Abstract

The invention relates to a quantum current transformer. The quantum current transformer is characterized by comprising a quantum sensor and a quantum measurement module, wherein the quantum sensor and the quantum measurement module are connected through an optical fiber to form a loop. The NV color center has the characteristics of high sensitivity and high frequency response of magnetic measurement, so that the current can be measured in a continuous wave magnetic side environment; the high-sensitivity magnetic sensor can accurately measure current signals in a power grid, so that high-precision current amplitude and phase information is obtained, and the high-sensitivity magnetic sensor is of great significance to operation management of the power grid. Secondly, the magnetic sensor with a high frequency response range can monitor the distribution of high-frequency impact signals in the power grid, the safety state of the power grid is monitored while the current of the power grid is measured, and the safety of the power grid is enhanced.

Description

technical field [0001] The invention relates to the technical field of current mutual inductance, in particular to a quantum current transformer. Background technique [0002] With the continuous expansion of the scale of the power grid, the requirements of the power grid system for the safety, reliability and versatility of the equipment used are also increasing. Taking the current transformer of the power grid system as an example, the traditional electromagnetic current transformer uses the principle of electromagnetic induction to measure the current intensity. It has been continuously improved and optimized in long-term practice, and has made great contributions to social development. However, with the increase of the grid scale and the improvement of technical indicators, the electromagnetic transformer technology gradually shows the bottleneck of various technical indicators, such as small measurement bandwidth, narrow dynamic range, large volume, high energy loss and...
