AC HV Disconnect Switch
•summary:
1.GN30-12(D) disconnect switch is an indoor electric apparatus of rated voltage 12kV, designed for three-phase AC systems operating at 50/60Hz.
2.It is utilized for making, breaking, and transferring current in high voltage electric apparatus, specifically in scenarios with voltage presence but no load.
3.The switch is engineered with a rotary moving contact system, seamlessly integrated on the switchgear for effortless operation.
4.It is also designed for wall-through installation, ensuring versatile application.
In the realm of electrical engineering, a disconnector—also known as a disconnect switch or isolator switch—plays a crucial role in maintaining the safety standards of electrical circuits by completely de-energizing them, allowing for service and maintenance. Primarily used for breaking circuits, these switches are a staple in electrical distribution and substations where machinery requires the removal of its driving power source for adjustments or repairs. Disconnectors can be operated manually or through motorization and are often equipped with an earthing switch to safely ground the isolated section of the system, safeguarding both equipment and personnel. High-voltage isolation switches are indispensable in substations, facilitating the isolation of critical apparatus like circuit breakers, transformers, and transmission lines for maintenance procedures. While they are not intended for routine circuit control, their primary function is safety isolation. Unlike load switches and circuit breakers, disconnectors do not have mechanisms for electric arc suppression that occurs due to the interruption of high currents. Consequently, they are off-load devices with a significantly limited breaking capacity, intended to be operated only after current interruption by another control device.
