    MNS低壓抽出式開關柜特點

    Characteristics of the MNS Low Voltage Draw Out Switchgear

    ★設計緊湊:以較小的空間能容納較多的功能單元,節省柜體體積,

    MCC柜最多可安裝36個8E/4抽屜或9個8E抽屜,抽屜單元具有體積小、功能強、導向準確、互換性極強的特點,適合安裝三極或四極空氣開關,并具有可靠的機械聯鎖,功能單元的有效安裝高度為1800mm,在同一柜體中可自由組合成固定式和抽屜式二種形式,

    ★結構通用性強,組裝靈活:以25 mm為摸數的C型型材能滿足各種結構形式、防護等級及使用環境的要求,

    ★采用標準模塊設計:分別可組成保護、操作、轉換、控制、調節、測定、指示等標準單元,用戶可根據需要任意選用組裝。以200余種組裝件可以組成不同方案的柜架結構和抽屜單元,

    ★安全性:大量采用高強度阻燃型工程塑料組件,有效地加強了防護安全性能,

    ★垂直母線通道采用分斷式功能板.直角L型分支母線嵌裝在其中,

    ★MCC柜可背靠背排列,

    ★裝配方便:不需要特殊復雜工具。


    Compact Design: More functional units can be accommodated in a smaller space, saving the volume of the cabinets. 36 pcs of 8E/4 drawers or 9 pcs of 8E drawers at least can be installed in MCC cabinet. The drawer unit is characterized by its small volume, strong function, accurate orientation and strong interchangeability, suitable for installation of three-pole or four-pole air switch which has reliable mechanical interlock. The effective installation height of the functional unit is 1800 mm. It can form the solid type and drawer type freely in the same switch cabinet.


    Strong structure universality, and flexibly assembly: C-profile sectional materials with 25mm as modulus can meet the requirements of various structural forms, protection levels and operational environment.


    Use of standard modular design: It can respectively constitute for the protection, operation, conversion, control, regulation, measuring, indication and other standard units. The user can select the assembly arbitrarily according to the needs. More than 200 assembling parts can constitute frame structures and drawer units of various programs.


    Safety: A large number of high-strength flame-retardant engineering plastics components are used, which effectively enhances the performance of the protective security.


    The vertical bus channel adopts breaking functional board in which the right angle L type branch bus is inserted.


    The MCC cabinets can be arranged back to back.


    Easy assembly: No special complicated tools are required.
