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 robust indoor device equipped to handle a rated voltage of 12kV for three-phase AC systems at frequencies of 50/60Hz.
2. This essential switch facilitates the making, breaking, and transferring of current in high-voltage electric apparatus, specifically under conditions with voltage and no load.
3. With its advanced rotary moving contact, the switch ensures seamless integration within switchgear, enhancing operational ease and reliability.
4. The switch also incorporates a wall-through installation, providing versatility and streamlined functionality.
In the realm of electrical engineering, a disconnector or isolator switch is pivotal for ensuring complete de-energization of an electrical circuit during maintenance or service activities. Primarily used for circuit separation, these switches are integral to electrical distribution systems and substations, ensuring that machinery is safely powered down for adjustments or repairs. Disconnectors can be operated manually or by motor and are often paired with an earthing switch to guarantee that isolated sections are safely grounded, thus safeguarding both equipment and personnel. High-voltage isolation switches are critical within electrical substations, enabling the isolation of apparatus such as circuit breakers, transformers, and transmission lines for maintenance purposes. While disconnectors are not typically used for routine circuit control, they provide essential safety isolation. Unlike load switches and circuit breakers, disconnectors are designed without arc suppression mechanisms, meaning they function as off-load devices with minimal breaking capacity. Thus, they are intended to be opened only after current interruption by another control mechanism.
