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 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".
Normal use conditions:
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. 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. For indoor use, the sea level of the place of use shall not exceed 2000m.
4. It should be installed in a place free from severe vibration and impact, and where electrical components are not subject to corrosion.
