Product Advantages
- 1.MNS type low-voltage switchgear frame is a combined structure, and the basic skeleton is assembled by C-type steel. All the structural components of the cabinet frame are galvanized and securely onnected to the basic cabinet frame by self-tapping locking screws or 8.8-level hexagon bolts. The cabinet is assembled into a complete switch cabinet with doors, partitions, mounting brackets, and bus function units corresponding to the change of the solution. The internal size of the switch cabinet, the size of the parts and the size of the compartment are changed according to the modularization (E=25mm).
2. Each cabinet of MNS type combined low-voltage switchgear is divided into three rooms, namely, the horizontal bus room (in the back of the cabinet), the drawer room (in the front of the cabinet), and the cable room (in the lower part of the cabinet or the right side of the cabinet). The room is separated from the room by steel plate or high-strength flame-retardant plastic function board, and the metal plate with ventilation hole is isolated between the upper and lower drawers to effectively prevent the flarc caused by the fault of the switch element or the accident caused by the short circuit of the bus and other lines.
3. The structural design of MNS type low-voltage switchgear can meet the requirements of various inlet and outlet lines: upper inlet and lower outlet, upper inlet and lower outlet, and lower inlet and lower outlet.
4. Compact design: Accommodate more functional units in a smaller space
5. The structural parts have strong versatility and flexible assembly, with E=25mm as the module, and the structure and extraction unit can be arbitrarily combined to meet the needs of the system design
6. The bus bar is protected by the high-strength flame-retardant and high-insulation plastic functional board, which has the performance of anti-fault arc, making the operation and maintenance safe and reliable
7. The mechanical interlocking mechanism of various sizes of drawers meets the standard provisions, and there are three obvious positions of connection, test and separation, which are safe and reliable.
8. Standard module design: can be composed of protection, operation, conversion, control, adjustment, measurement, indication and other standard units, can be arbitrarily assembled according to requirements.
9. The use of high-strength flame-retardant engineering plastics, effectively strengthen the protection and safety performance.
10. High degree of universality, standardization, convenient assembly. With reliable quality assurance.
11. The cabinet can be selected according to the different requirements of the working environment.
12. Continuity and reliability of equipment protection
Application Places
MNS low-voltage cabinet is widely used in distribution power stations, factories, industrial and mining enterprises, nuclear power stations and building distribution.
MNS low voltage cabinet is a low voltage withdrawable switchgear, its design and use scenario mainly consider a variety of environmental factors and technical requirements. First of all, the design of MNS low pressure cabinet takes into account the range of ambient air temperature, stipulates that the ambient air temperature does not exceed +40℃, and not lower than -5℃, to ensure that it can work normally under various environmental conditions. in addition, takes into account the cleanliness of the air and the relative humidity, stipulates that the relative humidity of should not exceed 50% when the highest temperature is +40℃, while a higher relative humidity is allowed at lower temperature, for example 90% at +20℃, ADAPTS to a variety of environmental conditions. altitude has also been limited to less than 2,000 meters, to ensure equipment can work properly in the plateau region.
