Abstract

The utility model discloses a high-voltage equipment grounding tool and particularly relates to a grounding wire operating rod. The grounding wire operating rod comprises an operating rod (1) and a grounding clamp (2), wherein the grounding clamp (2) is connected with a grounding wire, the operating rod (1) and the grounding clamp (2) are connected with each other through a universal rotary joint (3), and the universal rotary joint (3) is mainly formed by matching a spherical inner plug (31) with an annular outer sleeve (32). The grounding wire operating rod can freely adjust the bending direction of the grounding clamp through the universal rotary joint so that the influence of an operating space is greatly reduced when a worker uses the grounding wire. The direction of the grounding clamp can be adjusted in advance directly according to the actual needs, and then the grounding clamp is directly hung and buckled on a line of tested equipment. In addition, the grounding wire operating rod has the advantages of simple structure, light weight and lower manufacturing cost.

Description

Ground wire operating lever

Technical field

The utility model relates to a kind of high-tension apparatus earthing tool, is specifically related to a kind of ground wire operating lever.

Background technology

In electric power system, for guaranteeing staff's safety, the installing earth connection is an important safety measure.High-voltage grounding wire can be divided into according to environment for use: indoor master-row type earth connection (JDX-NL) and outdoor line type earth connection (JDX-WS).Current master-row type earth connection (JDX-NL) commonly used is in use because action bars is long, narrow space in switch cubicle, and action bars usually is against on the cabinet door, causes the earth clip jaws to tilt and presss from both sides not in placely, and earth clip can not clamp busbar fully; Because press from both sides not in placely, operating personnel's operation easier is large, tends to spend a large amount of time repeatable operation, still can not reliable ground; Action bars can't move in cabinet, hinders staff's inconvenience of constructing; The master-row type earth connection (JDX-NL) used in cabinet passes through lever principle, Manual operation handle place pressure handle drives the insulating bar inside connecting rod depresses F type jaws, usually occur inner link to rupture, come off and lost efficacy, the situation that whole earth brace is scrapped, and complex structure, quality is heavier, inconvenient operation; Outdoor line type earth connection (JDX-WS) design mouth hanging operates easily, but because of the mouth hanging direction backward, on busbar, can only press from both sides left and right, so can't promote the use of at indoor busbar.

The utility model content

The purpose of this utility model is to provide a kind of ground wire operating lever, has solved current ground wire operating lever jaws direction and has fixed, and can't on the equipment narrow and small in operating space, fulfil assignment, and operation is the problem of inconvenience very.

For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of ground wire operating lever, comprise action bars and earth clip, described earth clip is connected with earth connection, described action bars and earth clip interconnect by Universal rotary connector, and described Universal rotary connector is mainly to be cooperatively interacted and formed by spherical interior plug and ring-shaped jacket.

Further technical scheme is, described action bars is formed by connecting by fastener by the pole that at least two-section can shrink step by step.

Further technical scheme is, described earth clip is U-shaped, in the earth clip of U-shaped from jaws to the folder end diminishing v-depression.

Further technical scheme is, described spherical interior plug is fixed on the end of action bars, and described ring-shaped jacket is fixed on the end of earth clip.

Compared with prior art, the beneficial effects of the utility model are: this ground wire operating lever can be by the bending direction of any regulated ground folder of Universal rotary connector, make the staff when using earth connection, greatly reduced by the impact of operating space, can directly be regulated the direction of earth clip in advance according to actual needs, then directly be buckled on the circuit of equipment under test; The utility model is simple in structure in addition, lightweight, and manufacturing cost is also lower.

The accompanying drawing explanation

The structural representation that Fig. 1 is the utility model ground wire operating lever.

Fig. 2 is the local enlarged diagram in A place in Fig. 1.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Fig. 1 and Fig. 2 show an embodiment of the utility model ground wire operating lever: a kind of ground wire operating lever, comprise action bars 1 and earth clip 2, described earth clip 2 is connected with earth connection, described action bars 1 and earth clip 2 interconnect by Universal rotary connector 3, and described Universal rotary connector 3 is mainly to be cooperatively interacted and formed by spherical interior plug 31 and ring-shaped jacket 32.

According to another embodiment of the utility model ground wire operating lever, described action bars 1 is formed by connecting by fastener by the pole that at least two-section can shrink step by step.

Another embodiment according to the utility model ground wire operating lever, described earth clip 2 is U-shaped, in the earth clip 2 of U-shaped, from jaws to the diminishing v-depression in the folder end, earth clip 2 can directly buckle at the circuit of equipment under test capablely like this, and its v-depression can utilize the fastening circuit of conducting oneself with dignity.

According to another embodiment of the utility model ground wire operating lever, described spherical interior plug 31 is fixed on the end of action bars 1, and described ring-shaped jacket 32 is fixed on the end of earth clip 2.
