Product Overview
RMR-40.5 series indoor AC high-voltage vacuum load switch and load switch-fuse combination unit (hereinafter referred to as the series solid-sealed vacuum load switch) are independently designed and developed by our company in accordance with GB3804、GB16926 and IEC 62271.They are suitable for AC 50 Hz, rated voltage 40.5 kV systems, specially designed for 35 kV wind power and solar power systems.They can be used as independent electrical units in 40.5 kV power systems or box-type substations.The product features a reasonable structure and adopts the CTE3 two-stage transmission spring operating mechanism, which is independently developed by our company and has won the national invention patent, ensuring simple and reliable operation.
Model Explanation
Indoor AC High-Voltage Vacuum Load Switch
Indoor AC High-Voltage Vacuum Load Switch-Fuse Combination Unit
Operating Environment Conditions
- Ambient temperature: -25℃ to +40℃;
- Relative humidity: daily average ≤ 95%, monthly average ≤ 90%;
- The ambient air is free from significant contamination by dust, smoke, corrosive or flammable gases, vapors, or salt spray;
- No fire or explosion hazards at the installation site;
- Seismic intensity ≤ 8 degrees; installation site with an inclination ≤ 5°.
Note: The above are the conventional operating conditions specified in GB/T 11022. For special environments such as high altitude, heavy salt spray, or extreme cold/heat, the technical design can be modified for custom manufacturing based on the above requirements.
