Abstract
The utility model discloses a tapping jointing clamp for measuring resistance and voltage ratio of a transformer, which comprises a U-shaped clamp and a clamping element, wherein the U-shaped clamp comprises tapping conductors and a connection hose; the tapping conductors are respectively connected to both ends of the connection hose. The tapping jointing clamp has the advantages that the structure is simple and the use is convenient; only the two tapping conductors need to be respectively connected with tapping leads, and the two tapping conductors are clamped by the clamping element, and the measurement work can be carried out by connecting the two tapping leads; the original steps of disassembling a bolt and mounting a lug plate are not needed, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of tap binding clip that is used for measuring transformer resistance and voltage ratio.
Background technology
When the direct current resistance of measurement dry-type transformer and voltage ratio, transformer of every survey, the working time major part is used in replacing with of branch contact pin.The structural representation of lug plate in the synoptic diagram of lug plate user mode as shown in Figure 1 and the accompanying drawing 1 shown in the accompanying drawing 2, dry-type transformer is generally non-excitation pressure adjustment, and lug plate 7 overlap joints are passed through in the connection of each tap lead 6, realizes with bolted again.The resistance and the voltage ratio of a tap lead of every survey all need dismounting, screw bolt and change branch contact pin, and work efficiency is very low.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of tap binding clip that is used for measuring transformer resistance and voltage ratio simple in structure, easy to use.
Technical scheme: a kind of tap binding clip that is used for measuring transformer resistance and voltage ratio, comprise U type folder and clamping element, described U type folder comprises the tap lead and is connected flexible pipe that described tap lead is connected to described connection flexible pipe two ends.
Described tap lead is a copper coin, can engage conducting with tap lead easily.
Described clamping element is electrician folder, clamps two tap leads and makes its conducting, and is easy to operate, and electrician's folder is general part, takes easily.
Described connection flexible pipe also is enclosed with insulation sleeve outward, and is convenient hand-held.
Beneficial effect: compared with prior art, the utility model has the advantages that simple in structure, the use aspect, only two tap leads need be connected tap lead respectively, and use the clamping element clamping, connect two tap leads and can carry out surveying work, saved the step of the lug plate of demounting bolt installation originally, improved work efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Shown in accompanying drawing 3-5, a kind of tap binding clip that is used for measuring transformer resistance and voltage ratio comprises U type folder 1 and clamping element 2, and described U type folder 1 comprises tap lead 3 and be connected flexible pipe 4 that described tap lead 3 is connected to described connection flexible pipe 4 two ends.
When using the utility model tap binding clip measuring transformer resistance and voltage ratio, the U type is pressed from both sides the tap lead of being made by copper coin at 1 two ends 3 to be connected on two tap leads 6, clamp two tap leads 3 with electrician's folder as clamping element 2 then, make its contact conducting, can carry out normal surveying work.After measurement finishes, unclamp clamping element 2, take off U type folder 1 and can change to other measurement point and measure.
