Air Insulated Metal Enclosed Modular Switchgear
Air Insulated Metal Enclosed Modular Switchgears can be produced with different brand components if required.
Air Insulated Metal Enclosed Modular Switchgears
Air Insulated Metal Enclosed Modular Switchgears consist of 4 main parts. The safety of these sections is ensured by switching and mechanical locking, and they are isolated from other sections with transitions that provide continuity.
AIR INSULATED MODULE CELL SECTIONS
A- Main Busbar Section
In the Main Busbar Section, there are electrolytic coppers, insulators and bushings selected in accordance with the rated current. Access to this section requires special instructions and safety precautions.
B- Cable Connection Section
Cable Connection Section varies depending on the product type. Available products are as follows:
- SF6 Gas Circuit Breaker
- SF6 Gas Load Separator
- SF6 Gas Separator
- Voltage Transformer
- Current Transformer
- High Voltage Fuse
- Capacitive Voltage Divider
- Cable Connection System Equipment
C- Switching (Operating Mechanism) Section
It is the section that allows close maneuvering of switching equipment for opening and closing.
D- Low Voltage Section
This section contains all secondary circuits for control.
(Dimensions, Protection, Monitoring, Communication and other related systems.)
Maintenance and Control
Armtek “ARME Series” offers more safety and maximum ease of maintenance. The production facilities are ISO-9001 certified, and quality is assured with extensive design and production tests. The low voltage compartment provides sufficient space to easily test and replace internal cables. The independent busbar compartment is structured so that it does not affect any accidents in adjacent panels. Therefore, it does not pose a risk when performing maintenance and control in other sections. Maintenance and control times are minimized due to the easy disassembly and assembly of all equipment.
Security Considerations
Air Insulated Modular Switchgears are designed to prevent explosion or damage to peripheral devices in the event of internal arcing. A high degree of safety for the user and the environment is provided in Air Insulated Modular Switchgears. Short circuit, short-term current and internal arc tests have been tested in accredited certified laboratories in accordance with the IEC 62271-200 standard. It is in IP3X protection class to protect from the external environment.
Security measures are provided against incorrect use and applications thanks to mechanical locking and various precautions. It is not possible to open the cell door without closing the grounding switch and turning the cut-off and disconnectors to the open position. All maneuvers and operations are disabled while the cell door is open.
It is connected with mechanical interlocks between the sections of the cells and with other cells it is related to. The hinge and lock system has a solid structure and is a security wall for faulty operations. The IP observation window on the breaker door allows to see the status of the breaker. The grounding key can be locked in accordance with the isolation and line security. The security of the line as a whole is ensured with communication and signal systems.
