Abstract

The invention discloses an animal modeling device for simulating the electric field exposure of an extra-high-voltage direct current power transmission line. The animal modeling device comprises a direct current ion flow generation unit, a static electric field generation unit, a voltage generation and control unit and an animal feeding cage, wherein the direct current ion flow generation unit comprises a corona wire mesh, a control grid mesh and a ground potential pole plate which are sequentially mounted on an insulating bracket; the ground potential pole plate is grounded; the static electric field generation unit comprises the ground potential pole plate and a plurality of upper pole plate meshes which are mounted on the insulating bracket, are positioned between the control grid mesh and the ground potential pole plate and are connected in series through a wire; the voltage generation and control unit comprises three direct current power supplies and a voltage control unit; the three direct current power supplies are connected with the corona wire mesh, the control grid mesh and the upper pole plate meshes respectively; the voltage control unit is connected with and controls the three direct current power supplies; the animal feeding cage is arranged on the ground potential pole plate. According to the animal modeling device, animal modeling for exposing a plurality of electric fields can be carried out at the same time, so that an electric field exposure environment is as close as possible to an electric field environment generated by the actual extra-high-voltage direct current power transmission line, an electric field exposure animal experiment of an extra-high-voltage direct current power transmission line is effectively carried out, and certain scientific reference is provided for corresponding standard setting.

Description

technical field [0001] The invention belongs to the field of biological model preparation, and in particular relates to an animal model-making device for simulating the electric field exposure of UHV direct current transmission lines. Background technique [0002] With the construction of UHV DC transmission projects and the continuous improvement of residents' requirements for their own environment, the related electromagnetic environmental impact has attracted much attention. Different from the time-varying electromagnetic field generated by the alternating current transmitted by the AC transmission line, the constant current transmitted by the DC transmission line generates a 0Hz time-invariant electric field (this part of the electric field is usually called the nominal electric field). , there is also an ion flow field generated by the corona discharge of the wire, and the two are superimposed to form a ground composite field strength. In some cases, the ground synthet...
