AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an innovative indoor electric apparatus with a rated voltage of 12kV, designed for three-phase AC50/60Hz applications.
2. This switch is expertly crafted to enable the making, breaking, and transfer of current for high-voltage electric apparatus in environments with voltage and no-load, ensuring seamless operation.
3. The switch boasts a rotary moving contact system mounted on the switchgear, ensuring effortless installation and reliable performance.
4. Additionally, it embraces wall-through installation, enhancing its versatility and ease of use.
In the realm of electrical engineering, a disconnector, disconnect switch, or isolator switch is an essential device that guarantees complete de-energization of an electrical circuit for service or maintenance. These devices serve the critical function of circuit breaking and are prominently featured in electrical distribution and substations, where machinery must be safely powered down for adjustments or repairs. Disconnectors can be either manually or motor-operated and can be paired with an earthing switch to ground isolated portions, ensuring the utmost safety for both equipment and personnel. High-voltage isolation switches are indispensable in electrical substations, providing isolation for essential apparatus such as circuit breakers, transformers, and transmission lines during maintenance. It's important to note that disconnectors are primarily intended for safety isolation and are not designed for normal circuit control. Unlike load switches and circuit breakers, disconnectors lack electric arc suppression mechanisms necessary for handling high-current interruptions. As such, they are classified as off-load devices with minimal breaking capacity, intended to be opened only after current has been safely interrupted by another control device.
