Abstract

The utility model discloses a transformer which comprises a high-voltage winding, a low-voltage winding, an oil tank and a transformer body. The transformer body is vertically fixed at the bottom of the oil tank. An insulating device for potential insulation is arranged between the high-voltage winding and the low-voltage winding. The transformer not only is small in structural size but also can meet the power supply requirements of a residential area, a countryside power grid and the like.

Description

Transformer

Technical field

The utility model relates to field transformer, especially relates to a kind of transformer of small volume.

Background technology

Transformer (Transformer) is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.By purposes, can be divided into: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.

Western developed country and Southeast Asia, the South and North America area, used the little three-phase transformer of pole as distribution transformer in a large number.In supplying the distribution network of electrodispersion, the little phase transformer of pole has larger advantage as distribution transformer.It can reduce the length of low-voltage distributing line, reduces line loss, improves power supply quality.Along with the demand of present residential electricity consumption and urban construction, the length of low-voltage distributing line, reduce line loss, improves power supply quality, and capital expenditure is dwindled, and reduces noise and become now the most important thing of electrical network, and existing structure as shown in Figure 1.

The utility model content

The utility model purpose is to provide a kind of structure little, meets residential block, the transformer device structure of rural area net power demands.

The technical solution of the utility model is as follows:

A kind of transformer, comprise high pressure winding, low pressure winding, fuel tank and device body, and described transformer body is the vertical fuel tank bottom that is fixed on, and has the seal for potential isolation between described high pressure winding and low pressure winding.

In order to be that the structure of transformer is compacter, described fuel tank is drum type brake; Described fuel tank bottom is provided with a screw; Between described device folder from top to bottom with it, be provided with feet.

The beneficial effects of the utility model are:

Adopted energy-efficient volume core construction design, the characteristics of this transformer are to adopt pole to hang mounting means, and volume is little, and capital expenditure is little, reduces radius of low voltage power supply, can reduce Low-voltage Line Loss more than 60%.The transformer adopting all-sealed structure, capability of overload is strong, and operational reliability is high continuously, safeguards simple.Be applicable to dispersed supplying charge formula, have energy-saving effect preferably.Be applicable to rural power grids, remote mountain areas, disperse village, agricultural production, and illumination and power electricity consumption, also can be used for railway, urban distribution network reducing energy consumption pole distribution line.Between described high pressure winding and low pressure winding, having seal for potential isolation can reduce or prevent outside partial discharge fully.

Embodiment

Below to of the present utility model, to further illustrate by reference to the accompanying drawings.

A kind of transformer, comprise high pressure winding, low pressure winding, fuel tank 1 and device body 2 as shown in Figure 2, and described transformer body 2 is vertical fuel tank 1 bottoms that are fixed on, and has the seal for potential isolation between described high pressure winding and low pressure winding; Described fuel tank 1 is drum type brake; Described fuel tank 1 bottom is provided with a screw 3; Between folder from top to bottom 4 on described device body 2, be provided with feet 5.

Device body 2 use folders are fixed, and then put feet 5 between folder from top to bottom 4, the screw 3 of burn-oning in the bottom of drum type brake fuel tank 1 inwall, be positioned at whole device body 2 (comprising folder) on this screw 3.
