为解决传统高压输电线路电热融冰速率慢的问题,研究电热融冰技术。在明确高压输电线路电热融冰原理的基础上,确定高压输电线路电热融冰损耗热量,计算高压输电线路电热融冰电流,补偿高压输电线路电热融冰功率因数,接入高压输电线路电热融冰电源,实现高压输电线路电热融冰。设计实例分析结果表明,设计的技术融冰速率明显高于对照组,能够解决传统高压输电线路电热融冰速率慢的问题。
To solve the problem of the slow rate of electric heating ice melting in traditional high-voltage transmission lines,the electric ice melting technology is studied.On the basis of clarifying the principle of electric heating ice melting on high-voltage transmission lines,the heat loss of electric ice melting on high-voltage transmission lines is determined.The electric ice melting current of high-voltage transmission lines is calculated,the power factor of high-voltage transmission lines electric ice melting is compensated,and the high-voltage transmission line electric ice melting power source is connected to realize the electric ice melting of high-voltage transmission lines.The design case analysis shows that the designed technology has a significantly higher ice melting rate than the control group,which can solve the problem of slow ice melting rate of traditional high voltage transmission lines.
