Abstract
A combined instrument transformer comprises a voltage transformer and a current transformer, and is characterized in that a flute with a downward opening is arranged at the bottom of the casting body of the dingle-phase voltage and current transformers. A secondary connection terminal at the bottom of the casting body is positioned in the flute and is connected with a leading out cable. A silicon rubber for fixedly sealing the secondary terminal and cable is cast in the flute, and the transformers are assembled on a base. The utility model combines the independent transformers, and the whole secondary connection terminal is fixedly sealed in the flute at the bottom of the casting body, so that the electric larceny prevention, water proof and pollution prevention can be effectively realized, the disassembly and replacement of the unit set are made convenient and the capital is saved. With relatively small volume, the combined structure is convenient for installation.
Description
Technical field the utility model relates to a kind of electric component, particularly a kind of combined instrument transformer of outdoor metering usefulness.
The combination transformer that background technology is used at present is that electric current, voltage transformer are integral with poured with epoxy resin during fabrication.The problem that exists is that volume is big, and Heavy Weight is installed inconveniently, in use breaks down if any a single-phase transformers, can not remove separately, and need all to change, and wastes very greatly, does not have anti-stealing electricity function.
The summary of the invention the purpose of this utility model is to provide a kind of installation, use, replacing convenient, flexible, and is reliable and have a metering combined instrument transformer of anti-stealing electricity function.
Technical solution of the present utility model is: the single-phase voltage of absolute construction, current transformer, the bottom of its pour mass has downward opening groove, the secondary connection terminal that is arranged on the pour mass bottom is positioned at groove, and be connected with outgoing cable, be cast with the silicon rubber that is used for secondary terminal and the solid envelope of cable usefulness in the groove, instrument transformer is assembled on the base.
Described metering combined instrument transformer is made up of the monophase current instrument transformer of single-phase potential transformer that is arranged side by side two platform independent structures on base and two platform independent structures.
Described current transformer, its binding post is arranged on both sides, pour mass top.
The utility model has adopted the single-phase transformers with absolute construction to fit together, and its secondary connection terminal integral body is sealed in the groove of pour mass bottom admittedly, so not only can anti-electricity-theft effectively, waterproof, anti-pollution, and be convenient to the separate unit dismounting and change, the saving fund.Fabricated structure is convenient to install, and volume is less.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of the single-phase metered voltage instrument transformer 1 of two platform independent structures and the single-phase metering current mulual inductor 2 of two platform independent structures, the bottom of each instrument transformer all is provided with downward opening groove 3, the groove that is installed in 4 instrument transformers on the base 4 side by side connects, the secondary connection terminal that is located at instrument transformer pour mass bottom is positioned at groove, the secondary connection terminal is connected the back its integral body is sealed admittedly with silicon rubber with outgoing cable 6.The structure of each instrument transformer is by the instructions for use design.The primary connection terminal 5 of current transformer is positioned at both sides, pour mass top, is convenient to wiring, and can prevent that the short-circuit of terminals from causing metering inaccurate.
Claims (3)
1, a kind of metering combined instrument transformer, comprise the voltage transformer summation current transformer, the single-phase voltage, the current transformer that it is characterized in that absolute construction, the bottom of its pour mass has downward opening groove, the secondary connection terminal that is arranged on the pour mass bottom is positioned at groove, and be connected with outgoing cable, being cast with in the groove and being used for secondary terminal and cable silicon rubber with solid envelope, instrument transformer is assembled on the base.
