Abstract
The utility model relates to a corrugated expander, in particular to a corrugated expander for mutual inductors in laid transportation, which belongs to the technical field of mutual inductor manufacture. The technical scheme includes that the corrugated expander comprises a cover plate (3), a plurality of support screw rods (4), a corrugated sheet (5), an outer cover (6) and a bottom plate (7), the corrugated sheet is arranged between the cover plate and the bottom plate in the outer cover, the support screw rods are arranged along the circumference of the corrugated sheet, rubber cushion blocks arranged on the support screw rods contact with the corrugated sheet, and a limit guardrail (2) is further arranged in the outer cover. When the mutual inductors are in laid transportation process, the corrugated sheet cannot shake, and stability of the corrugated sheet is enhanced. When emergency brake or rapid starting is performed on the way, permanent deformation of the corrugated sheet of the expander is avoided by the aid of the limit guardrail. The expander is large in effective travel, can be oiled by means of vacuum pumping, is especially applicable to the mutual inductors in transportation, and solves the problem of damage to an expander caused by transportation.
Description
Technical field:
The utility model relates to a kind of bellow expander, and the instrument transformer bellow expander of the transportation of particularly droping to the ground belongs to instrument transformer manufacturing technology field.
Background technology:
The instrument transformer product of 220kV and above electric pressure adopts the transportation of droping to the ground, because the bellow expander corrugated plate is thinner, when occurring in the transportation jolting or during snub, causing that easily corrugated plate is out of shape, even oil leakage phenomenon occurs.
The utility model content:
The utility model purpose provides a kind of bellow expander, and the instrument transformer product fell when transportation, has avoided that corrugated plate is shaken up and down, the phenomenon of corrugated plate local deformation, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
A kind of bellow expander, comprise cover plate, studdle, corrugated plate, outer cover, base plate, corrugated plate is arranged in the outer cover, between cover plate and the base plate, along the corrugated plate circumference a plurality of studdles are set, rubber cushion blocks is set on studdle contacts, in instrument transformer is droped to the ground transportation, when the vertical direction vibration takes place with corrugated plate, corrugated plate can not shake, and has strengthened the stability of corrugated plate.
The utility model also is provided with spacing guardrail in outer cover, in instrument transformer is droped to the ground transportation, snub or when starting fast, transformer oil has had the limit protection hurdle just to avoid the permanent deformation of expander corrugated plate because inertia produces enormous impact power in the horizontal direction.
Cover plate is provided with triple valve, and triple valve connects vacuum tube and lubricating can, can vacuumize with oiling the utility model and handle.
It is dismantled and assembled with base plate that the expander ripple connects joint, and base plate is detachable, when making instrument transformer, is convenient to utilize separately the expander base plate to connect to annotate the specific purpose tool of draining the oil to the product vacuum oil with suppress leak test.
The utility model also is provided with the oil level inspection hole on outer cover, be convenient to observe oil level and change.
The beneficial effects of the utility model: simple in structure, easy to operate, in instrument transformer is droped to the ground transportation, when the vertical direction vibration takes place, corrugated plate can not shake, strengthened the stability of corrugated plate, when snub in the way or when starting fast, transformer oil has had the limit protection hurdle just to avoid the permanent deformation of expander corrugated plate because inertia produces enormous impact power in the horizontal direction.This expander effective travel is big, can realize the repairing that vacuumizes to expander, is specially adapted to be put into the instrument transformer product of transportation, has solved because transportation causes the difficult problem of expander damage.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Among the figure: triple valve 1, limit protection hurdle 2, cover plate 3, studdle 4, corrugated plate 5, outer cover 6, oil level inspection hole 7, base plate 8.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of bellow expander, comprise cover plate 3, studdle 4, corrugated plate 5, outer cover 6, base plate 7, corrugated plate is arranged in the outer cover, between cover plate and the base plate, along the corrugated plate circumference a plurality of studdles are set, rubber cushion blocks is set on studdle contacts, in instrument transformer is droped to the ground transportation, when the vertical direction vibration takes place with corrugated plate, corrugated plate can not shake, and has strengthened the stability of corrugated plate.The utility model also is provided with spacing guardrail 2 in outer cover, in instrument transformer is droped to the ground transportation, snub or when starting fast, transformer oil has had the limit protection hurdle just to avoid the permanent deformation of expander corrugated plate because inertia produces enormous impact power in the horizontal direction.Cover plate 3 is provided with triple valve 1, and triple valve connects vacuum tube and lubricating can, can vacuumize with oiling the utility model and handle.It is dismantled and assembled with base plate that the expander ripple connects joint, and base plate is detachable, when making instrument transformer, is convenient to utilize separately the expander base plate to connect to annotate the specific purpose tool of draining the oil to the product vacuum oil with suppress leak test.The utility model also is provided with oil level inspection hole 7 on outer cover, be convenient to observe oil level and change.
