Aiming at the stress concentration problem existing in the front part of the high-voltage cable joint explosion-proof device, using the finite element simulation method of electric field, temperature field, flow field and displacement field coupling, the design on the bending curvature of the front part of the high-voltage cable joint explosion-proof device is optimized. Based on the three-layer iterative algorithm, the gas flow velocity, pressure distribution and stress value of the inner wall of the cavity are obtained at different times in the explosion-proof cavity. The pressure and stress...
