The flange sealing surface structure has relatively small mounting hole distance, but a sealing ring is also required to be arranged in the flange sealing surface structure, the cementing process is complex, and the sealing stability is lower than that of ceramic surface sealing.
The utility model aims to solve the technical problem that overcome prior art's defect, provide a mounting hole apart from the porcelain face seal structure the same with flange face is sealed. The ceramic surface sealing device can meet the requirement of smaller mounting hole distance and has a stable ceramic surface sealing mode.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the flange formula transformer porcelain bushing mucilage binding structure that proposes, the utility model discloses set up mucilage binding location step on porcelain bushing, after the mucilage binding was accomplished, flange and porcelain bushing combine closely, have reduced the mounting hole apart from the size. Meanwhile, the cementing positioning step plays a role in a ceramic sealing surface, so that the structural design can reduce the size of the mounting hole pitch and provide a stable ceramic surface sealing mode.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a flange type transformer porcelain bushing cementing structure comprises a porcelain bushing, wherein the porcelain bushing comprises a porcelain bushing cementing position, a cementing positioning step and a porcelain sealing surface, the flange comprises a flange cementing position, a flange contact surface and a flange bottom surface, and the cementing positioning step of the porcelain bushing is tightly matched with the flange contact surface through grinding;
according to the technical scheme, the cementing positioning step of the ceramic sleeve is ground, so that the contact surface of the flange is tightly matched with the cementing positioning step, the gap between the flange cementing position and the ceramic sleeve cementing position is filled with the adhesive, and the flange and the ceramic sleeve form a whole after curing.
Furthermore, the size of the cementing positioning step can be tightly matched with the contact surface of the flange by grinding;
through the technical scheme, the cementing positioning step is ground, so that the diameter of the outer edge of the cementing positioning step is 0.3-0.5mm smaller than that of the contact surface of the flange, and the cementing positioning step and the flange are in a close fit state.
Further, a sealing ring placed between the transformer box body and the porcelain sealing surface is extruded through the porcelain sealing surface to seal;
through the technical scheme, after the ceramic sleeve and the flange are arranged, the gap between the ceramic sleeve and the flange is filled with the adhesive.
Furthermore, the contact surface of the flange is smooth and burr-free, and the gap between the flange and the cementing positioning step in the porcelain bushing is less than one millimeter.
Further, a gap between the flange and the porcelain sleeve is filled with an adhesive;
according to the technical scheme, the adhesive is cement or epoxy resin.
The utility model discloses following beneficial effect has:
the utility model provides a flange formula transformer bushing mucilage binding structure, the utility model discloses set up mucilage binding location step on bushing, after the mucilage binding was accomplished, flange and bushing combine closely, have reduced the mounting hole apart from the size. Meanwhile, the cementing positioning step plays a role in a ceramic sealing surface, so that the structural design can reduce the size of the mounting hole pitch and provide a stable ceramic surface sealing mode.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides an embodiment: a flange type transformer porcelain bushing cementing structure comprises a porcelain bushing 1, wherein the porcelain bushing 1 comprises a porcelain bushing cementing position 11, a cementing positioning step 12 and a porcelain sealing surface 13, a flange 2 comprises a flange cementing position 21, a flange contact surface 22 and a flange bottom surface 23, the cementing positioning step 12 of the porcelain bushing 1 is tightly matched with the flange contact surface 22 through grinding, the flange contact surface 22 is tightly matched with the cementing positioning step 12 of the porcelain bushing 1 through grinding, a gap between the flange cementing position 21 and the porcelain bushing 1 cementing position is filled with a cementing agent 3, and the flange 2 and the porcelain bushing 1 form a whole after solidification.
The size of the cementing positioning step 12 can be tightly matched with the flange contact surface 22 through grinding, a sealing ring which is placed between the transformer box body and the ceramic sealing surface 13 is extruded through the ceramic sealing surface 13 to seal, the surface of the flange contact surface 22 is smooth and has no burrs, the gap between the flange contact surface 22 and the cementing positioning step 12 in the ceramic sleeve 1 is less than one millimeter, the gap between the flange 2 and the ceramic sleeve 1 is filled with a cementing agent 3, the cementing positioning step 12 is ground to enable the diameter of the outer edge of the cementing positioning step to be less than 0.3-0.5mm of the diameter of the flange contact surface 22, so that the cementing agent 3 is filled in the gap between the ceramic sleeve 1 and the flange 2 after the ceramic sleeve 1 and the flange 2 are arranged, and the cementing agent 3 is cement or epoxy resin.
