Overview
The MNS low-voltage draw-out type switchgear (hereinafter referred to as switchgear) developed by RUY Power with reference to the MNS series low-voltage switchgear of ABB company and comprehensively improved is currently a relatively complete low-voltage draw-out type complete set of equipment in China. The product is composed of standardized, serialized modules, and the cabinet has reliable mechanical interlocking devices, making users safer and more reliable in use.
This switchgear is suitable for AC 50(60)Hz, rated working voltage 400V, 660V, rated current 5000A and below three-phase five-wire power supply system, and can be used in power plants, substations, industrial and mining enterprises, large buildings, airports, docks, and radio and television communication centers, as power receiving, power distribution, electric energy conversion and electric energy consumption equipment, and the capacitor compensation cabinet carries out reactive power compensation for its main line. It complies with standards: GB7251.1 “Low-Voltage Complete Switchgear”, IEC60439 “Low-Voltage Complete Switchgear and Control Equipment”.
Operating Conditions
◆ Ambient air temperature not higher than +40℃, not lower than -5℃, and the average temperature within 24h not higher than +35℃.
◆ Ambient air relative humidity at maximum temperature +40℃ not exceeding 50%, and higher relative humidity allowed at lower temperatures, such as +20℃ being 90%, but considering that condensation may occasionally occur due to temperature changes.
◆ For indoor use, the altitude of the installation site shall not exceed 2000m.
◆ It should be installed in places without violent vibration and impact, and without corrosion of electrical components.
