CN201859764U - Voltage transformer used in gas insulated metal-enclosed switchgear - Google Patents

Abstract

The utility model relates to the field of transformation, in particular to a voltage transformer used in gas insulated metal-enclosed switchgear. A primary coil connecting terminal A of the voltage transformer in the gas insulated metal-enclosed switchgear is connected with a primary coil, an iron core penetrates through the primary coil, and the primary coil is welded to a primary coil connecting terminal B after the number of through turns of the primary coil meets requirements. A secondary coil is wound on the rectangular iron core. An outgoing line of the secondary coil is welded to a secondary coil connecting terminal A and a secondary coil connecting terminal B. Epoxy resin is cast inside the voltage transformer. The voltage transformer is small in volume and convenient in installation and can be applied to the gas insulated metal-enclosed switchgear widely.

Description

A kind of voltage transformer that uses in the cabinet of inflating

Technical field

The utility model relates to the power transformation field, relates to a kind of voltage transformer that uses in the cabinet of inflating specifically.

Background technology

Inflating the employed voltage transformer of cabinet because the size shape of inner iron core and unreasonable the arranging that structure is arranged at present, make the voltage transformer volume inside can not obtain reasonable use, cause the volume of voltage transformer excessive, can not satisfy the requirement of user the product miniaturization.For this reason, we have developed a kind of small-sized voltage transformer of inflation cabinet that is exclusively used in to overcome the above problems.。

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model is that a kind of voltage transformer that uses in the cabinet of inflating will be provided, and improves the fail safe of inflation cabinet voltage transformer use and the simplification of installation.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of voltage transformer that uses in the cabinet of inflating comprises primary winding, secondary coil, primary winding binding post A, primary winding binding post B, iron core, epoxy resin, secondary coil splicing ear A and secondary coil splicing ear B.The primary winding binding post A of the voltage transformer that uses in the described inflation cabinet links to each other with primary winding, and primary winding passes iron core, meet the punching number of turn after, be welded on the primary winding binding post B; Secondary coil is wrapped on the iron core, and iron core is a rectangle; The outlet of secondary coil is welded on secondary coil splicing ear A and the secondary coil splicing ear B; The inner casting epoxy resin of voltage transformer.

Described voltage transformer is a full-closed structure.

The beneficial effects of the utility model are: the primary winding binding post A of the voltage transformer that uses in the described inflation cabinet links to each other with primary winding, and primary winding passes iron core, meet the punching number of turn after, be welded on the primary winding binding post B; Secondary coil is wrapped on the iron core, and iron core is a rectangle; The outlet of secondary coil is welded on secondary coil splicing ear A and the secondary coil splicing ear B; The inner casting epoxy resin of voltage transformer.This voltage transformer volume is little and easy for installation, can be widely used in inflating in the cabinet.
