Description
Technical field
The utility model relates to transformer technology field, particularly a kind of holding down transformer body combined pad.
Background technology
The transformer (as rectifier transformer, furnace transformer) etc. of capacity power transformer big or middle and some special purposes, usually utilizes the nail pressing be fixed on top folder and curb girder, applies axial pressing force by insulation pressing to device body.Because window position unshakable in one's determination is without effective strong point, make the axial force skewness that three-phase device body circumferentially applies, this will have a strong impact on product shock resistance mechanical strength, jeopardize product safety reliability.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, a kind of holding down transformer body combined pad is provided, this cushion block can improve device experience power uniformity coefficient, prevent transformer body because of electromagnetic force vibrations or impact load produce electric power and loosen, thus avoid the upper and lower play of magnet wire cake to cause wire transposition place insulation wearing and tearing, form electric short circuit and damage transformer, the object strengthen product mechanical strength to reach, improving product safety reliability.
For solving the problem, the utility model provides following technical scheme:
A kind of holding down transformer body combined pad, comprises sliceable upper correcting wedge together and lower correcting wedge; Described upper correcting wedge and lower correcting wedge are the wedge of isolation material; Described upper correcting wedge is provided with splicing boss; Described lower correcting wedge is provided with and the splicing groove splicing boss and coordinate; The two ends of described upper correcting wedge and lower correcting wedge are equipped with semicircle open slot.
Further, described upper correcting wedge and lower correcting wedge are lamination wooden unit.
Further, described upper correcting wedge and lower correcting wedge are equipped with the slide guide face of inclination; Described upper correcting wedge is identical with the angle of inclination in the slide guide face on lower correcting wedge; Described splicing boss is shaped on the slide guide face of correcting wedge; Described splicing groove is shaped on the slide guide face of lower correcting wedge.
Further, the slide guide face of the end face level of described splicing boss on upper correcting wedge; The slide guide face of bottom surface level on lower correcting wedge of described splicing groove.
Further, in the mounted state, described splicing boss is inserted in splicing groove slidably, is provided with play gap between the sidewall of splicing boss and the sidewall of splicing groove.
Further, the edge, the place of outputing of described semicircle open slot is provided with chamfering.
Beneficial effect: a kind of holding down transformer body combined pad of the present utility model, adopt and increase the method that device body compresses point, improve unbalance stress phenomenon, increase transformer body integral rigidity, improve device body shock resistance mechanical strength, thus guarantee product can in lifetime long-term safety reliability service.Because this combined pad comprises upper correcting wedge and lower correcting wedge, formed by the splicing groove on the splicing boss on upper correcting wedge and lower correcting wedge and interlock, left and right play, the landing under external force of two correcting wedges can be prevented; The two ends of upper correcting wedge and lower correcting wedge are equipped with the semicircle open slot for installing insulating screw rod, and solve the problem of window position unshakable in one's determination without effective strong point, insulated bolt can prevent two correcting wedges in clamping direction displacement unshakable in one's determination, come off.

Embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
Referring to figs. 1 through a kind of holding down transformer body combined pad shown in Fig. 4, comprise sliceable upper correcting wedge 2 together and lower correcting wedge 3; Described upper correcting wedge 2 and lower correcting wedge 3 are the wedge of isolation material; Described upper correcting wedge 2 is provided with splicing boss 5; Described lower correcting wedge 3 is provided with and the splicing groove 6 splicing boss 5 and coordinate; The two ends of described upper correcting wedge 2 and lower correcting wedge 3 are equipped with semicircle open slot 7.
Described upper correcting wedge 2 and lower correcting wedge 3 are lamination wooden unit.
Described upper correcting wedge 2 and lower correcting wedge 3 are equipped with the slide guide face 4 of inclination; Described upper correcting wedge 2 is identical with the angle of inclination in the slide guide face 4 on lower correcting wedge 3; Described splicing boss 5 is shaped on the slide guide face 4 of correcting wedge 2; Described splicing groove 6 is shaped on the slide guide face 4 of lower correcting wedge 3.
The slide guide face 4 of end face level on upper correcting wedge 2 of described splicing boss 5; The slide guide face 4 of bottom surface level on lower correcting wedge 3 of described splicing groove 6.
In the mounted state, described splicing boss 5 is inserted in splicing groove 6 slidably, is provided with play gap between the sidewall of splicing boss 5 and the sidewall of splicing groove 6.
Wherein, when transformer body is subject to larger axis to power, the upper correcting wedge 2 of pressed laminated wood matter and lower correcting wedge 3 easily burst apart at splicing boss 5 or splicing groove 6 place, this play gap is that the Relative sliding between upper correcting wedge 2 and lower correcting wedge 3 provides slippage surplus, effectively avoids the generation of bursting apart.
The edge, the place of outputing of described semicircle open slot 7 is provided with chamfering 8.
Wherein, the effect of chamfering 8 is to be inserted into by insulated bolt in semicircle open slot 7 easily.
The utility model in use, first utilize hydraulic jack to withstand on device body and apply pretightning force, then the splicing boss 5 on upper correcting wedge 2 is inserted in the splicing groove 6 on lower correcting wedge 3, combined pad 1 entirety is put into window upper yoke unshakable in one's determination and the gap of single-phase device with it between pressing plate 10, upper correcting wedge 2 and lower correcting wedge 3 is beaten from both sides, make end face, finally, with two screw rods, wedge cushion block 1 is fixed on device pressing plate 10 with it, thus avoid magnet wire cake 9 because of device experience to loosen after power and up and down play cause wire transposition place to insulate wearing and tearing, form electric short circuit and damage transformer, product mechanical strength is strengthened to reach, improve the object of product safety reliability.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
