The power supply can ensure that electronic monitors on the transmission lines and indicating equipment can normally work even if current does not exist in the transmission lines because the power supply is not induced by a magnetic field, solves the problems that power is supplied to the electronic monitors on the medium-high voltage transmission lines and the indicating equipment for a long time, overcomes the defects of a magnetic field induction method for acquiring energy, does not influence the normal operation of the transmission lines and has generality.
Description
Technical field
The invention belongs to power technique fields, be specifically related to a kind ofly be applicable to that getting of electrical network mesohigh 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 the 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 owing to Insulation Problems; The powered battery mode that often adopts, its power supply energy can be exhausted in the short period of time, changes very inconvenience, even impossible fully, and the result can cause electronic monitoring and indicating equipment to work.Existing high pressure is got the ability power supply, is to utilize the electric current in the high voltage transmission line to produce magnetic field, and magnetic field induces corresponding electric energy and exports as power supply in the ironcore choke around power transmission line; Its work prerequisite is that high voltage transmission line must have electric current to flow through, and it is the circuit of bringing onto load (being no current) for connecting high pressure but not, and electric energy output then can't be provided.
Summary of the invention
The object of the present invention is to provide a kind of high voltage source, this high voltage source just can guarantee the electronic monitoring and the indicating equipment operate as normal that are equipped with on the power transmission line as long as power transmission line has voltage.
For realizing the object of the invention; Adopt following technical scheme: a kind of power supply that is applicable to the mesohigh power transmission line; Comprise coupling, get ability electrode and induction energy fetching device, described coupling is one or more, and an end of coupling is fixedly connected with power transmission line; The other end can electrode be fixedly linked with getting, the input two ends of said induction energy fetching device respectively with power transmission line with get can the electrode electrical communication.
As the improvement of technique scheme, get between ability electrode and power transmission line and satisfy insulating requirements.Said getting can be circle frame, square frame, rectangle frame or oval frame structure by electrode.
As the further improvement of technique scheme, said induction energy fetching device comprises iron core, rectification circuit and the voltage stabilizing holding circuit that is wound with coil; The output that is wound with the iron core of coil links to each other with rectification circuit, and the output of rectification circuit links to each other with the voltage stabilizing holding circuit, and the output of holding circuit is the VD of power supply.
Owing to adopted coupling, can not break off the power transmission line of installation and operation, in the place of needs this power supply is installed very easily, offer relevant electronic monitoring and indicating equipment nearby.The induction energy fetching device can be integrated with coupling, also can place in the electronic monitoring and indicating equipment of being supplied power.High voltage source according to the invention even there is not electric current in the power transmission line, also can guarantee the electronic monitoring and the indicating equipment operate as normal that are equipped with on the power transmission line because be not through magnetic field induction.Particularly, the present invention has following technique effect:
1. directly therefrom high voltage transmission line power taking has solved electronic monitoring and the long-term problem of supplying power of indicating equipment on the mesohigh power transmission line;
2. joiner structure need not break off power transmission line and install, and does not influence the operate as normal of power transmission line;
3. at high voltage transmission line not under bringing onto load (being no current) and the bringing onto load situation, all can get and can supply high-pressure electronic monitoring and indicating equipment to use from power transmission line, solved the deficiency that the magnetic field induction method is got ability;
4. centering high voltage transmission line, the present invention has versatility.
