Embodiment 1
[0042] The invention proposes a grounding device applied in the field of electric power, which can connect the grounding wire to the grounding bar without a discharge gap, avoiding poor grounding and affecting the grounding effect at the node, and at the same time, the groove structure makes the grounding wire The connection between the same ferrule is tighter to avoid the occurrence of discharge between conductors, such as figure 1 , figure 2 , image 3 As shown, a grounding bar 9 is provided, and at least one wiring hole 8 is arranged on the grounding bar 9, and a wiring device is arranged on the wiring hole 8, and the wiring device includes a wire hoop 13, a wire protection slot 12 , the side wall of the wire hoop 13 is penetrated with a wire fixing member 16, and the end of the wire fixing member 16 located in the wire hoop 13 is provided with a wire protection groove 12, and the wire protection groove 12 is a groove structure, And on the back side of the groove 14 of t...
Embodiment 2
[0044] This embodiment is further optimized on the basis of the above-mentioned embodiments. Further, in order to better realize the grounding device of the present invention, the wire protection groove part and the wire fixing part 16 can be fixed by screwing, and the grounding lead squeeze, such as figure 1 , figure 2 , image 3 As shown, the following setting method is adopted in particular: the thread fixing member 16 is a screw structure, and the connecting hole 15 is provided with an internal straight thread, the thread fixing member 16 adopts a thread structure of an external straight thread, and the connecting hole 15 adopts a built-in The thread can effectively compress the grounding lead wire, and improve the connection strength between the wire fixing member 16 and the wire protection groove member 12, so that the service life of the whole structure is increased by at least 45%.
Embodiment 3
[0046] This embodiment is further optimized on the basis of any of the above-mentioned embodiments. Further, in order to better realize the grounding device of the present invention, the grounding lead can be pressed more tightly, such as figure 1 , figure 2 , image 3 As shown, the following arrangement is adopted in particular: an elastic buffer 11 is sleeved on the wire fixing member 16, and the elastic buffer 11 is placed between the nut head 10 and the wire hoop 13 of the wire fixing member 16, The elastic buffer 11 is set between the nut head 10 and the mushroom 13, which can further improve the connection tightness between the wire fixing member 16 and the wire hoop 13, and can effectively prevent the grounding lead from falling off from the wire hoop 13. , so that the grounding effect is substantially improved; the grounding lead is limited in the wire ferrule by the wire guard groove with grooves, and is tightened by the wire fixing part, so that the grounding lead ...

Abstract
The invention discloses a grounding device and a grounding method applied to the power field, and aims at solving the problem of bad grounding in the prior art. The grounding device is provided with a grounding bar, wherein the grounding bar is provided with at least one wiring hole; a wiring device is arranged on each wiring hole and comprises a wire ferrule and a wire protecting groove part; a wire fixing part is arranged on the side wall of each wire ferrule in a penetrating manner; a wire protecting groove part is arranged at the end, in the corresponding wire ferrule, of each wire fixing part, and is in a groove structure; a connection hole is formed in the back surface of a groove of each wire protecting groove part; and each wire fixing part is detachably arranged in the corresponding connection hole. The method comprises the following steps: putting each wire ferrule into the corresponding wiring hole; enabling each wire fixing part to pass through corresponding elastic buffer part and wiring hole at the lower part of the grounding bar and fixing the corresponding wire ferrule on the grounding bar; enabling a grounding lead to pass through the corresponding wire ferrule, laminating the groove of each wire protecting groove part on the corresponding grounding lead; and screwing each wire fixing part into the connection hole of the corresponding wire protecting groove part, tightening up the wire fixing part and making the grounding lead clung to the inner wall of the corresponding wire ferrule.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to a grounding device and a grounding method applied in the power field. Background technique [0002] The power system is a unified whole that converts primary energy into electrical energy, which is composed of equipment and technologies such as power generation, power transformation, power transmission, power distribution, power supply, and power consumption. After the electric energy is generated by the power plant, it is sent to the power user side through the high-voltagetransmission network through the substations at all levels, and then supplied to the user through the distribution network. For the needs of work and safety in the power system, it is often necessary to connect some parts of the power system and its electrical equipment to the earth, which is grounding. [0003] The "ground" in the power system refers to the earth conductive substance whose potential a...
