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 a groundbreaking indoor electrical apparatus with a rated voltage of 12kV. It's designed for three-phase AC systems operating at 50/60Hz.
2. Expertly crafted to manage, break, and transfer current for high-voltage electric devices, this switch operates seamlessly in no-load settings.
3. Its cutting-edge design features an innovative rotary moving contact, easily mounted on the switchgear for superior functionality.
4. Engineered for versatility, it also supports wall-through installation to meet diverse operational requirements.
In the realm of electrical engineering, the disconnector, or disconnect switch, serves as a critical tool for de-energizing an electrical circuit, ensuring safe service or maintenance. Employed for circuit disengagement, these switches are essential in electrical distribution and substations, enabling secure machinery adjustments or repairs. Available in manual or motor-operated versions, disconnectors may be partnered with an earthing switch, grounding the isolated section to protect equipment and personnel. Specifically in high-voltage applications, these isolation switches play a pivotal role in substations, facilitating the maintenance of crucial components like circuit breakers, transformers, and transmission lines. While primarily intended for safety isolation rather than regular circuit control, disconnectors, unlike load switches and circuit breakers, do not possess mechanisms for suppressing electric arcs. Consequently, they are classified as off-load devices, characterized by a minimal breaking capacity, and are intended for operation only after current interruption by another control apparatus.
