Site explosion-proof distribution box installation specification

First, the explosion-proof distribution box line installation path requirements:

(1) The path of the main line of the explosion-proof distribution box should be as short as possible. The topography and landform are not complicated and the investment is less.

(2) Minimize the occupation of farmland and avoid the hidden dangers of the geological disasters such as depression, easy flushing, ground subsidence, and unstable slopes. Avoid places that are easily touched by vehicles;

(3) Avoid place of production and storage of hazardous materials such as explosive and flammable materials.

(4) As far as possible, the electric circuit of the explosion-proof distribution box shall be set up in a place convenient for traffic to facilitate the operation and maintenance of the construction road.

(5) Path selection should not only take into account the importance of the house, but also consider the future development of urban planning and power grid planning, but also leave a certain width for future development.

Second, explosion-proof distribution box circuit should avoid the following places

(1) The national memorial hall, monuments and similar sites benefit planning area.

(2) House yards, places where trees are clustered;

(3) Flood hazards, floods, unsusceptible areas with hidden mountains, lakes, and unstable geological hazards.

(4) Inflammability of explosive and flammable hazardous materials: Wide storage space and places where corrosive gases, liquids, and contamination are severely produced.

Third, explosion-proof distribution box applicable explosive gas environment:

(1) Zone 1 and Zone 2 hazardous locations.

(2) Type IIA, IIB, IIC, explosive gas environments with temperature groups T1-T4.
