Shockproof dry-type transformer

Technical Field

The utility model relates to a dry-type transformer technical field especially relates to a dry-type transformer takes precautions against earthquakes.

Background

The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and the main components are a primary coil, a secondary coil and a magnetic core, and the transformer is divided into a unidirectional transformer and a three-phase transformer. The dry type transformer is a transformer with an iron core and a winding which are not immersed in insulating oil, and is composed of an iron core composed of silicon steel sheets and coils cast by epoxy resin, and high-voltage and low-voltage coils are insulated. The traditional transformer does not have good anti-vibration performance, and the normal use of the transformer is easily influenced by the fact that the iron core vibrates and even shifts due to external force collision in the process that the transformer is transported independently or is transferred along with an electric appliance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the iron core in the prior art is easy to shift due to vibration, and providing a shockproof dry-type transformer.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a dry-type transformer takes precautions against earthquakes, includes inner shell, magnetic core and shell, the inside of inner shell is arranged in to the magnetic core, and the inboard of magnetic core is provided with the cross brace piece that matches with the magnetic core and fix with the inner shell, the outside packing of magnetic core has the shock attenuation filler, it has the stationary blade to establish the cooperation to insert on the cross brace piece, be fixed with the terminal on the magnetic core, and the coil of winding on the magnetic core is connected rather than the terminal that corresponds respectively, the shell cover is in the outside of inner shell.

Preferably, corner protection blocks matched with the magnetic core and fixed with the inner shell are arranged at four corners of the outer side of the magnetic core.

Preferably, a plurality of pin holes are formed in the cross bracing block, and a pin rod is integrally arranged on the fixing piece and is inserted into and matched with the pin holes.

Preferably, the upper side and the lower side of the shell are both provided with connecting holes, and the wiring terminal is positioned on the inner side of the shell.

Preferably, an elastic gasket is arranged between the inner shell and the outer shell.

Preferably, the inner shell and the outer shell are connected through a spring.

The utility model has the advantages that:

1. the utility model discloses a cross brace piece is fixed the magnetic core in the inside of inner shell, prevents to shift because the iron core that external force collision caused, improves the stability of transformer.

2. The outer shell is additionally arranged on the outer side of the inner shell, so that the collision of the transformer can be buffered, meanwhile, the binding post can be prevented from being collided, and the open circuit phenomenon is reduced.
