Abstract

The invention relates to a self-tight-sealing high voltage introduction bar, belonging to the technical field of electric desalting and electric dewatering facilities in crude oil pretreatment. The self-tight-sealing high voltage introduction bar comprises a bar cap and a bar body, wherein a screw plug, a cable, a high-voltage-resistant heat-shrinkable pipe, a liner and a liner sleeve are arranged in the bar cap and bar body. The structure also comprises a self-tight seat, a connecting flange, a sealing element, a connecting bolt and a nut, wherein the connecting flange, sealing element and connecting bolt are matched with the seat. The high-voltage-resistant heat-shrinkable pipe is wrapped outside the cable to effectively prevent the surface climbing arc ablation on the cable surface due to dielectric pollution. The lower end of the bar body is provided with an umbrella-shaped structure to increase the insulation distance on the lower part, thereby avoiding the ablation of the electrode introduction bar cap in the long-term electrical discharge arc process, and further prolonging the service life. The self-tight seat, connecting flange and sealing element are combined to form the self-tight sealing structure of which the sealing effect is suitable for high-voltage vessels, thereby preventing the high-voltage vessels from losing effects due to sealing leakage in the operation process.

Description

technical field [0001] The invention belongs to the technical field of electric desalination and electric dehydration equipment in the process of crude oil pretreatment, and particularly relates to a high-voltage electric introduction rod, a key component for introducing high-voltage electricity into an electric field in a complete set of electric desalination and electric dehydration equipment. Background technique [0002] With the complexity of crude oil products, the corrosion of equipment in the pretreatment process is also becoming more and more serious. In order to reduce the corrosion of equipment and prolong the service life of catalysts, crude oil desalting is an indispensable measure for petrochemical and refinery companies to pretreat crude oil. Various fuel oils obtained after primary and secondary processing of crude oil often contain impurities such as sulfur and nitrogen. These impurities affect the quality of oil products and cause serious corrosion to equip...
