Explosion-proof distribution box installation requirements
Explosion-proof distribution box installation requirements
First, the explosion-proof distribution box circuit installation path requirements:
(1) The path of the main circuit 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, avoid the hidden dangers of 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 hazardous materials such as explosive and flammable materials: Wide storage space and places where corrosive gases, liquids, and contamination are severe.
Third, explosion-proof double emergency lights should avoid the following places
(1) Places obstructing traffic or obstructing the sight of Wentong:
(2) The railway road was taken from the slope of the land and roadbed.
3) Underground pipes, underground channels, power cables, communication cables and other underground facilities are buried.
(4) Buildings, tunnel exits, and vehicular traffic are frequently subject to collisions.
(5) Near the river bank, the water period, the sand, the marshland and the spring pool.
Fourth, the pole height and depth requirements
(1) The height of the pole should be determined according to the geographic installation position, the depth of the pole, the arc of the box, and the vertical safety distance from the conductor to the ground (by the object). The explosion-proof double-headed emergency light can be determined by using our electric safety formula. Calculations.
