Abstract

The utility model discloses an expansion typed radiator, which comprises an upper oil gathering pipe and a lower oil gathering pipe which are parallelly arranged; a radiator box is arranged between the upper oil gathering pipe and the lower oil gathering pipe; the upper end and the lower end of the radiator box are provided with openings which are respectively communicated with the upper oil gathering pipe and the lower oil gathering pipe; the radiator box with at least two opposite side walls is manufactured by ripple pieces; the upper ends and the lower ends of the ripple pieces are closed. As the both sides of the radiator box are provided the ripple pieces and the quantity and specification of the ripple pieces are not limited by the types of transformers, the radiator has the advantages of convenient maintenance, beautiful exterior, reliable operation and remarkably improved operating performance, thus being applicable to large and medium scaled fully-sealed distribution transformers.

Description

The expansion type radiator

Technical field

The utility model relates to a kind of expansion type radiator that is used for transformer.

Background technology

In the prior art, the hermetically sealed distribution transformer of oil immersed type, mostly be to hang [A1] dress fin in the two sides of its casing, wherein corrugated fin is relatively use always a kind of, though corrugated plate both can have been regulated the volume-variation that causes when transformer oil expands with heat and contract with cold, and possessed heat sinking function again, corrugated plate specification, sheet number are subjected to placing restrictions on the transformer type usually, range of choice is little, can't satisfy the needs of large and medium-sized product.

Summary of the invention

The utility model purpose is: a kind of expansion type radiator is provided, can be applicable to large and medium-sized hermetically sealed distribution transformer, and easy to maintenance, good looking appearance, reliable.

The technical solution of the utility model is: a kind of expansion type radiator, comprise the last oil collecting pipe and the following oil collecting pipe that be arranged in parallel, between last oil collecting pipe and the following oil collecting pipe radiator box is installed, the two ends up and down of radiator box are provided with opening and are communicated with last oil collecting pipe and following oil collecting pipe respectively, the radiator box has at least two relative sidewalls to make of corrugated plate, the top and bottom sealing of corrugated plate.

This is suitable for novel further technical scheme: a kind of expansion type radiator, comprise the last oil collecting pipe and the following oil collecting pipe that be arranged in parallel, between last oil collecting pipe and the following oil collecting pipe radiator box is installed, the two ends up and down of radiator box are provided with opening and are communicated with last oil collecting pipe and following oil collecting pipe respectively, the radiator box has at least two relative sidewalls to make of corrugated plate, the top and bottom sealing of corrugated plate; The U-shaped plate of two sidewalls in addition for vertically being oppositely arranged of described radiator box, corrugated plate is connected between the edge of two U-shaped plates.

The utility model advantage is:

1. the oil collecting pipe of going up of the present utility model can be communicated with transformer respectively with following oil collecting pipe, and both sides are equipped with corrugated plate, have swelliong power, can regulate the change in volume that transformer oil expands with heat and contract with cold and causes.

2. the utility model is not limited by transformer specification, applicable to polytype transformer.

Wherein: oil collecting pipe on 1; 2 times oil collecting pipes; 3 radiator boxes; 4 corrugated plates; 5 air relief cocks; 6 bleeder plugs; 7 flanges; 8U shape plate.

Embodiment

Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of expansion type radiator, comprise the last oil collecting pipe 1 and the following oil collecting pipe 2 that be arranged in parallel, last oil collecting pipe 1 and following oil collecting pipe 2 can directly be welded on the transformer-cabinet, also can be communicated with transformer by flange 7, the convenient dismounting of radiator in transit of this mounting means, last oil collecting pipe 1 top is provided with the air relief cock 5 of exhaust when being used for the radiator oiling, following oil collecting pipe 2 bottoms are provided with bleeder plug 6 and are used for radiator and drain the oil, last oil collecting pipe 1 and following oil collecting pipe 2 sides are equipped with opening, be provided with radiator box 3 between last oil collecting pipe 1 and the following oil collecting pipe 2, the two ends up and down of radiator box 3 are provided with opening and are communicated with last oil collecting pipe 1 and following oil collecting pipe 2 respectively, the U-shaped plate 8 of two sides of described radiator box 3 for vertically being oppositely arranged, both sides U-shaped plate 8 connects by the corrugated plate 4 that is welded on its forward position, the welded closure of two ends up and down of corrugated plate 4, constitute two other side of radiator box 3, radiator box 3 upper and lower sides are opening, dock with last oil collecting pipe 1 and following oil collecting pipe 2 upper sheds respectively, last oil collecting pipe 1 and following oil collecting pipe 2 are communicated with by radiator box 3.

During operation, deep fat in the transformer flows into goes up oil collecting pipe 1, and by in the last oil collecting pipe 1 inflow radiator box 3, the change in volume that the corrugated plate 4 of radiator box 3 both sides produced in the time of both can having regulated transformer oil and expand with heat and contract with cold, can quicken the cooling of transformer oil again, cooled transformer oil passes through in following oil collecting pipe 2 inflow transformers.

The both sides of radiator box 3 of the present utility model are provided with corrugated plate 4, the quantity of corrugated plate 4 and specification are not subjected to the restriction of transformer type, and easy to maintenance, good looking appearance is reliable, significantly improve its serviceability, can be applicable to large and medium-sized hermetically sealed distribution transformer.
