MNS Series LV Withdrawable Power Electric Switchgear
Products Overviews
MNS LV complete set switchgear is improved and developed by our company on basis of original MNS LV complete set switchgear in accordance with environmental condition of nuclear power plant and meet the requirement of IE class LV switchgear of nuclear power plant. It is applied onlow voltage power distribution of nuclear power plant, lower voltage load and other important facilities of power supply and control. MNS possess functions of 380/220V electric energy distribution, system supervising protection and power facility or equipment control and protection functions under normal and abnormal condition of nuclear power plant, and can maintain above integrity safety functions under design basis event within service life of installation.
MNS is a whole assembling type structure. Its basic framework is assembled by C type material. All stand column of framework is used with C type material mixed structure, with joint between top and bottom of framework connected with strengthen plate. Diagonal brace will be increased at bus room outside at the rear of switchgear to enhance seismic resistance ability of MNS. Framework is of precise size, stable structure and flexible assembly. Whole framework of MNS and parts in switchgear are processed with aluminum zinc coated steel sheet or fine quality cold roll steel sheet(Parts proceeded by cold roll steel sheet should be passivated).All door plate and closing plate are proceed to static spaying by dacromat technology with uniform coating and strong adhesion.
Parameters
Features
1. Compact structure of equipment: with smaller space to accommodate more functional units, unit set of switchgear can accommodate as many as 36 pieces of 8E/4 drawer units.
2. Strong Structural popularity and flexible assembly: C type material meets different kinds of structural forms, requirement of protection degree and service environment.
