Abstract
Description
Technical Field
[0001] The present application relates to the field of detection technology, and more specifically, to a current transformer wiring inspection device. Background Art
[0002] A current transformer is an electrical device based on the principle of electromagnetic induction. Its function is to convert a large current on the primary side into a small current on the secondary side for the purpose of measuring and protecting the safety of the circuit. The core structure of a current transformer includes a closed iron core and a winding. The primary winding has fewer turns and is usually directly connected in series in the circuit being measured, and is consistent with the working current of the entire circuit. This means that almost all the current on the primary side passes through this winding. Due to the large current and the small number of turns of the winding, the primary side can withstand a higher current load.
[0003] On the secondary side, the current transformer has more winding turns, and the secondary winding is connected to the measuring instrument and protection device. During operation, the secondary circuit of the current transformer always remains closed, which is very important because it ensures the low impedance state of the current transformer during measurement. The impedance of the secondary winding and the measuring instrument in series is very small, making the working state of the current transformer close to the short-circuit state, thereby ensuring the accuracy and stability of the measurement.
[0004] Current transformers usually calculate key parameters such as error and ratio by measuring the output current and voltage. This direct measurement method is simple, intuitive and easy for maintenance personnel to use. However, the accuracy of this measurement method is easily affected by many factors, especially the accuracy of the measuring instrument and errors in human operation. For example, insufficient sensitivity or improper calibration of the instrument will lead to deviations in the measurement results. In addition, the skill level and experience of the operator are also potential factors affecting accuracy. In practical applications, additional protective measures and calibration methods are required to ensure the measurement accuracy of the current transformer.
