Description
Technical Field
The application relates to the technical field of photoelectric transformers, in particular to a method and a device for testing local vibration of an optical transformer based on a piezoelectric ceramic principle.
Background
The basic operation process of an optical mutual inductor (FOCT) based on the piezoelectric ceramic principle is shown in figure 1. An LED light source in the electronic cabinet emits a light signal to be transmitted along a single-mode optical fiber, a polarizer generates a path of linear polarized light signal to be transmitted along a polarization-maintaining optical fiber, a tail fiber of the polarizer is welded with a next section of optical fiber at an angle of 45 degrees, and the linear polarized light is orthogonally decomposed into two beams of vertical polarized light when entering the next section of polarization-maintaining optical fiber. When the two beams of light in the vertical mode pass through the 1/4 wave plate, the two beams of light become left-handed circularly polarized light and right-handed circularly polarized light respectively (the optical effect of the 1/4 wave plate), and enter the sensing optical fiber. Because the magnetic field generated by the measured current forms Faraday magneto-optical effect in the sensing optical fiber, two beams of circularly polarized light are transmitted at different speeds, and phase difference is generated. After two beams of optical signals rotate around the conductor for N circles, a reflector is arranged at the end point of the optical fiber to reflect the optical signals back, the polarization direction is also reversed (left-handed rotation is changed into right-handed rotation, right-handed rotation is changed into left-handed rotation), the optical signals pass through the sensing optical fiber again to interact with a magnetic field generated by current, and the acceleration and deceleration effects are doubled due to the reversal. The two beams of light pass through the 1/4 wave plate again and are restored to linearly polarized light, and interference occurs at the polarizer. The phase difference is detected by measuring the interference light intensity through the optical detector, and the phase difference is in direct proportion to the current flowing through the primary conductor, so that the magnitude of the measured current is obtained.
In practical conditions, when a small section of optical fiber in an FOCT optical path is affected by vibration, two optical signals generate a nonreciprocal phase angle in a round-trip optical path
The phase angle
Will be at a phase angle with Faraday
Superimposed on each other, introduces a non-reciprocal phase error, as shown in fig. 2.
The relationship of the nonreciprocal phase angle to vibration is as follows:
in the formula, LB、lpThe beat length and the length of the optical fiber are interfered by vibration; tau is0Time delay from the interference position to the reflector; vbIn order to be the amplitude of the vibration,
representing variation of beat length with vibration;
representing the variation of the vibration with time.
As can be known from the formula (1), the error caused by vibration is related to the length of the optical fiber interfered by vibration, the time delay from the interference position to the reflector, the vibration amplitude and the vibration acceleration; in addition, when external vibration affects the phase modulator, the modulation coefficient and thus the modulation depth are affected
Modulation depth
The demodulation sensitivity of the transformer is determined, and the accuracy of the transformer is further influenced.
To examine the effect of vibration on FOCT, the national standard GB/T20840.6-2017 transformer part 6: supplementary general technical requirements for low power transformers specify vibration testing of FOCT primary components. According to the standard test requirements, the whole FOCT is vertically fixed on a vibration table, vibration of a specified level is applied, the error change of the FOCT is inspected before and after the test, and the state output of the FOCT is monitored in the test process. However, the FOCT based on the piezoelectric ceramic principle is generally used in a higher voltage level, the length of the insulator may be more than ten meters, and a general vibration test bed cannot meet the requirement of overall vibration, so an equivalent alternative test method needs to be found to examine the performance influence of vibration on the FOCT based on the piezoelectric ceramic principle.

In the light CT vertical state, vibration is applied to the front side of the modulation box through a vibration exciter. 5 vibration sensors are respectively arranged on 5 surfaces of the modulation box, a fault recorder is adopted to continuously monitor the secondary output of the light CT, and simultaneously, the vibration values collected by the vibration sensors are monitored.
1) Fixed vibration acceleration, varying vibration frequency
a) Acceleration of 10m/s2The FOCT output versus applied vibration frequency is shown in FIG. 5. The FOCT error current values are large around 1800Hz and 2700Hz, and the maximum value is 1353A.
