Namely the utility model designs on this basis.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of 10kV single-phase small galvanic current instrument transformer, its structure is simple, novel in design, there is between primary connection terminal and secondary wiring terminals better safe creep distance, and to secondary wiring terminals, there is further safety protection function.
To achieve these goals, the technical solution of the utility model: a kind of 10kV single-phase small galvanic current instrument transformer, it comprises and has primary connection terminal respectively, the instrument transformer body of secondary wiring terminals, described primary connection terminal is on the top of described instrument transformer body, described secondary wiring terminals is on described instrument transformer body lower part one end, described instrument transformer body upper part two ends are symmetrical set, and often end has the vertical portion on top and the rake of bottom, described secondary wiring terminals is positioned on the instrument transformer body below described rake, be horizontally disposed with between described vertical portion and rake protrude from this vertical portion and by this vertical portion, the protruding eave portion that rake is connected in one.
Further, described protruding eave portion and described secondary wiring terminals are in described instrument transformer body with on one end.
Further, the cross section of described protruding eave portion is circular arc.
Further, the vertical plane of described rake and described instrument transformer body end is 56 ° ~ 78 ° angles.
Further, described protruding eave portion and described vertical portion, rake one form.
Further, described secondary wiring terminals has anti-electricity-theft structure.
The beneficial effects of the utility model: by the setting of protruding eave portion, add on the one hand the safe creep distance between primary connection terminal on instrument transformer body and secondary wiring terminals, on the other hand, this protruding eave portion serves certain protective action to secondary wiring terminals.So the utility model structure is simple, novel in design, there is between primary connection terminal and secondary wiring terminals better safe creep distance, and to secondary wiring terminals, there is further safety protection function.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation sketch of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of as Fig. 1, 10kV single-phase small galvanic current instrument transformer described in Fig. 2, it comprises and has primary connection terminal 14 respectively, the instrument transformer body 1 of secondary wiring terminals 10, described primary connection terminal 14 is on the top of described instrument transformer body 1, described secondary wiring terminals 10 is on described instrument transformer body 1 lower end thereof, described instrument transformer body 1 both upper ends thereof is symmetrical set, and often end has the vertical portion 12 on top and the rake 11 of bottom, described secondary wiring terminals 10 is positioned on the instrument transformer body 1 below described rake 11, be horizontally disposed with between described vertical portion 12 and rake 11 protrude from this vertical portion 12 and by this vertical portion 12, the protruding eave portion 13 that rake 11 is connected in one.
The utility model carries out Curve guide impeller on the basis of original current transformer, by the setting of protruding eave portion 13, add on the one hand the safe creep distance between primary connection terminal 14 on instrument transformer body 1 and secondary wiring terminals 10, on the other hand, this protruding eave portion 13 pairs of secondary wiring terminals 10 serve certain protective action.
For protruding eave portion 13, it can be arranged at the two ends of instrument transformer body 1, to form symmetrical structure, and convenient perfusion, and improve the appearance looks elegant degree of product; Also can be arranged at one end, namely shown in the present embodiment legend, protruding eave portion 13 and described secondary wiring terminals 10 are in described instrument transformer body 1 with on one end, to save unsaturated-resin material.In this example, the cross section of protruding eave portion 13 is arranged in circular arc, namely ensure that the round and smooth degree of whole current transformer product appearance, certainly, in practice, the cross section of this protruding eave portion 13 can also be other fusiform structure, such as square, rectangle, trapezoidal etc.
