摘　　要：在变压器短路电动力的计算中,目前是以静态力代替动态力的方法来进行的。这不能适应变压器机械强度的要求。针对此问题,从电动力的基本理论出发,建立起变压器的动态数学模型,对变压器在短路电流作用下线圈产生的动态力进行了理论分析和计算,对在短路电流作用下的变压器线圈(器身)绝缘结构进行了初步研究,提出了动稳定的计算方法。The calculation of transformer's electrodynamic forces during short - circuiting is done with substitution of static state force for dynamic state force till now. It cannot satisfy the requirement for mechanical strength of the transformer. Aiming at this problem and based upon the fundamental theory of electrodynamic force,the dynamic state mathematic model for transformers is created. Theoretical analysis and calculation of dynamic state forces produced by coils in the transformer under short - circuit action are made. Primary study of insulation structure for transformer coils(trans. body)under action of short - circuit current is made,and the calculation method of dynamic stability is submitted.
