Disconnector Switches - The "Safety Gates" for Power Maintenance
Date:2025/4/25 0:00:00 Click:42
In power systems, disconnector switches cannot interrupt high currents but are indispensable for maintenance work. Their primary role is to isolate circuits, ensuring absolute safety for workers during repairs.
Unlike circuit breakers, disconnectors lack arc-extinguishing capabilities and must only be operated when the circuit is de-energized. For instance, during substation maintenance, workers first open the circuit breaker and then operate the disconnector to create a visible break, preventing accidental re-energization.
Modern disconnectors are evolving toward motorized operation and remote control, with some advanced models equipped with sensors to monitor contact status in real time, improving grid reliability.
