Background

When the isolating switch is in a separated position, the contacts have insulation distance meeting the specified requirements and obvious disconnection marks; a switching device capable of carrying current in normal loop conditions and current in abnormal conditions (e.g., short circuit) for a specified period of time when in the closed position. The isolating switch (commonly called as "knife switch") generally refers to a high-voltage isolating switch, generally referred to as an isolating switch for short, is the most used electrical appliance in high-voltage switching electrical appliances, and has a relatively simple working principle and structure, but has a high requirement on working reliability due to large usage amount, and has a relatively large influence on the design, establishment and safe operation of a substation and a power plant. The main characteristic of the isolating switch is that it has no arc-extinguishing capability, and can only open and close the circuit under the condition of no load current. The isolating switch is used for each stage of voltage, is used for changing circuit connection or isolating lines or equipment from a power supply, has no current-breaking capacity, and can be operated only after other equipment is used for disconnecting the lines. Generally, an interlocking device for preventing misoperation when a switch is loaded is arranged, sometimes a pin is needed to prevent the switch from being disconnected under the action of magnetic force of a large fault, the isolating switch needs to be periodically overhauled, and the most frequently used tool for overhauling the isolating switch is an auxiliary tool for overhauling the isolating switch.
