Box-type substation which is convenient for replacing transformers

Abstract

The invention discloses a box-type substation which is convenient for replacing transformers. The box-type substation comprises a box body, a base at the bottom of the box body, and a top seat on theupper part of the box body, wherein the inside the box body is divided into a high-voltage chamber, a transformer chamber and a low-voltage chamber in turn from left to right; a high-voltage switchgear is arranged in the high-voltage chamber; a low-voltage switchgear is arranged in the low-voltage chamber; two symmetrical guide rails are arranged in the transformer chamber; positioning blocks located at the inner side ends of the two guide rails are also provided; a detachable transformer which can move linearly along the guide rails is further provided; and a butt locking device for locking and fixing the transformer to finish electrical connection with the high-voltage switchgear and the low-voltage switchgear respectively is further provided. This design makes the transformer more convenient to replace, thereby reducing the maintenance time of the substation and ensuring the normal use of power.

Description

technical field [0001] The invention relates to the technical field of box-type substations, in particular to a box-type substation that facilitates the replacement of transformers. Background technique [0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution device arranged according to a certain wiring scheme, which is to organically combine functions such as transformer step-down and low-voltage power distribution. Together, they are installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box, which is especially suitable for urban network construction and transformation. A brand new substation. The box-type substation is suitable for mines, factories,...

AI Technical Summary

Problems solved by technology

[0003] The box-type substation in the prior art includes a box body, high-voltage switchgear, low-voltage power distribution equipment, and a transformer. The transformer is large in size and heavy in weight. Once the transformer has a problem and needs to be replaced, it is very troublesome and difficult to replace. , and time-consuming and labor-intensive, thus affecting the transmission and use of electric power for a long time
