2. Three-Phase AC 50/60Hz
AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) Disconnect Switch stands as a premier indoor electric device characterized by a rated voltage of 12kV and designed for three-phase AC at 50/60Hz.
2. Engineered to expertly manage, break, and transfer current, this device functions optimally in high-voltage environments where voltages prevail without loads.
3. Its innovative design features a rotary moving contact that is seamlessly mounted within the switchgear for effortless operation.
4. It additionally incorporates a wall-through installation capability, enhancing its adaptability and reliability.
In the realm of electrical engineering, a disconnect switch, also known as a disconnector or isolator switch, serves the critical function of ensuring an electrical circuit is completely de-energized for service or maintenance. These switches are specifically designed for circuit interruption and are prevalently utilized within electrical distribution systems and substations, where the cessation of machinery's driving power is essential for adjustment or repair purposes. Disconnectors can be operated manually or through motorization and are frequently accompanied by an earthing switch to ground the isolated section, thereby safeguarding both equipment and personnel. High-voltage isolation switches play a vital role in substations, permitting the isolation of apparatus such as circuit breakers, transformers, and transmission lines for maintenance purposes. Unlike load switches and circuit breakers, disconnectors do not incorporate mechanisms for electric arc suppression, which is crucial when high-current conductors are interrupted. Consequently, they are classified as off-load devices with minimal breaking capacity, and their operation is intended solely after the current has been safely interrupted by alternate control devices.
