Description

Technical Field

[0001] The invention relates to the technical field of box-type transformer substations, and in particular to a box-type transformer substation with adjustable anti-seismic buffering and an adjustment method thereof. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment.

[0003] The box-type substation in the prior art is generally fixed directly on the ground, and there is no device to buffer and resist shock.

[0039] The present invention also proposes a box-type substation adjustment method with adjustable seismic buffer, comprising the following steps:

[0040] S1, placing, fixing the base 1 at the place to be installed, sleeve the mounting plate 6 on the outer wall of the plurality of fixing rods 17, and adjusting the supporting strength of the plurality of supporting springs 18 on the mounting plate 6;

When the substation body 3 vibrates, the sliding connection between the mounting plate 6 and the plurality of fixing rods 17 will cause the mounting plate 6 to move downward. At this time, the plurality of supporting springs 18 will initially offset the vibration on the mounting plate 6, and through the rotational connection of the rotating plate 10 between the plurality of fixing seats 14 and the connecting seats 9 between the mounting plate 6 and the plurality of connecting plates 8, the mounting plate 6 moves downward, causing the plurality of rollers 15 to move in the two moving grooves 7, and under the action of the telescopic rod 11 and the buffer spring 12 between the side plate 13 and the moving groove 7, the movement of the plurality of rollers 15 is buffered, thereby achieving the buffering and shock reduction of the vibration formed by the substation body 3, and preventing the vibration from directly acting on the substation body 3 and causing damage to the electronic components inside it;
