Abstract

Abstract

International thermonuclear experimental reactor (ITER) poloidal field (PF) converter is a high-power and heavy-current six-pulse converter bridge with rated capacity of 41 MV·A and rated current of 27.5 kA. For such a large rated current, ITER PF converter is designed to consist of 12 thyristor branches in parallel on each bridge arm. In temperature rise test, the temperature of several key parts such as thyristor case, fast fuse, flexible connection and RC loop resistance in the thyristor branch needs to be detected. If the temperature measurement points are arranged in each thyristor branch, there will be hundreds of temperature measurement points, which greatly increases the difficulty of temperature rise test. In order to decrease the temperature measurement points and facilitate the temperature rise test, the test method that the current balance test is performed first to get three thyristor branches with maximum current sharing and then the temperature rise test is performed at that key parts on these three thyristor branches is proposed in this paper. According to Joule's law, the key parts temperature rise of other thyristor branches must satisfy the requirement as long as the temperature rise of that key parts in these three thyristor branches with maximum current sharing satisfies the requirement. This test method simplifies the temperature measurement points from hundreds to dozens, which facilitates the layout of temperature measurement points and the acquisition of temperature data.
