Abstract
The utility model provides an environmentally-friendly intelligent grounding box which comprises a box body, grounding copper bars and multiple sheath protectors. The grounding copper bars include a horizontal copper bar and a vertical copper bar. Coaxial cables and a grounding connection pressure plate are disposed inside the box body. Multiple lead-in wire sleeves are disposed at a lower end of the box body. An upper end of the vertical copper bar is connected with the horizontal copper bar, and a lower end of the vertical copper bar is connected with one lead-in wire sleeve. The sheath protectors are disposed on a lower side of the horizontal copper bar. Upper ends of the coaxial cables are connected with the sheath protectors, and lower ends of the coaxial cables are connected with the lead-in wire sleeves. Outer layer conductor terminals are disposed on middle parts of the coaxial cables, and are connected with the vertical copper bar through the grounding connection pressure plate. Since the environmentally-friendly intelligent grounding box adopts the form of integrating direct grounding and protection grounding, needed quantity of and the space for grounding boxes are substantially reduced, the cost is reduced, and at the same time, the safety performance of work of cable circuits is improved.
Description
Technical field
The utility model relates to a kind of cable connection equipment, especially a kind of environment-friendly intelligent grounding box.
Background technology
Electric power is the essential resource of country, and grounding box is the important accessory on high-tension cable, is the key equipment that guarantees that electric power conveying is normally carried out.Traditional grounding box adopts the structure of cross interconnected pressing plate and single core running line, needs two grounding boxes to use together during installation, is responsible for direct ground connection for one, another protective earthing, make electric power carry can safety carrying out.But so, just make to install the needed quantity of grounding box and become how large with the change of occupation of land space, improved cost; The wave impedance of single core running line is larger simultaneously, makes overvoltage level higher, and cable easily damages, and causes State Grid to carry and goes wrong and serious economic loss.
Utility model content
The purpose of this utility model is in order to solve grounding box poor stability, the problem that cost is high.
In order to overcome the above problems, the utility model provides a kind of environment-friendly intelligent grounding box, comprise casing, grounding copper bar and a plurality of sheath protector, described grounding copper bar comprises horizontal copper bar and vertical copper bar, the inside of described casing is also provided with coaxial cable and grounding connection pressing plate, the lower end of described casing is provided with a plurality of entrance bushings, the upper end of described vertical copper bar connects horizontal copper bar, the lower end of described vertical copper bar connects entrance bushing, described sheath protector is installed on horizontal copper bar downside, the upper end of described coaxial cable is connected with sheath protector, the lower end of described coaxial cable is connected with entrance bushing, the middle-end of described coaxial cable is provided with outer contact terminal, described outer contact terminal links together by grounding connection pressing plate and vertical copper bar.
In described entrance bushing, be provided with insulated enclosure layer.
A kind of environment-friendly intelligent grounding box described in the utility model, comprise casing, grounding copper bar and a plurality of sheath protector, described grounding copper bar comprises horizontal copper bar and vertical copper bar, the inside of described casing is also provided with coaxial cable and grounding connection pressing plate, the lower end of described casing is provided with a plurality of entrance bushings, the upper end of described vertical copper bar connects horizontal copper bar, the lower end of described vertical copper bar connects entrance bushing, described sheath protector is installed on horizontal copper bar downside, the upper end of described coaxial cable is connected with sheath protector, the lower end of described coaxial cable is connected with entrance bushing, the middle-end of described coaxial cable is provided with outer contact terminal, described outer contact terminal links together by grounding connection pressing plate and vertical copper bar.The utility model, by the form of direct ground connection and protective earthing one, makes to install the needed quantity of grounding box and space and has greatly reduced, and has saved cost, has improved the fail safe of cable circuit work simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of environment-friendly intelligent grounding box described in the utility model.
1, casing; 2, grounding copper bar; 21, horizontal copper bar; 22, vertical copper bar; 3, sheath protector; 4, coaxial cable; 41, outer contact terminal; 5, grounding connection pressing plate; 6, entrance bushing.
Embodiment
Below in conjunction with accompanying drawing, a kind of environment-friendly intelligent grounding box described in the utility model is further described.
As shown in fig. 1, a kind of environment-friendly intelligent grounding box of the present embodiment, comprise casing 1, grounding copper bar 2 and a plurality of sheath protector 3, grounding copper bar 2 comprises horizontal copper bar 21 and vertical copper bar 22, the inside of casing 1 is also provided with coaxial cable 4 and grounding connection pressing plate 5, the lower end of casing 1 is provided with a plurality of entrance bushings 6, vertically the upper end of copper bar 22 connects horizontal copper bar 21, vertically the lower end of copper bar 22 connects entrance bushing 6, sheath protector 3 is installed on horizontal copper bar 21 downsides, the upper end of coaxial cable 4 is connected with sheath protector 3, the lower end of coaxial cable 4 is connected with entrance bushing 6, the middle-end of coaxial cable 4 is provided with outer contact terminal 41, outer contact terminal 41 links together by grounding connection pressing plate 5 and vertical copper bar 22.Owing to adopting the outer contact terminal 41 and the mode that grounding copper bar 2 is connected of coaxial cable 4, make outer contact form direct ground connection, inner conductor forms the form of protective earthing.This kind of environment-friendly intelligent grounding box becomes the grounding box of direct ground connection and protective earthing one; with respect to traditional grounding box; half this kind of environment-friendly intelligent grounding box of quantity only need to be installed and just can reach job requirement, save a large amount of installing spaces and cost.Simultaneously because coaxial cable 4 is less than the wave impedance of common single core running line, thereby reduce overvoltage level, made cable be not easy to burn out, improved fail safe.
In the present embodiment, in described entrance bushing 6, be provided with insulated enclosure layer.Can anti-sealing enter grounding box cable is caused damage, guaranteed the normal work of cable circuit.
The utility model is not limited to above embodiment and conversion.
