Abstract
The utility model discloses a transformer body lower positioning structure of a power transformer. The transformer body lower positioning structure of the power transformer comprises a box bottom support plate and a lower clamping element, wherein a positioning nail is vertically welded on a box bottom, the diameter of an upper small head part of the position pin is smaller than the diameter of a lower big head part, a small head part of the position pin passes through and stretches outside a support plate hole which is arranged on the box bottom support plate, a small head insulating baffle plate and a pressure plate are arranged outside the small head part, the pressure plate is arranged above the small head insulating baffle plate, and a flat washer, a spring washer and a nut are orderly arranged above the small head part of the position pin. The box bottom is welded with the position pin, and the position pin is of a convex shape, and is made by turning cold-drawn round steels. A lower big head is chamfered on the bottom to increase a welding surface with the box bottom, and the upper small head is turned with a screw mouth. The transformer body lower positioning structure of the power transformer can achieve rigid positioning of a transformer body, is more reliable to position, and also can excellently achieve isolation and insulation between the clamping element and an oil tank.
Description
Technical field
The utility model belongs to the power equipment positioning field, relates to a kind of location structure, especially a kind of power transformer device body bottom location structure.
Background technology
Device body bottom Position Design was to weld locating pin at the bottom of case in the past, opened corresponding hole at the lower clamping piece lower carrier plate, and device body rear locating pin in place is deep in the corresponding plate hole.This structure can only play spacing effect, does not have locking device, so it can not realize the rigidity location of device body.In transportation, certain displacement can be produced, wearing and tearing and the distortion of part may be caused.And folder directly contacts by locating pin with fuel tank, when the ask for something folder is drawn ground connection by small casing, be difficult for realizing folder with at the bottom of the case between insulation, so this structure can only be used in the small-capacity product.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of power transformer device body bottom location structure is provided, and this structure forms with cold-drawn round steel car system.The bottom major part increases and solder side at the bottom of the case in bottom chamfer, got on the bus silk mouthful of top microcephaly.Can realize the rigidity location of device body, locate more reliably, can realize well isolated insulation between folder and the fuel tank again.
The purpose of this utility model solves by the following technical programs:
A kind of power transformer device body bottom location structure comprises support plate and lower clamping piece at the bottom of the case; Vertically be welded with locating pin at the bottom of the described case, top microcephaly's section diameter of described locating pin is less than bottom major part section diameter; The enlarged head of described locating pin exceptionally surface cover has paper tube, and the outside of described paper tube is equipped with the major part insulating barrier, and support plate is placed on the top of insulating barrier; The little head part of described locating pin is passed and is stretched out plate hole on the support plate, and the outside of little head part is equipped with microcephaly's insulating barrier and pressing plate, and pressing plate is arranged on the top of microcephaly's insulating barrier; The top of the little head part of described locating pin is disposed with plain washer, spring washer and nut.
Above-mentioned locating pin is for to form with cold-drawn round steel car system, and is the structure of " protruding " font.
Above-mentioned paper tube is insulating paper tube.
The major part part lower surface of above-mentioned locating pin bottom is provided with chamfering.
The utility model welds locating pin at the bottom of case, locating pin is " protruding " font, forms with cold-drawn round steel car system.The bottom major part increases and solder side at the bottom of the case in bottom chamfer, got on the bus silk mouthful of top microcephaly.Can realize the rigidity location of device body, locate more reliably, can realize well isolated insulation between folder and the fuel tank again.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein: 1 is nut; 2 is spring washer; 3 is plain washer; 4 is pressing plate; 5 is microcephaly's SI semi-insulation dividing plate; 6 is locating pin; 7 is paper tube; 8 is major part part insulating barrier; 9 be case at the bottom of; 10 is support plate; 11 is lower clamping piece.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, this power transformer device body bottom location structure comprises 9 support plates 10 and lower clamping piece 11 at the bottom of the case; Vertically be welded with locating pin 6 on 9 at the bottom of the described case, top microcephaly's section diameter of described locating pin 6 is less than bottom major part section diameter; The enlarged head of described locating pin 6 exceptionally surface cover has paper tube 7, and the outside of described paper tube 7 is equipped with major part insulating barrier 8, and support plate 10 is placed on the top of insulating barrier 8; The little head part of described locating pin 6 is passed and is stretched out plate hole on the support plate 10, and the outside of little head part is equipped with microcephaly's insulating barrier 5 and pressing plate 4, and pressing plate 4 is arranged on the top of microcephaly's insulating barrier 5; The top of the little head part of described locating pin 6 is disposed with plain washer 3, spring washer 2 and nut 1.Locating pin 6 is for to form with cold-drawn round steel car system, and is the structure of " protruding " font.Paper tube 7 is insulating paper tube.The major part part lower surface of locating pin 6 bottoms is provided with chamfering.
Concrete operations mode of the present utility model is as follows:
Weld locating pin at the bottom of case, locating pin is " protruding " font, forms with cold-drawn round steel car system.The bottom major part increases and solder side at the bottom of the case in bottom chamfer, got on the bus silk mouthful of top microcephaly.Put an insulating paper tube in the major part outside during assembling, then load onto insulating barrier, the little head part in device body upper back in place is passed and is stretched out lower clamping piece and prop up plate hole, loads onto respectively insulating barrier, keeper plate of steel, plain washer, spring washer and nut at extension, and final force square spanner is tightened.Load onto respectively cushion pad (the fine oil-resistant rubber slab of fourth) and " U " shape paper groove (insulating board) between at the bottom of iron core feet and the case, just formed so good insulation system between folder and the fuel tank, folder is drawn ground connection with cable by the small casing on the case lid, draw ground connection with iron core and walk to fuel tank bottom assigned position, make things convenient for the monitoring grounding electric current.
