本文论述新型轻便式电弧焊变压器的原理和设计计算方法,文中包括两部分内容。第一部分论述两芯柱的弧焊变压器的原理和设计计算方法,文中提出原副两线圈重合率的概念,并证明漏抗和重合率的关系。第二部分论述三芯柱抽头式弧焊变压器的原理和设计计算方法。本文根据理论研究提出新的设计计算方法和公式,经过试制样机,用理论计算所求得的数值与实测数值相当一致。
This article discusses the principle of new portable arc welding transformers and design and calculation methods, including two parts. The first part discusses the principle and design calculation method of arc welding transformers with two legs. The concept of coincidence rate of primary and secondary coils is proposed in this paper, and the relationship between leakage reactance and coincidence rate is proved. The second part discusses the principle and design calculation method of triple-core tapped arc welding transformers. In this paper, a new design and calculation method and formula are put forward based on theoretical research. After trial prototype, the numerical values obtained by theoretical calculation are quite consistent with the measured values.
