[0002] The reactor is an inductive high-voltage electrical appliance used in power systems to limit short-circuit current, reactive power compensation and phase shifting. The magnetic flux forms a circuit through the air. It is mainly divided into hollow series reactors, hollow filter reactors, hollow shunt reactors, hollow current limiting reactors, hollow split reactors, hollow starting reactors, etc. It is often used in reactive power compensation, harmonic filtering, current limiting and other occasions. When the reactor is running, a capacitor grading ring can be used to perform voltage grading operations on the capacitors inside the reactor.

The utility model discloses a pressure-equalizing ring structure suitable for windy areas, wherein the pressure-equalizing ring comprises a pressure-equalizing ring body I and a pressure-equalizing ring body II which are butt-jointed and assembled with each other; the pressure-equalizing ring body I and the pressure-equalizing ring body II are butt-jointed with each other through the step-shaped overlapping surfaces of the edges and then fastened by hexagon socket bolts; bolt holes for passing the hexagon socket bolts are provided at the positions corresponding to the overlapping surfaces of the pressure-equalizing ring bodies I and II; the top and bottom ends of the bolt holes are concave holes for embedding nuts and nuts of the hexagon socket bolts, and the aperture of the concave holes is larger than the aperture of the bolt holes; the pressure-equalizing ring is an annular structure, and four aluminum plates are evenly distributed around the center of the pressure-equalizing ring; the aluminum plate is an L-shaped structure, comprising a long plate extending along the radius of the pressure-equalizing ring and a short plate perpendicular to the long plate; four assembly holes are provided on the short plate; correspondingly, four convex wiring terminals for assembling with the short plate of the aluminum plate are installed on the pressure-equalizing ring.

[0004] Although the pressure equalizing ring in the prior art uses four aluminum plates evenly distributed at 90 degrees, which is more reliable than the traditional four aluminum plates distributed at 180 degrees, and will not break after practice. At the same time, the uniform distribution of the four aluminum plates of the utility model can increase the width of the aluminum plate to increase the strength, but there is a problem that the subsequent maintenance of the pressure equalizing ring is inconvenient and cannot be efficiently maintained.
