Abstract

The utility model relates to a full sealed expansion radiator type oil conservator for a transformer, which comprises an expansion radiator, an oil collecting pipe and a valve. A traditional barrel-type oil conservator is replaced by the expansion radiator, which not only can regulate the volume change caused by the heat expansion and cold contraction of the transformer oil, but also has the function of radiation. A full sealed structure is used, which can prevent the transformer oil from wetting and pollution and can ensure the insulating performance of the oil. The utility model can be applied to various types of transformers.

Description

Transformer is with hermetically sealed Expansion radiator formula conservator

The utility model relates to a kind of transformer with hermetically sealed Expansion radiator formula conservator, belongs to transformer part.

Conservator is as parts of transformer, be used to regulate the volume-variation that produces when cold oil expands with heat and contract with cold in the oil tank of transformer, it typically is an oil drum made of iron, contain oil in the bucket and communicate with atmosphere, so very easily make moist with contaminated, will have a strong impact on the insulation property of oil.

The purpose of this utility model is to provide a kind of and can volume adjusted changes, and has heat sinking function again, and hermetic Expansion radiator formula conservator.

Transformer of the present utility model comprises Expansion radiator with hermetically sealed Expansion radiator formula conservator, last oil collecting pipe, following oil collecting pipe, pressure relief valve, Buchholz relay and impact non-return valve, described Expansion radiator comprises the radiator box, tie rod, limiting plate and arm, each radiator box is by two corrugated plating butt welding systems, each radiator box is arranged in parallel, be fixed as one group of Expansion radiator by tie rod 11, be positioned at inboard each corrugated plating (except the corrugated plating at two ends) center and be suppressed with the height of position consistency, low boss, on each radiator box, following two ends are communicated with last oil collecting pipe and following oil collecting pipe by arm respectively, and the limiting plate that can limit corrugated plating expansion yardstick is equipped with in the outer face of two radiator boxes of outermost end; Described pressure relief valve is installed on the oil collecting pipe; Described Buchholz relay is installed on the pipeline between oil collecting pipe and the oil tank of transformer; Described impact non-return valve is installed in down on the pipeline between oil collecting pipe and the oil tank of transformer.

Both the utility model has the advantages that and to regulate the volume-variation of expanding with heat and contract with cold and causing, had both heat sinking function again; Realize hermetically sealedly, prevented that transformer oil from making moist and contaminated; Increase boss and limiting plate, can make Expansion radiator bear bigger pressure and change; The transformer that can be used for new production also can be used for the transformer that moved, replaces old-fashioned conservator, and selects the Expansion radiator of not counting on the same group as required for use, promptly applicable to all kinds of transformers of large, medium and small type; Expansion radiator also can use separately, is installed on the transformer.

Embodiment: referring to Fig. 1-3, the utility model comprises Expansion radiator 1, last oil collecting pipe 2, following oil collecting pipe 5, pressure relief valve 4, Buchholz relay 6 and impacts non-return valve 8.Expansion radiator 1 is by radiator box 10, tie rod 11, limiting plate 13 and arm 9,15 constitute, each radiator box 10 is by two steel corrugated plating butt welding systems, be suppressed with the ripple of runway shape on the corrugated plating, four radiator boxes 10 are arranged in parallel, be fixed together by tie rod 11, form one group of Expansion radiator 1, there is T-shape limiting plate 13 outer face of two radiator boxes 10 of every group of Expansion radiator 1 outermost end, in the Expansion radiator 1, the centre that is positioned at each inboard corrugated plating is suppressed with two big boss 14 and a small boss 12, small boss 12 is positioned in the middle of two big boss 14, and the position consistency of every corrugated plating convex platform, after installing, big boss 14 is relative with big boss 14, small boss 12 is relative with small boss 12, when radiator box 10 expands, big boss 14 on the corrugated plating contacts with each other earlier, pressure continues to increase, small boss 12 contacts with each other, corrugated plating no longer expands, each radiator box 10 upper end is communicated with last oil collecting pipe 2 by arm 9, its lower end is communicated with following oil collecting pipe 5 by arm 15,4 groups of Expansion radiators 1 are a conservator, on the last oil collecting pipe 2 pressure relief valve 4 is housed, on the pipeline between last oil collecting pipe 2 and the oil tank of transformer 7 Buchholz relay 6 is housed, is equipped with on the pipeline between following oil collecting pipe 5 and the oil tank of transformer 7 and impacts non-return valve 8.3 is oil ga(u)ge among the figure.Fig. 4,5,6 is respectively the hermetically sealed Expansion radiator formula conservator of the transformer that is used for different model, as required, can adopt the Expansion radiator of not counting on the same group.
