Abstract
A high-precision voltage divider relates to the field of the voltage divider manufacturing and comprises a cylindrical metal shell, an inner electrode, an outer electrode, a sealing leading-out terminal, wherein the outer electrode is coaxially arranged in the metal shell by an insulating support; the inner electrode is coaxially arranged in the outer electrode; a sealing electrode leading-out terminal is arranged on the external surface of the metal shell; a capacitive divider is provided with the inner electrode and the outer electrode in the cylindrical metal shell; the shell is injected with SF6 gas to form a cylindrical capacitor; the inner electrode is connected with the high pressure; the outer electrode is grounded so as to shield the influence of the coupling capacitance between a cylinder and the ground on the divider; and since the electrode material under the influence of the temperature variation has very low expansion coefficient, therefore, the precision of the capacitance is guaranteed.
Description
Technical field
The present invention relates to a kind of manufacturing field of voltage divider.
Background technology
Existing capacitor voltage divider, playing structure is vertically to be provided with, highly higher, floor space and institute take up space bigger, along with developing rapidly of high pressure GIS switch, from the convenience of test, originally constructed products can't satisfy the test requirements document of GIS switch, and bigger structure also causes the increase of cost.
Summary of the invention
Higher in order to solve existing capacitor voltage divider structure, take up room and the big problem of area, the invention provides a kind of high accuracy voltage divider.
The present invention includes cylindrical metal housing, interior electrode, external electrode, sealing leading-out terminal, described external electrode is arranged in the described metal shell by insulating support is coaxial, electrode is coaxial in described is arranged in the described external electrode, and the enclosed electrode leading-out terminal is set on the outer surface of described metal shell.
Internal and external electrode is set in cylindrical housings, in housing, injects SF
6Gas constitutes cylindrical capacitor, interior electrode connects high pressure, and external electrode ground connection, external electrode ground connection are in order to shield coupling capacitance between cylinder and the ground to the influence of voltage divider, because of electrode material has the extremely low coefficient of expansion under influence of temperature change, thereby guaranteed the precision of electric capacity.
