Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the application's protection.

Embodiment one

Fig. 1 is the structural drawing of the disclosed a kind of current measuring device of the embodiment of the present application.

Current measuring device as shown in Figure 1 comprises clamp on amperemeter 10, telescopic insulation handle 20, shaft coupling 23, backguy 30 and handle 40.Clamp on amperemeter 10 is hinged by shaft coupling 23 with the upper end 21 of insulating bar 20, and the fastener 113 for opening binding clip 11 of clamp on amperemeter 10 is connected by backguy 30 with handle 40.

Clamp on amperemeter 10 comprises binding clip 11, and binding clip comprises fixedly bayonet socket 111 and movable bayonet 112, and when movable bayonet 112 moved, binding clip 11 will open, and the binding clip 11 that will open this moment blocks wire to be measured, and then closed binding clip 11 just can be measured.Be provided with the fastener 113 of mobile movable bayonet 112 to open binding clip 11 on the movable bayonet 112.

Insulation handle 20 is for hollow structure and be socketed with extension rod, pulls out the length that extension rod just can prolong long insulating handle 20, can measure the electric current of the high-altitude power equipment of differing heights; When carrying, extension rod can be received in the insulation handle 20 convenient transportation.

The upper end end 21 of insulation handle 20 is hinged by shaft coupling 23 with the table body of clamp on amperemeter 10.Shaft coupling 23 also is the cross universal shaft coupling, can make clamp on amperemeter 10 become any angle with the axis of insulation handle 20.Before measurement, according to the wire of power equipment to be measured move towards to regulate angle between clamp on amperemeter 10 and the insulation handle 20 so that more convenient during measurement.

One end of handle 40 is connected on the lower end 22 of insulation handle 20 by rotating shaft, and backguy 30 head ends are fixed on clamp on amperemeter 10 fasteners 113, and the tail end of backguy 30 is connected to the other end or the middle part of handle 40.

When measuring, utilize insulation handle 20 with the jaw 11 close wires to be measured of clamp on amperemeter 10, pull handle 40 downwards, handle 40 drives backguy 30, and backguy 30 pulls down moved fastener 113, fastener 113 drives movable bayonet 112, binding clip 11 opens, and blocks wire to be measured with the binding clip 11 that opens, and then decontrols handle 40, binding clip 11 is closed under the effect of self spring, then measures; After measurement is finished, pull handle 40 downwards, pulling backguy 30 band moved fasteners 113 open binding clip 11 again, just binding clip 11 can be left wire to be measured, finish surveying work.

Can find out from above-mentioned technical scheme, the disclosed current measuring device of the application can utilize insulating bar 20 that clamp on amperemeter 11 is measured near the high-altitude power equipment, no longer need survey crew to measure convenient during operation, safety near the high-altitude power equipment.

Embodiment two

Fig. 2 is the structural drawing of the disclosed another kind of current measuring device of the embodiment of the present application.

In embodiment one, be to utilize backguy 30 direct pull fasteners 113, finish the action of opening binding clip 11 with mobile movable bayonet 112.In the present embodiment, increase a pressing plate 50, utilized pressing plate 50 to promote fastener 113 to open binding clip 11.

As shown in Figure 2, an end that is provided with the first support 31, the first supports 31 at the caliper of clamp on amperemeter 10 is fixedly connected with the table body of clamp on amperemeter 10, and the other end is provided with pressing plate 50, and the stiff end 51 of pressing plate 50 is connected by rotating shaft with the first support 31.The first support 31 can also be arranged on the insulation handle 20.

The shape of pressing plate 50 is preferably semilune, and the arc-shaped side 53 of pressing plate contacts with fastener 113, and free end 51 is connected with the head end of backguy 30, and the tail end of backguy 30 is connected on the handle 40.During pulling handle 40, handle 40 drives backguy 30, backguy 30 pulling pressing

plates

50, and 53 pairs of fasteners 113 of the arc-shaped side of pressing plate 50 are exerted pressure, and fastener 113 drives movable bayonet 112 and moves under the effect of pressing plate 50, finish the action of opening binding clip 11.

When adopting the clamp on amperemeter 10 of certain model, the fastener 113 that being used for of this model clamp on amperemeter 10 opened binding clip 11 is very little with the angle of hinged insulation handle 20, at this time binding clip 11 might can not be opened with backguy 30 direct pull fasteners 113, and the pressing plate 50 that the present embodiment increases can be exerted pressure to fastener 113, has avoided can't opening the mode of the clamp on amperemeter 10 usefulness direct pull fasteners 113 of certain model the problem of binding clip 11.

Embodiment three

In embodiment two, when the angle of clamp on amperemeter 10 and insulation handle 20 during in some angle, pulling pressing plate 50 may make pressing plate 50 away from the fastener 113 of clamp on amperemeter 10, so that pressing plate 50 can not exert pressure to open binding clip 11 to fastener 113, at this time need repeatedly to adjust the angle of clamp on amperemeter 10 and insulation handle 20, use comparatively inconvenience.For addressing this problem, set up a pilot hole 321 on the basis of embodiment two.

Current measuring device as shown in Figure 3, fixedly bayonet socket 111 1 sides near binding clip 11 on the table body of clamp on amperemeter 10 are provided with the second support 32, one end of the second support 32 is fixedly connected with the table body of clamp on amperemeter 10, the other end is provided with pilot hole 321, pilot hole 321 can be arranged on the hole on the second support 32 other ends, also can be arranged on the ring on the second support other end.The second support 32 can also be arranged on the insulation handle 20.

The head end of backguy 30 connects the free end 51 of pressing plate 50, then passes pilot hole 321, is connected with handle 40 at last.So no matter clamp on amperemeter 10 is in any angle with insulation handle 20, and backguy 30 all pulls to fastener 113 with pressing plate 50 under the effect of pilot hole 321, to finish the action of opening binding clip 11.
