Opening direction of substation building doors
Thread Content
There is a saying that the door located in the middle of the substation building – the door between the high-voltage area and the low-voltage area – should open in the direction of the low-voltage area. I’m not sure which standard or specification this comes from It is only known that GB 50053-2013, the \"Design Code for Substations of 20 kV and Below\", specifies that exterior doors should open outward, while interior doors need to be \"bi-directional spring doors\". There is currently a middle door that opens in only one direction; if it can be ensured to open toward the low-pressure side, the correction will be simpler: lol

Beijing Local Standard DB11/527—2015 4.3.2: Doors between equipment rooms and auxiliary rooms shall open in the direction of the auxiliary rooms. The door between the high-pressure chamber and the low-pressure chamber shall open in the direction of the low-pressure chamber. The middle door of the switchgear room should be a two-way opening door. A similar description can be found in item (23) of 3.2.1 in the Handbook for Industrial and Civil Power Distribution Design (4th edition).

GB 51348-2019 Standard for Electrical Design of Civil Buildings, 4.10.9: The doors of transformer rooms, distribution equipment rooms, and capacitor rooms shall open outward and shall be equipped with locks. When a fire-resistant partition wall is installed between adjacent switchgear rooms, the door in such a partition wall shall be a Class A fire-resistant door that opens towards the low-voltage switchgear room. When the partition wall is installed solely for administrative purposes, the door in it shall be a spring-loaded door made of non-combustible material and capable of opening in both directions.
Thank you to the two kind friends upstairs for their help. Sometimes I remember that there are some guidelines, but due to a lack of professionalism and familiarity with them, it’s difficult to find them; professionals know about them as soon as the topic comes up! Thank you:handshake
