Description

Transformer wooden cushion block

Technical Field

The utility model relates to a transformer wooden block.

Background

The transformer is a device for changing alternating voltage by utilizing the principle of electromagnetic induction, most transformers applied to municipal engineering are oil-immersed transformers, cooling oil in the existing oil-immersed transformers is discharged from an oil duct after being cooled, and then directly flows back to an oil tank through a wood cushion block arranged at the oil duct, so that the heated cooling oil does not have time to be naturally cooled, the temperature of the cooling oil flowing back to the oil tank slowly rises, the cooling effect is finally influenced, even the transformer fails, and further improvement is waited.

SUMMERY OF THE UTILITY MODEL

To the current situation of above-mentioned prior art, the utility model aims to solve the technical problem that a transformer wooden block that enables the effectual natural cooling of coolant oil in order to guarantee the cooling effect is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the transformer wood cushion block comprises a body and is characterized in that two first oil guide groove combinations which are symmetrically distributed are arranged in the middle of one side of the body, each first oil guide groove combination comprises a plurality of first oil guide grooves which are parallel to each other and are distributed at equal intervals, two second oil guide groove combinations which are symmetrically distributed are arranged at two ends of the body, each second oil guide groove combination comprises a plurality of second oil guide grooves which are parallel to each other and are distributed at equal intervals, the second oil guide grooves and the first oil guide grooves are mutually and vertically distributed, and the inner end of each second oil guide groove is mutually communicated with one first oil guide groove at the outermost side in one first oil guide groove combination at the same side; the width of first oil groove and the second oil groove of leading is 15mm, the degree of depth that first oil groove and the second oil groove of leading is 13 mm.

Preferably, the distance a between the innermost sides of the two first oil guide groove combinations is 20 mm.

Preferably, a notch is formed in the middle of one side of the body; and through holes which are symmetrically distributed are formed in the two ends of the other side of the body.

Compared with the prior art, the utility model has the advantages of: the utility model discloses be equipped with a plurality of first oil grooves and the oil groove is led to a plurality of seconds of leading, after the cooling oil after the cooling comes out from the oil duct, must lead oil groove and a plurality of second at a plurality of first oil grooves of leading and flow each other between the oil groove, then in the oil tank that flows back again, the cooling oil is at the flow in-process, its heat can outwards give off, and then effectual natural cooling, thereby make the cooling oil temperature that flows back in the oil tank remain throughout at the certain limit, guaranteed the cooling effect in order to avoid the transformer to break down.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 to 3, a transformer wood block comprises a body 1; two first oil guide groove combinations which are symmetrically distributed are arranged in the middle of one side of the body 1, each first oil guide groove combination comprises a plurality of first oil guide grooves 11 which are parallel to each other and are equidistantly distributed, two second oil guide groove combinations which are symmetrically distributed are arranged at two ends of the body 1, each second oil guide groove combination comprises a plurality of second oil guide grooves 12 which are parallel to each other and are equidistantly distributed, the second oil guide grooves 12 are mutually and vertically distributed with the first oil guide grooves 11, and the inner end of each second oil guide groove 12 is mutually communicated with one first oil guide groove 11 on the outermost side in one first oil guide groove combination on the same side; a gap 14 is arranged in the middle of one side of the body 1; both ends of the other side of the body 1 are provided with through holes 13 which are symmetrically distributed; the widths of the first oil guide groove 11 and the second oil guide groove 12 are both 15mm, and the depths of the first oil guide groove 11 and the second oil guide groove 12 are both 13 mm; the distance a between the innermost sides of the two first oil guide groove combinations is 20 mm.

When the transformer three-phase coil is used, the two bodies 1 are respectively arranged at the leftmost side and the rightmost side of the transformer three-phase coil and are respectively matched with oil ducts positioned at the leftmost side and the rightmost side, and meanwhile, the notch 14 is matched with a corresponding structure on the transformer; the temperature of the cooling oil after cooling the transformer rises, then the cooling oil flows to the upper part of the body 1 after coming out of the oil channel, then the cooling oil flows between the first oil guide grooves 11 and the second oil guide grooves 12, and finally the cooling oil flows outwards and drops into the oil tank, and the cooling oil in the oil tank flows back to the transformer to be cooled again under the action of the circulating device, so that a circulation is formed.

The utility model discloses be equipped with a plurality of first oil grooves 11 and a plurality of second oil grooves 12 of leading, after the cooling oil after the cooling comes out from the oil duct, must lead oil groove 11 and a plurality of second at a plurality of first oil grooves and lead and flow each other between oil groove 12, then flow back to the oil tank in again, the cooling oil is at the flow in-process, its heat can outwards give off, and then effectual natural cooling, thereby make the cooling oil temperature that flows back to in the oil tank remain throughout at the certain limit, guaranteed the cooling effect in order to avoid the transformer to break down.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
