摘要
为深入研究高压隔爆型电缆连接器的载流量和事故多发原因,以LBG1-200/6高压电缆连接器为研究对象,从电、绝缘、热3方面分析连接器的结构及材料属性;运用有限元方法,建立了高压电缆连接器的电磁场与热场耦合模型,分析了运行在恶劣环境下高压电缆连接器的温度分布云图。算例定量分析了电力谐波、绝缘老化及结构微变引起的额外温升及载流量变化,为矿用电缆连接器的安全使用提供依据。
To understand the ampacity and the accident causes of flame-proof high-voltage cable connectors, LBG 1- 200/6 high voltage cable connector is taken as an example. The structure and material of the connector are introduced from the aspects of electrical, insulation and thermal properties. A coupling model of electromagnetic field and thermal field of the cable connector is established via the finite element method to obtain and analyze the temperature distributions in different atrocious environments. And the additional temperature rise and ampacity change, which are caused by power harmonic, dielectric loss and slight structure change, are quantitatively analyzed by way of example. This study may benefit safe application of the mining cable connector.
