MNS low-voltage drawer-type switchgear (hereinafter referred to as "the equipment") is comprehensively optimized based on the MNS series low-voltage switchgear of ABB Switzerland, adopting a standard modular design. This equipment is suitable for AC 50Hz systems with rated working voltage of 660V and below, and can be used as a control device for various power generation, transmission, distribution, energy conversion and electrical equipment. It is widely used in low-voltage distribution systems of various mining enterprises, high-rise buildings and hotels, municipal construction, etc. In addition to conventional land use, after special treatment, it can also be used for offshore oil drilling platforms and nuclear power plants. This equipment complies with the international standard IEC 439-1 and the national standard GB 7251.1.
1. Compact structure: Occupies less space and integrates more functional units.
2. Strong structural versatility and flexible assembly. The C-type profile with a module of 25 mm can meet the needs of various structural forms, protection levels and usage environments.
3. Adopts standard modular design, which can be combined to form standard units for protection, operation, transfer, control, regulation, metering, indication, etc. Users can freely select and assemble as needed. The cabinet structure and drawer units can be assembled from more than 200 components.
4. Excellent safety: A large number of high-strength flame-retardant engineering plastic components are used to effectively improve protection and safety performance.
5. Excellent technical performance: Main parameters reach the advanced domestic level.
1. Ambient air temperature: -5℃～+40℃, the average temperature within 24 hours shall not exceed +35℃.
2. Air conditions: Clean air; relative humidity shall not exceed 50% at +40℃; higher relative humidity is allowed at lower temperatures, for example, up to 90% at +20℃; however, slight condensation may occur considering temperature changes.
3. Altitude: Not exceeding 2000 meters.
4. This equipment is suitable for transportation and storage, with a temperature range of -25℃～+55℃; it can withstand +70℃ for a short time (within 24 hours); under extreme temperature conditions, the equipment should not suffer irreversible damage and should be able to operate normally under normal conditions.
5. If the above operating conditions cannot meet the user's needs, please contact the manufacturer for consultation.
6. If this equipment is used for offshore oil drilling platforms or nuclear power plants, a separate technical agreement must be signed.
Structural Features
The basic cabinet of this equipment adopts a combined assembly structure. The basic structural components of the cabinet are galvanized parts, which are connected and fixed into a basic frame through self-tapping locking screws or grade 8.8 square neck screws. According to project change requirements, corresponding doors, cover plates, partitions, mounting supports, busbars, functional units and other components can be additionally configured to assemble a complete set of equipment. The internal components and compartment dimensions implement modular design (module unit e=25 mm).
