Box-type substation and construction method thereof

Abstract

The invention provides a box-type substation and a construction method thereof, and relates to the technical field of substations. The box-type substation comprises a high-voltage distribution line box, a low-voltage distribution line box and a transformer line box; the transformer line box is located between the high-voltage distribution line box and the low-voltage distribution line box; the end, buried in the ground, of the transformer line box is communicated with the high-voltage distribution line box and the low-voltage distribution line box in a sealed mode. The high-voltage distribution line box, the low-voltage distribution line box and the transformer line box which are buried underground are arranged on the ground, so that the reasonable layout of the box-type substation in space is realized, the occupied area of the box-type substation can be greatly reduced; the high-voltage distribution line box, the low-voltage distribution line box and the transformer line box can be prefabricated in a factory, so that the steps of on-site construction and installation can be reduced; the difficulty of construction engineering is reduced, the cost is reduced, and the technical problems that a box-type transformer substation in the prior art is large in occupied area, inconvenient to overhaul and poor in environmental adaptability are solved.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a box-type substation and a construction method thereof. Background technique [0002] The box-type substation is a substation that organically combines functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution, and is installed in a fully enclosed, movable steel structure box. Box-type substation (referred to as box-type substation) is a compact complete set of high-voltage switchgear distribution transformers, low-voltage switchgear, electric energy metering equipment and reactive power compensation devices combined in one or several boxes according to a certain wiring scheme. Electrical device, it is suitable for rated voltage 10 / 0.4KV three-phase AC system, as a line and distribution of electric energy, box-type substation has strong complete set, short power transmission cycle, strong environmental adaptability, convenient ...
