Description
Technical field
The utility model relates to a kind of indoor epoxy resin pouring dry-type voltage inductor doing electric energy metrical and relaying protection use in electric power system.
Background technology
Along with the continuous expansion of China's power grid construction and transformer station's capacity-increasing transformation project, it is little to there is capacity in indoor epoxy resin pouring dry-type voltage inductor, and partial discharge quantity is large, and antifouling capacity is poor, the shortcomings such as dielectric strength is low, can not meet the user demand of modernization power grid construction.
Summary of the invention
The purpose of this utility model is to provide a kind of Large Copacity, high accuracy, and partial discharge quantity is little, and antifouling capacity is strong, and dielectric strength is high, and the indoor epoxy resin pouring dry-type voltage inductor of tool preventing fraudulent use of electricity function.
The utility model solves the technical scheme that its technical problem adopts: it is by insulator, iron core, high-low pressure winding, HV Terminal, secondary terminal box, base plate forms, a stem of iron core is set with high-low pressure winding, high pressure winding adopts two cylindrical section formula structures, screen is respectively equipped with at the upper semicircumference of two sections, insulator is according to interior shape, poured into a mould under vacuum by indoor epoxy resin and form, two HV Terminal are positioned at insulator top, four projections are provided with in the middle of two HV Terminal, cross section is trapezoidal, base plate is connected by screw with insulator bottom.
The purpose of this utility model also realizes further by following technical proposals.
Iron core rolls into rectangle by the silicon steel sheet band material of different in width, and its cross section is close to circle.
Multiple lead-out wires of low pressure winding are unified to be caused in the secondary terminal box of sealing.
Base plate is rectangle, and band four shape of a hoof installing holes.
The beneficial effects of the utility model are, iron core rolls into rectangle by the silicon steel sheet band material of different in width, and cross section is close to circle.In this kind of iron core, magnetic line of force direction is consistent with the spreading direction of electrical sheet, and activity coefficient is high, without seam, makes the Large Copacity of Realization of Product grid requirements, high-precision instructions for use.
High pressure winding adopts two cylindrical section formula structures, and is respectively equipped with screen at the upper semicircumference of two sections, while reduction voltage between layers, also improves the electric-field intensity distribution of interiors of products, reduces the partial discharge quantity of product.
Insulator, according to interior shape, is poured into a mould under vacuum by indoor epoxy resin and is formed, and product each position thickness of insulating layer is more or less the same, avoid resin bed thin and thick have big difference and cause insulating barrier cracking, also save raw material simultaneously.Be provided with four projections in the middle of two HV Terminal, cross section be trapezoidal, improve product along face creepage distance and dielectric strength, make product can safe operation under the environment of humidity, heavy pollution.
Base plate is rectangle, and band four shape of a hoof installing holes, simple installation is firm.
The multiple lead-out wires of low pressure winding are unified to be caused in the secondary terminal box that sealed by screw, the functions such as this terminal box tool is antitheft, rainproof, anti-filth.
