Description

Telescopic protective earth line apparatus
Technical field
The utility model relates to power circuit maintenance auxiliary equipment, specifically is a kind of telescopic protective earth line apparatus that is applied to insulated static wire inspection, upkeep operation.
Background technology
The power circuit operating personnel is when carrying out power circuit inspection or maintenance, check or upkeep operation insulated static wire and gold utensil, the ground wire insulator, the inspection in gap and overhaul essential, and insulated static wire often has the high induced voltage of volts up to ten thousand, cause the accident of loss of life or personal injury also to happen occasionally owing to touch induced electricity in the electrical network, so, State Grid Corporation of China's " electric power safety working regulation " (power circuit part) 5.4.3 bar strict regulations: insulated static wire should be considered as electrified body, distance between operating personnel and the insulated static wire should be less than 0.4 meter, on insulated static wire during operation, use earth connection or individual security personnel's line with its reliable ground or adopt the equipotential mode to carry out as need.
In the upkeep operation of reality, during operation, the staff often adopts earth connection (claiming little ground wire again) just to carry out work behind its reliable ground on insulated static wire.Through the long-term use to existing grounding wire device, the staff will have grounding wire device place not fully up to expectations now and be summarized as follows:
1,, the effective and safe distance between operating personnel and the insulated static wire is necessarily guaranteed greater than 0.4 meter, general long 1.1 meters of the action bars of existing grounding wire device in order to guarantee operating personnel's safety; Though the effective and safe distance has had assurance, but the operating personnel carries the 1.1 meters long small connect ground line apparatus iron tower more than 30 meters up and down, or on cross-arm, move, or up and down during the line bracket platform, because of clearance space between iron tower tower material limited, there are small connect ground line apparatus and tower material case of collision, cause the operating personnel when shaft tower up and down, to have unnecessary psychological burden, personal safety is easily formed very big harm;
2, when the operating personnel tears the small connect ground line apparatus open at extension, because when the operating personnel tears the overlap joint insulated static wire open at application small connect ground line apparatus action bars extension, the angle of action bars and insulated static wire can not guarantee into 90 ° of right angles, certain gradient is always arranged, the earthing clamp of small connect ground line apparatus adopts presses tongue molded lines folder, handle by rotary manipulation bar bottom makes pressure tongue wire clamp clamp/unclamp insulated static wire, troublesome poeration, after pressing the tongue wire clamp to clamp insulated static wire, action bars is overlapped on the ground wire supporting tower material has difficulties, not easy to operate, and operate dangerously, can't definitely guarantee the personal safety the when operating personnel operates;
3, existing small connect ground line apparatus action bars entire body is a salmon pink, end hand grip is with long 240 millimeters black insulation plastic cement overcoat, no safe mark rank is reminded, cause when operating personnel's extension is torn the small connect ground line apparatus open, the coverage of ignorance self and insulated static wire does not reach the human body of " safety " requirement and the effective and safe distance of insulated static wire easily.
Summary of the invention
The utility model is difficult for carrying of solving that existing grounding wire device exists, operation inconvenience, lack problem such as safe warning banner, and a kind of telescopic protective earth line apparatus is provided.
The utility model is to adopt following technical scheme to realize: telescopic protective earth line apparatus, comprise that the top is provided with the soft copper earth connection that the insulating bar of binding post, an end are connected with binding post, be fixed with wire clamp on the binding post, the other end of soft copper earth connection is fixed with and is used for and the fixing fixture of high-voltage line Tata material, described wire clamp constitutes along the binding post axial restraint and over against, the semicircle intermediate plate that separate to be provided with by two, form overhead ground wire between the two semi-circular intermediate plate free ends and import and export, and two semi-circular intermediate plate free ends are parallel or be outer Eight characters shape; Described insulating bar for by inner sleeve, be placed in the outer middle sleeve of inner sleeve, be placed in the telescopic action bars that the outer outer tube of middle sleeve constitutes, and inner sleeve and middle sleeve bottom are respectively arranged with and are used for and middle sleeve top, the fixing detent mechanism in outer tube top.The positioning and fixing structure that the structure of described detent mechanism can adopt existing telescopic alpin-stock to adopt.
The design of telescopic action bars makes steps on the tower personnel when carrying grounding wire device, inner sleeve and middle sleeve can be built in the outer tube, make the entire length of grounding wire device shorter relatively, conveniently step on the tower personnel and carry iron tower up and down, meet the ergonomics design concept, alleviated and stepped on tower personnel anti-collision mental handicape, fundamentally improved staff's security performance conscientiously;
When the operating personnel implements to hang built vacant lot line at the ground wire rack platform, at first the fixture and the high-voltage line Tata material of grounding wire device soft copper earth connection end are fixed, and make the telescopic action bars of grounding wire device launch the location, hand makes telescopic action bars then, the overhead ground wire of wire clamp on its top binding post is imported and exported towards overhead ground wire, the application of force makes overhead ground wire import and export via the overhead ground wire of wire clamp and places between the two semi-circular intermediate plates, the action bars bottom is overlapped on the ground wire supporting tower material to get final product at last; During dismounting, make the action bars bottom break away from ground wire supporting tower material, the application of force makes overhead ground wire be imported and exported to deviate to get final product by the overhead ground wire of wire clamp.Simple to operate, convenient, save worry, it is convenient that action bars bottom overlap joint ground wire supporting tower material is implemented, make the operating personnel can attentively note disconnecting in the procedure operation of ground wire device, can effectively prevent the generation of accident, unsafe conditions, improved the efficient of inspection and service work at extension.
In addition, scribble the redness that characterizes harmful grade, the green that characterizes dangerous other yellow of level and characterize level of security by the top to the bottom segmentation on the insulating bar, and the length of red color segment is 0.4 meter on the insulating bar, and the insulating bar subscript is marked with concrete size.Improve the awareness of safety of stepping on the tower operating personnel effectively.Make the operating personnel on the concrete operations instrument, quantize value, can effectively remind the operating personnel to notice that conscientiously overhead ground wire has electricity, and should carry out safety operation by specification requirement and relative program.
The utility model is simple and reasonable for structure, and is easy to operate, is easy to carry, and safe warning banner is eye-catching.
