    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
