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 sophisticated indoor electric apparatus boasting a rated voltage of 12kV, perfectly designed for three-phase AC systems operating at 50/60Hz.
2. This switch is engineered to safely make, break, and transfer current for high-voltage electric apparatus in scenarios with voltage presence yet devoid of load.
3. It features a rotary moving contact system, conveniently mounted on the switchgear, ensuring seamless operational ease.
4. The design incorporates wall-through installation, enhancing its adaptability and ease of use.
In the realm of electrical engineering, a disconnector, often termed a disconnect switch or isolator switch, plays a pivotal role in ensuring complete de-energization of an electrical circuit to facilitate service or maintenance. These devices are indispensable for circuit interruption and are predominantly utilized in electrical distribution and substations. Here, machinery requires a complete removal of its power source for adjustments or repairs. Available in both manual and motor-operated forms, disconnectors can be enhanced with an earthing switch to securely ground isolated sections, safeguarding equipment and personnel. High-voltage isolation switches are a staple in electrical substations, aiding in the isolation of apparatus like circuit breakers, transformers, and transmission lines for maintenance. Primarily designed for safety isolation, disconnectors lack the arc suppression mechanisms seen in load switches and circuit breakers. Hence, they are classified as off-load devices with minimal breaking capacity, intended to be opened post-current interruption by another control device.
