Abstract：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.

Key words：substation;door;two‑way swing door;gas fire extinguishing system;mechanical lock;access control;door closer;cabinet length

摘　要：梳理变电所门的主要作用和设置要点；介绍变电所门的常见的“机械锁”和“门禁”两种形式的管理方式；结合气体灭火系统的特点，分别对两种管理方式下变电所的外门和相邻变电所之间双向开启弹簧门的特点进行分析，提出一种验证灭火剂喷射时能否顶开变电所门的公式，并结合气体灭火系统的要求提出合理建议；最后，分析低压柜长度对门设置的影响并提出建议。

关键词：变电所；门；双向开启弹簧门；气体灭火系统；机械锁；门禁；闭门器；机柜长度
