Description
Technical field
The present invention relates to a kind of device that high-voltage transmission line towers structural member generation plastic yield is carried out on-the-spot automatic detection alarm.
Background technology
The visual plant that electric power pylon is carried as electric power, the investment of this equipment accounts for about 40% of circuit gross investment, and the security implication of electric power pylon the safety of whole electrical network.When iron tower bears big wind load, circuit icing, seismic (seismal and breaks load, big plastic yield all can take place in the part of iron tower, these big retrospective distortion tend to cause the iron tower damage even the accident that collapses, and cause huge disaster for national economy and the people's lives and property.Therefore press for now that exploitation is a kind of to be handled iron tower to carrying out in time the device of detection alarm automatically in the plastic yield of labour iron tower timely before damage, loss is dropped to minimum.
Summary of the invention
The automatic detection alarm device solves of electric power pylon structural member provided by the invention plastic yield do not have the online auto monitoring of simple easy maintenance and the technical matters of reporting to the police during existing iron tower of power transmission line structural member generation plastic yield.
The present invention overcomes the above problems by following scheme:
The automatic detection alarm device of electric power pylon structural member plastic yield, the structural member that comprises electric power pylon, magnetic-field test defective display board (1), first row's electrode slice string (2) and second row's electrode slice string (3), the electrode slice number of first row's electrode slice string (2) polyphone equates with the electrode slice number of second row's electrode slice string (3) polyphone, it is characterized in that, described first row's electrode slice string (2) and second is arranged on the dual-side of the parallel respectively correspondence that is arranged on described magnetic-field test defective display board (1) symmetrically of electrode slice string (3), magnetic-field test defective display board (1) is attached on the surface of structural member of electric power pylon, first row's electrode slice string (2) is electrically connected with the base stage of pad pasting transistor (5), the negative electricity of the emitter of pad pasting transistor (5) and power supply (4) links together, the positive pole of power supply (4) and second row's electrode slice string (3) are electrically connected, the collector of one end of alarm lamp (6) and pad pasting transistor (3) is electrically connected, and the positive electrical of the other end of alarm lamp (6) and power supply (4) links together.
The electrode slice of described composition electrode slice string is a scale copper.
The invention solves the on-line monitoring problem of iron tower of power transmission line structural member plastic yield, the magnetic memory that its stress concentrates the position to be taken place when deforming in conjunction with the iron tower structural member changes, can judge the position of electric power pylon generation plastic yield fast and accurately, and then can avoid the iron tower unstability that causes thus to damage, can greatly improve the detection efficiency of iron tower plastic yield.

Embodiment
The automatic detection alarm device of electric power pylon structural member plastic yield, comprise magnetic-field test defective display board, electrode slice string, pad pasting transistor, alarm lamp, power supply, lead, described electrode slice string links to each other with magnetic-field test defective display board, with lead power supply and pad pasting transistor are connected to form the loop, alarm lamp is in parallel with transistor collector and positive source, magnetic-field test defective display board is attached on the structural member of easy generation plastic yield of electric power pylon, and by the power supply stable power-supplying.When the retrospective distortion does not take place in the iron tower structural member, this moment, the inside ferromagnetic powder of magnetic-field test defective display board evenly distributed, its resistance value is very big, make by the trigger current of the electric current in the base stage of power supply, magnetic-field test defective display board and pad pasting transistor and the closed-loop path that emitter is formed less than the pad pasting transistor, make the pad pasting transistor be in cut-off state, at this moment be off state by the emitter of power supply, alarm lamp and pad pasting transistor and the loop that collector is formed, alarm lamp does not work.When iron tower structural member generation retrospective is out of shape, the appropriate section that is attached to the magnetic-field test defective display board on the iron tower generation plastic yield structural member is also followed structural member and is deformed, the magnetic field of the deformation place on the magnetic-field test defective display board is changed, the stray field that forms, ferromagnetic powder on the magnetic-field test defective display board is arranged along deformation direction, cause magnetic-field test defective display board about the circuit resistance that forms between corresponding two electrode slices reduce, make by power supply, electric current in the closed-loop path that the base stage of magnetic-field test defective display board and pad pasting transistor and emitter are formed is greater than the trigger current of pad pasting transistor, make the pad pasting transistor be in conducting state, at this moment by power supply, the loop that the emitter of alarm lamp and pad pasting transistor and collector are formed is an on-state, alarm lamp is lighted, and carries out the distortion of iron tower generation retrospective and reports to the police.
Iron tower structural member plastic yield autoalarm provided by the invention can be in time, exactly light warning is carried out in iron tower generation plastic yield, effectively avoided iron tower to cause the generation of transmission system accident owing to plastic yield.
Be in ground magnetic environment iron tower hardware down under the effect of big load during the generation plastic yield, form area of stress concentration, area of stress concentration has higher stress energy, its inner directed and irreversible rearranging of magnetic domain that can have magnetostriction character, and form the stray field distribution form of similar defective, magnetic in the magnetic-field test defective display board is influenced by stray field to align, and magnetic-field test defective display board is the surface tension principle of the liquid of utilization own just, can make iron powder rest on certain position turning circuit forever.The present invention is simple in structure, uses flexibly, can promptly and accurately monitor the plastic yield of iron tower by the appropriate change shape to adapt to different iron tower structural member situations.
