Owing between iron core and coil and high voltage power transmission bus, high voltage bearing insulating material not being set, whole coil and power consumption equipment are also earth-free, be in vacant state, power supply and power consumption equipment just are in the equipotential state with high voltage transmission line naturally, be used for the induction power taking on ultra-high-tension power transmission line, provide safety low-pressure stability and high efficiency power supply for being arranged at the equipment such as monitoring on ultra-high-tension power transmission line, monitoring, communication.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the rectification circuit schematic diagram.
Embodiment
As shown in Figure 1, two annular iron cores of semicircle consist of between 101, two end faces of an annulus and leave air gap 103, on be wound with that get can coil 102, transmission of electricity bus 104 passes from the circle ring iron core that 2 semi-annular shape iron cores form.When the transmission of electricity bus has alternating current to flow through, to get and can induce voltage in coil, this voltage is done power supply can for low power communication, supervising device through rectifying and voltage-stabilizing and use.
Semicircle annular core, phase cross sectional shape can be oval and circular, and the area of section scope is 20mm
2-50000mm
2, the cross section inside diameter ranges is 10mm-100mm, its material adopts the nano microcrystalline ferromagnetic material.The more traditional silicon steel magnetic of this material volume and weight material significantly reduces, and has solved burning voltage output in normally startup under low current, large curent change scope.
Two semicircle iron cores, during installation, end face keeps the air gap of 0.2mm-3mm, makes it be difficult for entering the magnetic saturation state.
Getting on the iron core can coil 102, and its material adopts copper cash or aluminum steel, and its number of turn scope is the 100-20000 circle, and its wire range is 0.2-5mm.
As Fig. 2, get can coil 102 back meet rectifier bridge and the super capacitor C1 that is formed by D1, D2, D3, D4.The super capacitor charging is compared with battery and be need not special charging control circuit, the life-span is long, reliability is high.Can also the communication of guarantee phase and control circuit work even its energy storage effect transmission of electricity bus short time has a power failure
Owing between iron core and coil and high voltage power transmission bus, high voltage bearing insulating material not being set, whole coil and power consumption equipment are all earth-free, are in vacant state, and power supply and power consumption equipment just are in the equipotential state with high voltage transmission line naturally.
Adopt nano microcrystalline ferromagnetic core material, pass through the isoparametric Proper Match of structure, umber of turn, gas length and control circuit to coil, get can power supply have fundamentally avoided foremost getting can the coil degree of depth saturated, need not generally to adopt as existing document the state of control circuit regulating winding work, make back-end circuit obviously simplify, improved reliability; And monitoring is got energy electric supply installation and high pressure equipotential with communicating by letter, then communicates by letter with optical fiber or wireless mode, making power supply and high-tension room insulation become very simple.Adopt the DC-DC module Charge Management of high conversion efficiency to be combined with ultracapacitor, reduce the electric energy loss of power circuit, satisfy high-power power supply of moment, and power supply can satisfy long-time without the dead band continued power during circuit short time power failure.But self-protection under short circuit and impulse current, and the long-term work energy consumption is low.Thereby effectively solved the power supply problem of the monitoring of intelligent micro-grid system isolated island remote high-voltage line outage and high voltage circuit breaker switch state, communication electronic equipment.
