Description
Technical field
The utility model relates to a kind of on-Line Monitor Device of transmission line of electricity, especially the device for monitoring tension of OPGW optical on-line monitoring system.
Background technology
Along with fast development of national economy, how to guarantee the circuit on power system security of operation, more R﹠D institutions and business research problem have been become, because China's electrical network is staggered in length and breadth, it is wide to distribute, some circuit tower bar is crossed over sleet, icing, multiple disaster such as air port is the zone badly, geographical terrain restriction in addition, can't in time reflect on-the-spot real conditions, moreover the northern area of China winter temperature is low excessively, continue longer, to the tower bar, insulator, OPGW optical and wire icing situation can't timely monitors, along with the increase gradually of ice covering thickness, tower bar and the invisible increase of gold utensil additional load, in case real load exceeds the design load of tower bar and gold utensil, gently then cause OPGW optical and transmission line of electricity broken string, heavy then tower.Cause the loss that is difficult to estimate to electric system.
Power supply administration is an icing situation of in time understanding OPGW optical, lead and insulator chain, abominable zone in conditions permit, select heavy icing area, set up artificial weather monitoring station, set up simulation tower bar and lead, when awful weather caused analog conducting wire to freeze, the observation personnel measured ice thickness, and fuzzy circuit icing situation this moment of calculating, for whether needing artificial deicing that one line data is provided.
Calculate the actual track ice thickness with the simulation ice thickness, have following shortcoming:
1, data are inaccurate.In the actual track, each tower span is apart from reaching hundreds of rice, and each tower bar present position height above sea level is also not too consistent, so meteorological condition is also inconsistent, cause in the tower bars at different levels OPGW optical and electric power line ice-covering thickness widely different, the simulation ice covering thickness can only reflect near meteorologic parameter and the ice covering thickness that ground is a bit, can not represent the actual ice thickness of lead between tower bar upper conductor and the tower bar span, if will simulate ice thickness is directly used in and carries out computational analysis in the actual track, the actual ice coating load of gained result and circuit misses by a mile, and whether can only give needs artificial deicing that the information of fuzzy and possible errors is provided.
2, reaction velocity is slow.China's transmission line of electricity is intricate, and distributed pole is wide, and the northern area duration in winter is longer, if set up the weather monitoring station at each heavy icing area, sends special messenger's field monitoring, will expend great amount of manpower and material resources, financial resources.The personal monitoring is the one-point measurement data regularly, and the ice trouble data can't be in time fed back in analytical calculation.
3, directly measuring optical fiber composite overhead ground wire OPGW and powerline ice-covering weight.Tradition icing monitoring can only be by measuring weather station inside conductor cladding thickness, estimation actual motion circuit optical fiber composite overhead ground wire OPGW and transmission line of electricity deadweight and icing weight, can't measuring optical fiber composite overhead ground wire OPGW and lead on true icing weight.
The utility model content
, reaction velocity inaccurate at above-mentioned data be slow, can't carry out the technical matters of timely monitor to OPGW optical and transmission line of electricity, specially proposes following technical scheme:

When transmission line of electricity and OPGW optical bear value of thrust under normal circumstances, on-line monitoring system only shows the weight and the tension value of lead or OPGW optical, during as hazard weathers such as icing or strong wind, will increase the weight of lead or OPGW optical and the change of tension force, at this moment the inner bridge balance of dynamometry strain gauge element can be broken, the signal of output can produce linear change along with the increase and decrease of external load
Be arranged at dynamometry strain gauge element and miniature transmitter in the stressed body sky, obtain working power by aviation plug, data line from higher level's monitoring unit, output signal after will amplifying through built-in miniature transmitter simultaneously is transferred to monitoring unit, realizes the real time on-line monitoring to the weight of lead or OPGW optical.
Compared with prior art, the utlity model has following advantage:
The antijamming capability of 1 the technical program is strong, the measuring accuracy height.Among the circuit of the direct incoming fiber optic composite overhead ground wire of the utility model OPGW, the signal of its output only has relation with the weight change of lead or OPGW optical, and interference load can't add; The assurance measurement data is authentic and valid.The strain gauge element of dynamometry and miniature transmitter are built in stressed body interior, have shielded the interference of extraneous high-voltage electromagnetic field fully.Guaranteed the precision of measuring.
2 the technical program can on-line monitoring, feedback in real time.Get final product the long-term work output signal behind power transmission and transformation line or the OPGW optical on the utility model access tower bar, its output signal changes the variation that presents linearity with external load, can output signal is provided at any time the upper level monitoring unit.
The variation of 3 the utility model energy on-line monitoring OPGW optical weight and stressing conditions thereof, only need during installation the top of the device for monitoring tension of OPGW optical on-line monitoring system is connected with the gold utensil that is connected the tower bar, the suspension clamp of bottom is connected with OPGW optical optical fiber and gets final product.
In the direct incoming fiber optic composite overhead ground wire OPGW ground wire, output signal was only relevant with OPGW optical weight when 4 the utility model used, directly output and the linear signal of load, accuracy height.
The manufactured materials of 5 stressed bodies is a special stainless steel, and this material has acid and alkali-resistance, and is anticorrosive, not corrosion, and endurance, characteristics such as intensity height have improved the reliability of products energy.
