っていた。A low-order picture stone vibration is generated in the name of the sender, and the result is NjJk
Conventionally, in the so-called Carrotsbing test, the power transmission line is vibrated using a vibrator fixed on the ground. However, with this conventional method, it is virtually impossible to conduct a test by mounting an exciter on a transmission line that is actually suspended due to the height of the transmission line. Therefore, we had no choice but to conduct tests using bench tests.
本発明の目的は、実際に架線されている送電線にギヤロ

成したことにある。The present invention is characterized by attaching a force vibrator capable of generating a predetermined inertial force in conjunction with the vibration of the actuator to a spacer provided on the power transmission line to be tested.
The vibration of the actuator of the exciter is controlled by a servo mechanism, and the peak value of the acceleration of the power transmission line is fed back to the waveform generator that generates the operation signal for the servo mechanism. The reason is that it is designed to encourage people.
以下、図面に従って不発明の実施セ１ｊを説明する。Hereinafter, the embodiment 1j of the invention will be explained according to the drawings.

The UOm device 1 is installed approximately at the center of the two ends of the power transmission line 2 at the crossing points 3, 3'. This is because it is more efficient to provide a stress point at the antinode of the amplitude when the power transmission line resonates.

are doing. Therefore, when the actuator 11 of the vibrator 1 is vibrated, the weight fixed to the frame vibrates and a predetermined inertial force is generated, which acts on the power transmission lines 2 through the spacer 4.

The displacement of the actuator of the vibrator 1 supplied from the above is detected by the displacement generator 23 and the displacement amplifier 24, and is fed back to the input signal of the servo amplifier 22 to form a servo mechanism. The inertial force generated by the vibrator 1 acts on the power transmission line and excites it, and the vibration acceleration of the power transmission line is detected by the acceleration detector 25 and the acceleration amplifier 26 and output to the peak detection circuit 27. ing. The peak detection port w1127 detects the peak value of the detected acceleration value and supplies it to the comparison circuit 28. Comparison episode F@
28 is also inputted with an acceleration constant value which is a target value for adding/subtracting the feed tS, and the comparator circuit 28 supplies an operating signal to the waveform generator 29 from this target value and the heak detection value. The waveform generator 29 outputs all the waveforms according to the operating signal and supplies them to the servo amplifier 22.

This is action explanation 1 showing the inertial force generated due to the persistent seismic position and sagging, and the vibration displacement of the power transmission line. The waveform outputted from the waveform generator 29 and caused by the displacement ε2L of the exciter 1 is a triangular wave so that the inertial force generated from the exciter 1 acts near the maximum amplitude of the power transmission line. A substantially pulse-like inertial force is generated by this triangular wave-like displacement of the edge vibrator 1, and when this period is made to match the natural frequency of the power transmission line, the transmission line is excited in a resonant state. The peak value of the vibration acceleration of this power transmission line waves and is transmitted to the generator 29, so
Send! The edge is controlled to vibrate at the desired acceleration.

た１、In addition, in the above-mentioned embodiment, when one vibrator is fixed in one direction and vibrated, two vibrators are attached and vibrated. The vibration direction may be controlled by controlling the phase amount of the vibration in the axial direction, or the posture of a single vibration exciter is usually controlled by a motor, etc. I put the sword Ll in the spacer for a while so that I can do it.
The copying direction may be controlled.
