Description

technical field [0001] The invention belongs to the technical field of transformer detection, and in particular relates to a verification system and a verification method of a fully automatic induction voltage divider. Background technique [0002] The inductive voltage divider is a voltage ratio standard developed in the 1950s. Its internal structure determines that the inductive voltage divider has a very high measurement accuracy, generally 10 -5 ~10 -6 , commonly used in precision electrical measurement. [0003] The traditional inductive voltage divider is operated with a dial-type knob, and the following problems mainly exist in the measurement process: [0004] (1) The dial-type knob structure requires manual operations such as value selection, wiring, and wiring changes. The process is cumbersome and easy to wear and tear the equipment. [0005] (2) When using the inductive voltage divider for self-calibration or mutual calibration, the excessive voltage ratio ma...

Problems solved by technology

[0004] (1) The dial-type knob structure requires manual operations such as value selection, wiring, and line modification, which is cumbersome and easy to wear and tear the equipment

[0005] (2) When using the induction voltage divider for self-calibration or mutual calibration, the excessive voltage ratio makes it impossible to verify many transformation ratios one by one in the actual verification, and most of the time only random inspection can be carried out

[0006] (3) The measurement results of the traditional inductive voltage divider need to be manually recorded and entered into the computer for calculation, which is a huge workload and prone to errors

[0007] In view of the above situation, in order to solve the problems of cumbersome operation, huge workload and low work efficiency in the verification process of the traditional inductive voltage divider, according to the working principle of the inductive voltage divider, the digital control circuit is designed and designed under the premise of ensuring the accuracy requirements. An automatic control induction voltage divider measurement system, realizing voltage regulator output, self-calibration and mutual calibration, data acquisition and calculation
