A Brief Analysis of the Key Points of Design of Substation Door
The main functions and key points of setting of substation door are sorted out;two common management modes of substation door,namely,"mechanical lock"and"access control",are introduced;based on the characteristics of gas fire extinguishing system,the characteristics of exterior door of substation and two-way swing door between adjacent substations under two management modes are analyzed respectively;a formula is proposed to verify whether the sprayed extinguishing agent can push the substation door open,and reasonable suggestions are proposed according to the requirements of gas fire extinguishing system;finally,the influence of the length of low-voltage cabinet on substation door is analyzed and suggestions are put forward.
