Abstract
The utility model relates to the technical field of electrical work safety, and particularly relates to a short circuit grounding device used for overhead line maintenance, which comprises an operation rod (2). The end part of the operation rod (2) is fixedly connected with a hook (1); the root part of the hook (1) is fixedly connected with a connection copper plate (6); the upper part of the connection copper plate (6) is fixedly connected with a copper nose (8) at the end part of a grounding line (3); and the grounding line part located behind the copper nose (8) is fixed on the surface of the connection copper plate (6) via a plurality of shroud rings (9) arranged at intervals. According to the grounding line connection device used for overhead line maintenance, strands of the grounding line can be effectively prevented from being broken, the borne carrying capacity of the grounding line can be ensured, the grounding line can be well protected, assembly and disassembly are safe and quick, and the grounding line can be effectively prevented from being damaged.
Description
Technical field
The utility model relates to work about electric power safe practice field, particularly a kind of overhead transmission line maintenance short-circuit grounding device.
Background technology
The temporary ground wire using in electric equipment is the important technique measure that ensures electrical production safety; when operating personnel work on electric equipment; the direction envelope hanging earthing conductor of likely sending a telegram here; make the operating personnel that work in earth connection protection range not be subject to the equipment threat of incoming call suddenly, effectively protected the operating personnel's that work personal safety on electric equipment.
At present, in the time of system for distribution network of power overhead transmission line interruption maintenance, short-circuit grounding device used is made up of insulating bar, hook and ground connection copper cash, and insulating bar and hook are connected, and ground connection copper cash is connected to hook afterbody with screw.But find in maintenance process, earth connection of the prior art in use, because ground connection copper cash is connected to hook afterbody with screw, ground connection copper cash easily self is excessively wound around even existing disconnected burst phenomenon, if field personnel is above shaft tower, by rotating insulating bar, ground connection copper cash is carried out to unwinding, extremely inconvenient; After ground connection copper cash twists off, the ampacity that ground connection copper cash bears diminishes, and the cross section of earth connection does not reach the standard-required of safety regulations, and circuit has down power transmission, self power generation, electrification seasonable like this, and earth connection just can not play the staff's that keeps the scene intact effect.
Summary of the invention
The problems referred to above that the utility model exists in order to solve existing short-circuit grounding device, provide a kind of novel overhead transmission line maintenance short-circuit grounding device.
The utility model is to adopt following technical scheme to realize:
A kind of overhead transmission line maintenance short-circuit grounding device, comprises joystick, and the end of described joystick is fixedly connected with hook; Described hook afterbody is fixed with connection copper coin, and the copper nose of described connection copper coin top and earth connection end is connected, and the earth connection part being positioned at after copper nose is fixed on and is connected copper coin surface by spaced some shroud rings.
Adopt after above-mentioned structure; owing to being provided with connection copper coin between hook and earth connection; the earth connection part being positioned at after copper nose is fixed on and is connected copper coin surface by spaced shroud ring; alleviate suffered bending power, the distortion power of grounding wire connector part by connecting copper coin; effectively avoid earth connection to occur disconnected thigh, the phenomenon being wound around; ensure the ampacity that earth connection bears, earth connection is played a very good protection, also made site operation personnel's construction safety obtain effective guarantee.
Further, one group comprises three one control levers, and described every one control lever connects an earth connection by hook respectively, and described three earth connection afterbodys extend a total earth connection by anti-losing after spring housing intersects, and described total earth connection end is connected with grounding head.For preventing earth connection damage, install additional in earth connection intersection and anti-ly lose spring housing, utilize the tension force of spring housing to control copper cash and do not occur dead angle and breakage.
The utility model is reasonable in design, provides one can make ground connection copper cash the end of a thread and hook firm and reliable connection, ensures the ground wire connecting device of maintainer's easy construction, safety.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of overhead transmission line maintenance short-circuit grounding device, as shown in Figure 1, comprises joystick 2, and the end of described joystick 2 is fixedly connected with hook 1; Described hook 1 afterbody is fixed with and connects copper coin 6, the copper nose 8 of described connection copper coin 6 tops and earth connection 3 ends is connected, the earth connection part being positioned at after copper nose 8 is fixed on and is connected copper coin 6 surfaces by spaced some shroud rings 9, as shown in Figure 2, described connection copper coin 6 by bearing pin 7 with link up with 1 afterbody and be connected, described copper nose 8 by bearing pin 7 be connected copper coin 6 and connect.
Three earth connection 3 afterbodys extend a total earth connection 10 by anti-losing after spring housing 5 intersects, and described total earth connection 10 ends are connected with grounding head 4.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
