AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an exceptional indoor apparatus, boasting a rated voltage of 12kV for three-phase AC50/60Hz systems. It exemplifies efficiency and reliability.
2. This switch facilitates the breaking and transferring of currents in high-voltage electric apparatuses, particularly in no-load scenarios, ensuring safe and controlled operations.
3. With a design that incorporates a rotary moving contact, it is conveniently mounted on switchgear, providing ease of use and maintenance.
4. The installation accommodates wall-through setups, offering flexibility and adaptability in various electrical configurations.
In the realm of electrical engineering, disconnectors, also known as disconnect switches or isolator switches, are crucial for ensuring circuits are completely de-energized for service or maintenance. These essential devices are solely for circuit breaking, often found in electrical distribution and substations, where machinery requires power removal for adjustments or repairs. Disconnectors can be manually or motor operated and are frequently paired with earthing switches to ground isolated sections, safeguarding both equipment and personnel. High-voltage isolation switches are invaluable in substations, providing isolation for apparatus like circuit breakers, transformers, and transmission lines during maintenance. While not intended for routine circuit control, disconnectors ensure safety isolation, lacking arc suppression mechanisms typical of load switches and circuit breakers. Therefore, they are off-load devices, meant to be opened only after current interruption by alternate control devices.
