The grounding knife has the simple function of protecting personal safety, when people start to overhaul after closing the grounding knife, a sudden call is directly conducted into the ground to force the grounding knife to be in short circuit to cause tripping, and therefore the possibility of electric shock can be reduced. The resistance of human body is larger than the resistance of ground, that is, the principle that the current obtained by dividing the resistance is less is utilized, thereby greatly reducing the current from human body to ground. According to the tripping principle, when a single-phase fault occurs in a line, switches on two sides of the fault line are disconnected, but because electromagnetic coupling exists between a normal phase and the fault phase, secondary arc extinguishing is not facilitated, and in order to reduce secondary arc extinguishing, when the switches on the two sides are disconnected, an automatic device acts to immediately switch on the HSGS on the two sides, so that the function of quickly extinguishing the arc is achieved. At present, electric earthing knife devices used on high-voltage switch cabinets are common, but the structures are different, wherein electric transmission structures are usually realized by matching bevel gears, the force required by the transmission of the bevel gears is larger, so the requirement on a motor is higher, in addition, the internal structure of the transmission structure is also very exquisite, and the performance and the appearance of the whole product are influenced if the arrangement is unreasonable.
