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 an elite indoor electrical apparatus with a rated voltage of 12kV, designed for three-phase AC at 50/60Hz.
2. Ideal for HV electric apparatus, it facilitates current interruption and transfer when voltage is present but no load is engaged, ensuring seamless operation.
3. This switch features an innovative rotary moving contact, conveniently mounted on the switchgear for effortless application.
4. Additionally, it incorporates a wall-through installation method, enhancing its adaptability and ease of use.
In the realm of electrical engineering, a disconnector, also known as a disconnect or isolator switch, is pivotal for ensuring complete de-energization of an electrical circuit during service or maintenance. Functioning solely to break the circuit, these essential devices are prominently utilized in electrical distribution and substations, where precise machinery operation requires the removal of power sources for adjustments or repairs. Disconnectors may 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 isolator switches play a crucial role in electrical substations, facilitating the isolation of critical apparatus like circuit breakers, transformers, and transmission lines for maintenance purposes. Primarily designed for safety isolation rather than routine circuit control, disconnectors differ from load switches and circuit breakers by lacking arc suppression mechanisms, thus categorizing them as off-load devices with minimal breaking capacity. They are engineered to be opened only post current interruption by an alternative control device, underscoring their significant role in maintaining operational safety.
