AC HV Disconnect Switch
1. Rated Voltage: 12kV
2. Three-Phase AC 50/60Hz
AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) Disconnector Switch is an advanced indoor electric apparatus designed for a rated voltage of 12kV, and operates with three-phase AC 50/60Hz.
2. It is expertly crafted to efficiently make, break, and transfer current for high-voltage electric apparatus during conditions with voltage but no load, ensuring seamless operation.
3. This switch is ingeniously equipped with a rotary moving contact, facilitating easy mounting on the switchgear for optimal performance.
4. It also boasts a robust wall-through installation feature, enhancing its versatility and reliability.
In the realm of electrical engineering, a disconnector, also known as a disconnect switch or isolator switch, plays a vital role in ensuring that an electrical circuit is completely de-energized for service or maintenance. These switches are crucial for breaking circuits and are commonly seen in electrical distribution and substations, where machinery must have its power source removed for adjustments or repairs. Disconnectors can be operated manually or by motor and are often paired with an earthing switch to ground isolated sections, ensuring the utmost safety for equipment and personnel. High-voltage isolation switches are indispensable in electrical substations, allowing for the isolation of essential apparatus like circuit breakers, transformers, and transmission lines, facilitating maintenance procedures. While disconnectors are primarily designed for safety isolation rather than routine circuit control, they differ from load switches and circuit breakers by lacking arc suppression mechanisms necessary for interrupting high-current conductors. Thus, they are off-load devices, possessing minimal breaking capacity, intended to be opened only after current interruption by another control device.
