Description

Technical Field

[0001] The invention belongs to the technical field of vibration isolation devices, and in particular relates to an adaptive double-layer vibration isolation support for a reactor. Background Art

[0002] The reactor is the core inductive component of the power system. Its main body is composed of a coil and an iron core. According to the difference in magnetic circuit design, it can be divided into iron-core reactors and air-core reactors. Iron-core reactors use stacked silicon steel sheets to enhance the magnetic field, while air-core reactors have no magnetic conductive materials and rely on air magnetic circuits. In substations, reactors are usually installed in a vertical, horizontal or herringbone structure, and are connected to the circuit in series or parallel to achieve key functions such as short-circuit current limitation, reactive power compensation and voltage stability, harmonic control and overvoltage suppression.

[0003] During operation, the alternating current flowing through the reactor's coils generates a time-varying magnetic field, inducing magnetostriction in the core's silicon steel laminations—a periodic deformation—and generating alternating electromotive force acting on the windings. When the current has high harmonic content, high-frequency electromagnetic forces exacerbate the vibration amplitude. Components such as coil fixing bolts and core clamps can loosen due to prolonged vibration, leading to localized resonance and further amplifying vibration and noise. Furthermore, the operation of auxiliary equipment such as cooling fans also contributes to high-frequency mechanical noise. Abnormal reactor vibration and noise not only pollute the environment but also threaten system safety. Long-term vibration can cause winding insulation wear, core lamination shifting, connector fatigue fracture, accelerate equipment aging, and even cause short-circuit failures. Vibration can also loosen fasteners, increase contact resistance, and lead to localized overheating. In severe cases, this can trigger cascading failures, such as coil deformation leading to interturn shorts.

[0004] Patent application number CN202411845013.9 discloses an adaptive double-layer vibration isolation support for a reactor. The support comprises, from bottom to top, damping isolation pads, I-section steel, a base plate, a variable stiffness system, and a top plate. The top plate is equipped with the reactor, a vibration monitoring device, and a stiffness calculation device. The variable stiffness system includes a coarse stiffness adjustment system, a fine stiffness adjustment system, and a scissor jack system. The coarse stiffness adjustment system consists of vertically arranged coarse stiffness adjustment springs with stepped lengths. The fine stiffness adjustment system includes horizontally arranged longitudinal cylindrical helical springs. A motor-driven torque multiplier and worm mechanism adjust the horizontal and vertical endpoint distances of the scissor jacks, adjusting the type and compression and extension lengths of the springs involved in vibration control. Compared with existing technologies, the present invention achieves precise and efficient adaptive adjustment of the support's vibration isolation stiffness, overcoming the limitation of existing technologies that required separate vibration isolation supports for different reactor devices. However, the overall structural height will change during use, which requires that other equipment and auxiliary components connected to the reactor must also change accordingly. This is not practical in the actual use of supporting the reactor. Therefore, it is necessary to provide an adaptive double-layer vibration isolation support for the reactor.
