Abstract
The utility model relates to a high-voltage metering box current porcelain insulator structure, comprising a porcelain insulator, a through threaded stud, a wire inlet conducting plate arranged on the upper part of the porcelain insulator and a wire outlet connector arranged on the upper end of the stud. The wire outlet connector is mutually insulated with the wire inlet conducting plate through a ceramic isolating ring, the upper end of a conducting wire leading to the input end of a current mutual inductor is connected with the wire inlet conducting plate, and the lower end of the conducting wire is threaded out through an opening on an insulating press plate at the bottom of the porcelain insulator. The utility model is characterized in that the upper part of the porcelain insulator is provided with or has a ceramic support ring seat, and the wire inlet conducting plate having a middle part with a through hole is arranged on the ceramic support ring seat. The utility model has the advantages of simple structure and low cost.
Description
The utility model relates to a kind of high pressure measurement tank current porcelain vase structure.
Existing high pressure measurement tank current porcelain vase structure as shown in Figure 1, it comprises the insulating press boards 7 of being located at the porcelain vase bottom, run through stud 1, be located at the outlet connector that runs through the stud upper end, be sheathed on the inlet wire connector on porcelain vase top, and be located at the ceramic shading ring 2 between outlet connector and the inlet wire connector.The inlet wire connector is by the big copper lid 3 of the annular that is buckled on the porcelain vase upper lateral part, is positioned at the inlet wire conductive plate 4 of the big copper side of covering and places Da Tonggai and inlet wire conductive plate middle part through hole and be enclosed within copper sheathing 5 compositions of bolt periphery.Pass with the joining opening 8 of conductor wire 6 on porcelain vase bottom insulation pressing plate 7 that leads to the current transformer input of copper sheathing downside.The outlet connector constitutes in order to two nuts 12 that connect outlet conductor wire 18 by being buckled on the little annular copper lid 10 on the ceramic shading ring and being spun on the bolt upper end.The bolt lower end has the nut 13 of a locking insulating press boards, and the conductor wire 14 that leads to the current transformer output is connected on the bolt lower end.The major defect that this porcelain vase structure exists is that parts are more, and owing to the big lid of the annular in little ring cover in the outlet connector and the inlet wire connector becomes by copper, so production cost is higher.
The purpose of this utility model is that a kind of high pressure measurement tank current porcelain vase structure will be provided, and its cost is lower.
The utility model is to constitute like this, it comprises porcelain vase, run through stud, be located at the internal wiring plate and the power line connector of being located at the through bolt upper end on porcelain vase top, between power line connector and the internal wiring plate through ceramic shading ring mutually insulated, the internal wiring upper end that leads to current transformer links with the internal wiring plate, and the opening of lower end on porcelain vase bottom insulation pressing plate passes.It is characterized in that: (1) porcelain vase top is provided with or has a ceramic support ring seat; (2) the internal wiring plate that has through hole in the middle part of places on the ceramic support ring seat.
The utility model is because employing ceramic support ring seat has replaced the big copper lid of the annular that is buckled on porcelain vase top, so cost is lower.In addition, when ceramic support ring seat and porcelain vase were fired into one, structure of the present utility model was then simpler.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is former high pressure measurement tank current porcelain vase structure construction figure.
Fig. 2 is the utility model structural map.
With reference to Fig. 2, the utility model comprises porcelain vase, run through stud, be located at the inlet wire conductive plate and the outlet connector of being located at the bolt upper end on porcelain vase top, between outlet connector and the inlet wire conductive plate through ceramic shading ring 2 mutually insulateds, the conductor wire upper end that leads to the current transformer input links with the inlet wire conductive plate, and the opening of lower end on porcelain vase bottom insulation pressing plate passes, and it is characterized in that: (1) porcelain vase top is provided with or has a ceramic support ring seat 15; (2) the inlet wire conductive plate 17 that has through hole in the middle part of places on the ceramic support ring seat.
Above-mentioned outlet connector constitutes in order to two nuts 12 that connect outlet conductor wire 18 by being buckled on the little ceramic cap 16 on the ceramic shading ring and being spun on the bolt upper end.
Than existing high pressure measurement tank current porcelain vase structure, embodiment of the present utility model is simple structure not only, is convenient to assembling, saves copper material, and help outlet conductor wire mutually insulated on inlet wire conductive plate and the little ceramic cap, thereby prevent the power stealing of electricity filching person overlap joint.
