Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, in particular to an earthquake-resistant American box-type transformer substation. Background Art

[0002] The transformer room is where the transformer is placed. With the progress of society and the continuous improvement of electrification, the power supply capacity and distribution and transformation equipment have shown that the capacity is insufficient or the transformer is overheated more and more frequently. The development of the transformer room is also indispensable to maximize the role of existing equipment, reduce equipment failure rate, and provide high-quality, stable, continuous and reliable power supply.

[0003] At present, an earthquake-resistant American-style box transformer is generally installed outdoors. Due to the uncertainty of the installation environment, it is necessary to press down on the transformer room to build the foundation. However, the foundation is generally built in a hollow state to facilitate ventilation and heating. As a result, the bottom of the transformer room is suspended except for contact with the foundation, and is unable to contact the bottom surface. Therefore, stability and reliability need to be further improved. Utility Model Content

[0004] In view of the above problems, the utility model provides an earthquake-resistant American box transformer. After placing the transformer room on the foundation, the force pad is knocked on the stabilizer component, and the internal ground column is directly inserted into the ground, so that the direction hook contacts the ground surface, so that the transformer room is more stably and reliably seated on the foundation, thereby ensuring the stability of the transformer room.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: an earthquake-resistant American box transformer, including a transformer room, the four corners of the lower surface of the transformer room are installed with anti-deflection sleeves, the transformer room is provided with a room frame inside, the surface of the room frame is provided with a transformer bracket for storing the transformer, and the four corners of the surface of the room frame are provided with a stabilizing component for reinforcement; a fixed box is provided in the stabilizing component, the top of the fixed box is covered with a box cover, a force pad is provided on the box cover, a ground column is provided in the middle of the lower surface of the force pad, a slide groove is provided on the surface of the fixed box, a plurality of inner screw sleeves are fixed on the inner wall of the fixed box, an auxiliary sleeve is stored in the fixed box, a reverse hook for reinforcement is provided at the end of the ground column, and an anti-deflection rod is provided above the reverse hook. One of the top ends of the ground column is triangular pointed, which is convenient for insertion into the ground surface, and the reverse hook provided on the end is reversely engaged with the ground after the ground column is connected to the ground surface, so as to ensure that the stability of the transformer room after it is seated on the foundation is further improved.

[0006] Furthermore, the auxiliary sleeve surface is provided with a barrel side slide groove at a position opposite to the slide groove, the auxiliary sleeve inner wall is provided with a plurality of card slide grooves, an inner chuck is installed between the auxiliary sleeve and the card slide groove, and a pressure spring is arranged above the inner chuck. The pressure spring is mainly used to close the inner chuck, and has a reverse thrust on the ground-inserting column connected to the inner chuck, so that the ground-inserting column can be firmly and reliably inserted into the ground surface, and the ground-inserting column will not rise in the opposite direction due to external factors.

[0007] Furthermore, the auxiliary sleeve is fixed inside the fixing box, the pressure spring is nested on the ground-inserting column, and partly penetrates below the fixed inner chuck, and the fixing box is fixed to the box cover bolts through the inner screw sleeve. The auxiliary sleeve is mainly used to assist the ground-inserting column to remain vertically downward, so that the force pad connected to the top of the ground-inserting column can remain vertically inserted into the ground surface when it is struck.

[0008] Furthermore, the anti-bias rod passes through the cylinder side slide groove and the slide groove in sequence, four insertion rods are arranged below the force pad and pass through the box cover, a part of the ground-inserted column passes through the anti-bias sleeve, and the fixed box is fixed to the surface of the room frame by bolts. The anti-bias sleeve is mainly arranged at the bottom of the room frame in the transformer room, and is located inside the foundation, so that when the ground-inserted column contacts the ground surface downward, it can directly maintain verticality, assisting it to complete vertical extension and insert into the ground surface.

[0009] Beneficial Effects

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model installs the stabilizing components at the four corners inside the room frame, and then knocks the force pad after the room frame is seated on the foundation, so that the ground column extends downward, thereby adapting to the downward pressing of the internal pressure spring. At the same time, in the process of downward contact with the ground surface, the ground column is assisted by the card slide groove, the slide groove and the anti-bias sleeve, which ensures that the ground column is in vertical contact with the ground surface, so that the transformer room can be more stably and reliably seated on the foundation, thereby ensuring the stability, seismic resistance and reliability of the transformer room.
