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 with a rated voltage of 12kV, designed for three-phase AC 50/60Hz applications.
2. Skillfully engineered to make, break, and transfer current for high-voltage electric apparatus in environments with voltage but no load.
3. Innovatively designed with a rotary moving contact, seamlessly mounted on the switchgear for enhanced operational ease.
4. Incorporates wall-through installation, offering versatile and secure mounting options.
In the realm of electrical engineering, a disconnector, also known as a disconnect switch or isolator switch, plays a pivotal role in ensuring the complete de-energization of an electrical circuit for maintenance or service. These indispensable devices excel at circuit interruption and are frequently deployed in electrical distribution and substations, where machinery demands a cessation of its power source for adjustment or repair. Disconnectors can be operated manually or via motor, and are often equipped with an earthing switch to ground isolated sections, safeguarding both equipment and personnel. High-voltage isolation switches are crucial in electrical substations, enabling the isolation of vital apparatus such as circuit breakers, transformers, and transmission lines for maintenance purposes. While disconnectors are primarily intended for safety isolation rather than routine circuit control, their off-load design ensures minimal breaking capacity, as they are meant to be opened only after current interruption by a separate control device, unlike load switches or circuit breakers that manage electric arc suppression.
