AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is a state-of-the-art indoor electric apparatus designed for applications with a rated voltage of 12kV, catering to three-phase AC 50/60Hz systems.
2. It serves the crucial function of making, breaking, and transferring current for high-voltage electric apparatus under conditions of voltage presence without load, ensuring seamless power management.
3. This innovative switch employs a rotary moving contact, meticulously mounted on the switchgear for user-friendly operation and enhanced reliability, ensuring ease of maintenance.
4. It is engineered to adopt a wall-through installation, providing robust performance and flexibility in diverse installation environments.
In the realm of electrical engineering, the disconnector, also known as a disconnect or isolator switch, plays an essential role in ensuring complete de-energization of electrical circuits, facilitating safe service or maintenance. These switches are instrumental in circuit breaking and are commonly deployed in electrical distribution and substations, where machinery must be safely disconnected from power sources for adjustments or repairs. Disconnectors may be manually or motor operated, and often incorporate an earthing switch to ground isolated components, safeguarding both equipment and personnel. High-voltage isolation switches are pivotal in substations, enabling the isolation of critical apparatus like circuit breakers, transformers, and transmission lines for maintenance purposes. Primarily designed for safety isolation rather than regular circuit control, disconnectors differ from load switches and circuit breakers by lacking arc suppression mechanisms, as they are off-load devices with minimal breaking capacity, intended for operation only after current interruption by other control devices.
