Description

Technical Field

[0001] The invention relates to the technical field of transformer installation, and in particular to a transformer installation structure. 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, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Transformers can be divided into the following categories according to their uses: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc.

[0004] When installing a transformer, it is necessary to adjust the position of the transformer so that the connection hole on the transformer is aligned with the fixing hole on the mounting platform. The existing alignment adjustment method is: lift the transformer onto the mounting platform in advance, and then multiple people work together to repeatedly adjust the position of the transformer by pushing and pulling until the connection hole is aligned with the fixing hole on the mounting platform. Since the transformer is heavy and there is a large friction between the transformer and the mounting platform during the dragging process, on the one hand, it causes wear on the transformer, and on the other hand, the workers have high labor intensity and are time-consuming and laborious during the alignment adjustment.

[0005] Based on the above technical problems, the inventor proposed a transformer installation structure based on the structural characteristics of the transformer itself and the on-site installation layout. The transformer can be lifted up by a lifting device to separate it from the table top of the installation platform, and the transformer position can be flexibly adjusted based on the universal wheel, so that the connection hole can be easily aligned with the fixing hole on the installation platform. The installation process eliminates the need for manual pushing and pulling, has a simple structure, is easy to adjust, and saves time and effort. Summary of the invention

[0006] The present invention aims at solving the deficiencies of the prior art and provides a transformer installation structure.

[0011] Preferably, the fastener is a fastening bolt, which is threadedly connected to the sleeve and used to tighten the transverse connecting beam. The sleeve can slide along the transverse connecting beam based on the tightness adjustment of the fastener, and then the position of the plug can be adjusted according to the position of the support tube, so as to facilitate the smooth plugging of the plug and the support tube.

[0012] Preferably, in order to adapt to different types of transformers, long holes are provided at both ends of each longitudinal connecting beam, and connecting screws are respectively fixed at both ends of each transverse connecting beam.
