Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformers, and more specifically to a transformer with an anti-vibration base. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for voltage step-up / step-down, impedance matching, and safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electromotive force is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the number of magnetic fluxes linked to the coil changes; this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.
[0003] Existing transformers mainly consist of a core, windings, and an oil tank. The core is made of magnetic material covered with insulating material, used to strengthen and concentrate the magnetic field. The windings are composed of wires wrapped with insulating material, and are divided into primary and secondary windings. The primary winding is connected to the power source and receives electrical energy input; the secondary winding outputs the required electrical energy. The oil tank is a container filled with transformer oil, used for cooling and insulation. However, this type of transformer lacks a dedicated vibration damping structure. Under strong earthquakes, it can suffer three types of damage: static damage, dynamic damage, and malfunction of protective devices (such as gas relays). This can lead to varying degrees of overall displacement, toppling, or damage to components such as bushings; it can also cause disasters such as fires and power outages.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention
[0005] To improve or solve the technical problem of transformers in the prior art lacking dedicated shock-absorbing structures and being easily damaged by strong vibrations, this utility model provides a transformer with a shock-resistant base. The transformer with a shock-resistant base includes: a transformer box having a bottom; a base installed below the bottom of the box, and multiple bases thereon; the base includes a mounting seat, a core seat floating within the mounting seat, and a rubber pad disposed between the core seat and the mounting seat; the core seat is fixedly connected to the bottom of the box, and a limiting member is provided on the mounting seat to prevent the core seat from shaking.
[0006] The transformer with an anti-vibration base of this invention includes a transformer box and a base. The transformer box has a bottom. The base is located below the bottom of the box and supports the transformer box. The base includes a mounting seat, a core seat, and a rubber pad. The mounting seat is connected to the transformer mounting plane and is used to mount the core seat and the rubber pad. The core seat is floatingly arranged within the mounting seat and is fixedly connected to the bottom of the box. The rubber pad is arranged between the core seat and the mounting seat. When the transformer box vibrates, the core seat vibrates accordingly. The rubber pad reduces the impact force generated by the vibration between the core seat and the mounting seat, preventing damage to the base, and thus preventing overall displacement, tilting, and structural damage to the transformer box. A limiting member is provided on the mounting seat to prevent the core seat from wobbling within the mounting seat, enhancing the stability of the limiting member and the mounting seat. Through the above-described design, this invention, by incorporating the core seat and the rubber pad, reduces the impact force generated by vibration between the transformer box and the mounting seat, preventing damage to the base, and thus preventing overall displacement, tilting, and structural damage to the transformer box.
[0007] In the preferred embodiment of the transformer with an anti-vibration base described above, the limiting member is a limiting bolt; the mounting base includes a base plate and a circumferential plate connected to the base plate; a plurality of limiting holes that match the limiting member are spaced apart along the circumference of the circumferential plate. Through the above arrangement, the limiting member and the limiting holes can conveniently limit the movement of the core seat.
[0008] In the preferred embodiment of the transformer with an anti-vibration base described above, the core seat includes a main body and a limiting ring mounted on the main body; the diameter of the limiting ring matches the diameter of the circumferential plate, and the limiting ring is located between the base plate and the limiting member. Through this arrangement, the limiting ring, positioned between the base plate and the limiting member, prevents the core seat from floating significantly within the mounting base.
[0009] In the preferred embodiment of the transformer with the anti-vibration base described above, an embedding groove matching the rubber pad is provided below the main body. This design, where the embedding groove matches the rubber pad, prevents the rubber pad from wobbling within the mounting base.
[0010] In the preferred embodiment of the transformer with the anti-vibration base described above, a fixing plate is further included, which is sleeved on the outer side of the core seat. The fixing plate is fixedly connected to the core seat and to the bottom of the tank.
[0011] In the preferred embodiment of the transformer with an anti-vibration base described above, the fixing plate is fixedly connected to the core seat by welding, and the upper side of the fixing plate facing the bottom of the transformer tank and the upper side of the core seat facing the bottom of the transformer tank are coplanar. This coplanar arrangement of the fixing plate and the core seat provides better support for the transformer tank.
[0012] In the preferred embodiment of the transformer with an anti-seismic base described above, the fixing plate is fixedly connected to the bottom of the tank by bolts. This bolted connection method offers a simple structure and high reliability. Attached Figure Description
