AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an indoor apparatus with a rated voltage of 12kV, suitable for three-phase AC 50/60Hz systems. Ideal for indoor installations, it offers unparalleled reliability.
2. It's expertly crafted to manage, break, and transfer current for high-voltage electric apparatuses in no-load scenarios, ensuring seamless operations.
3. The switch features a rotary moving contact, engineered for easy mounting on switchgear, simplifying maintenance and operation.
4. Designed with a wall-through installation option, it enhances installation flexibility.
In the realm of electrical engineering, a disconnector, often referred to as a disconnect switch or isolator switch, plays an integral role in de-energizing an electrical circuit for maintenance or service. These devices are pivotal in breaking circuits safely, crucial in environments like electrical distribution systems and substations where machinery requires power removal for repairs. Disconnectors can be manually or motor-operated and are often coupled with an earthing switch to safely ground isolated sections, ensuring both equipment and personnel safety. In high-voltage applications, isolation switches facilitate the maintenance of circuit breakers, transformers, and transmission lines within substations. Though not designed for routine circuit control, disconnectors provide indispensable safety isolation. Unlike load switches and circuit breakers, they lack arc suppression mechanisms, meaning they should only be opened after circuit interrupters have ceased current flows, emphasizing their function as off-load devices with minimal breaking capacity.
