Abstract
The invention relates to a transformer body compression process, and belongs to the technical field of manufacturing of large transformer. The technical scheme includes that one end of an oil filling hose (3) is connected with a hydraulic pump, the other end of the oil filling hose is arranged between an upper pressing plate (1) and a lower pressing plate (2) of a transformer; the process includes charging initial pressure to the oil filling hose by a hydraulic pump provides; adding a filler between the upper pressing plate and the lower pressing plate after finishing charging; discharging oil in the oil filling hose, removing clamps, pulling out the oil filling hose, and adding filler at the position of the oil filling hose; and finally removing the oil filling hose to complete the transformer body compression process. The transformer body compression process has the advantages that pressure applied to the whole coil is uniform so that the coil is uniform in stress and has good compression effect; particularly, the coil is compressed by expansion of the oil filling hose which is charged by the hydraulic pump and placed between the upper pressing plate and the lower pressing plate of the transformer, and filling braces are uniformly distributed on the whole plane of the pressing plates so that compression effect of the coil can be guaranteed completely.
Description
Technical field
The present invention relates to a kind of device body pressing process of transformer, belong to high-power transformer manufacturing technology field.
Background technology
In the manufacture process of large-scale power transformer, need to compress operation to transformer body, background technology is exerted pressure inhomogeneous to whole coil, makes coil stressed also inhomogeneous, the distribution of stay on whole pressing plate plane of filling is also inhomogeneous, and it is bad that coil compresses effect.
Summary of the invention
The purpose of this invention is to provide a kind of device body pressing process of transformer, whole coil is exerted pressure evenly, make coil stressed evenly, coil compresses effective, solves the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of device body pressing process of transformer comprises following processing step:
2. an end of oil-filled flexible pipe is connected with the hydraulic pump group, and the other end is arranged between the top board and lower platen of transformer, and the anchor clamps by the end clamp shutoff to oil-filled hose end; With aspiration pump that air in the oil-filled flexible pipe is emptying, be pressurized to initial pressure for oil-filled flexible pipe by hydraulic pump;
Treat that the top board of transformer and lower platen propped up after the slit by oil-filled flexible pipe, measure between top board and lower platen apart from a, between oil-filled flexible pipe and the lower platen cardboard is set, the thickness of cardboard is h, the oil-filled rear height t of oil-filled flexible pipe, t=a+h, oil-filled rear height t according to oil-filled flexible pipe is determined corresponding coefficient k, to the pressure p 1 that oil-filled flexible pipe is exerted pressure again, p1=k * t, then continuing increases pressure to oil-filled flexible pipe, reaches p1; Repeat above-mentioned steps, measure the distance between top board and lower platen, determine next time applied pressure p2; The like, until again after the pressurization, the distance between top board and lower platen no longer changes, simultaneously, the whole coil height meets the requirements or exerts pressure and reaches the upper limit 3.0 MPa, the two one of satisfies and namely to stop pressurization;
Pressurize complete after, between top board and lower platen, add filler; Then anchor clamps are removed in oily emptying with in the oil-filled flexible pipe, and oil-filled flexible pipe is withdrawn from, and add filler in the position with oil-filled flexible pipe; Then withdraw from oil-filled flexible pipe, the holding down transformer body process finishes.
Described oil-filled flexible pipe quantity is 8, runs through between the whole top board of transformer and the lower platen, and whole coil is evenly exerted pressure.
The thickness of described cardboard is h, and h equals 6mm; It is complete to pressurize, and keeps beginning to add filler after 15 minutes again, and filler is stay.
Good effect of the present invention: whole coil is exerted pressure evenly, make coil stressed evenly, coil compresses effective, the oil-filled flexible pipe of the middle placement of top board, lower platen at transformer, make it expand to reach the purpose of coil pressing by hydraulic pump to oil-filled flexible pipe pressurization, fill stay and be evenly distributed on whole pressing plate plane, can guarantee fully that coil compresses effect.

Among the figure: top board 1, lower platen 2, oil-filled flexible pipe 3, cardboard 4.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described by embodiment.
A kind of device body pressing process of transformer comprises following processing step:
2. an end of oil-filled flexible pipe 3 is connected with the hydraulic pump group, and the other end is arranged between the top board 1 and lower platen 2 of transformer, and the anchor clamps by the end clamp shutoff to oil-filled hose end; With aspiration pump that air in the oil-filled flexible pipe is emptying, be pressurized to initial pressure for oil-filled flexible pipe by hydraulic pump;
Pressurize complete after, between top board and lower platen, add filler; Then anchor clamps are removed in oily emptying with in the oil-filled flexible pipe, and oil-filled flexible pipe is withdrawn from, and add filler in the position with oil-filled flexible pipe; Then withdraw from oil-filled flexible pipe, the holding down transformer body process finishes.
Described oil-filled flexible pipe quantity is 8, runs through between the whole top board of transformer and the lower platen, and whole coil is evenly exerted pressure.Described oil-filled rear height t according to oil-filled flexible pipe is determined corresponding coefficient k, and concrete corresponding relation is seen accompanying drawing 2.
The thickness of described cardboard is h, and h equals 6mm; It is complete to pressurize, and keeps beginning to add filler after 15 minutes again, and filler is stay.
