Description

Technical Field

[0001] The utility model relates to the technical field of transformer earthquake resistance, in particular to an earthquake resistance structure for a transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to their uses, they can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, industrial frequency test transformers, voltage regulators, mining transformers, audio transformers, medium frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.) Transformers are mainly installed outdoors. When the transformer works efficiently for a long time, vibrations often occur, and the outdoor ground often vibrates due to external factors.

[0003] A transformer seismic structure described in publication number CN215673357U includes a seismic structure main body, a control module is fixedly installed on the outer surface of the seismic structure main body, a transformer fixed seismic device is arranged above the seismic structure main body, a transformer bottom seismic device is arranged below the transformer fixed seismic device, and the transformer fixed seismic device includes a motor, a threaded rod and a clamping mechanism, and one end of the threaded rod is fixedly connected to the output end of the motor. The utility model installs the transformer fixed seismic device, and the threaded rod makes the clamping mechanism move relatively toward the middle to fix the transformer in the middle. The shock absorbing spring, I-type rubber plate and pressure-resistant plate provide multi-directional shock-absorbing structural support for the transformer, and the installation is convenient, thereby solving the problems that the transformer seismic device cannot provide multi-directional shock absorption for the transformer and the shock absorption support structure is inconvenient to install. However, the prior art still has defects:

[0004] The transformer anti-seismic structure adopted in the prior art utilizes a threaded rod to move two sliders toward or away from each other, so as to facilitate the fixation of transformers of different sizes. When vibration occurs, generally lateral and longitudinal vibrations coexist, and the shock absorbing effect of the transformer is not good enough only by the sliders on both sides and the shock absorbing springs on both sides.

Baffles 11 are provided on the front and back of one side of the upper end of the outside of the base 1, and a worm 12 meshing with the worm gear 9 is provided between the baffles 11. The worm gear 12 can drive the worm gear 9 to rotate, and conversely, the worm gear 9 cannot drive the worm gear 12 to rotate.
