Calibration table body for full-inspection receiving test of high-voltage transformer

Abstract

The invention discloses a calibration table body for a full-inspection receiving test of a high-voltage transformer, and the calibration table body comprises an aluminum profile frame and a transformer calibration station body. A mutual inductor verification station body is composed of a mutual inductor conveying unit, a withstand voltage test station, a voltage transformer induction withstand voltage and error test station, a current error test station and a functional module, and the mutual inductor verification station body is installed below an aluminum profile frame. The calibration tablebody is compatible with various mutual inductors, and manufacturers are different due to different transformation ratios of different mutual inductors. The appearance sizes of the mutual inductors are various, the table body can carry out adaptive wiring on the mutual inductors according to the mutual inductors with different sizes, so that the calibration requirements of the different mutual inductors are met, multiple test items can be carried out, the device can carry out all items of full-inspection test calibration on the high-voltage voltage and current mutual inductors after arrival ofgoods, and the mutual inductor calibration efficiency is high. The calibration table body is suitable for calibrating the high-voltage transformer.

AI Technical Summary

Problems solved by technology

At present, the verification methods of high-voltage transformers are mostly manual verification, the verification efficiency is low, the management and control methods are backward, and the learning cost of the verification personnel is high, and a safe and effective centralized integrated control scheme has not been formed.

[0003] In the current industry, the high-voltage transformer verification devices generally have problems such as single function, separate sets of various test items, and incomplete equipment configuration functions, resulting in many high-voltage transformer verification institutions not having complete high-voltage transformer inspection and verification capabilities.

During the test, it is necessary to carry out manual handling between different testing equipment, which will inevitably increase equipment purchase costs and labor costs

At the same time, switching between different tests requires manual disconnection of the wiring repeatedly, which will inevitably increase the test error rate caused by wiring deviation while the verification efficiency is low.

In addition, due to manual operation, the learning cost of manually learning the verification operation specification is relatively high. It is necessary to learn two kinds of transformers, 10 kinds of tests and up to 15 times of wiring methods.
