从理论角度考虑铁心各部分的夹紧力应均匀相 等，而实际制造中铁心上、下轭夹紧力是否与心柱夹紧力相同， 超高压变压器的大型铁心在生产过程中 各工序下实际夹紧力变化情况如何， 变压器在运行 现场的最终夹紧力是否满足要求等等问题， 都需要 在工艺工作中不断探索和完善。
From the theoretical point of view, the clamping force of each part of the iron core should be even and equal, but whether the clamping force of the upper and lower yoke of the actual manufacturing iron core is the same as that of the core column, how the actual clamping force changes in the production process of the large-scale iron core of the UHV Transformer in each process, and whether the final clamping force of the transformer in the operation site meets the requirements, etc., all need to be worked in the process Continuously explore and improve.
生产过程中对铁心绑扎恒压过程压力是否稳 定， 千斤顶的压力转换为聚酯带的收紧力是否保持不变，铁心经煤油气相干燥后夹紧力有无变化，器身 压紧时夹件受力作用下铁心和铁轭夹紧力变化情况 一一进行了确认。
During the production process, whether the pressure during the process of iron core binding and constant pressure is stable, whether the tightening force of the jack converted to polyester tape remains unchanged, whether the clamping force of the iron core changes after kerosene gas phase drying, and whether the clamping force of the iron core and iron yoke changes under the force of the clamp during the pressing of the body are confirmed one by one.
