When do public buildings need a power distribution room?

Large, self-contained building that is needed.

Summary. The transformer room can be a dry-type transformer or an oil-immersed transformer, the high-voltage distribution room can be a high-voltage switchgear, and the low-voltage distribution room can be a low-voltage switchgear.

The transformer room can be a dry-type transformer or an oil-immersed transformer, the high-voltage distribution room can be a high-voltage switchgear, and the low-voltage distribution room can be a low-voltage switchgear.

1. From the perspective of authority, the special power distribution room is managed by the owner; The public distribution room is managed by the power supply bureau. 2. From the perspective of load distribution in the town, the load supplied by the special distribution room is the electricity used by public facilities and equipment in the community, such as fire pumps, life pump, fans, elevators, public lighting and supporting commercial equipment; The load supplied by the public distribution room is exclusively for residents' daily electricity.

What's the problem?

Code for the design of substations of 10kv and below GB50053 94 Chapter 6 Section 2 The requirements for the building are as follows:

Article The high-voltage distribution room should be equipped with natural lighting windows that cannot be opened, and the window sill should not be lower than the outdoor floor; The low-voltage distribution room can be equipped with natural light windows that can be opened. The side facing the street of the distribution room should not be opened. Article 1 The doors of the transformer room, distribution room and capacitor room should be opened outward.

When there is a door between adjacent distribution rooms, the door should be able to open in both directions. Article The doors and windows that are frequently opened in each room of the power distribution station should not be directly connected to the adjacent places with serious acid, alkali, steam, dust and noise. Article 1 Transformer rooms, distribution rooms, capacitor rooms, etc., shall be equipped with facilities to prevent rain, snow, snakes, and rodent animals from entering the room from lighting windows, ventilation windows, doors, cable trenches, etc.

Article The surface of the interior wall of the distribution room, the capacitor room and the auxiliary room should be plastered and whitewashed. The ground (floor) should be calendered with high-grade cement plastering. The ceiling of the distribution room, transformer room, capacitor room and the inner wall of the transformer room should be whitewashed.

Article The length of the distribution room greater than 7m should be provided with two outlets, and should be arranged in the distribution room at the two or distribution end of the missing end. When the length is greater than 60m, it is advisable to add an outlet. When the substation is arranged in a double-storey arrangement, the distribution room located upstairs should have at least one exit to the outdoor platform or passage.

Article The cable interlayer, cable trench and cable room of the power distribution station and the substation shall take waterproof and drainage measures. The prevention and control of leakage in the distribution room should adhere to the principle of multi-channel fortification, combination of elimination and prevention, and comprehensive treatment, and adopt various means such as comprehensive fortification, node sealing, and composite waterproofing.

1. Control the cracks of the wall: Under the current level of construction technology, it is difficult to completely avoid the cracks of the external wall no matter what structural form is adopted. In addition, there are a large number of window holes, door holes, scaffolding holes, reserved pipeline holes, window flute holes and other weak parts on the exterior wall of the distribution room, and special attention is paid to these weak points in the external wall seepage.

In addition, improving the impermeability of wall materials is of great help to the wall impermeability. Reasonable masonry materials are selected for exterior wall masonry, and the gaps between the blocks are plugged to prevent wall leakage caused by infiltration.

2. Strengthen wall drainage: The common practice of strengthening wall drainage is to take water-repellent treatment measures on the external wall. For example, silicone emulsions are used to treat the exterior walls so that they cannot be wetted with water to prevent leakage due to capillary action.

3. Promote new coating film waterproof coatings: With the innovation of waterproof construction technology and the wide application of new exterior wall waterproof materials (such as polymer, polymer modified asphalt, asphalt-based and other different binders composed of coils, coatings and sealing materials, as well as various admixtures used to improve the impermeability and crack resistance of rigid waterproof concrete, it is becoming easier and easier for exterior walls to seepage.

4. Strengthen the maintenance in use: After the completion of the decoration of the building, the use management and maintenance should also be strengthened to avoid the plastering and other structures falling off due to environmental factors such as external impact and frost heave, resulting in the reduction of the anti-leakage ability of the external wall.
