularizing of intelligent grid, can be equipped with multiple electronic monitoring equipment on each mesohigh power transmission line, mountain area, fog-zone and night, some also need indicate hedging.The electronic monitoring of long-term work and indicating equipment power supply are difficult to obtain from ground, the frequent powered battery mode that adopts, its power supply energy in the short period of time can be depleted, changes very inconvenience, even impossible fully, the result can cause electronic monitoring and indicating equipment to work.The induction energy fetching power supply that requires the direct punching of power transmission line to pass through can not be applied on the mounted mesohigh power transmission line, and the induction energy fetching power volume that opening is installed is huge, and weight heightens, and is not suitable for the mesohigh power transmission line.
Summary of the invention
The object of the present invention is to provide one directly get from the power transmission line can power supply, as long as power transmission line has electricity, even in a period of time that has a power failure, can guarantee the electronic monitoring and the indicating equipment operate as normal that are equipped with on the mesohigh power transmission line.
For realizing purpose of the present invention, adopt following technical scheme:
A kind of clamping power supply that is applicable to the mesohigh power transmission line, comprise folder formula coupling, conductor and induction energy fetching device, described folder formula coupling is two, be connected on the power transmission line respectively, and two folder formula couplings are coupled to each other by conductor each other, thereby form the loop with above-mentioned power transmission line, and described induction energy fetching device is arranged between the two folder formula couplings, conductor passes therethrough, to produce induced voltage.
Folder formula coupling of the present invention is conductive, is fixed on the described power transmission line.
Induction energy fetching device of the present invention comprises magnetic conductor, rectification circuit and the holding circuit that is wound with coil; Conductor passes the magnetic conductor that is wound with coil and the alternating voltage that induces becomes the direct voltage that contains ripple by rectification circuit, again by after the holding circuit, and the output direct voltage that son monitoring and indicating equipment use of can powering.
Magnetic conductor of the present invention is annulus, square frame or ellipsoidal structure.
Coil turn on the magnetic conductor of the present invention can be adjusted.
Owing to adopted folder formula coupling, can not disconnect the power transmission line of installation and operation, in the place of needs this clamping power supply is installed very easily, offer relevant electronic monitoring and indicating equipment nearby.Two clips of clamping power supply are connected on the AC transmission line, and the induction energy fetching device becomes electric energy transmitting to rectification circuit into direct current, and follow-up holding circuit can keep the stable of electric power output voltage, and keep power supply in assurance power transmission line power failure a period of time.

Fig. 3 is the difformity structure chart of the magnetic conductor of induction energy fetching device.
Embodiment
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention is further described.
As shown in Figure 1, clamping power supply of the present invention comprises two folder formula couplings 2, conductor 3 and induction energy fetching devices 4.One end of described folder formula coupling 2 links to each other with power transmission line 1, is fixedly clamped, and the other end of two folder formula couplings is connected by conductor 3, and conductor 3 passes the magnetic conductor that is wound with coil in the induction energy fetching apparatus 4.
As shown in Figure 2, the output that is wound with the magnetic conductor 5 of coil links to each other with rectification circuit 6, and the output of rectification circuit links to each other with holding circuit 7, and the output of holding circuit 7 is the VD of clamping power supply.Folder formula coupling 2 and the power transmission line 1 electric UNICOM of going up, on the mechanical structure relative fixed motionless be both mechanical fixation.The shape of magnetic conductor as shown in Figure 2 can be circular, square frame shape or ellipticity as shown in Figure 3.
When having alternating current to flow through on the power transmission line 1, also having electric current in folder formula coupling 2 and the conductor 3 passes through, the magnetic conductor that is wound with coil 5 in the induction energy fetching device can induce corresponding alternating voltage, this alternating voltage becomes the direct voltage that contains ripple by rectification circuit 6, promptly exports the direct voltage of can power son monitoring and indicating equipment use again by holding circuit 7.
Example: when the alternating current on the power transmission line 1 is 600A, the electric current that conductor 3 passes through is 60A, the ac output voltage of the magnetic conductor that is wound with coil 5 in the induction energy fetching device is about 10V, behind circuit such as rectification circuit 6, holding circuit 7, the VD that can offer electronic monitoring and indicating equipment is 5V, and power is about 0.5W.
During use, need the electric current excursion on the consideration power transmission line.According to its excursion, can adjust the coil turn on the magnetic conductor in the induction energy fetching device, assurance can obtain stable voltage output, can not damaged by rush of current excessive on the power transmission line again.
