Abstract
The invention discloses a resonant electromagnetic induction energy collecting circuit, a potential difference electric field energy collecting circuit and a ultra-capacitor energy storage circuit, which aim to the problems (short service life, unreliable action, difficulty in information remote transmission internetworking caused by small power) caused by the requirement of installing a battery in the conventional electric power line fault indicator. The power supply problem of all circuits in the fault indicator hanging in the sky and equipotential with the high-voltage line is solved radically. Since the fault indicator has sufficient energy, the indicator is additionally provided with an enhanced programmable wireless digital transmission module; the hanging height of more than 10 meters of the indicator is sufficiently utilized; under the condition of the same transmission power, the communication distance is greatly increased, the setting of most relay stations is reduced and even exempted, the cost of the wireless networking remote transmission information is decreased.
Description
Technical field
The present invention relates to a kind of electric power line fault indicator, especially a kind of passive electric line-failure indicator and information remote transmitting system thereof.
Background technology
Under the prior art condition; when power circuit generation phase fault or little electric current singlephase earth fault; because the distribution line branch line is numerous; the protective relaying device of dress can only inform that fault has taken place circuit that certain switch is had jurisdiction in the transformer station; concrete trouble spot occurs on that branch line, that root electric pole, can only rely on manual patrol.Therefore concrete trouble spot can not in time be found, be the difficult problem that electric system exists for a long time.
For the concrete trouble spot of accurate response, electric power line fault indicator must provide indicator signal (phase fault and single-phase low current grounding) to two big class faults of distribution line, this just requires each root branch line of power circuit all should mount indicator, since indicator be unsettled mount and with the voltage equipotential of high-tension line, and be just motionless for many years once mounting, the indicator internal circuit is by installing powered battery, because outdoor environment is abominable, do not wait equipment to put into operation, battery just damages, because the power issue of indicator can't solve, the information remote transmitting networking is more difficult, and why Here it is has the main cause that electric power line fault indicator can't be applied now.
Main contents of the present invention
Content of the present invention is at the essential problem that battery caused (the life-span weak point of installing in the existing indicator; It is unreliable to move; Because of the little information remote transmitting networking of power is had any problem), " resonant mode electromagnetic induction energy collecting circuit ", " potential difference (PD) formula electric field energy collecting circuit " and " super capacitor energy-storage circuit " have been designed, fundamentally solved and be suspended in powerup issue aerial and inner each circuit of the equipotential fault detector of hi-line, accomplished real " passive " structure.
Because fault detector has had the sufficient energy, " enhancement mode programmable radio digital transmission module " installed in the present invention additional in indicator, made full use of indicator mounting highly more than 10 meters, under the situation of same emissive power, increased communication distance greatly, reduce even exempt the setting of most relay stations, the cost of wireless networking teletransmission information is reduced.
