Description ：
MNS LV withdrawable switchgear (hereinafter referred to as device) is manufactured by standard module through consulting MNS series low voltage switch cabinet of Switzerland ABB Company, and synthetically improved. The device is applicable to the system with AC 50Hz, rated working voltage 660V and below, used as control device for various power generation, transmission, distribution, power transfer and power consumption device.
It is widely used in low voltage distribution system of various mining enterprise, tall building and h otel, municipal construction etc. Besides the general land use, after special disposal, it also can be used for marine petrol drill taken platform and nuclear power station. The device accords with international standard IEC439-1 and national standard GB7251.1.
Main feature :
Compact design: Contain more function units with less space.
Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structure and type, protection grade and operating environment.
Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication etc such standard units. User can choose assembly according to requirement at will. Cabinet structure and drawer unit can be formed with more than 200 components.
Fine security: Adopt high strength antiflaming type engineering plastic pack in large quantity to effectively enhance the protective safety performance.
High technical performance: Main parameters reach the advanced level at home.
Main technical parameters:
Conditions for normal operating environment：
Ambient air temperature: -5℃ ~+40℃ and the average temperature should not exceed +35℃ in 24h.
Air condition: With clean air. Relative humidity should not exceed 50% at +40℃ . Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually.
Altitude above sea level should not exceed 2000M.
The device is suitable to the transportation and store with following temperature :-25℃ ~+55℃ , in short time (within 24h) it reaches +70℃ . Under the limiting temperature, device should not suffer damage that can' t recover, and it can works normally under normal conditions.
If the above operating conditions not meet user's demand. Consult with manufactory.
Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.
