In the field of power distribution box PC gas engineering project, the control box is a key machine and equipment. Because many electrical equipment must be applied in the whole process of electrical engineering construction to ensure the smooth development of electrical discipline and the safety of constructors. Next, let's take a detailed look at the installation standard of the control box?

When installing the control box, we must master its structure and understand each part of the control box, so as to understand its principle and the problems that must be paid attention to in installation, and promote the control box to achieve an ideal operation state according to the efficacy of each part and the structure of the design scheme.

Secondly, the installation should be carried out according to the engineering drawings and technical standards. Because there are many models and specifications of the control box, the control boxes with different models and specifications have different installation, so we should pay attention to the technical standards. Only according to the strict technical standards can machines and equipment with high use value be installed. However, if the control box is not installed according to the technical standards, the control box of the final design scheme will endanger all normal applications and cannot ensure its safety.

Adoption of maintenance form of distribution box

The maintenance form of bottom voltage distribution box should be adopted according to the standards of the workplace.

（1） In places where the air humidity does not exceed 75% and the risk factors are small, such as dust generation, no corrosive vapor or steam, and no flammable and explosive chemicals, the bottom pressure distribution box can be open.

（2） Maintenance type shall be used in places with air humidity close to 100%, especially in wet and cold places and places with corrosive steam or steam.

（3） For dusty sites that can cause a lot of smoke and dust, anti pollution distribution boxes should be used.

（4） In the H-1 and H-2 fire accident risk sites with flammable liquid, floating and sedimentary flammable smoke and dust or flammable chemical fibers, antifouling type shall be adopted; In the H-3 fire accident risk site with solid combustion, the maintenance type can be selected.

  (5)  Use in sites with explosion risk.
