摘　　要：提出了一种变压器冷却器防尘装置的设计方法,该方法基于电场强度、粉尘粒子荷电量和防尘效率三个目标,建立了优化模型,进而求解得到防尘装置最优集尘极电压。通过在冷却器防尘网后加装防尘装置,利用电防尘原理,可以有效提高滤除效果,该装置主要包括集尘极、电晕极、框架和电源箱4个部分。详细给出了防尘装置集尘极电压设计步骤,并在特高压变压器的工程实践验证了所提方法的有效性。A design method of dust-proof device for transformer cooler is proposed. Based on the three objectives of electric field intensity, dust particle charge and dust-proof efficiency, an optimization model is established, and then the optimal collector voltage of the dust-proof device is obtained. By installing a dust-proof device behind the dust-proof net of the cooler and adopting electric dust-proof principle, the filtering efficiency can be effectively improved. The device mainly includes four parts of dust collecting electrode, corona electrode, frame and power box. The design procedure of dust collector voltage is given in detail, and the effectiveness of the proposed method is verified in the engineering practice of UHV Transformer.
