Installation requirements

Explosion proof distribution box, as the name suggests, is a type of distribution box with explosion-proof performance, mainly suitable for petroleum, chemical

In fields such as mining, there are many varieties available now, but sparks are inevitably generated in the studio, so it is important to understand their scope of application.

1、 Requirements for installation path of explosion-proof distribution box circuit:

(1) The main circuit of the explosion-proof distribution box should choose shortcuts as much as possible, with less complex terrain and less investment.

(2) Minimize the occupation of farmland and avoid geological hazards such as depressions, easily eroded land, ground subsidence, unstable slopes, etc. Avoid places that are easily touched by vehicles;

(3) Avoid production and storage areas with explosive and flammable hazardous materials.

(4) Try to install the electrical wiring of the explosion-proof distribution box in a location with convenient transportation to facilitate the operation and maintenance of the construction road.

(5) Path selection should take into account the importance of the house We also need to consider urban planning and power grid planning for future development, and leave a certain margin for future development.

2、 The explosion-proof distribution box circuit should avoid the following places

(1) National memorial halls, monuments, and similar places are planned areas.

(2) Houses, courtyards, and places with dense forests;

(3) There are many mountain floods and water disasters Difficult to pass mountains, rivers, lakes, and geological hazard prone areas with unstable foundations.

(4) The hazards of explosive, flammable and other hazardous materials: widely stored in places and places where corrosive gases, liquids and pollutants are produced.
