Abstract
The invention specifically relates to a fault indicator which is installed on a power transmission line and can carry out indication at a fault position. The objective of the invention lies in providing a power transmission line fault indicator, and the indicator can timely provide a standby power supply when abnormality happens to the obtaining of induced electric energy. The indicator comprises a power management module, and the power management module is connected with a microprocessor and an induction electricity-obtaining coil, and is also connected with a rechargeable battery and a solar cell panel. The induction electricity-obtaining coil is connected with the rechargeable battery. The microprocessor is connected with a photosensitive sensor for detecting the brightness of light. The whole indicator continuously work through the rechargeable battery and the solar cell panel under the condition that the induction electricity-obtaining coil cannot carry out normal obtaining of electricity after a fault happens. When light is detected to be sufficient, the indicator can directly obtain power for work through the solar cell panel, and the induction electricity-obtaining coil charges the rechargeable battery, so as to store the electric energy.
Description
Technical field
The invention belongs to fault monitoring field, being specifically related to a kind of for being arranged on transmission line of electricity, and can carry out in abort situation the fault detector that indicates.
Background technology
Transmission Lines distance, branch line are many, in reticulate texture, when being short-circuited, the fault such as ground connection time, troubleshooting is very difficult, and the time of searching is long.Fault detector energy Real-Time Monitoring line current of the prior art, voltage (to earth electric field) and conductor temperature, accurately detect simultaneously and judge that line short, ground connection, disconnection fault are uploaded in time, and monitoring device oneself provides board turning and flashing light instruction.Operation power personnel can be helped to understand the electric current of each monitoring point on circuit, voltage and temperature variations in real time, sound and light alarm is provided after the fault such as short circuit, ground connection appears in circuit, inform that dispatcher carries out operated from a distance with isolated fault and transfer power supply, notice operation power personnel rush towards rapidly scene and process.
At present, the power supply of fault detector comes from the electric energy of inducting being arranged on induction electricity taking coil on cable and producing, can cause like this outside cannot power taking or power taking deficiency time fault detector lost efficacy.
Summary of the invention
The object of this invention is to provide a kind of transmission line malfunction indicator, when electric energy power taking of inducting is abnormal, standby power supply can be provided in time.
For achieving the above object, the technical solution adopted in the present invention is: a kind of transmission line malfunction indicator, comprise power management module, described power management module is connected to microprocessor and induction electricity taking coil, and described power management module is also connected to rechargeable battery, solar panel; Described induction electricity taking coil is connected with described rechargeable battery; Described microprocessor is connected with the light sensor for detecting light intensity.
Preferably, described microprocessor is connected with the A/D data acquisition module for detecting power line current, voltage.
Preferably, described microprocessor is connected with wireless RF communication module, and described wireless RF communication module carries out two-way communication by the wireless RF communication module of 433M frequency range and adjacent fault detector.
Preferably, described microprocessor is connected with clock module.
The present invention has following beneficial effect: respond to after breaking down electricity taking coil can not correctly power taking when, whole fault detector will be worked on by rechargeable battery or solar panel, and the information broken down can be passed, the concrete time that fault occurs can also be passed out simultaneously; After data acquisition center receives the failure message that fault detector beams back, the very first time fail result can be reported to the police, remind operation power managerial personnel to process in time; The failure message that fault detector is beamed back comprises electric current, the correlation parameter such as magnitude of voltage and time of failure of the physical fault circuit that microprocessor calculates, data acquisition center shows to all failure messages passed back, for next step process action of operation power managerial personnel provides foundation.After fault handling completes, board turning reset operation can be carried out by data acquisition center to fault detector, make it reenter normal detected state.
