Technical Field
The utility model relates to an electrician's utensil, in particular to power wrench is installed and removed to transformer substation's power connection line.
Background
In the power industry, in order to prevent the maintenance equipment from being damaged by sudden incoming calls or induced voltage, the grounding wire for the maintenance equipment must be tightly connected with the ground, so that good grounding is ensured.
The grounding wire with the voltage grade of 110kV and above is formed by twisting a plurality of strands of soft copper wires, and is arranged at the high position of the switch blade indoors and outdoors by using an operating rod, so that the overall mass is heavier. The operator usually holds the bottom end of the operating rod with both hands to rotate the operating rod so as to realize the mounting and dismounting of the ground wire connector. When the maintenance operator works, the maintenance operator needs to wear the insulating gloves with both hands, but the maintenance operator is difficult to operate by a single person because the friction force between the insulating gloves and the operating rod is insufficient, and the diameter of the operating rod is small, so that the torque of pulling by a hand is small, and the operating rod is easy to slip.
The publication No. CN 108736184A discloses an adjustable auxiliary tool for quickly assembling and disassembling a grounding wire, wherein an elastic force of an extension clamp enables a fixed sleeve to clamp an operating rod, the fixed sleeve is driven by rotating an operating handle, the operating rod connected with the fixed sleeve is enabled to rotate, and the phenomenon of 'slipping' is difficult to avoid between the fixed sleeve and the operating rod in the actual rotating process due to the limited elastic force of the extension clamp.
Notice No. CN 211829897U discloses an auxiliary device for transformer substation's earth connection is installed and removed, and the device uses structures such as bearing, spring, pin, base, has reduced personnel's operating load, but the structure is more complicated, and can receive the place restriction in the actual operation process, and narrow and small space, place unevenness can't use.

An object of the utility model is to the above-mentioned defect among the prior art, a power wrench is installed and removed to transformer substation's earth connection is provided, simple structure, convenient operation, and also can use in narrow and small space.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: a power-assisted wrench for mounting and dismounting a grounding wire of a transformer substation comprises a left half ring, a right half ring, a fastening bolt and a handle; the left half ring and the right half ring are connected through the fastening bolt to form a clamping ring; the left half ring and the right half ring are respectively fixed with one handle.
Furthermore, the left half ring comprises a ring body and a connecting sheet, and the connecting sheet is fixed at two free ends of the ring body; the structure of the right semi-ring is the same as that of the left semi-ring.
Furthermore, the connecting sheet is provided with a connecting hole; and the two connecting sheets of the left half ring are connected with the two connecting sheets of the right half ring through fastening bolts.
Furthermore, one connecting piece of the left half ring is hinged with one connecting piece of the right half ring, and the other connecting piece of the left half ring is connected with the other connecting piece of the right half ring through a fastening bolt.
Further, the fastening bolt is a wing bolt or a bolt using a wing.
Furthermore, the power-assisted wrench for assembling and disassembling the grounding wire of the transformer substation also comprises a friction pad; the inner side walls of the left half ring and the right half ring are respectively provided with the friction pads.
Further, the friction pad is a rubber pad.
Compared with the prior art, the utility model has the advantages of:
the utility model discloses a power wrench for mounting and dismounting a grounding wire of a transformer substation comprises a left half ring, a right half ring, a fastening bolt and a handle, wherein the left half ring and the right half ring are connected through the fastening bolt to form a clamping space so as to clamp a grounding wire operating rod, and then the assembly and disassembly of a butt-joint electric wire are realized by rotating the handle, so that the rotating torque of the operating rod is increased, the speed of mounting and disassembling the grounding wire is increased, and the power wrench is simple in structure and convenient to operate; simultaneously and utility model's helping hand spanner overall structure is less, can use in narrow and small space.
