AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is an indoor marvel with a rated voltage of 12kV, ready to handle three-phase AC50/60Hz operations seamlessly.
2. It excels in breaking and transferring current for high voltage electric apparatus, especially in no-load conditions.
3. The switch's rotary moving contact, effortlessly mounted on switchgear, speaks to its easy integration and technological advancement.
4. Wall-through installation is another hallmark of its clever design, ensuring practicality and efficiency.
In electrical engineering, a disconnector, also known as a disconnect switch or isolator switch, plays a crucial role in ensuring an electrical circuit is completely de-energized for service or maintenance. Used primarily for breaking the circuit, these devices are indispensable in electrical distribution and substations, where machinery must have its power source removed for adjustments or repairs. Disconnectors can be operated manually or by a motor and may come with an earthing switch to ground the isolated portion, ensuring the utmost safety for both equipment and personnel. High-voltage isolation switches in substations facilitate the isolation of apparatus such as circuit breakers, transformers, and transmission lines during maintenance. Typically, a disconnector is not used for normal circuit control; instead, it ensures safety isolation. Unlike load switches and circuit breakers, disconnectors do not have arc suppression mechanisms and are thus off-load devices with very low breaking capacity, designed to be opened only after current interruption by another control device.
