Description

Dry-type transformer

Technical Field

The utility model relates to a power equipment technical field especially relates to a dry-type transformer.

Background

A transformer is widely used in daily life, which is a stationary electric appliance that converts one level of voltage and current into another level of voltage and current of the same frequency between two or more coils using the principle of electromagnetic induction and transmits electric energy. Transformers are classified into oil-immersed transformers, fully-sealed transformers, combined transformers, and dry-type transformers. Among them, the dry type transformer is widely used in the places of local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and the like, and simply, the dry type transformer refers to a transformer in which an iron core and a winding are not immersed in insulating oil. When carrying, installation or the wind-force of outside is great, the influence causes dry-type transformer easily and can last vibrations, thereby dry-type transformer lasts vibrations and can cause the fixed part of dry-type transformer not hard up, and then leads to dry-type transformer to appear damaging to dry-type transformer lasts vibrations and can make dry-type transformer easy working failure, causes the circuit trouble, influences the circuit and uses, and practical application effect is relatively poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned drawbacks, an object of the present invention is to provide a dry-type transformer with stable structure and reduced swing, which can reduce the swing impact of the dry-type transformer and effectively prolong the service life of the dry-type transformer.

In order to achieve the above object, the utility model discloses a following technical scheme realizes: the dry-type transformer comprises a transformer body and a shell, wherein the transformer body is arranged inside the shell; the transformer comprises a transformer body, a supporting base, a hoisting top seat and a hoisting top seat, wherein the supporting base is arranged at the bottom of the transformer body and is arranged above the bottom of a shell; the upper and lower both sides of transformer body all are equipped with recess I, support base and hoist and mount footstock all be equipped with I assorted arch of recess, be equipped with recess II in the arch, be equipped with the spring between transformer body and the support base and between transformer body and the hoist and mount footstock respectively, the one end of spring is fixed in recess I, the other end of spring is fixed in recess II.

Preferably, the diameter of the protrusion is smaller than or equal to that of the groove I.

Preferably, a closing door is arranged on one side of the shell.

Preferably, foot pads are arranged at four corners of the bottom of the shell.

Preferably, the top of the shell is symmetrically provided with hoisting clamping plates, and the outer wall of each hoisting clamping plate is provided with hoisting insertion holes.

The utility model has the advantages that: the transformer body is symmetrically fixed with the supporting base and the hoisting top seat through the springs, so that the upper surface and the lower surface of the transformer body are symmetrically compressed under the same stress, a good buffering effect is achieved, swinging impact to the transformer body is reduced, and the service life of the dry-type transformer is effectively prolonged.
