有關變頻器驅動電動機中浪涌對策的基礎研究

摘要：變頻驅動的電動機，為滿足節能及小型化、高性能化等市場需求，必然要面對嚴酷的使用條件，其中，變頻器產生的浪涌（surge）對電動機絕緣系統會產生不利影響�！懊麟姟惫�司在掌握變頻器浪涌對電機影響的同時，使用了耐局部放電性能優越的漆包線。針對該絕緣系統的適用性進行了不斷的探索研究。 敘詞：絕緣系統 變頻器浪涌 局部放電 耐局部放電的漆包線 V-t特性 變頻器 Abstract：TO meet the market needs of energy saving, being smaller and high performance, the transduction-driven electromotor has to face severe conditions, among which, surge resulting from transducers will lead to disadvantageous effect on the insulation system of the electromotor. Mingdian Company applies enamelled copper wire, which enjoys excellent perfornance of enduring partial discharge, to prevent the effect to electromotor resulting from transducer surge; in the meantime, the company provides constant research on the applicability of the insulation system.
