Integrated feedthrough for high voltage cables

An integrated feedthrough for high voltage cables, comprising a glue filling device and a high voltage feedthrough:

• wherein the glue filling device comprises a lower clamping cover plate, an upper clamping cover plate, a compression collar, a compression nut, a high voltage plug, a high voltage blind flange socket and a high voltage cable in a coordinated manner;
• the upper clamping cover plate and the lower clamping cover plate are connected by a second bolt, and a glue filling cavity is formed inside;
• the high voltage blind flange socket cooperates with a tapered groove inside the high voltage plug and a thread structure outside through a W-shaped groove and a thread structure inside to form a high voltage joint;
• the glue filling cavity cooperates with the high voltage joint, the compression collar and the compression nut to seal both front and rear ends of the glue filling cavity to prevent an insulating glue from overflowing;
• after the insulating glue is allowed to stand for curing, the high voltage plug and the high voltage cable sealed by the insulating glue are taken out;
• and
• the high voltage feedthrough comprises a feeder pillar, a high voltage sealing plug, a flange, a seal ring, threaded rods, a pressing plate and nuts in a coordinated manner;
• both the high voltage plug and the high voltage cable sealed by the insulating glue are inserted into a tapered high pressure channel structure of the feeder pillar;
• the high voltage sealing plug and the high voltage blind flange socket are matched with the high voltage plug at an upper end of the feeder pillar, they are fastened by a first bolt;
• the compression collar is matched with the high voltage cable at a tail of the feeder pillar, and the two are fastened by thread fitting between the compression nut and the tail of the feeder pillar;
• the flange is matched with the feeder pillar, the two are fastened by the threaded rods, a pressing plate and nuts, and a seal ring between the flange and the feeder pillar is extruded to deform the seal ring and seal the vacuum fed by the feeder pillar;
• high voltage is fed into the target through the high voltage feedthrough to realize insulation and sealing of the high voltage plug and avoid high voltage sparking.
