When Operating A High-voltage Disconnector, It Is Strictly Forbidden To Operate It Under Load.

During the use of High Voltage Disconnect Switch, it is strictly forbidden to perform splitting or combining operations under load. This type of equipment is designed to create a visible break point for maintenance isolation under no-load conditions.

Operating under load will generate electric arcs, current surges, and mechanical wear. Disconnect switches typically lack arc-extinguishing devices, and their contact spacing and structural design are not designed to handle load-bearing breaking currents and short-circuit currents. Therefore, if current continues to flow in the circuit during closing or opening, even if the voltage level is not high, it may trigger a localized electric arc, potentially leading to equipment damage or injury to operators.
