Abstract
The utility model provides a kind of earth connection attaching/detaching apparatus, earth connection attaching/detaching apparatus comprises sleeve and drive unit, described sleeve is made up of inner core, handheld tube, stationary magazine creel, described inner core is lined with elastic insulating layer, described fixing barrel casing is in inner core upper outside, and described handheld tube is enclosed within inner core lower outside; Described handheld tube can be rotated relative to inner core, has demarcation strip in the middle part of described inner core, cuff hoop on sleeve outside for tightening sleeve.Dismounting earth connection can be saved expended bodily strength, effectively control the time of dismounting earth connection, to the shortening whole operating time, promote safety management level.
Description
Technical field
The utility model relates to a kind of earth connection attaching/detaching apparatus.
Background technology
In the equipment maintenance work of transformer station, when equipment or circuit need interruption maintenance, for ensureing the safety of the person and equipment, all need can carry out maintenance work after stopping labour equipment adding hanging earthing conductor or the earthing switch blade that closes.The time length that earth connection hangs, directly have influence on whole operation and can complete in the given time whether smoothly.
The operation used in current transformer station and working earthing line, most employing duckbill conductor end, the principle of similar spanner, " stinging " copper bar or the cast lead-in wire of firmly rectangle, progressively tightening up by rotating insulating bar the object that duck bill hole reaches fixed conductor end with duckbill mouth.Also be same principle during dismounting earth connection.
The operation of mounting or dismounting earth connection seems and uncomplicated, at action need cost long time.For outdoor 110kV main transformer 10kV bus bridge, skilled person on duty installs a secondary main transformer 10kV side joint ground wire generally at least needs about 10-15 minute time, and the earth connection installing of 220kV then needs 20-30 minute usually.
The mounting or dismounting of earth connection are not only " technical profession ", are also " muscular labor ", and the earth connection weight that electric pressure is higher is larger, the earth connection of 220kV weighs tens of jin, lifts rear physical demands huge with the action bars of several meters long, and by muscle power restriction, operating time is longer, and failed probability is larger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device improving ground lead dismounting efficiency, and for this reason, the utility model provides following technical scheme:
A kind of earth connection attaching/detaching apparatus, earth connection attaching/detaching apparatus comprises sleeve and drive unit, and described sleeve is made up of inner core, handheld tube, stationary magazine creel, and described inner core is lined with elastic insulating layer, described fixing barrel casing is in inner core upper outside, and described handheld tube is enclosed within inner core lower outside; Described handheld tube can be rotated relative to inner core, has demarcation strip in the middle part of described inner core, cuff hoop on sleeve outside for tightening sleeve.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
Described cuff and stationary magazine creel consist of inseparable integral type cuff cylinder.Overall cuff cylinder ease of assembly, the independent separation sleeve of cuff is on stationary magazine creel, and cuff slides up and down, the good spacing of more difficult assurance.
Described handheld tube is provided with annular groove, places ball, make the relative rotation between handheld tube with inner core more smooth in described annular groove.
Described stationary magazine creel and inner core top have the adjustment stationary magazine creel and the inner core size that regulate vertical slot to regulate vertical slot adaptability, can fixed insulation bar more firmly.
Described drive unit contains motor and uses motor-driven tool heads, and described demarcation strip upper surface is provided with insulation skid resistant course, and demarcation strip lower surface has the groove matched with tool heads.
During operation, one holds motor, and one holds handheld tube, the inner core left-right rotation of operated tool headband moving sleeve, i.e. the insulating bar of insulating bar left-right rotation dismounting simultaneously.
Described cuff comprises cover cranse and handle, and described cover cranse is plugged on handle cam by connector; Button holds together handle, and cam height point props up cover cranse can tightening sleeve cranse, pulls open handle cam low spot and leaves cover cranse and can loosen cover cranse.
Owing to adopting the technical solution of the utility model, the beneficial effects of the utility model by: dismounting earth connection can be saved and expended bodily strength, effectively control the time of dismounting earth connection, to shortening whole operating time, lifting safety management level.

Embodiment
With reference to accompanying drawing, a kind of earth connection attaching/detaching apparatus, earth connection attaching/detaching apparatus comprises sleeve and drive unit, described sleeve is made up of inner core 1, handheld tube 2, stationary magazine creel 3, described inner core 1 is lined with elastic insulating layer, described stationary magazine creel 3 is enclosed within inner core 1 upper outside, and described handheld tube 3 is enclosed within inner core 1 lower outside; Described handheld tube 3 can be rotated relative to inner core 1, has demarcation strip 4 in the middle part of described inner core 1, and cuff 5 binds round on sleeve 3 outside for tightening sleeve.Namely described elastic insulating layer serves the effect of insulation, and also making insulating bar be fixed in sleeve has adaptive flexible adjustment.
Insulating bar inserts from described inner core 1 top, is lined with elastic insulating layer between described insulating bar and inner core 1, and cuff 5 binds round and above sleeve outside, insulating bar is fastened in sleeve.
Describedly hand-heldly be provided with annular groove 7, place ball in described annular groove, make the relative rotation between handheld tube with inner core more smooth.
State upper cartridge and have adjustment vertical slot, regulate adjustment stationary magazine creel 3 and inner core 1 size of vertical slot adaptability, can fixed insulation bar more firmly.
Described demarcation strip 4 upper surface is provided with insulation skid resistant course, and demarcation strip lower surface has the groove matched with tool heads.During operation, one holds motor 6, and one holds handheld tube 2, the inner core left-right rotation of operated tool headband moving sleeve, i.e. the insulating bar of insulating bar left-right rotation dismounting simultaneously.
Described cuff 5 comprises cover cranse 51 and handle 52, and described cover cranse 51 is plugged on handle cam by connector; Button holds together handle 52, and cam height point props up cover cranse 51 can tightening sleeve cranse 51, pulls open handle, and cam low spot leaves cover cranse 51 can loosen cover cranse 51.
