This paper introduces theFully sealed inflatable cabinetsThe use of the environment and the difference between the inflatable cabinet and the ordinary ring cabinet. Today, we cite the advantages of inflatable cabinets.

Increase the power supply radius of the medium voltage line.

Improve the power supply quality of medium voltage grid.

Reduce the power loss of the medium voltage grid.

Protection of non-ferrous metals and land resources.

Increase the capacity of the main transformer and improve the power supply capacity of the substation.

Improve the transmission capacity of distribution lines and reduce the number of distribution lines.

Due to these advantages of inflatable cabinets, the use of inflatable cabinets is very extensive. Generally can be used in small two substation, switching substation, Box substation, residential areas, industrial and mining enterprises, large shopping malls and so on.

Usage environment

A. Ambient air temperature: up to 40 degrees Celsius (average 24 hours not exceeding 35 degrees Celsius), minimum-25 degrees Celsius;

B. Elevation: not exceeding 3000 m (in coordination with the manufacturer when more than 3000 m);

C. Air humidity: The average daily relative humidity is not greater than 95%, and the average monthly relative humidity is not greater than 90%.

D. two times the size of the system electromagnetic interference does not exceed 1.6 kv.

Product Features

A. Cabinet structure: The inflatable chamber adopts 3-5mm thick stainless steel plate, the welding robot is welded after machining by CNC machine tool, the welding deformation is small, the air tightness is good. The rest of the compartment adopts high-quality cold-rolled steel plate, which is welded after NC bending, and has the characteristics of high precision and good strength. Each functional unit is a separate module, which is very convenient to assemble. Each sealing chamber of the cabinet has an independent pressure relief channel to maximize personal safety and equipment operation.

B. Applicable standards: GB/T 11022-2011 "Standard general technical conditions for high voltage switchgear and control equipment"; GB/T 3906-2006 "3.6KV-40.5KV AC metal closed switchgear and control equipment";

C. Protection class: IP67 pneumatic isolation; IP4X low pressure cabinet.
