AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an advanced indoor electrical apparatus with a rated voltage of 12kV, designed for three-phase AC50/60Hz applications.
2. Engineered to manage break and transfer current, this high-voltage electric apparatus excels in situations with voltage presence but no load, ensuring seamless operational transitions.
3. It features a rotary moving contact system, conveniently mounted on the switchgear for effortless implementation and effective performance.
4. Additionally, it supports wall-through installation, providing versatility and adaptability in various setups.
In the realm of electrical engineering, the disconnector, also known as a disconnect switch or isolator switch, plays a pivotal role in ensuring complete de-energization of an electrical circuit for both service and maintenance purposes. These devices are primarily used for circuit interruption, often located in electrical distribution systems and substations where machinery necessitates the removal of power sources for adjustments or repairs. Disconnectors can function manually or be motor-operated and may be paired with an earthing switch, securing the isolated section from the system to protect both the equipment and personnel. High-voltage isolation switches, crucial in substations, facilitate the disconnection of apparatus like circuit breakers, transformers, and transmission lines for maintenance. Typically not intended for routine circuit control, disconnectors are dedicated to safety isolation. Unlike load switches and circuit breakers, disconnectors lack arc suppression mechanisms, handling only off-load operations with minimal breaking capacity, intended to be opened post current interruption by another control device.
