Abstract
The utility model discloses a transformer station ground wire clamp and relates to the technical field of safety protection auxiliary tools for repairing transformer stations in a power system. The transformer station ground wire clamp comprises an insulated operating lever. A hoop is disposed on the top of the insulated operating lever. A stand pipe is fixedly connected with the upper part of a side of the hoop. A semicircular groove with an outward opening is disposed on the lower part of the stand pipe. The transformer station ground wire clamp is also equipped with a supporting rod movably connected with the hoop. The supporting rod comprises a rod portion and a connecting portion. The connecting portion comprises a pedestal. A stand rod is disposed on the top of the pedestal. A horizontal rod vertically fixed to the stand rod is disposed on the middle of the stand rod. The bottom of the pedestal of the connecting portion is connected with the rod portion. According to the transformer station ground wire clamp, the top of a conventional insulated operating lever is provided with the hoop and the supporting rod used in cooperation with the hoop. Therefore, the transformer station ground wire clamp facilitates hanging when a ground wire is installed and uninstalled overhead, prevents the insulated operating lever from falling, provides a pulling fulcrum, guarantees good contact of a ground wire and a wire, achieves convenient operation, safety, and reliability, and ensures safety in construction.
Description
Technical field
Safeguard protection aid technical field when the utility model relates to power system transformer substation maintenance.
Background technology
In electric power system; earth connection is as electric substation's alternating current-direct current equipment ground and thunder proof protection ground; safe operation to system plays an important role; high-voltage grounding wire is for circuit and Substation construction; for preventing from closing on the use that ensures safety when electrified body produces electrostatic induction electric shock or false switching, conventionally by insulating bar, wire clamp, short-circuit line, earth connection, earth terminal, conflux and press from both sides and earth clip forms.At the outdoor 35kV 10kV of transformer station bus all on shaft tower top, apart from ground 4-5 rice, the 35kV inlet wire or the 10kV that arrange 35kV transformer station at high level go out traditional thread binding, when dismounting ground wire, because of earth connection operating grip short, need articulate with insulating bar, but earth connection does not have the special insulating bar strong point, insulating bar ferrule can only be stuck in to wire and the insulating rod connecting portion of ground wire, when installing or pulling down, may drop, causing breaking ground wire even pounds and hurts sb.'s feelings, especially, there is no drop-down fulcrum, can not ensure that ground wire contacts with wire well, and grounding wire connector frequently rubs, frangibility, there is potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of substation grounding wire clamp, the support bar that is provided with anchor ear at the top of existing insulating bar and is used in conjunction with anchor ear, when convenient high-rise dress, dismounting ground wire, articulate, prevent that insulating bar from dropping, be provided with drop-down fulcrum, ensure ground wire and wire good contact, flexible and convenient operation, safe and reliable, ensure construction safety.
Technical solution adopted in the utility model is: a kind of substation grounding wire clamp, comprise insulating bar, and the top of described insulating bar is provided with anchor ear, and a upper lateral part of anchor ear is fixedly connected with standpipe, and the bottom of standpipe is provided with opening semicircle groove outwardly; Also be provided with the support bar being flexibly connected with anchor ear, described support bar comprises bar portion and connecting portion, and described connecting portion comprises base, and base upper end is provided with vertical rod, and vertical rod middle part is provided with perpendicular fixing horizon bar, and connecting portion base lower end is connected with bar portion.
Described connecting portion base is threaded with bar portion.
The connecting portion base of described support bar and bar portion peg graft.
Described anchor ear is stainless steel anchor ear.
The beneficial effect that adopts technique scheme to produce is: the utility model is provided with anchor ear on the top of insulating bar, also be provided with the support bar being flexibly connected with anchor ear, increase after support bar, form a drop-down fulcrum, both while having facilitated high-rise dress, dismounting ground wire, articulated, prevent that insulating bar from dropping, ensure again ground wire and wire good contact, eliminate safe hidden trouble.Anchor ear and support bar adopt movable connection method, and flexible and convenient operation is safe and reliable, has ensured construction safety.The utility model is simple in structure, easy to use, and cost is low, has good promotional value, is applicable to the construction of the high-rise earth connection of arranging 35kV transformer station.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, 1. insulating bar, 2. anchor ear, 3. standpipe, 4. groove, 5. bar portion, 6. connecting portion.
Embodiment
Referring to accompanying drawing 1, a kind of substation grounding wire clamp, comprises insulating bar 1, the top of described insulating bar 1 is provided with anchor ear 2, anchor ear 2 is stainless steel anchor ear, and a upper lateral part of anchor ear 2 is fixedly connected with standpipe 3, and the bottom of standpipe 3 is provided with opening semicircle groove 4 outwardly; Also be provided with the support bar being flexibly connected with anchor ear 2, described support bar comprises bar portion 5 and connecting portion 6, and described connecting portion 6 comprises base, and the upper end of base is provided with vertical rod, vertical rod middle part is provided with perpendicular fixing horizon bar, and the lower end of base is threaded or pegs graft with bar portion 5.When use, the vertical rod of support bar connecting portion is inserted in the standpipe 3 of anchor ear, then rotary supporting rod, make the horizon bar vertical with vertical rod be positioned at groove 4, so just can ensure that support bar passes through anchor ear 2 and is connected reliably with insulating bar 1, then hand-held supports bar bar portion 5, thus while facilitating high-rise dress, dismounting ground wire, articulate, effectively prevent that insulating bar from dropping.Increase after support bar, form a drop-down fulcrum, ensure ground wire and wire good contact, eliminate safe hidden trouble.The lower end of support bar connecting portion 5 bases is threaded or pegs graft with bar portion 5, adopts this dismantled and assembled connected mode, is convenient for changing the bar portion 5 of different length, easy to carry, can meet differing heights grounding wire mounting, tear requirement open.
