Abstract
The utility model relates to the field of mutual inductors, and discloses a combination type mutual inductor. The combination type mutual inductor comprises an installation base, wherein at least two single-phase voltage mutual inductors and at least two single-phase current mutual inductors are arranged on the installation base, each single-phase current mutual inductor is arranged between every two adjacent single-phase voltage mutual inductors, and the single-phase voltage mutual inductors, the single-phase current mutual inductors and the installation base are integrally arranged through epoxy resin in a pouring mode. The combination type mutual inductor is compact in structure, and due to the fact that the current mutual inductors and the voltage mutual inductors are combined together, installation cost and maintenance cost of equipment are reduced, an occupied space is reduced, labor intensity of workers is reduced, and practicability and promotional value are quite high.
Description
Technical field
The utility model relates to the instrument transformer field, has related in particular to a kind of combined instrument transformer.
Background technology
The electric energy metrical cabinet is a kind of for the equipment that carries out electric energy metrical between electric company and the user, by making Current Transformer, voltage measuring transformer electric current, voltage, in existing electric energy metrical cabinet, adopt current transformer and voltage transformer independently to use mostly, be connected with electrical network respectively and measure, this can cause metering cabinet internal wiring terminal number amount more, and it is big to take up room, the installation and maintenance inconvenience.
Summary of the invention
The utility model provides a kind of compact conformation at the deficiencies in the prior art, and current transformer and voltage transformer are effectively combined, and has reduced the cost of equipment, reduces the combined instrument transformer of space hold.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Combined instrument transformer, comprise mounting seat, mounting seat is provided with at least two single-phase potential transformers and at least two monophase current instrument transformers, described monophase current instrument transformer is arranged between adjacent two single-phase potential transformers, being filled with dielectric between described single-phase potential transformer, the monophase current instrument transformer, is one by poured with epoxy resin between described single-phase potential transformer, monophase current instrument transformer and the mounting seat.
As preferably, the distance between described single-phase potential transformer and the monophase current instrument transformer is 2-25mm.
As preferably, described mounting seat arranges two single-phase potential transformers and two monophase current instrument transformers, and described two single-phase potential transformers and two monophase current instrument transformers evenly arrange at interval, and spacing is 4-10mm.
As preferably, the distance between described adjacent two single-phase potential transformers is 3-8mm; Distance between adjacent two monophase current instrument transformers is 5-10mm.
As preferably, the bottom of described mounting seat is provided with mounting bracket, and described mounting bracket is fastenedly connected by fastening bolt and mounting seat; Also can select to peg graft by buckle-type between mounting bracket and the mounting seat, make things convenient for installation and maintenance, reduce maintenance cost and labour intensity.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model compact conformation is combined current transformer and voltage transformer, has reduced the cost of equipment installation and maintenance, has reduced taking up room, and has reduced working strength of workers, has very high practicality and promotional value.
