Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide that a kind of installation dimension is little, production cost is low, Maintenance free and change fast and easily the bushing shell for transformer with intelligent measure terminal.
Bushing shell for transformer with intelligent measure terminal of the present utility model, comprise casing flange, guide rod and capacitor core, the outermost pole plate of described capacitor core is earthing, the described bushing shell for transformer with intelligent measure terminal also comprises intelligent measure mechanism, described intelligent measure mechanism comprises electric capacity and intelligent measure terminal, described intelligent measure terminal is electrically connected to by wire with one end of electric capacity, the other end of electric capacity is electrically connected to by wire with earthing, and one end being connected with intelligent measure terminal of described electric capacity is also electrically connected to guide rod.
Further, with bushing shell for transformer described in the bushing shell for transformer of intelligent measure terminal, also comprise mounting groove, described mounting groove is positioned at casing flange inside, in mounting groove, be provided with the first cable-through hole and the second cable-through hole, the electric capacity of described intelligent measure mechanism is arranged in mounting groove, the wire being electrically connected to earthing is electrically connected to one end of electric capacity by the first cable-through hole, and the wire being electrically connected to intelligent measure terminal is electrically connected to the other end of electric capacity by the second cable-through hole.
Further, with bushing shell for transformer described in the bushing shell for transformer of intelligent measure terminal, the length of described mounting groove is 60 millimeters, and wide is 50 millimeters, is 13 millimeters deeply.
Further, with bushing shell for transformer described in the bushing shell for transformer of intelligent measure terminal, the diameter of described the first cable-through hole and the second cable-through hole is 7 millimeters.
By such scheme, the utility model at least has the following advantages: the bushing shell for transformer with intelligent measure terminal of the present utility model, and adopt small capacitor to get measuring-signal, size is little, and cost is low, and disposable use does not need to safeguard, changes convenient and swift.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the front view of the bushing shell for transformer with intelligent measure terminal of the present utility model;
Fig. 2 is the front view of the flange of the bushing shell for transformer with intelligent measure terminal of the present utility model;
Fig. 3 is that cutaway view is looked on a left side of Fig. 2.
In figure: 1: casing flange; 2: guide rod; 3: mounting groove; 4: the first cable-through holes; 5: the second cable-through holes.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Referring to shown in Fig. 1 to Fig. 3, bushing shell for transformer with intelligent measure terminal of the present utility model, comprise casing flange 1, guide rod 2 and capacitor core, the outermost pole plate of capacitor core is earthing, bushing shell for transformer with intelligent measure terminal also comprises intelligent measure mechanism, intelligent measure mechanism comprises electric capacity and intelligent measure terminal, intelligent measure terminal is electrically connected to by wire with one end of electric capacity, the other end of electric capacity is electrically connected to by wire with earthing, and one end being connected with intelligent measure terminal of electric capacity is also electrically connected to guide rod.Bushing shell for transformer bushing shell for transformer with intelligent measure terminal also comprises mounting groove 3, mounting groove is positioned at casing flange inside, in mounting groove, be provided with the first cable-through hole 4 and the second cable-through hole 5, the electric capacity of intelligent measure mechanism is arranged in mounting groove, the wire being electrically connected to earthing is electrically connected to one end of electric capacity by the first cable-through hole, and the wire being electrically connected to intelligent measure terminal is electrically connected to the other end of electric capacity by the second cable-through hole.
During concrete measurement, the measuring junction of measurement mechanism can be connected with intelligent measure terminal, due to the electric capacity between intelligent measure terminal and earthing, its capacitance is less, and larger with the body capacitance of the bushing shell for transformer bushing shell for transformer of intelligent measure terminal, therefore, the magnitude of voltage of drawing from Intelligent terminal is less, can obtain the magnitude of voltage of conducting rod by voltage divider principle, simultaneously due to electric capacity small volume, thereby realized that installation dimension is little, production cost is low, Maintenance free and change object fast and easily.
As preferably, with the bushing shell for transformer bushing shell for transformer of intelligent measure terminal, also comprise mounting groove, the length of mounting groove is 60 millimeters, wide is 50 millimeters, is 13 millimeters deeply.
As preferably, with bushing shell for transformer described in the bushing shell for transformer of intelligent measure terminal, the diameter of the first cable-through hole and the second cable-through hole is 7 millimeters.
Below be only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
