In the operation and maintenance process of the hydropower station, as the volume of part of low-voltage equipment is smaller, the internal space of the low-voltage equipment is smaller, but a large number of components and parts and charged parts are stacked, and when the equipment needs to be overhauled, the existing short-circuit grounding wire has the problems of difficult installation and insufficient installation space; in addition, the installation process is easy to touch the electrified part due to the fact that the space is insufficient and the operation cannot be standardized; because ordinary short circuit earth connection is bulky, self carries three-phase insulating bar mutual interference to can't effectively firmly install, have very big potential safety hazard.
An object of the utility model is to provide a short circuit earth connection of separable insulating bar after the installation. The insulating operating rod can be quickly disassembled, and the size of the short circuit grounding wire is reduced.
The utility model discloses a technical scheme: a short circuit grounding wire capable of separating an insulating operation rod after installation comprises the insulating operation rod, wherein the insulating operation rod comprises a connector, and a hollow rod is arranged at the lower part of the connector; spring buckles connected by springs are arranged on two sides of the connector, insulated wires are arranged on the inner sides of the spring buckles, the insulated wires are connected with a connecting rod positioned at the lower end of the hollow rod through a rotating cylinder positioned in the middle of the springs, and an operation knob is arranged on one side of the connecting rod; the upper end of the insulating operation rod is provided with a grounding device.
In the short-circuit grounding wire with the separable insulated operating rod after being installed, the grounding device comprises a wire clamp, one side of the wire clamp is provided with a grounding wire, and the lower part of the wire clamp is provided with a connecting sleeve corresponding to the connecting head.
In the short-circuit grounding wire capable of separating the insulated operating rod after being installed, the wire clamp comprises a fixed jaw, and an inclined movable jaw is arranged at the lower part of the fixed jaw.
In the short-circuit grounding wire with the detachable insulated operating rod installed, the connecting rod is perpendicular to the axis of the hollow rod.
In the short-circuit grounding wire with the separable insulated operating rod after being installed, the connector is internally provided with a guide groove perpendicular to the axis of the hollow rod, two ends of the guide groove are provided with openings with diameters smaller than that of the guide groove, and the spring buckle is in a step shape corresponding to the guide groove and the openings.
Compared with the prior art, it can make the insulating operation stick can be convenient pull down from earthing device through the motion of operation knob control spring buckle, has reduced the volume of earth connection, avoids earth connection self to carry mutual interference when the action bars is installed for earth connection wire clamp can effectively swiftly firmly install on maintenance equipment, has ensured operating personnel safety, this practical structure retrencies, and stable performance is difficult for the trouble.
