MNS 型低壓抽出式開關柜（以下稱開關柜）是我公司參考了國外公司的 MNS 系列低壓開關柜并加以綜合改進后開發(fā)的，是目前國內(nèi)較優(yōu)良的低壓抽出式開關設備。該產(chǎn)品均由標準化的、成系列的模塊組成，并且抽屜具有可靠的機械聯(lián)鎖裝置，使用戶在使用時更安全、更可靠。
本開關柜適用于交流 50(60)Hz、額定工作電壓 400V、660V，額定電流 5000A 及以下三相五線制的電力供電系統(tǒng)，可用于發(fā)電廠、變電所、工礦企業(yè)、大樓賓館、機場、碼頭以及廣播電視等通信中心，來作為發(fā)電、輸配電、電能轉換及電能消耗設備的控制，并通過電容補償柜對其主母線進行無功補償。符合國標準：GB7251.1《低壓成套開關設備》IEC60439《低壓成套開關設備和控制設備》
MNS type low-voltage draw-out switch cabinet (hereinafter referred to as switch cabinet) is developed by our company after referring to the MNS series low-voltage switch cabinet of Company of Switzerland and making comprehensive improvement. It is currently a relatively advanced lowvoltage draw-out switch equipment in China. This product is composed of standardized and series modules, and the drawer has reliable mechanical interlocking device, which makes users safer and more reliable in use.
The switch cabinet is suitable for a three-phase five-wire power supply system with AC 50(60)Hz, rated working voltage 400V, 660V, rated current 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, radio and television and other communication centers to control power generation, transmission and distribution, power conversion and power consumption equipment, and perform reactive power compensation on its main bus through a capacitance compensation cabinet. Comply with national standards: GB7251.1 《Low Voltage Complete Switchgear》 IEC60439 《Low Voltage Complete Switchgear and Control Equipment》
