The utility model content

The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, detect laborsaving, use easily, reading easily, control is used for the torsional forces on-line measuring device of high voltage isolator easily.

For solving the problems of the technologies described above, the utility model by the following technical solutions.

A kind of torsional forces on-line measuring device that is used for high voltage isolator, it is characterized in that: it comprises insulator, torque sensor, sensing data line, moment of torsion display and is installed in the operating mechanism of high voltage isolator and the moment of torsion transmission bar assembly between the operator lock, described moment of torsion transmits between bar assembly and the operator lock and links to each other by insulator, and described torque sensor is fixed in moment of torsion and transmits on the bar assembly and pass through the sensing data line and link to each other with the moment of torsion display.

As further improvement of the utility model:

Described moment of torsion transmits the bar assembly and comprises fork, universal joint lower fork, long pass torsion bar and short pass torsion bar on the universal joint that links to each other successively, an end of pitching on the described universal joint links to each other with insulator, the other end of pitching on the universal joint links to each other with an end of universal joint lower fork with central block by trundle, the other end of described universal joint lower fork links to each other with the long pass torsion bar, the other end of long pass torsion bar links to each other with the short pass torsion bar, and described torque sensor is installed between long pass torsion bar and the short pass torsion bar.

Compared with prior art, advantage of the present utility model just is:

1,, detects labour intensity and significantly reduce by electric power operating mechanism actuating disconnector;

2, the detected value digitizing shows, and is convenient to reading, is convenient to record, and has reduced the possibility of mistake;

3, the setting by in advance, peak value that can recording operation moment, instantaneous value, and its upper and lower limit that whether exceeds the product setting judged, in case overproof, get final product alarm;

4, this detector can be embedded in the total line transfer of assembling of disconnector fully by the specialization design, accomplishes the online in real time monitoring.Measurement data can be uploaded to computer by interface, becomes M curve after software processes, and analysis and judgement is very convenient;

5, the utility model can show the operation moment of torsion of electric power operating mechanism drive disconnector separating brake (or combined floodgate) rapidly.By peak value, instantaneous value, higher limit, the lower limit that different parameters can show and write down the operational torque in separating brake (or combined floodgate) process easily is set, if the overshoot value can be reported to the police.Its precision is very high, can reach ± 0.5N.m.For the ease of understanding the moment characteristics in the whole operation process, detect data and can be uploaded to computer, the mode with M curve shows after treatment, very intuitively analysis and judgement.
