2. Three-Phase AC 50/60Hz
AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an advanced indoor electrical apparatus designed for a rated voltage of 12kV. This three-phase AC50/60Hz switch offers sophisticated solutions for high-voltage applications.
2. Expertly crafted to manage break and transfer currents, this switch excels in high-voltage electric apparatus scenarios with voltage and no-load conditions, ensuring seamless operation and outstanding reliability.
3. The switch's ingenious rotary moving contact mechanism is strategically positioned on the switchgear for unparalleled ease and efficiency in installation and operation.
4. It also features a robust wall-through installation method, enhancing its adaptability and secure integration into diverse electrical environments.
In the realm of electrical engineering, a disconnector, or disconnect switch, serves as an essential safety device, ensuring complete de-energization of an electrical circuit for maintenance or service. These switches, dedicated to circuit isolation, are indispensable in electrical distribution and substations, where machinery requires power disconnection for adjustments or repairs. Whether manual or motor-operated, disconnectors can be paired with an earthing switch to ground isolated sections, safeguarding both equipment and personnel. High-voltage isolation switches, integral to substations, facilitate the isolation of apparatus like circuit breakers, transformers, and transmission lines for maintenance purposes. Disconnectors are designed exclusively for safety isolation, distinct from load switches and circuit breakers, as they lack arc suppression mechanisms. As off-load devices with minimal breaking capacity, they are intended to be opened only after a current has been interrupted by another control device.
