Abstract
The invention relates to a measuring trolley and belongs to the technical field of power distribution devices. The measuring trolley comprises a frame chassis, a frame, a current transformer, a voltage transformer, a contact arm and a fuse protector, wherein the frame is arranged on the frame chassis; the current transformer is arranged on the frame; and the voltage transformer is arranged on the frame chassis. The measuring trolley is characterized in that: the contact arm is arranged on the current transformer through an upper copper bar; one end of the fuse protector is connected with the voltage transformer and the other end of the fuse protector is connected with a lower copper bar; and the lower copper bar is connected with the upper copper bar. The measuring trolley has the advantages that: the upper copper bar is arranged on the current transformer and the contact arm is directly arranged on the upper copper bar, so the appearance volume is reduced, the processing precision is reduced and the strength requirement of the measuring trolley is completely met; and the fuse protector is arranged on the voltage transformer and is connected with the upper copper bar through the lower copper bar. Due to the adoption of the assembling structure, the electrical clearance requirement is met, the insulating cover and the vulcanized small copper rod in the prior art are canceled, the assembling steps are simplified and the using cost is reduced.
Description
Technical field
The invention belongs to power distribution device technique field, be specifically related to a kind of supporting be the metering dolly on the 10kV armored withdraw type ac metal closing switch gear in rated voltage, be used for measurement and record to electric energy
Background technology
Metering dolly on
existing 10kV armored withdraw type ac metal closing switch gear; Its structure is disclosed by Fig. 2; It comprises frame chassis 1, be located at vehicle frame 2 on the frame chassis 1, be installed in current transformer 3 on the vehicle frame 2, be installed in voltage transformer 4, contact arm 5 and fuse 6 on the frame chassis 1; Described contact arm 5 is installed on the current transformer 3 through U type bracing frame 9; One end of described fuse 6 is connected with voltage transformer 4, and the other end of fuse 6 is connected with current transformer 3.In said apparatus; In order to make the electric clearance between bracing frame 9 and the cabinet can satisfy the standardization requirement; Usually need install first insulating cover 91 in the outside of bracing frame 9 additional; According to the requirement of city electric company, the electric energy that voltage transformer 4 is consumed in the metering dolly must be in measures range, in order to satisfy this requirement simultaneously; An end of fuse 6 can only adopt the little copper rod through vulcanizing treatment to be connected with voltage transformer 4 when mounted, outside fuse 6 and little copper rod, installs second insulating cover 61 simultaneously additional.The deficiency that this metering dolly exists is: not only volume is big, and parts are many, complex structure, and use cost is high, and also for fear of the error that in installation process, possibly occur, higher to the requirement on machining accuracy of each parts, improved use cost equally.
In view of above-mentioned prior art, be necessary the mounting structure of existing metering dolly is improved, the technical scheme that will introduce below produces under this background
Summary of the invention
the object of the present invention is to provide that a kind of volume is little, cost is low, when satisfying electric clearance and requirement of strength, can reduce number of components and parts, simplify the metering dolly of installation steps.
the objective of the invention is to realize like this; A kind of metering dolly; Comprise frame chassis, be located at vehicle frame on the frame chassis, be installed in current transformer on the vehicle frame, be installed in voltage transformer, contact arm and fuse on the frame chassis; Be characterized in: described contact arm is installed on the current transformer through copper bar on; One end of described fuse is connected with voltage transformer, and the other end of fuse is connected with copper bar once, described copper bar down with described on copper bar be connected.
In a concrete embodiment of the present invention, described copper bar down is connected through securing member with described going up between the copper bar
.
in another concrete embodiment of the present invention, described securing member is meant screw or rivet etc.
the present invention is because after adopting said structure; The beneficial effect that has: copper bar on is being installed on the current transformer; Contact arm directly is installed on last copper bar, is compared with the bracing frame in the prior art, not only overall volume dwindles; And having reduced machining accuracy, intensity meets the required requirement of strength of metering dolly fully simultaneously; Fuse is installed on voltage transformer, and described fuse is connected this mounting structure through copper bar once with last copper bar; Both satisfied the electric clearance requirement; Cancel the insulating cover in the prior art again, vulcanized little copper rod, simplified installation steps, reduced use cost.
