Abstract
The utility model relates to a no-load voltage regulation switch shielding cylinder structure, belonging to the technical field of transformers. According to the technical field, the structure comprises a no-load switch (1), an insulating cylinder I (2), a support strip I (3), a shielding cylinder (4), an insulating cylinder II (5), a support strip II (6) and an insulating cylinder III (7), wherein the insulating cylinder I, the support strip I, the shielding cylinder, the insulating cylinder II, the support strip II and the insulating cylinder III are sequentially arranged on the outer side of the no-load switch from inside to outside; and a lead-out wire of the shielding cylinder (4) is connected with a branching wire of the no-load switch (1) by cold pressing. The no-load voltage regulation switch shielding cylinder structure provided by the utility model has the beneficial effects that since the insulating cylinders, the support strips and the shielding cylinder are additionally arranged on the outer side of the no-load switch, the insulating distance from a switch contact to a coil is increased, the insulation reliability of the transformer is improved, compact arrangement is realized, the design cost is reduced, the insulation distance from the contact of a no-load voltage regulation switch of a single-phase high-voltage large-capacity transformer to a high-voltage coil is ensured, and a structure scheme is provided for increasing the insulation distance between a no-load voltage regulation switch and a coil.
Description
Technical field
The utility model relates to a kind of No-load changer switch shielding barrel structure, belongs to the transformer technology field.
Background technology
The no load switch of single-phase, high voltage large capcity transformer adopting, because the contact diameter of switch is little, switch is little to the insulation margin of high-tension coil, existing problems are: switch contact is lacked to the insulation distance of coil, and the insulating reliability of depressor is poor.
The utility model content
The purpose of the utility model provides a kind of No-load changer switch shielding barrel structure, improves transformer insulated reliability, realizes compact Layout, reduces cost, and solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of No-load changer switch shielding barrel structure; Comprise no load switch, insulating cylinder one, stay one, shielding cylinder, insulating cylinder two, stay two and insulating cylinder three, the no load switch outside sets gradually insulating cylinder one, stay one, shielding cylinder, insulating cylinder two, stay two and insulating cylinder three from inside to outside.
The lead-out wire of shielding cylinder and the line of no load switch are colded pressing and are linked together.
The good effect of the utility model: the no load switch outside increases insulating cylinder, stay, shielding cylinder; Increase the insulation distance of switch contact to coil; Improve the insulating reliability of transformer, realized compact Layout, reduced design cost; Guaranteed single-phase, high voltage large capcity transformer No-load changer switch contact insulation distance, for the insulation distance that improves No-load changer switch and coil provides organization plan to high-tension coil.
