摘要

高压开关设备的温升试验对保障电力系统安全运行至关重要。针对传统高压开关温升试验耗时长、能耗高和安全隐患等问题，文中提出了基于热时间常数的温升稳定值预测方法以优化试验效率。首先，介绍了热时间常数理论及计算方法，给出了温升曲线方程，提出了可利用最小二乘法拟合温升曲线以获取相关参数。然后，通过对GW12kV户外隔离开关、GW40.5kV户外隔离开关和ZW32-12/630A户外柱上开关进行试验验证，结果表明该方法预测结果偏差在±3K内。最后，提出了预热试验优化策略，文中所选3种开关温升试验时间分别缩短约36.2%、45.2%、41.4%，能耗分别降低了31.1%、40.0%、33.8%，有效提升了试验效率和能效，为优化高压开关温升试验提供了可行的策略。

Abstract

The temperature-rise test of high-voltage switchgear is crucial for ensuring safe operation of power system. As for such issues as long duration of temperature rise test

high energy consumption and potential safety hazards of traditional high voltage switcgear

a prediction method of temperature-rise stable value based on the thermal time constant is proposed in this paper so to optimize the test efficiency. Firstly

the theory and calculation method of the thermal time constant are introduced

the temperature-rise curve equation is given

and the least square method is porposed to fit the temperature-rise curve so to obtain relevant parameters. Then

the method is verified through tests on type GW12kV outdoor disconnector

type GW40.5kV outdoor disconnector and type ZW32-12/630A outdoor polemounted switch. The results show that the prediction error of this method is within±3 K. Finally

the pre-heating testing optimization strategy is proposed. The test time of temperature-rise test of the three types of switchgear selected in this paper is shortened by approximately 36.2%

45.2%

and 41.4% respectively

and the energy consumption is reduced by 31.1%

40.0%

and 33.8% respectively

. which effectively improve the test and energy efficiency and provide a feasible strategy for the temperature-rise test of high-voltage switchgear.
