MNS low voltage withdrawable switchgear
MNS low voltage draw out switchgear is applicable to the power system with AC 50Hz-60Hz and rated working voltage of 660V and below. It is used as the control of power generation, transmission, distribution, electric energy conversion and electric energy consumption equipment. In addition to general land use, the switchgear can also be used in offshore oil well platform nuclear power plants after treatment.
Service conditions
1. The ambient air temperature is not higher than +40 ℃, not lower than - 5 ℃, and the average temperature within 24 hours is not higher than +35 ℃.
2. The air shall be clean, and the relative humidity shall not exceed 50% when the temperature is +40 ℃. A higher relative humidity is allowed at a lower temperature. For example, 90% at +20 ℃. However, temperature changes should be considered: condensation may occur accidentally.
3. The altitude shall not exceed 2000mm.
4. This device is applicable to the transportation and storage of the following temperatures: between 30 ℃ and +55 ℃, it can reach +70'℃ in a short time (no more than 24 hours). Under these temperatures, the device should not suffer any unrecoverable damage, and it should work normally under normal conditions.
characteristic
1. Compact design: it can accommodate more functional units in a small space.
2. The structure has strong versatility and flexible assembly. The C-shaped profile with a modulus of 25mm can meet the requirements of various structural types, protection levels and use environments.
3. Adopt standard module design: it can form standard units such as protection, operation, conversion, control, regulation, measurement, indication, etc. Users can choose and assemble according to their needs, and more than 200 kinds of parts can form different cabinet frame structures and drawer units.
4. Good protection: a large number of high-strength flame-retardant engineering plastic components are used to enhance the protection performance.
5. High technical performance: the main parameters have reached the domestic advanced level.
6. Reliability: it has ideal thermal cycle heat dissipation effect, so that the quality of power supply and distribution can be guaranteed
