摘要

为研究利用热水实现电力设备除冰

对热水除冰过程水射流特性进行了研究

拍摄观测了水射流结构

开展了不同影响因素下的水射流温度空间分布试验以及击打力试验

最后进行了热水射流除冰和泄漏电流试验。研究结果表明:随着出口压强增大

水射流温度小幅度降低

环境风速对水射流温度的影响大于环境温度

水射流温度随喷嘴直径增大而升高;水射流击打力随出口压强和喷嘴直径增大近似呈线性增长

击打力下降程度随着角度增大而增大;热水射流可以作为电力设备的一种除冰介质

除冰时间与热水初始温度、出口压强、覆冰质量等多个因素相关;通过水射流的泄漏电流受距离、喷嘴直径和出口压强综合影响。

Abstract

In order to study the use of hot water to achieve deicing of power equipment

the characteristics of water jet during hot water deicing were studied. The structure was photographed and observed. The temperature spatial distribution test and impact force test of water jet under different influencing factors were carried out. Finally

the experiments of hot water jet deicing and leakage current were carried out. The research results indicate that

as the outlet pressure increases

the temperature of the water jet decreases slightly. The effect of the ambient wind speed on the water jet temperature is greater than that of ambient temperature. The temperature of the water jet increases as the nozzle diameter increases. The impact force increases approximately linearly with the increase of the outlet pressure and the nozzle diameter. The decrease degree of the impact force increases as the angle increases. The hot water jet can be used as a deicing medium for power equipment. The deicing time is related with the initial temperature of hot water

outlet pressure

ice weight and so on. The leakage current through the water jet is comprehensively affected by the distance

nozzle diameter

and outlet pressure.
