AC HV Disconnect Switch
1. Rated Voltage: 12kV
2. Three-Phase AC 50/60Hz
AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) Disconnect Switch is an advanced indoor electric apparatus designed for a rated voltage of 12kV, effectively managing three-phase AC at 50/60Hz.
2. Expertly crafted to seamlessly make, break, and transfer current for high-voltage electric apparatus under no-load conditions, ensuring reliability and safety.
3. Ingeniously engineered with a rotary moving contact, this switch is effortlessly mounted on the switchgear.
4. Designed with a wall-through installation, ensuring compatibility and ease of use in various setups.
In the realm of electrical engineering, the disconnector, also known as a disconnect or isolator switch, serves a vital role by ensuring an electrical circuit is thoroughly de-energized for maintenance or service. These disconnectors are exclusively employed to break the circuit and are indispensable in electrical distribution and substations, where machinery demands its power source to be cut off for adjustments or repairs. Disconnectors can be operated manually or via motors and often come equipped with an earthing switch to ground isolated portions, ensuring utmost safety for equipment and personnel. High-voltage isolation switches are pivotal in electrical substations, enabling the isolation of equipment like circuit breakers, transformers, and transmission lines for maintenance purposes. Not typically designed for regular circuit control, disconnectors serve primarily for safety isolation. Distinct from load switches and circuit breakers, they lack arc suppression mechanisms, essential for safely interrupting high-current electrical conductors. Consequently, they are off-load devices with minimal breaking capacity, intended only to be opened once current has been interrupted by another control device.
