Description
MNS Low voltage switchgear , Electrical switchgear ,Switchgear cabinet, Switchgear,China low voltage switchgear,LV switchgear
MNS Low-voltage withdraw-able switchgear assembled from modular components from a combination of low voltage switchgear withdraw-able type (hereinafter referred to as the device). This device is suitable for power plants, transformer substation, petrochemical, metallurgy, steel rolling, light industry and textile factories and enterprises, and residential quarters, high-rise buildings and other places, as the AC 50 ~ 60Hz, rated working voltage 660V and below the low voltage power distribution system, power distribution and motor control centers, capacitor compensation, power conversion, distribution and control purposes.
Environmental conditions of switchgear
The ambient air temperature is not higher than +40 °C, not less than -5 °C, and 24h average temperature does not exceed the +35 °C.
Atmospheric conditions: air cleaner, the relative humidity at the highest temperature is +40 °Cless than 50%, at a lower temperature allows a higher relative humidity, for example, 90% at +20 °C, but to take into account the temperature changes, there may occasionally produce moderate condensation.
Altitude of not more than 2000m.
The switchgear's device adapted to these temperatures during transportation and storage: -25 °Cto +55 °Cin the range, in a short time (less than 24h) up to +70 °C, extreme temperatures in these devices should not be subjected to any restore the damage, but also in normal conditions, should be able to work.
If you can not meet the above conditions of use, the user and the manufacturer should be resolved through consultation.
When the unit used in offshore oil drilling platforms and nuclear power plants should be entered into technology agreements.
Features of switchgear
MNS low voltage switchgear system and traditional products, compared with more advantages, its technical level has reached the international advanced level in the nineties.
Compact design: space to accommodate smaller functional units.
Structural versatility, flexible assembly: The 25mm module design, easy to split the cabinet and drawer space to enhance the possibility to meet a variety of structural forms, and the use of environment protection requirements.
Standard modular design of MNS switchgear: can be composed of, respectively, protection, operation, conversion, control, regulation, determination, direction and other standard cell, the user can select any assembly required. More than 200 different kinds of assemblies can form the framework of the program structure and the drawer unit.
