And earth brace, the energy of No. two elastic components 8 storage is discharged, anti-off board 4 is set back, the closure of earth wire is completed, prevents
Ground line goes offline；And it is grounded fair line slot 2a and trunking 2b that two sides arrive at " heart " type engaging slot 2 along two fair line slot 2a
Public domain, then ground line is constantly placed in along trunking 2b, at this moment the ground line is by holding between fair line slot 2a and trunking 2b
The " V " shape limiting section 3,3 ' for holding the formation of portion 1 limits, and the fair line slot 2a and trunking 2b of two engaging slots 2 are that inversion is arranged, and two
The limiting section 3,3 ' of engaging slot 2 is opposite to be deviated, thus after being grounded by two limits of limiting sections 3,3 ', even if ground line one end
It slides to the public domain of fair line slot 2a and trunking 2b, is in trunking 2b in the ground line foundation of other side engaging slot 2,
And no matter how move, there is limiting section 3,3 ' to play the limit of earth wire, thus ground line when can realize maintenance overhaul
Fast Installation, maintenance finish needs overhaul ground line by aforesaid operations reverse operating.
Using the thread-off prevention line rapid grounding line apparatus in substation's outage installation maintenance, it can be rapidly assembled and disassembled and connect
Ground wire, and it is grounded the smooth entrance in holding section, strength is more saved compared to the operation of existing grounding wire connector, improves power transformation peace
The safety of dress maintenance operation maintenance personnel；In addition, the quick coupling can be used cooperatively with existing thread earthing bar, by the fast quick access
When head installation to thread earthing bar, the merging of achievable ground line and the motion-promotion force of anti-off board 4 are provided, and do not need to connect in merging
Manpower applies lower pressure to anti-off board 4 when ground wire, and the screw thread of the quick coupling and earth brace can form the limit to anti-off board 4 again
Position, can facilitate anti-off board 4 to adjust to suitable position and carry out ground line merging, be placed in ground line in trunking 2b regardless of
How activity is limited always in the holding section of 4 bottom of anti-off board, is fallen off so as to avoid what is be grounded in special circumstances.
Embodiment 2: referring to Fig. 6, Fig. 7, Fig. 8 and Fig. 9
Compared with Example 1, difference is that the end face of grip part 1 is oblique, and the end face is the opening of engaging slot 2 place
Face, this setup make ground line that can need to manually adjust along the smooth entrance fair line slot 2a in the inclined face in grip part 1
The case where reduce, thus reduce installation and removal ground line the labour used time, improve work efficiency.
Embodiment 3: referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Figure 11
Compared with embodiment 1 or embodiment 2, difference is that 4 lower part of anti-off board in grip part 1 is also fixed with loading plate
11, loading plate 11 is equipped with through-hole 11a, and No.1 elastic component 5 passes through through-hole 11a, can normally push, and does not influence the merging of ground line
With the reset of anti-off board 4, preset clearance between the loading plate 11 and anti-off board 4, so that the gap can be used for when anti-off board 4 pushes
Accommodate ground line；Loading plate 11, which is arranged, can reduce the scope of activities of 4 Bottom ground line of anti-off board, so that ground line is on holding section
It can constantly tighten, 3,3 ' earth wire of the limiting section fixing of the opposite offset of two " V " types is more compact, connects so as to secondary raising
Ground wire anti-dropout effect.
