Abstract
The invention relates to a high voltage power transmission line indicator comprising an inductor (1), a rectifying circuit (2), a filtering circuit (3), a voltage stabilizing circuit (4), and an indication circuit (5). The high voltage power transmission line indicator is characterized in that the inductor (1) is the non-inductive line string; and a state indication device is used to indicate whether the power transmission of the high voltage line is normal. When the faults such as interphase short circuit, interphase grounding, and switch trip-out of the high voltage power transmission line occurs, the power failure accident of the high voltage power transmission line can occur, and after the power failure, the turning-off indication can be transmitted by the state indication device, and the faulted part can be determined accurately according to the light illumination indication, and therefore the line inspection and maintenance of the inspection personnel can be facilitated.
Description
Technical field
The present invention relates to electric power application. specifically, time relate to ultra-high-tension power transmission line duty instruction.
Background technology
Whether power high voltage power transmission line positioning indicator is a kind of for being arranged on overhead transmission line ultra-high-tension power transmission line, for indicating on high-tension line at the device of normal transmission electric energy.When ultra-high-tension power transmission line generation phase fault, mutually indirectly, open and trip time ultra-high-tension power transmission line will product power-off fault, after power failure, positioning indicator will produce instruction of turning off the light, by luminescence instruction can accurate failure judgement position so that circuit is overhauled, safeguards by patrol officer in time.
Existing electric power line fault indicator has the disadvantages that
1. fault detector adopts battery to power mostly, and battery life is short, it is necessary to periodic replacement.
2. likely because of battery premature failure so that equipment failure, can not correctly indicate the normal operating conditions of transmission line of electricity.
Summary of the invention
For overcoming existing shortcoming, the present invention proposes following a kind of new scheme.
A kind of high voltage transmission line positioning indicator is provided, described a kind of high voltage transmission line positioning indicator includes induction apparatus (1), rectification circuit (2), filter circuit (3), mu balanced circuit (4), indicating circuit (5), it is characterised in that described induction apparatus (1) is noninductive line river.
Further illustrate, described induction apparatus (1) is made up of L1 and R1 connecting for line of induction river, rectification circuit (2) is piled BG1 by bridge and is formed, the two ends in line of induction river are connected with two inputs of rectification circuit (2) respectively, two outfans of rectifier bridge stack after being connected with the two ends of filter circuit (3) again with mu balanced circuit (4)) two inputs be connected, mu balanced circuit (4) is made up of IC1, DC voltage after voltage stabilizing is connected with indicating circuit (5), and indicating circuit (5) is made up of R2 and D1 series winding.
Further illustrating, induction apparatus (1) can also be thoughts line river.
Accompanying drawing explanation
Fig. 1 is principles of the invention block diagram.
Fig. 2 is the circuit theory diagrams of the present invention.
Detailed description of the invention
Below in conjunction with embodiment and compare accompanying drawing the present invention is described in further detail.
A kind of high voltage transmission line positioning indicator as shown in Figure 1, including the induction apparatus (1) being sequentially connected electrically, current rectifying and wave filtering circuit (2), current limiting pressure-limiting circuit (3), mu balanced circuit (4), accumulator (5).
The ac voltage signal that line of induction river senses through high voltage transmission line enters rectifier bridge stack BG1 rectification after R1 pressure limiting, mu balanced circuit IC1 is entered after the filtered electric capacity C1 filtering of DC voltage after rectification, burning voltage input after voltage stabilizing is to indicating circuit, and the light emitting diode D1 in indicating circuit provides continuous continual duty instruction overall process.
Of the present invention basic circuit principle and principal character and advantages of the present invention have more than been shown and described.
