MNS低壓抽屜式開關(guan) 櫃是采用鋼板製成封閉外殼，進出線回路的電器元件都安裝在可抽出的抽屜中，構成能完成某一類供電任務的功能單元。功能單元與(yu) 母線或電纜之間，用接地的金屬板或塑料製成的功能板隔開，形成母線、功能單元和電纜三個(ge) 區域。每個(ge) 功能單元之間也有隔離措施。抽屜式開關(guan) 櫃有較高的可靠性、防護性和互換性，是比較好的開關(guan) 櫃，目前生產(chan) 的開關(guan) 櫃，多數是抽屜式開關(guan) 櫃。那麽(me) MNS低壓抽屜櫃使用條件有哪些呢？下麵我們(men) 來了解一下吧。

The MNS low-voltage drawer type switchgear is made of steel plate and enclosed in a shell. The electrical components of the incoming and outgoing circuits are installed in withdrawable drawers, forming a functional unit that can complete a certain type of power supply task. The functional unit is separated from the busbar or cable by a grounded metal plate or plastic functional plate, forming three areas: busbar, functional unit, and cable. There are also isolation measures between each functional unit. Drawer type switchgear has high reliability, protection, and interchangeability, making it a relatively good switchgear. Currently, most of the switchgear produced is drawer type switchgear. So what are the usage conditions for MNS low-voltage drawer cabinets? Let's take a look below.

　　MNS低壓抽屜式開關(guan) 櫃適用於(yu) 交流50(60)Hz、額定工作電壓400V、660V,額定電流5000A及以下三相五線製的電力供電係統，可用於(yu) 發電廠、變電所、工礦企業(ye) 、大樓賓館、機場、碼頭以及廣播電視等通信點，來作為(wei) 發電、輸配電、電能轉換及電能消耗設備的控製， 並通過電容補償(chang) 櫃對其主母線進行無功補償(chang) 。符合國標準：GB7251.1《低壓成套開關(guan) 設備》IEC60439《低壓成套開關(guan) 設備和控製設備》。

MNS low-voltage drawer type switchgear is suitable for three-phase five wire power supply systems with AC frequency of 50 (60) Hz, rated working voltage of 400V, 660V, rated current of 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, and broadcasting and television communication points to control power generation, transmission and distribution, energy conversion, and energy consumption equipment, and to compensate for reactive power on its main busbar through capacitor compensation cabinets. Complies with national standards: GB7251.1 "Low voltage switchgear" IEC60439 "Low voltage switchgear and control equipment".

　　正常使用條件：

Normal usage conditions:

　　1、周圍空氣溫度不高於(yu) +40℃,不低於(yu) -5℃,並且24h內(nei) 其平均溫度不高於(yu) +35℃。

1. The ambient air temperature shall not exceed+40 ℃, not be lower than -5 ℃, and its average temperature shall not exceed+35 ℃ within 24 hours.

　　2、周圍空氣相對濕度在溫度為(wei) +40℃時不超過50%，在較低溫度時有較高的相對濕度，如+20℃時為(wei) 90%,但考慮到由於(yu) 溫度的變化有可能會(hui) 偶然產(chan) 生適度的凝露。

2. The relative humidity of the surrounding air does not exceed 50% at a temperature of+40 ℃, and there is a higher relative humidity at lower temperatures, such as 90% at+20 ℃. However, considering the possibility of occasional moderate condensation due to temperature changes.

　　3、戶內(nei) 使用，使用地點的海抜高度不得超過2000米。

3. For indoor use, the sea level at the location of use shall not exceed 2000 meters.

　　4、應安裝在無劇烈震動和衝(chong) 擊，以及不使用電器元件受到腐蝕的場所。

4. It should be installed in a place without severe vibration and impact, as well as in a place where electrical components are not corroded.
