Background
The isolating switch is used for mainly playing a role in safety isolation in a power grid. The circuit is switched on and off under no load, so as to achieve the purposes of power failure maintenance and circuit conversion. The isolating switch can reliably pass rated current in a closing state and can bear short-circuit current; in the opening state, an obvious isolation fracture with reliable insulation is formed, so that the line to be overhauled or segmented is isolated from the live line, and the safety of maintainers and line equipment is ensured. A disconnector is a type of high-voltage switch that cannot open and close a circuit under load because there is no special arc extinguishing device. But it has obvious disconnection point, which can effectively isolate the power; after the traditional isolating switch opens and closes the circuit, its main conducting part does not have self-locking function, still has the risk of safe accident after receiving external environment strength interference.
