The Role Of High Voltage Isolating Switch
When the "electric tiger" is showing its power, ordinary people can only tremble? Don't panic! High Voltage Disconnect Switch is like a "safety gate" in the circuit, which can cut off the power supply at a critical moment and give maintenance personnel a way out. Today's dry goods will take you to unlock the hidden skills of the isolation switch. From household distribution boxes to high-voltage substations, it is the real "behind-the-scenes hero".
Core function ①: Physical isolation, "seal" live equipment
🔌 Life-saving talisman during maintenance
When the circuit needs maintenance, the isolation switch can completely disconnect the power supply and form a "visible disconnection point" between the live equipment and the area to be repaired. This physical isolation is equivalent to putting a seal on the circuit that says "Construction here, no power on", ensuring that maintenance personnel will not accidentally touch the live line.
💡 Applicable scenarios
Home: Disconnect the main disconnector before replacing the switch fuse
Factory: Cut off the main power supply when repairing high-voltage equipment
Substation: Isolate the upstream and downstream circuits before replacing the transformer
Core function ②: Switching operation, the power grid version of "The Great Shift of Heaven and Earth"
⚡ Free switching of dual busbars
In a dual-busbar power supply system, the disconnector can "switch" the circuit path "without feeling". For example, switch the running circuit from busbar A to busbar B to ensure the continuity of power supply while completing equipment maintenance.
