Background
At present, in order to ensure that the centralized verification of the 10kv mutual inductor achieves the production high efficiency, the safety guarantee and the economic maximization, some limitations are generally made on a mutual inductor verification line: when the current transformer calibration table on the transformer calibration line is used for calibrating, 6 transformers are required, and the voltage transformer calibration table is required to be full of 3 transformers. Namely, if the current transformer on the current transformer verification platform is less than 6 transformers, a primary current loop cannot be formed. If the voltage transformer detection platform is not full of 3 transformers, mechanical deformation and compression joint dislocation can be caused, and the test cannot be carried out.
However, in actual production, because the number of the transformers in the transformer verification tasks of different batches is not fixed, the situation that the test cannot be completed due to the fact that the last time of a certain batch of transformer verification tasks is less than 3 or 6 can occur. In order to solve the problem, a spare part completion strategy is generally adopted at present, namely when the number of transformers which are verified in the transformer verification task at the last time is less than 3 or 6, a transformer verification line control system can automatically schedule, fix and store spare part models in a cache area to enter a verification platform for completion. However, this approach has drawbacks: after the spare model is tested for a long time and many times, abrasion of different degrees can exist, so that the detection data of the detection platform is not accurate, and normal detection of a test article is influenced.
