Abstract
The utility model relates to a short-circuit-proof type circuit grounding hook, which comprises a conductor and an insulating sheath, wherein the insulating sheath is composed of an upper sheath which is buckled on the upper portion of the conductor and a lower sheath which is fixedly adhered on the lower portion of the conductor. The short-circuit-proof type circuit grounding hook is characterized in that a swelling elastic insulating protective capsule is arranged corresponding to an earth point of the bottom of the lower sheath and the conductor, a long strip slot which can be threaded through a ground wire coupling hook is arranged on the bottom surface of the protective capsule, and a hollow cavity which can contain the ground wire coupling hook is arranged between the inner wall of the protective capsule and the conductor. The earth point of the short-circuit-proof type circuit grounding hook is arranged in the insulating sheath, can effectively reduce the circuit short-circuit failures, and can lower the circuit power off time due to the failures, thereby reducing the load loss and the circuit maintenance cost effectively, and the operation of hitching the ground wire coupling hook is very convenient.
Description
Technical field
The utility model relates to a kind of device power ground, specifically is a kind of short circuit protective line-to-ground hook.
Background technology
The ground connection hook is one of 10KV distribution insulated circuit important accessory commonly used.Because the needs of line outage when work hanging earthing conductor, mostly rationally be distributed with a plurality of bare spots on the insulated circuit and be used for hanging earthing conductor.The ground connection hook is for satisfying the line facility that this requirement is installed.The top of ground connection hook is nested with on the circuit after the peeling; The bottom of ground connection hook is for articulating the ring-type of butt hook; The insulating sleeve of ground connection hook is divided into two parts; Upper jacket, lower jacket.Described upper jacket is coated on the top of ground connection hook, and this upper jacket is removable fastening type.Described lower jacket is fixedly attached to ground connection hook bottom, and to be provided with bare spots at ground connection hook minimum point place be earth point, as shown in Figure 1, is used to articulate the butt hook of earth connection.
Though the ground connection hook of this form is simple in structure, easy to use, exists tangible deficiency: the earth point at ground connection hook minimum point place is exposed in the air, lacks protection, has reduced the line insulation level, causes individual event ground connection or phase fault easily.Tree growing is near lead and ground connection hook under line, or lodge cloth, colored ribbon on the circuit, birds situation such as nest on the electric pole that has the ground connection hook is easy to cause circuitry obstacles such as individual event ground connection or phase fault when taking place, if the scaffold of construction site etc. climbings framework is during near exposed ground connection hook, cause easily that not only obstacle reduces the fail safe of power circuit, reliability, the even more serious life security to personnel of will bringing threatens.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of short circuit protective line-to-ground hook, its earth point places within the insulating sleeve, effectively prevents the exposed short circuit obstacle that causes of earth point because of the ground connection hook, and eliminates the unsafe factor that it brings.
In order to address the above problem, the utility model by the following technical solutions: this short circuit protective line-to-ground hook, comprise conductor and insulating sleeve, wherein insulating sleeve is made up of the upper jacket on the top that is fastened on conductor and the lower jacket that is fixedly attached to the bottom of conductor; Described lower jacket bottom is made as the elastic insulated protection capsule of heaving with the earth point corresponding section of conductor, and the bottom surface of this protection capsule is provided with can be passed the rectangular of earth connection butt hook and crack; Be provided with the cavity that can hold the earth connection butt hook between the inwall of this protection capsule and the conductor.
The beneficial effects of the utility model are: its earth point places within the insulating sleeve, can effectively reduce the line short fault, reduces for some reason to hinder the line outage time of causing, thereby effectively reduces load loss and line maintenance expense; And it is also very convenient to articulate the operation of earth connection butt hook.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram,
Fig. 2 is a structural representation of the present utility model,
Fig. 3 is A-A view of Fig. 2,
Among the figure: 1 conductor, 2 lower jackets, 3 protection capsules, 4 crack, 5 cavitys, 6 earth points.
Embodiment
Shown in Fig. 2,3, this short circuit protective line-to-ground hook comprises conductor 1 and insulating sleeve, and wherein insulating sleeve is made up of with the lower jacket 2 that is fixedly attached to the bottom of conductor the upper jacket on the top that is fastened on conductor.Earth point 6 corresponding sections of these lower jacket 2 bottoms and conductor are made as the elastic insulated protection capsule of heaving 3, and the bottom surface of this protection capsule 3 is provided with can be passed the rectangular of earth connection butt hook and crack 4; Be provided with the cavity 5 that can hold the earth connection butt hook between the inwall of this protection capsule 3 and the conductor 1.
When needs ground connection, by insulating bar the butt hook of earth connection is withstood on and to crack on 4, and firmly can will crack and 4 back down, butt hook can enter in the cavity 5 and hang on the earth point 6 of conductor.Because the material of protection capsule 3 adopts resilient insulating material to make, so but 4 auto-closings that crack.So just avoided earth point 6 to be exposed in the air, thereby prevented because of the earth point 6 exposed faults such as short circuit that cause.
When extracing the butt hook of earth connection, by insulating bar the butt hook of earth connection to be taken from earth point 6, and butt hook is pulled out 4 from cracking, after butt hook took out, 4 auto-closings again cracked.
The same prior art of all the other technology.
Claims (1)
1, short circuit protective line-to-ground hook comprises conductor and insulating sleeve, and wherein insulating sleeve is made up of with the lower jacket that is fixedly attached to the bottom of conductor the upper jacket on the top that is fastened on conductor; It is characterized in that: described lower jacket bottom is made as the elastic insulated protection capsule of heaving with the earth point corresponding section of conductor, and the bottom surface of this protection capsule is provided with can be passed the rectangular of earth connection butt hook and crack; Be provided with the cavity that can hold the earth connection butt hook between the inwall of this protection capsule and the conductor.
