AC HV Disconnect Switch
1. Rated Voltage: 12kV
2. Three-Phase AC 50/60Hz
AC HV Disconnect Switch
• Summary:
1. GN30-12(D) disconnect switch, an advanced indoor electric apparatus, boasts a rated voltage of 12kV, designed for three-phase AC 50/60Hz operations.
2. It efficiently handles the making, breaking, and transfer of current for high voltage electrical apparatus, optimizing operations where voltage is present but with no load.
3. The switch is equipped with a rotary moving contact, seamlessly mounted on the switchgear for ease of use and enhanced operational efficiency.
4. It features wall-through installation, providing a streamlined and secure setup.
In the realm of electrical engineering, a disconnector, also known as a disconnect switch or isolator switch, is pivotal for guaranteeing that an electrical circuit is completely de-energized for service or maintenance. These switches are crucial for circuit interruption and are commonly seen in electrical distribution and substations, where the removal of driving power from machinery is essential for adjustments or repairs. Disconnectors might be manually or motor operated and are often paired with earthing switches to ensure that isolated portions are safely grounded, safeguarding both equipment and personnel. High-voltage isolation switches are indispensable in electrical substations, facilitating the maintenance-driven isolation of equipment such as circuit breakers, transformers, and transmission lines. While these disconnectors are not typically used for regular circuit control, they serve as vital safety isolation tools. Unlike load switches and circuit breakers, disconnectors are devoid of electric arc suppression mechanisms, which makes them off-load devices with minimal breaking capacity, designed to be opened only after other control devices have interrupted the current.
