摘要
配电变压器(DTs)被认为是电网的基础和高价设备,其故障会影响电网的可靠性。DTs运行的连续性在很大程度上取决于其绝缘条件和随后的热斑温度(HST)。通过考虑散热能力的有效电气和机械参数,提出了一种用于预测DT的HST的新公式。
Distribution transformers(DTs)are considered to be the basic and expensive equipment of the power grid,and their failure will affect the reliability of the power grid.The continuity of the operation of DTs is highly dependent on their insulation conditions and the subsequent Hot Spot Temperature(HST).In this paper,a new formula for predicting the HST of DT is proposed by considering the effective electrical and mechanical parameters of heat dissipation capacity.
