The invention provides a withstand voltage test method for a combined electrode, and relates to the field of electric dehydration and desalination of raw oil. The withstand voltage test method for the combined electrode comprises the steps that: step 1, an internal component formed by connecting the combined electrode and a high-voltage connecting box is placed in a transparent operating mode simulation box; step 2, a test power supply is connected with a metal end of the combined electrode in the high-voltage connecting box, and a grounding wire is connected with the high-voltage connecting box; step 3, a medium is poured into the transparent operating mode simulation box until the medium is over the combined electrode; step 4, transformer oil is pour into the high-voltage connecting box; and step 5, the test power supply is powered on, and the voltage of the test power supply is adjusted to carry out the withstand voltage test. The withstand voltage test method for the combined electrode solves the technical problems that the electric dehydration and desalination equipment in the prior art has potential safety hazards.
Description
technical field [0001] The invention relates to the field of electric dehydration and desalination of crude oil, in particular to a pressure resistance test method of a composite electrode. Background technique [0002] The traditional electric dehydration and desalination technology uses metal electrodes, but when the metal electrodes are used to control the electric field to separate the oil-water phases of the high water content / conductivity emulsion, the phenomenon of excessive current and tripping of the pressurization unit often occurs, and it is not easy to establish an effective one. Electric field, the water content index of crude oil after removal can not meet the requirements of crude oil export. [0003] In response to changes in crude oil production fluids, electrostatic coalescence / pre-coalescence technologies based on composite electrodes have emerged, such as coalescers such as CEC, IEC, and VIEC. However, during the use of the composite electrode, there are...
