Description

Energy-saving 10kV amorphous alloy power transformer

Technical Field

The utility model relates to a transformer structure especially relates to an energy-saving 10kV metallic glass power transformer.

Background

Amorphous Metal transformers (amorpus Metal transformers) are a low loss, energy efficient power Transformer. The transformer uses iron-based amorphous metal as an iron core, and because the material has no long-range ordered structure, the material is easier to magnetize and demagnetize than common magnetic materials. Therefore, the iron loss (i.e., no-load loss) of the amorphous alloy transformer is 70-80% lower than that of the conventional transformer using silicon steel as the iron core. Because the loss is reduced, the power generation requirement is also reduced, and the emission of greenhouse gases such as carbon dioxide is also reduced correspondingly. Amorphous alloy transformers are used in large-scale developing countries such as china and india in a large scale, based on energy supply and environmental protection factors. The current power consumption of the China and the seal country is used for calculation, if the amorphous alloy transformer is adopted on the whole distribution network, the power generation amount of 25-30TWh can be saved every year, and the emission of 2-3 million tons of carbon dioxide can be reduced.

Traditional metallic glass distribution transformer includes the oil tank, and this oil tank bottom is provided with the base, and the surface of oil tank is provided with corrugated radiator, is provided with the case lid at the oil tank top, and rings have been arranged to the case lid, and traditional rings adopt welded mode to be fixed in on the case lid usually, can't dismantle, then the hoist and mount in the later stage of being not convenient for after damaging.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing an energy-saving 10kV metallic glass power transformer, the oil tank comprises an oil tank, the oil tank bottom is equipped with the base, the oil tank surface is equipped with the radiator, the oil tank top is equipped with the case lid, the upper wall of radiator is equipped with a plurality of screw holes, and is a plurality of threaded holes spiro union has the traveller, the cover is equipped with reset spring on the traveller, traveller upper portion with the case lid meets, it has spacing frame to go up the traveller, spacing frame crimping is in on the reset spring, the spacing groove has been seted up on the case lid, the spacing inslot is equipped with rings, rings include rings body, rings seat is the L shaped plate, rings seat's outer wall with spacing frame inner wall meets.

Preferably, the upper surface of the oil tank is provided with a step, and a tank cover is fixed on the step.

Preferably, the inner wall of the suspension ring seat is connected with the outer wall of the step.

Preferably, the step height is adapted to the hanger ring seat thickness.

Preferably, the upper surface of the oil tank and the upper wall of the radiator have a height difference, and the thickness of the limiting frame and the compression limit height of the return spring are matched with the height difference.

Compared with the prior art, the utility model discloses following beneficial effect has:

through spacing frame can be quick with rings locking on the transformer, thereby can be right the transformer hoists, and rings when damaging, can be fast convenient change rings, can relax after the transformer is placed the assigned position take off rings, maintenance that carries on that can be better, when needs take out again when then.

Drawings

Fig. 1 is an overall structure diagram of the present invention.

Fig. 2 is an explosion structure diagram of the present invention.

Fig. 3 is a partial enlarged view of the present invention.

The figure is as follows: the oil tank comprises a tank cover 1, a lifting ring body 2, a limiting frame 3, a radiator 4, a base 5, a limiting groove 6, a sliding column 7, a return spring 8, a lifting ring seat 9, a threaded hole 10, steps 11, the upper surface of an oil tank 12 and an oil tank 13.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1-3, an energy-saving type 10kV amorphous alloy power transformer comprises an oil tank 13, wherein a base 5 is arranged at the bottom of the oil tank 13, a radiator 4 is arranged on the outer surface of the oil tank 13, a step 11 is arranged on the upper surface 12 of the oil tank 13, and a tank cover 1 is fixed on the step 11;
