MNS low-voltage drawer cabinet is a product manufactured according to the transferred technology, and is applicable to the power system with AC 50 (60) Hz and rated working voltage of 660V and below. It is used for the control of power generation, transmission, distribution, power conversion and power consumption equipment. The performance and application environment of MNS low-voltage drawer cabinet are described below.
The basic cabinet frame of the power distribution cabinet is a combined assembly structure. All structural parts of the cabinet frame are galvanized, fastened with self-tightening screws and Grade 8.8 hexagon screws, and connected to form a basic frame. Then, according to the change of the scheme, the corresponding doors, sealing plates, partitions, mounting brackets, buses, functional units and other components are added to form a complete set of equipment.
The size of parts and components in the distribution cabinet and the size of the compartment shall be modular (modular unit E=25mm). The withdrawable functional unit has five standard sizes: 8E/4, 8E/2, 8E, 16E and 24E. The total height of the functional unit compartment is 72E.
The withdrawable functional unit and the cabinet body are equipped with mechanical interlocking device to meet the operation requirements. They can only be moved when the main circuit and auxiliary circuit are all disconnected. The mechanical interlocking device enables the drawer to have the test position, breaking position, connection position and separation position. Scope of application
MNS low-voltage draw-out switch cabinet is applicable to power plants, substations, petrochemical, metallurgy, steel rolling, light industry and textile and other factories and mining enterprises, residential areas, high-rise buildings and other places, and is used for power conversion, distribution and control of power distribution equipment of power systems with AC 50-60Hz, rated working voltage AC 660V and below.
The ambient air temperature is not higher than+40 ℃, not lower than - 5 ℃, and the average temperature within 4 hours is not higher than+35 ℃. Atmospheric conditions: the air is clean, and the relative temperature is not more than 50% at the high temperature of+40 ℃ in Z, and the relative humidity is allowed to be higher at the low temperature, for example, 90% at+20 ℃. However, due to the test change, it should be considered that there may be occasional moderate condensation.
□ The device is suitable for the transportation and storage process of the following temperatures: within the range of - 25 ℃ to 55 ℃, it can reach+70 ℃ in a short time (no more than 24h). Under these extreme temperatures, the device should not be damaged irreparably, and it should be able to work normally under normal conditions.
