Background
When a high-voltage test of an ultra-high voltage and extra-high voltage alternating current-direct current transformer and a reactor is carried out, often, because the test voltage level of a test article is too high, a voltage-equalizing ring or a voltage-equalizing cover needs to be added on a wire outlet terminal of the test article to meet the test requirement. For the convenience of the test, the voltage is generally equalized in a form of an equalizing ring. The existing equalizing ring installation sequence is as follows: 1. dismantling the transformer wiring terminal; 2. sleeving the grading ring on a transformer outlet terminal; 3. and then the transformer wiring terminal is arranged on the outlet terminal for compressing. However, when test wiring is carried out, the grading ring of the transformer is easy to loosen, wiring is difficult, interference and other problems are easy to occur in the test process, and meanwhile, certain potential safety hazards also exist. In order to reduce the wiring difficulty, improve the production efficiency and ensure the smooth running of the transformer test, a novel ultra-high voltage and extra-high voltage transformer wiring terminal is urgently needed to be designed to meet the installation of a grading ring.
