    摘 要:隨著電力電纜的廣泛應用,接頭防護失效引發(fā)電弧爆炸事故顯著增加。針對高壓電纜接頭保護裝置的安全失效問題,給出了短路電弧沖擊下的防爆優(yōu)化設計;根據泄能孔不同尺寸仿真設計新型中間接頭保護結構,并建立基于等效爆源方法的多物理場仿真模型,來優(yōu)化防爆盒結構參數與泄能效率。仿真結果表明,改進后的中間接頭保護裝置顯著降低了爆炸沖擊波的威脅,具有更好的實用性和高效性。

    Abstract: With the widespread application of power cables, the failure of joint protection has led to a significant increase in arc explosion accidents.This paper focuses on the explosion-proof optimization design under short-circuit arc impact in order to solve the safety failure problem of high-voltage cable joint protection devices. According to the different sizes of the energy dissipation holes, a new type of intermediate joint protection structure is simulated and designed, and a multi-physical field simulation model based on the equivalent explosion source method is established to optimize the structural parameters and energy dissipation efficiency of the explosion-proof box. The simulation results show that the improved intermediate joint protection device significantly reduces the threat of explosion shock waves and has better practicability and efficiency.
    Key words: cable joint; multi-physics field coupling; joint protection device; energy dissipation hole; arc impact; explosion-proof box
