This utility model relates to the technical field of power equipment layout systems, and more particularly to a four-coil 500kV line series reactor layout system. The system includes a coil group comprising a first coil, a second coil, a third coil, and a fourth coil, arranged in a positive direction. The line of the series reactor is introduced into the first coil via a busbar, sequentially passes through the second and third coils, and is led out to the line from the fourth coil. The series reactor is a dry-type hollow reactor. By implementing this utility model, the system can effectively install reactors in series reactor stations in the middle section of a 500kV transmission line and in substations at both ends of the line, thus solving the shortcomings of the prior art and meeting the needs of power grid structure optimization and short-circuit current control.

This invention relates to a scraping and kneading massage mechanism, comprising a rotating base, at least one scraping ring and at least one kneading wheel disposed on its outer periphery. The scraping ring is composed of multiple scraping protrusions arranged at circumferential intervals and rotates synchronously with the rotating base. The kneading wheel includes a wheel body with multiple kneading protrusions on its outer periphery. A synchronously rotating transmission groove is located on the outer periphery of the rotating base. The kneading wheel body is inclined and rotates within the groove. The kneading wheel is inclined relative to the scraping ring, causing the opening and closing gap between the kneading wheel and the scraping ring to vary circumferentially. The rotating base is connected to a power drive mechanism, which drives the scraping ring to rotate. Each scraping protrusion moves circumferentially to perform scraping. Due to the contact and limitation between the kneading protrusions and the human body, the rotation of the transmission groove causes the kneading wheel to open and close, achieving opening and closing kneading. This mechanism can simultaneously perform rolling scraping and kneading massage, enriching the forms and enhancing the experience.
