Abstract
The utility model relates to an insulating hoisting part for a mutual inductor. The insulating hoisting part is characterized by consisting of an insulating hoisting column and a metal connecting plate, which are connected, wherein one end of the metal connecting plate is tapered, and is positioned in the insulating hoisting column; a steel ball is arranged on the tapered top of the metal connecting plate; and a shielding part for point shielding is arranged on the peripheral wall of the insulating hoisting column opposite to the steel ball. The insulating hoisting part has the characteristics of simple structure, reliable performance and convenience for use; the steel ball is arranged on the tapered end part of the metal connecting plate, and a guide groove and a shielding spring are arranged on the insulating hoisting column opposite to the steel ball, so that the distribution of an electric field is improved, point discharge caused by the excessive concentration of the electric field is completely eliminated, the magnitude of partial discharge is reduced, the operating requirements of hoisting assembly and high product voltage level completely can be met, and the electrical performance of a voltage transformer is improved.
Description
Technical field
The utility model relates to a kind of transformer parts, assembles the insulation lifting part that transformer is used especially for lifting.
Background technology
Lift in the production process of assembling transformer at needs, lifting part adopts phenolic aldehyde cardboard or highly dense plate manufacturing usually, transformer iron core and winding are carried out unsettled assembling, phenolic aldehyde cardboard or highly dense plate serve as dielectric, the specific inductance capacity of its specific inductance capacity and transformer dielectric is inconsistent, and in conjunction with unreliable, the geometric configuration of lifting part can't be accomplished full-shield to high voltage electric field in addition, thereby cause electric-field intensity distribution uneven, easily cause electric property unstable, especially local discharging level is difficult to the requirement that is up to state standards.Along with the development of transformer to miniaturization and voltage levels direction, the size of insulation lifting part is corresponding reducing also, and traditional insulating hanging piece installing more can't be satisfied the electric property requirement, has a strong impact on the reliability of product.
Summary of the invention
The purpose of this utility model is to provide a kind of dependable performance, transformer insulation lifting part that the shelf depreciation voltage levvl is high.
The technical solution of the utility model is: a kind of transformer insulation lifting part, it is characterized in that it is connected and composed by insulation lifting post and metallic interconnect, metallic interconnect one end is tapered, and be positioned at insulation lifting post, the metallic interconnect tapered tip is provided with steel ball, and the insulation lifting post perisporium relative with steel ball is provided with the shield member of most advanced and sophisticated shielding.
The insulation lifting post perisporium relative with steel ball is provided with annular guide groove, is provided with the shield member for the tip shielding in the guide groove.
Described shield member is shielding spring.
The utility model has adopted metallic interconnect and the connecting portion that insulation lifts post has been designed to taper, tapered tip is connected with steel ball, arranging of steel ball can make the Electric Field Distribution of end even, prevent the metallic interconnect point discharge, simultaneously can also the reinforcement metal connecting panel lift reliable connection between the post with insulation, can not break away from because of Action of Gravity Field between the two.Be provided with annular guide groove at the insulation lifting post perisporium corresponding with the steel ball center, be provided with shield member in the guide groove, shield member and steel ball be centered close to same level, be used for optimizing the insulator internal electric field and distribute, and thoroughly with high tag shielding in high voltage electric field.The other end of metallic interconnect is used for being connected to iron core iron yoke.
Characteristics of the present utility model are: simple in structure, dependable performance, easy to use, by at the metallic interconnect tapered end steel ball being set, and at the insulation lifting post relative with steel ball guide groove and shielding spring are set, have improved Electric Field Distribution, thoroughly eliminated too to concentrate because of electric field and point discharge occurred, reduce partial discharge quantity, can satisfy the operating needs of lifting assembling and product voltage levels fully, improved the electric property of voltage transformer.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the insulating hanging piece installing is to be connected and composed by metallic interconnect 1 and insulation lifting post 2.Insulation lifting post adopts the epoxide resin material moulding by casting, and is identical with the material of transformer insulating protector.The tapered end of metallic interconnect is cast in the insulation lifting post, and tapered tip is welded with steel ball 3, and the other end is used for being fixedly connected on transformer iron core iron yoke.The insulation lifting post perisporium relative with steel ball is provided with annular guide groove 4, and the shield member that is provided with in the guide groove for the tip shielding is shielding spring 5.
