Application scope of MNS low voltage drawer cabinet
MNS low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is an advanced low-voltage switchgear designed and improved with reference to foreign MNS series low-voltage switchgear to meet the needs of the development of power industry. Zbk36001-89 low voltage withdrawable switchgear, the international standard iec439 stipulates that MNS low voltage switchgear can meet various power supply and distribution needs and can be widely used in low-voltage distribution systems such as power plants, substations, industrial and mining enterprises, buildings, hotels and municipal construction.
Structural features of MNS low voltage drawer cabinet
The frame of MNS low-voltage drawer cabinet is a combined structure, and the basic frame is assembled from C-shaped steel. All structural parts of the cabinet frame are galvanized and firmly connected with the basic cabinet frame through self tapping locking screws or grade 8.8 hexagon bolts. Into a complete switchgear. The internal dimension, element dimension and compartment dimension of the switch cabinet vary according to modularization (E = 25mm).
The structural design of MNS low-voltage drawer cabinet can meet the requirements of various incoming and outgoing line schemes: top in and top out, top in and bottom out, bottom in and top out, bottom in and bottom out.
Compact design: more functional units in smaller space.
The structural parts have strong universality and flexible assembly. Taking e = 25mm as the modulus, the structure and extraction unit can be combined arbitrarily to meet the needs of system design.
The bus is protected by high-strength flame retardant and high insulation strength plastic functional board, which has fault arc resistance and safe and reliable operation and maintenance.
The mechanical interlocking mechanism of drawers of various sizes meets the standard and has three obvious positions of connection, test and separation, which is safe and reliable.
Adopt standard module design: it can form standard units such as protection, operation, conversion, control, adjustment, measurement and indication, which can be assembled arbitrarily according to requirements.
High strength flame retardant engineering plastics are used to effectively enhance the protection and safety performance.
High degree of generalization, standardization and easy assembly. With reliable quality assurance.
This is the relevant content of the application scope and structural characteristics of MNS low-voltage drawer cabinet. In addition, the equipment cabinet can choose different protection levels according to different requirements of working environment, and the continuity and reliability of protection are excellent.
