Description
Technical Field
The utility model relates to a parallelly connected large capacity voltage transformer of many windings.
Background
The mutual inductor is also called instrument transformer, and is a general name of current mutual inductor and voltage mutual inductor. The high voltage can be changed into low voltage, and the large current can be changed into small current for measuring or protecting the system. With the rapid development of the power field, the demand for large-capacity transformers is increasing. Therefore, manufacturers need to comprehensively consider the quality and cost of raw materials to produce transformers with larger capacity. Due to the limitation of winding equipment and a processing technology, the wire of the mutual inductor cannot be linearly improved along with the increase of the capacity of the mutual inductor, but the smaller wire specification cannot meet the parameter requirement of the large-capacity mutual inductor. At present, the capacity of the mutual inductor is increased by generally adopting a mode of increasing the size of an iron core, the mode is limited by the overall size of a product, the capacity of the mutual inductor is also limited, and the increase of the overall size of the product also has little influence on installation and use.

Thus, the two coils of the first sub-winding and the second sub-winding are connected in parallel, and the capacity of the secondary coil can be doubled.
In this embodiment, the first sub-winding and the second sub-winding are sub-windings with the same specification.
In practice, the multi-winding parallel connection high-capacity voltage transformer further comprises a shell, the iron core, the primary side winding and the secondary side winding are arranged in the shell in a sealing mode, and the shell is provided with connecting terminals corresponding to the primary side winding and the secondary side winding respectively. The iron core, the primary side winding and the secondary side winding are respectively sealed in the shell in a gluing mode, and the mutual inductor is electrically connected through the wiring terminals. Still be provided with the connecting piece on the casing, in this embodiment the connecting piece is the bolt hole of setting on the casing, carries out fixed mounting through the bolt to the casing.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
