MNS低压抽屉式开关柜是采用钢板制成封闭外壳，进出线回路的电器元件都安装在可抽出的抽屉中，构成能完成某一类供电任务的功能单元。功能单元与母线或电缆之间，用接地的金属板或塑料制成的功能板隔开，形成母线、功能单元和电缆三个区域。每个功能单元之间也有隔离措施。抽屉式开关柜有较高的可靠性、防护性和互换性，是比较好的开关柜，目前生产的开关柜，多数是抽屉式开关柜。那么MNS低压抽屉柜使用条件有哪些呢？

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低压抽屉式开关柜适用于交流50(60)Hz、额定工作电压400V、660V,额定电流5000A及以下三相五线制的电力供电系统，可用于发电厂、变电所、工矿企业、大楼宾馆、机场、码头以及广播电视等通信点，来作为发电、输配电、电能转换及电能消耗设备的控制，并通过电容补偿柜对其主母线进行无功补偿。符合国标准：GB7251.1《低压成套开关设备》IEC60439《低压成套开关设备和控制设备》。

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".

正常使用条件：

Normal use conditions:

1、周围空气温度不高于+40℃,不低于-5℃,并且24h内其平均温度不高于+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、周围空气相对湿度在温度为+40℃时不超过50%，在较低温度时有较高的相对湿度，如+20℃时为90%,但考虑到由于温度的变化有可能会偶然产生适度的凝露。

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、户内使用，使用地点的海抜高度不得超过2000m。

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

4、应安装在无剧烈震动和冲击，以及不使用电器元件受到腐蚀的场所。

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