Description

technical field [0001] The invention relates to the detection field of voltage transformers, in particular to an automatic crimping device and a verification method for multi-position high-voltage voltage transformers. Background technique [0002] The voltage transformer error test can only be verified step by step. Among them, transformer calibrator, voltage load box, voltage regulator, booster and standard voltage transformer are used. After manual wiring, use manual voltage regulation or automatic voltage regulation, and then test each test point one by one according to the requirements of the regulations. [0003] It takes about 10-15 minutes to complete the verification of a voltage transformer, and each time a voltage transformer is completed, it needs to be rewired. The maximum daily inspection quantity of voltage transformers in the metrology verification department is 10 to 20 pieces. [0004] The transformer calibrator is the main instrument used to verify the ...

AI Technical Summary

Problems solved by technology

[0005] The existing technology can detect 12 or 16 low-voltage core-through current transformers at a time, but when testing voltage transformers, only one can be detected at a time, and every time one is completed, it needs to be re-wired, and the work efficiency is low. All involve high-pressure operations, and there are certain safety risks

Disadvantages of the original technology: only one can be detected at a time, and the work efficiency is low; each wiring involves high-voltage work, and the safety risk is high; the wiring is cumbersome and complicated, and the efficiency is low

However, the traditional voltage transformer verification method has been difficult to adapt to the existing demand
