Abstract

The invention relates to a high-voltage resistor type voltage dividing device, comprising a voltage dividing device body, a resistor layer, a buffering film, a high-voltage electrode and a grounding electrode, wherein the voltage dividing device body is in a cylindrical shape; the resistor layer covers the outside of the voltage dividing device body and is used for carrying out equal potential shielding on the voltage dividing device body; the buffering film covers the outside of the resistor layer and enables the voltage dividing device to have sticking and anti-stress performances; the high-voltage electrode is arranged at one end of the voltage dividing device body, which is connected with a high-voltage lead wire, in an upper cover shape, and is used for receiving a voltage signal sent by the high-voltage lead wire; and the grounding electrode is arranged on a grounding end of the voltage dividing device body in a lower cover shape and is used for replacing a ground wire. According to the high-voltage resistor type voltage dividing device, technical measures including compensation, shielding and the like are adopted for the voltage dividing device, so that the standard output of the voltage dividing device is guaranteed.

Description

technical field [0001] The invention relates to a voltage divider, in particular to a high-voltage resistance type voltage divider, and belongs to the technical field of components used in the electric power industry. Background technique [0002] On-line high-voltage (10kV, 35kV) measurement, monitoring and protection, often use an electronic transformer with resistance voltage divider technology to replace the traditional electromagnetic voltage transformer, because of its small size, light weight, unsaturated, non-toxic There are many advantages such as ferromagnetic resonance and wide frequency bandwidth. But why can't this kind of electronic transformer completely replace the traditional electromagnetic transformer? In addition to national policies, usage habits, supporting facilities and other reasons, the most important point is that electronic transformers using resistance voltage divider technology still have many imperfections, such as poor stability, large temper...
