AC HV Disconnect Switch
• Summary:
1. The GN30-12(D) disconnect switch is a robust indoor electric apparatus with a rated voltage of 12kV, suitable for three-phase AC 50/60Hz environments.
2. It excels in making, breaking, and transferring current for high voltage electric apparatus under no-load conditions, enhancing operational efficiency.
3. This switch features an innovative rotary moving contact, mounted conveniently on the switchgear for easy access and operation.
4. It is designed for wall-through installation, maximizing space efficiency and installation flexibility.
In electrical engineering, a disconnector, disconnect switch, or isolator switch is a vital component for ensuring complete de-energization of an electrical circuit during maintenance or service. Essential for safely breaking circuits, these devices are prevalent in electrical distribution and substations, where machinery must be safely isolated for repair or adjustment. Disconnectors can be either manual or motor-operated and may include an earthing switch to ground isolated sections, thereby safeguarding both equipment and personnel. High-voltage isolation switches are indispensable in substations, where they isolate critical apparatus such as circuit breakers, transformers, and transmission lines during maintenance. Disconnectors are designed solely for safety isolation and are not meant for routine circuit control. Unlike load switches and circuit breakers, they do not have arc suppression mechanisms, thus they operate off-load with minimal breaking capacity, intended to be opened only after another device interrupts the current.
