Description

Technical Field

[0001] The present application relates to the technical field of electric energy meter detection. Specifically, it relates to a wireless optoelectronic sampler, its adjustment bracket, and a wireless optoelectronic sampling system. Background Art

[0002] In the field of power metering, the accurate measurement of electric energy meters is a key link to ensure the fairness of power transactions and the stable operation of the power grid. As an important supporting device for the optical pulse sampling and calibration of electric energy meters, the optoelectronic sampler undertakes the task of accurately sampling the optical pulse signals output by the electric energy meters, and thus provides basic data support for subsequent calculation of electric energy errors. The traditional optoelectronic sampler and the electric energy meter calibration device are mainly connected by wired means, that is, the collected pulse signals are transmitted to the electric energy meter calibration device through a cable for processing. Although this wired method ensures the stability of data transmission to a certain extent, it also has many limitations.

[0003] First of all, the cable will increase the equipment cost, occupy space, and greatly limit the deployment location and mobility of the optoelectronic sampler. In the case of needing to measure electric energy at multiple locations or the on-site conditions change frequently, the limitations of wired connection are particularly obvious, which will reduce work efficiency and flexibility.

[0004] Secondly, the wired optoelectronic sampler is easily affected by electromagnetic interference during signal transmission. The electromagnetic field may be coupled into the signal transmission path of the optoelectronic sampler through the cable, resulting in a decrease in signal quality, and even causing mis-sampling or data loss, affecting the accuracy of electric energy measurement.

[0005] Finally, the maintenance cost of the wired optoelectronic sampler is also relatively high. Due to the long-term use of the cable, it is easily affected by factors such as wear and aging, so regular inspections and maintenance are required.

[0006] Currently, the installation methods of the optoelectronic samplers of domestic on-site electric energy meter calibrators include suction cup type, tripping type, magnet type, etc. However, during on-site use, the tripping method cannot be installed when the installation distance on both sides of the electric energy meter is small, and the test installation is time-consuming and laborious; although the suction cup type overcomes the disadvantages of the tripping method, the observation surface is small during test installation, and it is not easy for the optoelectronic sampler to align with the light. Moreover, the window glass of the electric energy meter usually has a lot of dust. When the window glass of the electric energy meter is not clean, the suction cup often falls off due to insufficient suction, and cannot fully meet the test requirements of the on-site electric energy meter calibrator; the bracket type is the most commonly used method at present, and it can be firmly clamped on the electric energy meter to be tested. However, the existing installation bracket of the bracket type optoelectronic sampler is large in volume, not convenient for storage, and cannot be applied to various models of electric energy meters.
