Description

Technical Field

[0001] The present invention relates to the technical field of pressure equalizing rings, and in particular to an adaptive wind-resistant pressure equalizing ring and a control method for high wind load areas. Background Art

[0002] With the widespread adoption of ultra-high voltage and ultra-high voltage transmission technologies, most ultra-high voltage grid equipment is equipped with grading rings to improve the electric field distribution of power equipment, thereby helping to improve the unevenness of low-voltage electric fields and suppress the occurrence of discharge. The basic working principle of the grading ring is to use the electric field distribution effect of the conductor to expand the relatively concentrated electric field around insulators and switches outward, making the surrounding electric field distribution more uniform, thereby preventing high-voltage system problems such as corona and flashover. The grading ring is a ring-shaped protective hardware that improves the voltage distribution of the insulator string. The function of the grading ring is to protect against side lightning strikes. It is suitable for AC voltage. It can evenly distribute high voltage around the object, ensuring that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage balancing.

[0003] In the existing technology, the pressure equalizing ring used in high wind load areas will be broken by strong winds for a long time due to its own rigid setting. That is, the adaptive wind resistance of the pressure equalizing ring is poor, and it needs to be frequently repaired and replaced. For this reason, we propose an adaptive wind-resistant pressure equalizing ring for high wind load areas. Summary of the Invention

The rings are fixedly connected by bolts. The outer side of the guide ring 12 is processed with a precision bearing mounting surface for installing the magnetofluid bearing 2. The magnetofluid bearing 2 adopts the sealed structure of the existing technology and is filled with magnetofluid medium inside, which can realize low-friction rotation of the connecting frame 3. The connecting frame 3 is an annular frame structure made of stainless steel. Its inner side is fixedly connected to the outer ring of the magnetofluid bearing 2, and a plurality of mounting positions are evenly distributed on the outside for fixing the adaptive wind-resistant part 4. The protective shell 5 is made of engineering plastic and is fixed to one side of the connecting frame 3 by bolts, and the main components of the intelligent control part 6 are accommodated inside.

[0035] The adaptive wind-resistant part 4 includes a drive motor 41, a gear transmission system and a guide vane assembly. The drive motor 41 is a waterproof stepping motor and is fixed to the top inner side of the protective shell 5 through a mounting base. The output shaft of the drive motor 41 is connected to gear 1 42, and gear 1 42 is meshed with the inner gear ring 43. The inner gear ring 43 and the outer gear ring 44 are fixedly connected by bolts to form a composite gear structure. Eight gear 2s 45 are evenly distributed on the outer periphery of the outer gear ring 44. A guide vane 46 is fixedly installed on the rotating shaft of each gear 2 45. The guide vane 46 is made of carbon fiber composite material, and an array of micro vortex generators is embedded in its outer surface.
