1) High beam: Some design considerations when ceiling height without taking into account the height of the beam. Due to the large room Nanyang distribution substation running record span, sometimes up to about the height of the beam 800mm, so the mention of civil conditions should be considered storey height of the beam. 2) the duty room: Some designs will set up in inaccessible duty room in the corner. This article does not comply with the provisions of Section 4.1.6 of GB50053-94, which states "manned substation, duty room should be set separately. High voltage power distribution room and duty room should be straight or communicated through the channel, duty should direct access to the outdoors or walkway leading to the door, "3) cable channel: Some double layout substation low voltage distribution panel set only high-voltage power distribution room in Nanyang trench bottom and rear panel design the most reasonable, two rows communication between the screen and do not ditch. In order to facilitate future access and adjust the cable lines Nanyang distribution room grounding device should ditch all the main cable and control cable channel are within all connected. Equipment layout in the arrangement of substation equipment, we also present problems, even in violation of the provisions of the mandatory provisions, are only an example as follows: 1) high and low voltage distribution system diagram is inconsistent with the plan. Its manifestations are two types: one is a system diagram with the plan in the cabinet, on the contrary the order screen. When the system diagram is for the cabinet to see the front panel, which is arranged from left to right 1,2,3 ...... n; and in the plan is for the back panel, which is arranged from left to right 1, 2,, 3 ...... n, inevitably backwards. The key is to avoid errors in the system and plan should be for the cabinet, arranged in front of the screen from left to right order. Second, there is a plan on the bus bridge between the double-face arrangement of the power distribution panel, but failed to draw the system diagram. 2) low-voltage distribution screen in front, rear screen channel width does not meet the new regulatory requirements. After the screen sometimes after as Jinju wall 700mm, 1800mm apart only when the drawer Low screen double-face arrangement according to specifications GB50053-94 section 4.2.9 stipulates that the low-voltage distribution in a row before indoor distribution panel screen layout, screen The minimum width of the channel: After its screen channel, fixed and drawer are 1000mm; its screen before passage, fixed single row arranged to 1500mm, arranged in a single row drawer 1800mm, double-face arranged fixed 2000mm, Drawer double face arranged 2300mm. Only when the building wall in case of local projections class column, the protruding portion of the channel width can be reduced by 200mm.
