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 stands as a premium indoor electric apparatus designed for a rated voltage of 12kV, adeptly handling three-phase AC at both 50 and 60Hz.
2. This robust switch is engineered to skillfully make, break, and transfer currents for high-voltage electrical apparatuses in environments characterized by voltage presence but no load.
3. Featuring a rotary moving contact, this innovative switch is seamlessly mounted on the switchgear, ensuring effortless integration and operation.
4. Additionally, it is equipped with a wall-through installation feature, enhancing its versatility and ease of use.
In the realm of electrical engineering, disconnectors, also known as disconnect switches or isolator switches, play a crucial role in guaranteeing that an electrical circuit is thoroughly de-energized for service or maintenance purposes. Their prime function is to break the circuit, widely utilized in electrical distribution and substations, where the power source must be removed for equipment adjustments or repairs. These switches can be operated manually or motor-driven and may be coupled with an earthing switch to ground isolated sections, ensuring the utmost safety for both equipment and personnel. High-voltage isolation switches are indispensable in substations, enabling the safe maintenance of apparatuses such as circuit breakers, transformers, and transmission lines. While not designed for routine circuit control, disconnectors provide essential safety by isolating circuits. Unlike load switches or circuit breakers, they do not possess arc suppression mechanisms, thus serving as off-load devices with minimal breaking capacity, intended for operation only after currents are interrupted by other devices.
