Description
Technical field
The present invention relates to a kind of security tool, a kind of charged low-voltage conductor cut-offs security tool specifically, belongs to electrical equipment technical field.
Background technology
In recent years; the in-depth of building along with new round electric network reconstruction and digitlization, intelligent power network advances; the comprehensive automation transformation project of power system is on the increase, and often have a large amount of protection screen cabinets to need to carry out replacing transformation every year, the little bus in screen top cut-offs cross-over connection operation and also gets more and more.Each little bus in protection screen top mostly adopts solid exposed copper rod, causes staff to work on the protection screen top run, and the person easily occurs and gets an electric shock and false protection accident, there is serious potential safety hazard.
Cut-off for the little bus in screen top in prior art, all need to increase insulation board, flow process operation is long, longevity of service, needs personnel many, and in work, dangerous spot is more, and security is low.Because little bus is laid in protection screen top, more than 2 meters, need cat ladder, and working space is narrow and small apart from ground during operation, terminal screw is all positioned at and runs little bus lower end, adds the work difficulty of cut-offfing little bus.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of charged low-voltage conductor to cut-off security tool, improve the security that the little bus in screen top cut-offs work operations, the danger source point in effective management and control work progress, increase security, improve operating efficiency.
According to technical scheme provided by the invention, charged low-voltage conductor is cut-off security tool and is comprised electric jig saw, it is characterized in that: electric jig saw front end fixed connecting plate, fixed connector on connecting plate; The output shaft front end of electric jig saw is connected back link through connecting plate with connector, and back link front end connects front rod; Insulated connecting rod is provided with between back link and front rod; Front rod front end connects cutter head by lock sleeve, and is locked by locking nut; Connector is connected by screw insulating sleeve, and insulating sleeve by back link, insulated connecting rod and front rod cover therein; Insulating sleeve front end connects insulating sheath, and cutter head is positioned at insulating sheath.
Further, handle that insulating sleeve is slidably installed connects, and handle adapter sleeve lower end is bolted handle.
Further, insulating sheath comprises upper insulation plate and is positioned at the lower insulation plate below upper insulation plate.
Further, lower insulation plate front center is provided with the edge of a knife.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, easy to carry, and two people can easily complete the work of cut-offfing little bus, applied widely; Improve the security that the little bus in screen top cut-offs work operations, the danger source point in effective management and control work progress, increases security; Shorten flow process operation, reduce a staff needs, improves operating efficiency simultaneously.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises electric jig saw 1, electric jig saw 1 front end fixed connecting plate 10, fixed connector 11 on connecting plate 10.Output shaft 2 front end of electric jig saw 1 is connected back link 12 through connecting plate 10 with connector 11, and back link 12 front end connects front rod 14.Insulated connecting rod 13 is provided with between described back link 12 and front rod 14.Front rod 14 front end connects cutter head 16 by lock sleeve 15, and is locked by locking nut.
Connector 11 is connected by screw insulating sleeve 3, back link 12, insulated connecting rod 13 and front rod 14 overlap therein by insulating sleeve 3.Insulating sleeve 3 front end connects insulating sheath 6, the lower insulation plate 8 that insulating sheath 6 comprises upper insulation plate 7 and is positioned at below upper insulation plate 7, and as shown in Figure 3, lower insulation plate 8 front center is provided with the edge of a knife 9.Cutter head 16 is positioned at insulating sheath 6, and between the lower insulation plate 8 below upper insulation plate 7, the cutter head 16 seesawed can move forward and backward in the edge of a knife 9.
Handle that described insulating sleeve 3 is slidably installed connects 4, and handle adapter sleeve 4 lower end is bolted handle 5, is operated, work more stable by the more convenient staff's both hands of handle 5; Meanwhile, handle adapter sleeve 4 can move forward and backward adjustment position on insulating sleeve 3.
Operation principle of the present invention is: the safety of cut-offfing cross-over connection operation in order to improve the little bus in screen top, is provided with insulated connecting rod 13, thus makes front and back structural insulation between back link 12 and front rod 14.Back link 12 and front rod 14 outer ring are provided with insulating sleeve 3, insulate further to device, the security of protection inner link mechanism.Cutter head 16 has the lower insulation plate 8 below upper insulation plate 7, prevent cutter head 16 because maloperation damages the copper rod near operation bus, further increase security.Structure of the present invention is simple, compact, reasonable, easy to carry, and two people can easily complete the work of cut-offfing little bus, applied widely; Improve the security that the little bus in screen top cut-offs work operations, the danger source point in effective management and control work progress, increases security; Shorten flow process operation, reduce a staff needs, improves operating efficiency simultaneously.
