Detailed information
summary
The MNS low-voltage withdrawable switchgear complete set equipment is an advanced low-voltage switchgear developed by our company to meet the needs of customer industrial development. It refers to the design of low-voltage switchgear at home and abroad and has been improved and developed. This product complies with the national standard GB7251.1-1997, industry standard JB/T9661-1999, and international standard IEC439-1.
The MNS type low-voltage withdrawable switchgear equipment is suitable for various power supply and distribution needs, and can be widely used in various low-voltage distribution systems such as power plants, substations, industrial and mining enterprises, buildings and hotels, municipal construction, etc.
characteristic
The complete set of MNS low-voltage withdrawable switchgear equipment has the following obvious characteristics:
Compact design: accommodates more functional units in a smaller space. The structural components have strong universality and flexible assembly, with E=25mm as the modulus. The structure and pull-out units can be combined arbitrarily to meet the needs of system design.
The busbar is protected by high-strength flame-retardant and high insulation strength plastic functional boards, which have anti fault arc performance and ensure safe and reliable operation and maintenance.
The mechanical interlocking mechanism of various sizes of drawers complies with standard regulations, with three obvious positions for connection, testing, and separation, ensuring safety and reliability.
The use of high-strength flame-retardant engineering plastics effectively enhances the protective and safety performance.
The cabinet can be selected with corresponding protection levels according to different requirements of the working environment.
The equipment has high continuity and reliability in operation.
Normal usage conditions
The ambient air temperature shall not exceed+40 ℃, and the average temperature within 24 hours shall not exceed+35 ℃. The lower limit of ambient air temperature is -5 ℃.
The air is clean, with a relative humidity not exceeding 50% at a maximum temperature of+40 ℃. At lower temperatures, a higher relative humidity is allowed. For example, the relative humidity is 90% at+20 ℃. However, it should be taken into account that moderate condensation may occur accidentally due to temperature changes
The altitude of the installation site shall not exceed 2000 meters.
In places without explosive gases, chemical corrosive gases, dust that can damage insulation, and severe vibrations, the installation inclination should not exceed 5 degrees.
This device is suitable for transportation and storage within the following temperature range: -25 ℃ to+55 ℃, and can reach+70 ℃ in a short period of time (not exceeding 24 hours).
When the above environmental conditions are exceeded, please consult with the manufacturer.
