Abstract
The utility model relates to a formed insulation cup and belongs to the technical field of transformer equipment. The utility model adopts the following technical scheme: the formed insulation cup comprises a sleeve (1), a lead wire (2), a pressing nail (3), a transformer body pressing plate (4) and an insulation cup (5), wherein the lead wire (2) is mutually connected with the sleeve (1) through the transformer body pressing plate (4); the pressing nail (3) is arranged on the transformer body pressing plate (4) and parallel to the lead wire (2); the insulation cup (5) is made of insulating pulp and arranged between the pressing nail (3) and the transformer body pressing plate (4). The formed insulation cup has the benefits as follows: the insulation cup is made of the insulating pulp and arranged at the lower part of the pressing nail, so that creepage path between the lead wire and the pressing nail is increased, and the creepage distance from the lead wire to the pressing nail is ensured.
Description
Technical field
The utility model relates to a kind of profiled insulation cup, belongs to transformer equipment technical field.
Background technology
The lead-in wire of transformer inside, because it has fixing current potential, for guaranteeing the safe operation of transformer, must consider that lead-in wire has enough distances to the hardware of ground connection.The current potential of lead-in wire is higher, goes between poorer to the electric field situation of each several part, goes between larger to the distance of each several part.For 110kV lead-in wire end outlet structure transformer, because 110kV lead-out wire is to be connected with sleeve pipe after device body pressing plate.And in product design, be the anti-short circuit capability of raising product, pressing plate adopts metalwork nail pressing compressing structure.Lead-in wire is when the pressing plate, will consider between lead-in wire and nail pressing, at the creepage distance of clamp surface, to avoid in electric field, occurs surface creepage and creeping discharge phenomenon occurs.In the situation that improving as far as possible confined space utilance, how to improve the electric field situation of lead-in wire to nail pressing, to reduce the insulation distance of lead-in wire to nail pressing, become the task of top priority.
Utility model content
The utility model object is to provide a kind of profiled insulation cup, selects insulation paper pulp molding to make core insulator, solves the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of profiled insulation cup, comprise sleeve pipe, lead-in wire, nail pressing, device body pressing plate and core insulator, described lead-in wire is connected to each other with sleeve pipe after by device body pressing plate, nail pressing is arranged on device body pressing plate, be arranged in parallel with lead-in wire, the material of core insulator, for insulation paper pulp, is arranged between nail pressing and device body pressing plate.
The thickness of described core insulator is 3 millimeters.
The density of described core insulator is 0.9g/ cm
3(gram/cc).
The beneficial effects of the utility model are: use insulation paper pulp to make core insulator, be arranged on nail pressing bottom, increased lead-in wire to the creepage path between nail pressing, guaranteed the creepage distance of lead-in wire to nail pressing.
