Abstract
The invention discloses a support structure for controlling boundary dimensions of a dry variable pouring coil. The structure comprises a support plate, a reinforcing plate and compression bolts. The upper end of the support plate is arranged on the pressing plate of a pouring mold, and the lower end of the support plate is arranged on the baseplate of the pouring mold. The inner side face of the reinforcing plate abuts against the outer side of the straight line portion of the dry variable coil. A group of compression bolts are arranged on the support plate and the end portions of the compression bolts abut against the outer side face of the reinforcing plate. The support structure for controlling the boundary dimensions of the dry variable pouring coil is simple in structure, can effectively control the dimensions of the straight line portion of the coil, and enables the poured coil to meet requirements and meet performance indexes.
Description
Technical field
The invention belongs to transformer manufacture technology, relate to a kind of cast of dry-type transformer, specifically a kind of for controlling the stretching structure of doing change molded coil overall dimension.
Background technology
Existing epoxy-resin filled dry transformer coil substantially all adopts oval structure, due to oval coil surrounding discontinuity, thereby the easy resilience of straight line portion, be outer arch, cause overall dimension to exceed standard-required.After cast, the coil straight line portion is ship shape, the outside network for location that reveals of coil, on performance because reduced main insulating structure, sound super large during withstand voltage test, more serious will causing punctures; The easy super large of load loss value in addition, impedance voltage also can exceed standard.
Summary of the invention
The problem that exists in order to overcome prior art, the purpose of this invention is to provide a kind of stretching structure for controlling dried change molded coil overall dimension, this structure is simple in structure, effectively control coil straight line portion size, after making cast, coil reaches requirement, satisfies performance index.
The objective of the invention is to be achieved through the following technical solutions:
A kind of stretching structure for control to do becoming molded coil overall dimension, it is characterized in that: this structure comprises fagging, stiffener and hold-down bolt, and described fagging upper end is arranged on the pressing plate of casting mold, and the lower end is arranged on the base plate of casting mold; The medial surface of stiffener abuts in the outside of dried type transformer coil cathetus part; One group of hold-down bolt is arranged on fagging and the end of hold-down bolt is pressed on the lateral surface of stiffener.
In the present invention, be equipped with elongated slot on the pressing plate of casting mold and base plate, the top and bottom of fagging all are inserted in elongated slot.
Be provided with screwed hole on fagging, hold-down bolt is pressed on stiffener by the screwed hole ecto-entad.Be provided with 6 hold-down bolts on one-sided fagging, and 6 hold-down bolts axially are three row's two row layouts along fagging.
With equal cutting elongated groove on base plate, the centre adds a fagging, bores several screwed holes on fagging at the pressing plate of casting mold in the present invention, with hold-down bolt from outside compress inward stiffener on cast template.
Compared with prior art, the present invention is simple in structure, has prevented from being outer arch because of what the straight line portion resilience caused, can effectively control the straight line portion size, make cast after coil reach requirement, satisfy performance index.
