Key Features

Enhanced Safety Mechanisms
The Armored Removable AC Metal-Enclosed Switchgear is equipped with a comprehensive set of interlocking mechanisms to prevent operational errors. These safety features include:
- Prevention of moving the circuit breaker trolley under load conditions.
- Blocking of the circuit breaker operation when the grounding switch is in the closed position.
- Prevention of closing the grounding switch when the circuit breaker is energized.
- Restriction of access to live competitions to avoid accidental contact with energized components.
These robust safety measures significantly reduce the risk of human error and enhance the overall security of electric systems.

High-Quality Vacuum Circuit Breakers
This switchgear incorporates VS1 and VN2 series medium-voltage vacuum circuit breakers, renowed for their good performance performance in breaking and making current with relatively small arc energy. These vacuum circuit breakers ensure high insulation strength, long service life, and reliable short-circuit protection. The inclusion of sealed vacuum interrupters enhances the durability and operational efficiency of the Armored Removable AC Metal-Enclosed Switchgear.

Advanced Control and Protection
To ensure optimal system protection and monitoring, the switchgear’s secondary circuit is equipped with highly reliable control and protection components. These elements include microprocessor-based relays and digital monitoring systems that facilitate real-time status tracking and fault diagnosis. This intelligent design helps to optimize maintenance schedules and improve overall network reliability.

good Insulation and Structural Integrity
The Armored Removable AC Metal-Enclosed Switchgear employs advanced insulation technologies, including heat-shrink insulation materials and epoxy-coated busbars. The optimized electrode design and compact cabinet structure minimize electric stress and improve insulation performance. These features contribute to enhanced safety, long-term reliability, and efficient space utilization.

Operating and Environmental Conditions
Designed to operate under a wide range of environmental conditions, the switchgear meets stringent industry standards:
- the largest ambient temperature: 40°C
- rudimentary ambient temperature: -15°C
- 24-hour average temperature not exceeding 35°C
- the largest daily relative humidity: 95%
- the largest monthly relative humidity: 90%
- the largest daily vacuum pressure: 2.2 kPa
- the largest monthly vapor pressure: 1.8 kPa
- Altitude not exceeding 1000m
- Protection from dust, smoke, corrosive gases, steam, and salt mist contamination
- Negligible external vibrations or seismic activity
- Electronic magnetic interference (EMI) within acceptable limits, ensuring secondary system voltage induction remains below 1.6kV

Customizable Heating and Condensation Prevention
To mitigate condensation risks, the Armored Removable AC Metal-Enclosed Switchgear is equipped with built-in heaters. These heating elements are activated when the switchgear is in standby mode and can also operate during normal system functions to maintain optimal humidity levels within the enclosure.

Special Operating Conditions
For environments where standard operating conditions are exceeded, the switchgear can be customized through mutual agreements between the manufacturer and the user. Specialized adaptations, such as additional insulation enhancements and reinforced environmental sealing, can be implemented to meet specific application needs.

The Armored Removable AC Metal-Enclosed Switchgear is a technically advanced and highly reliable distribution solution for medium-voltage power systems. With its robust safety interlocks, high-performance vacuum circuit breakers, advanced control features, and good insulation, this switchgear ensures stable and secure electrical network operation.
