The Shape Design of Energy Leakage Hole of 220kV High Voltage Cable Explosion-Proof Joint

In view of the lack of optimization design method for the shape design of the venting hole of the 220 KV high-voltage explosion-proof cable joint, this paper uses the finite element calculation method of temperature field, fluid field and displacement field to propose the design principle and method of optimizing the shape of the venting hole. The degree of gas beaming at the venting hole of 220 KV high-voltage explosion-proof cable joints with different opening shapes is calculated, and the shape of the venting hole is round. The design method and key parameters proposed in this paper provide a direction for the optimization design of the energy venting hole of the high-voltage explosion-proof cable joint.
