Summary of the invention
Technical problem to be solved by this invention is; Overcome the weak point of prior art; Provide to satisfy and utilize dry air or nitrogen insulation, and can effectively shield non-uniform electric field, improve a kind of dish formula bus casing of dish formula sleeve pipe withstand voltage level because of the existence generation of impurity.
The technical scheme that the present invention adopts comprises insulator, mounting flange and copper electric conductor; The matrix of said copper electric conductor is a cylinder; Being connected with up and down at the matrix middle part of copper conductor through spoke, 2 cross sections are circular ring shielding ring; Said insulator is the dish formula structure with annular projection of upper and lower surfaces symmetry, and the axial cross section of said annular projection is a circular arc.
On insulator, form 2 concave surfaces, one is first concave surface of insulator intermediate surface and copper electric conductor transition position, and another is second concave surface of insulator surface and annular flange transition position.
Compared with prior art, the invention has the beneficial effects as follows:
(1) annular shading ring is installed through spoke and insulator is a butterfly revolving body symmetrical structure in the present invention middle part of being employed in cylindrical, copper conductor matrix; The insulator upper and lower surfaces has annular projection; Make to form 2 concave surfaces on the insulator, one is first concave surface of insulator intermediate surface and copper electric conductor transition position, and another is second concave surface of insulator surface and annular flange transition position; The present invention is insulated reliably, electric field is even, shield effectiveness good thereby make; If insulator intermediate surface and copper electric conductor transition position have impurity such as metal fillings,, can effectively shield the non-uniform electric field that produces because of impurity through the effect of the shading ring on the copper electric conductor in the insulator; If insulator surface and annular flange transition position have impurity such as metal fillings, can make the electric field on dish formula bus casing surface not receive the influence of impurity such as metal fillings through the shielding action of mounting flange, thereby improve withstand voltage level; Insulator surface has the structure of annular projection; Automatically slide in first concave surface of insulator intermediate surface and copper electric conductor transition position after can making moving component produces in the upper chamber metal fillings fall on the dish formula sleeve pipe and in second concave surface of insulator surface and annular flange transition position; Promptly slide to automatically in the shielding area of copper electric conductor shading ring and annular flange, make the existence of metal fillings can excessively not influence the withstand voltage level of insulator surface.
(2) the copper electric conductor is cylindrical shape, and is simple in structure, easy to process, and can save the copper rod material.
