MNS type-Shenzhen Junan Electrical Equipment Co., Ltd

Product Details

Use

◆ MNS-type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) In order to meet the needs of the development of the power industry,
with reference to foreign MNS series of low-voltage switchgear design and to improve the development of high-level low-voltage switchgear
◆ The product conforms to the national standard GB7251, VDE660 and ZBK36001-89 "low pressure extraction type switchgear", the international standard
IEC439 stipulates MNS type low voltage switch cabinet adapts various power supply, the power distribution need
◆ can be widely used in power plants, substations, industrial and mining enterprises, building hotels, municipal construction
and other low-voltage power distribution system.

Structure Features

◆ MNS low-voltage switchgear frame for the modular structure, the basic skeleton from the C-type steel assembly. All the structural parts
of the cabinet are galvanized
◆ The self-tapping locking screw or the 8.8 grade hex bolts are firmly connected to the basic cabinet, and the components such as doors, partitions,
mounting brackets and bus function units corresponding to the program changes are assembled into a complete switchgear
◆ switch cabinet internal dimensions, parts size, compartment size are in accordance with the modular (E = 25mm) changes
◆ Each of the MNS modular low-voltage switchgear cabinets is divided into three chambers, namely the horizontal bus room (at the rear of the cabinet),
the drawer compartment (in front of the cabinet), the cable room (in the lower part of the cabinet or the right side of the cabinet)
◆ between the room and the room with steel or high-strength flame-retardant plastic function board separated from each other, between the upper
and lower drawers with ventilation holes in the metal plate isolation, in order to effectively prevent the switching element due to failure caused
by arcing or bus and other lines Short circuit caused by the accident
◆ MNS-type low-voltage switchgear structure designed to meet a variety of options:
◆ compact design: a small space to accommodate more functional units
◆ structural parts of the strong, flexible assembly to E = 25mm for the modulus, structure and extraction unit can be any combination
to meet the needs of system design
◆ Bus with high-strength flame retardant, high insulation strength of the plastic function board protection, with anti-fault arc performance,
so that the operation and maintenance of safe and reliable
◆ The size of the drawer of the mechanical interlocking institutions meet the standard requirements, there are connections, testing,
separation of three distinct locations, safe and reliable
◆ Standard module design: can be composed of protection, operation, conversion, control, regulation, measurement, instructions and other standard units,
according to the requirements of any assembly
◆ The use of high-strength flame-retardant engineering plastics, effectively enhance the protective safety performance.
