The invention provides a pressure-resistant test method of a composite electrode, which relates to the field of electric dehydration and desalination of crude oil. The pressure-resistant test method of the composite electrode comprises the following steps: step 1, connecting the internal components composed of the composite electrode and the high-voltage connection box Put it into the transparent working condition simulation box; Step 2, connect the test power supply to the metal terminal of the composite electrode in the high-voltage connection box, and connect the ground wire to the high-voltage connection box; Step 3, pour the medium into the transparent working condition simulation box until there is no pass the composite electrode; Step 4, pour transformer oil into the high-voltage connection box; Step 5, energize the test power supply, adjust the test power supply voltage, and perform a withstand voltage test. The withstand voltage test method of the composite electrode of the present application solves the technical problem of potential safety hazards in the electric dehydration and desalination equipment in the prior art.
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...
