1. When the length of the high-voltage power distribution room exceeds 7m, two doors should be installed, and should be arranged at both ends
The porting door of GG-1A switchgear is 1.5m wide and 2.5~28m high.
2. The recommended size of the operation channel of the fixed switchgear is 2m for a single row arrangement and 2.5m for a double row arrangement from the panel surface. When the number of switch cabinets is large, the channel width can be increased appropriately.
3. In the high-voltage power distribution room, generally only high-voltage switch cabinets are installed. When the number of cabinets is small (such as four or less), they can also be arranged in the same room as the low-voltage power distribution panel, but not
It should be arranged face to face, and the clear distance between the single-row arrangement and the low-voltage power distribution panel should not be less than 2m.
4 When the wire is overhead, the minimum height from the outlet bushing to the outdoor ground is 4m, and the distance from the hanging point of the outlet to the ground is generally not less than 4.5m. The height of the high-voltage power distribution room should be based on the It depends on the height difference between the inner and outer ground and the above-mentioned distance. The headroom height is generally 4.2~4.5m.
5 There should be a slope and a sump at the bottom of the indoor power cable ditch to facilitate temporary drainage, and the ditch cover should be made of patterned steel plates. The maintenance pits under adjacent switch cabinets should be separated by brick walls.
6. For the power distribution device that supplies power to the primary load, a fireproof partition or a partition wall with a door opening should be provided at the bus section.
