MNS低壓抽屜式開關(guān)柜是采用鋼板制成封閉外殼，進(jìn)出線回路的電器元件都安裝在可抽出的抽屜中，構(gòu)成能完成某一類供電任務(wù)的功能單元。功能單元與母線或電纜之間，用接地的金屬板或塑料制成的功能板隔開，形成母線、功能單元和電纜三個區(qū)域。每個功能單元之間也有隔離措施。抽屜式開關(guān)柜有較高的可靠性、防護(hù)性和互換性，是比較好的開關(guān)柜，目前生產(chǎn)的開關(guān)柜，多數(shù)是抽屜式開關(guān)柜。那么MNS低壓抽屜柜使用條件有哪些呢？

MNS low-voltage drawer type switch cabinet is made of steel plate with a closed enclosure. The electrical components of the incoming and outgoing circuits are installed in withdrawable drawers, forming a functional unit capable of completing a certain type of power supply task. The functional unit is separated from the bus or cable by a grounded metal plate or functional plate made of plastic, forming three areas of bus, 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 are drawer type switchgear. What are the usage conditions for MNS low-voltage drawer cabinets?

MNS低壓抽屜式開關(guān)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(jī)場、碼頭以及廣播電視等通信點(diǎn)，來作為發(fā)電、輸配電、電能轉(zhuǎn)換及電能消耗設(shè)備的控制，并通過電容補(bǔ)償柜對其主母線進(jìn)行無功補(bǔ)償。符合國標(biāo)準(zhǔn)：GB7251.1《低壓成套開關(guān)設(shè)備》IEC60439《低壓成套開關(guān)設(shè)備和控制設(shè)備》。

MNS low-voltage drawer type switchgear is suitable for three-phase and five-wire power supply systems with AC 50 (60) Hz, rated working voltages of 400V, 660V, and rated currents of 5000A and below. It can be used at communication points such as power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, and radio and television stations to control power generation, transmission and distribution, power conversion, and power consumption equipment, and provide reactive compensation for its main bus through capacitance compensation cabinets. Comply with national standards: GB7251.1 "Low Voltage Switchgear" IEC60439 "Low Voltage Switchgear and Control Equipment".

正常使用條件：

Normal use conditions:

1、周圍空氣溫度不高于+40℃,不低于-5℃,并且24h內(nèi)其平均溫度不高于+35℃。

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

2、周圍空氣相對濕度在溫度為+40℃時(shí)不超過50%，在較低溫度時(shí)有較高的相對濕度，如+20℃時(shí)為90%,但考慮到由于溫度的變化有可能會偶然產(chǎn)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, due to temperature changes, moderate condensation may occasionally occur.

3、戶內(nèi)使用，使用地點(diǎn)的海抜高度不得超過2000m。

3. For indoor use, the sea level of the place of use shall not exceed 2000m.

4、應(yīng)安裝在無劇烈震動和沖擊，以及不使用電器元件受到腐蝕的場所。

4. It should be installed in a place free from severe vibration and impact, and where electrical components are not subject to corrosion.
