摘要

根据污闪事故发生时的环境监测数据

大气环境污染及其污染性质也是影响输变电设备外绝缘表面污秽程度的因素

而污染物粒径较小的地区积污增长速度较大。因此

针对某些学者提出的理论盐密值与大气环境参数间的经验公式

提出了纳入PM

2.5

后的经验公式修正建议。分别根据纳入PM

2.5

的经验公式和未纳入PM

2.5

的经验公式

计算了理论盐密值

并与安装在监测点附近的光传感器盐密在线监测装置的实测数据进行了对比分析。利用纳入PM

2.5

后的经验公式的ESDD理论计算值与实际值较为吻合

而未纳入PM

2.5

的ESDD理论计算值与实际测量结果差异率较大。在可实时获取大气环境参数的地区

可以考虑利用纳入PM

2.5

后的经验公式推算该地区的理论盐密值的实时变化情况

及时掌握该地区电网污秽等级的变化。

Abstract

A lot of environmental monitoring data when the contamination flashover accident happened show that

the contamination condition on power transmission equipment insulation surface is related to atmospheric pollution

pollution growth rate is larger in the area with smaller pollutant particle size. In this paper

the empirical formula power between equivalent salt deposit density（ESDD）and atmosphere environment parameter by some domestic research institutions is introduced. The modified empirical formula is given

in which PM

2.5

is considered. The academic ESDD is calculated by the empirical formula wi

th and without the consideration of the PM

2.5

respectively.The compare of the measured data of ESDD by on-line monitoring device based on optical sensing technology to the calculated results shows they are in good agreement when using the empirical formula with the consideration of PM

2.5

but the calculated results have larger difference when using the empirical formula without the consideration of PM

2.5

. This means

in some areas there is no pollution monitoring device or unavailable measurement of ESDD

the empirical formula with consideration of PM

2.5

can be used to calculate the academic ESDD and its change in real time

which can reflect the change of gird pollution level in this area timely.
