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

The invention discloses a box-type substation for convenient transformer replacement, which includes a box body, a base set at the bottom of the box body, and a top seat set at the top of the box body; the inside of the box body is divided into High-voltage room, transformer room, and low-voltage room; the above-mentioned high-voltage room is provided with a high-voltage switchgear; the above-mentioned low-voltage room is provided with a low-voltage switchgear; the above-mentioned transformer room is provided with two symmetrically arranged guide rails, and a The positioning block is also provided with a docking locking device for locking and fixing the transformer, and the locking and fixing transformer is also electrically connected with the high-voltage switchgear and the low-voltage switchgear respectively. This design makes the replacement of the transformer more convenient, 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,...
