Description
Technical field
The utility model belongs to power distribution protection technical field, relates in particular to a kind of transformer grounding protective device.
Background technology
Earth connection is to carry out ground connection use for unexpectedly there is voltage on the equipment having had a power failure and circuit time, to ensure staff's personal safety, is widely used in power domain.In actual use, often different equipment need to configure the earth connection of different size, in maintenance and repair, need to carry different earth connections and adapt to different user demands, comparatively loaded down with trivial details.At present, the portable earth connection that domestic transformer uses, has according to the classification of joint form: single tongue formula, double tongue type, the type such as spiral presses formula, holds flat, hedgehog hydnum formula.Wherein single tongue formula, double tongue type is mainly used in circuit or bus and has a power failure and use while doing safety measure; Spiral presses formula, holds flat, is mainly used in when safety measure is done in busbar power failure and uses.
Due to the difference of grounding wire connector form, in actual applications, the earth connection of hanging wire road and bus can not be applied in bus-bar earthing easily, same, and earth connection used when bus-bar earthing can not conveniently be applied to the ground connection of circuit and bus.So just cause earth connection deficiency and the remaining strange phenomenon of earth connection in actual production.As not enough in the ground wire of hanging earthing conductor bus, and the earth connection that extension busbar is used is not used, on the contrary there is same situation.If be equipped with the enough various forms of earth connections of quantity, need to increase the input of fund, cause when increasing cost and increased again maintenance, also caused the idle and waste of ample resources simultaneously.
Utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of easy and simple to handle, can be used for the transformer grounding protective device that bus-bar earthing can be used for again busbar grounding.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: transformer grounding protective device, comprise screw rod, top board, lower platen, wire, warning mark and ground connection cuttage, screw rod vertically arranges, top board and lower platen are all horizontally disposed with, lower platen is positioned at top board below, the coaxial T shape locating shaft that is fixedly connected with in screw rod upper end, top board one end is rotatably connected on T shape locating shaft, lower platen is threaded on screw rod, the coaxial insulated handle that is fixedly connected with in screw rod lower end, top board lower surface and top board upper surface respectively upper and lower correspondence are provided with the pressuring line groove of an arc, top board lower surface is connected with the opening bullet tongue that is positioned at pressuring line groove outside, between opening bullet tongue and top board, be provided with the spring for the opening bullet tongue that resets, lower platen upper surface is provided with and stops the outward-dipping semi-cylindrical hill of opening bullet tongue, ground connection cuttage top is provided with binding clip, lower platen is provided with threaded connection hole, wire upper end is crimped in threaded connection hole by connecting bolt, wire lower end is connected with binding clip, warning mark is located at ground connection cuttage sidepiece.
Described ground connection cuttage lower end is provided with three taper fixed teeth side by side, and three taper fixed teeth are upper coarse and lower fine structure, and a middle taper fixed teeth length is greater than another two taper fixed teeth.
On described screw rod, be threaded and be positioned at lower platen below for compressing the clamp nut of lower platen.
Adopt technique scheme, two pressuring line grooves between top board and lower platen are for connecting circular bus, and the planar section between top board and lower platen is used for connecting busbar; The structure of opening bullet tongue is identical with key chain opening-closing structure, not only for limiting the position of bus or busbar, and the effect of enhancing conductive contact area; In the time that bus or busbar are carried out to crimping, only need hand-held insulated handle to rotate, insulated handle drive screw and T shape locating shaft rotate, because top board and T shape locating shaft are rotationally connected, top board is motionless, because lower platen is connected with screw flight, lower platen moves upward along screw rod, so just the bus between top board and lower platen or busbar are compressed, and then use spanner by clamp nut and press lower platen, so just can avoid lower platen automatically to unclamp under the external environment conditions such as vibration.Taper fixed teeth is pricked underground, and middle taper fixed teeth is pricked deeply, and two taper fixed teeth of both sides are pricked to such an extent that shallowly play the anti-deflected effect of supporting.Warning mark plays warning people, and this is ground wire, No nearing.
The utility model utility model is simple in structure, easy to make, crimping is firm, has improved operating efficiency, the utility model can meet the requirement of hanging busbar, can meet again the grounding requirement of hanging bus and wire, transformer can connect with the general earth connection of slip-off preventing, has good versatility, thereby kind and the quantity of stock's earth connection are reduced, avoided the idle and waste of resource, in electric power enterprise and large-scale power user, can obtain extensively generally applying, market value is considerable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, transformer grounding protective device of the present utility model, comprise screw rod 1, top board 2, lower platen 3, wire 4, warning mark 5 and ground connection cuttage 6, screw rod 1 vertically arranges, top board 2 and lower platen 3 are all horizontally disposed with, lower platen 3 is positioned at top board 2 belows, the coaxial T shape locating shaft 7 that is fixedly connected with in screw rod 1 upper end, top board 2 one end are rotatably connected on T shape locating shaft 7, lower platen 3 is threaded on screw rod 1, the coaxial insulated handle 8 that is fixedly connected with in screw rod 1 lower end, top board 2 lower surfaces and top board 2 upper surfaces respectively upper and lower correspondence are provided with the pressuring line groove 9 of an arc, top board 2 lower surfaces are connected with the opening bullet tongue 10 that is positioned at pressuring line groove 9 outsides, between opening bullet tongue 10 and top board 2, be provided with the spring 11 for the opening bullet tongue 10 that resets, lower platen 3 upper surfaces are provided with the semi-cylindrical hill 12 that stops that opening bullet tongue 10 is outward-dipping, ground connection cuttage 6 tops are provided with binding clip 13, lower platen 3 is provided with threaded connection hole, wire 4 upper ends are crimped in threaded connection hole by connecting bolt 14, wire 4 lower ends are connected with binding clip 13, warning mark 5 is located at ground connection cuttage 6 sidepieces.
